In a single-institution, double-blind, prospective, randomized trial, we determined whether oral aloe vera gel can reduce radiation-induced mucositis in head-and-neck cancer patients.
                We randomized 58 head-and-neck cancer patients between oral aloe vera and placebo. To be included in this Phase II protocol, patients had to be treated with radiotherapy with curative intent at Stanford University between February 1999 and March 2002. We examined patients biweekly for mucositis at 15 head-and-neck subsites and administered quality-of-life questionnaires.
                Patients in the aloe and placebo groups were statistically identical in baseline characteristics. By the end of treatment, the two groups were also statistically identical in maximal grade of toxicity, duration of Grade 2 or worse mucositis, quality-of-life scores, percentage of weight loss, use of pain medications, hydration requirement, oral infections, and prolonged radiation breaks.
                In our randomized study, oral aloe vera was not a beneficial adjunct to head-and-neck radiotherapy. The mean quality-of-life scores were greater in the aloe vera group, but the differences were not statistically significant. Oral aloe vera did not improve tolerance to head-and-neck radiotherapy, decrease mucositis, reduce soreness, or otherwise improve patient well-being. To evaluate the ability of granulocyte-stimulating factor to decrease mucositis during postoperative radiotherapy for stage II-IV squamous head and neck cancer in a randomized, double-blind, placebo-controlled trial.
                After undergoing complete resection, patients were randomized to receive granulocyte-colony stimulating factor or placebo by daily subcutaneous injection during radiotherapy (63 Gy, 1.8 Gy/day). Patients undergoing prior radiotherapy or chemotherapy were excluded from the study. The primary outcome was the need for percutaneous endoscopic gastrostomy placement. Severity of mucositis was a secondary outcome.
                Forty-one patients were enrolled (132 planned). The study closed after slow accrual. Patient characteristics were as follows (granulocyte-colony stimulating factor vs placebo): median age, 59 versus 54 years; pT4, 16% versus 23%; pN2/3, 68% versus 59%; stage IV, 79% versus 68%. Forty patients were evaluable for planned outcomes. Patients in the granulocyte-colony stimulating factor arm showed trends toward lower rates of percutaneous endoscopic gastrostomy placement (0% vs 14%, P = 0.2) and severity of mucositis (P = 0.13), and had shorter mean radiotherapy duration (48.4 +/- 4.32 days vs 51.6 +/- 1.84 days, P = 0.005). Overall survival was significantly greater in the granulocyte-colony stimulating factor arm (hazard ratio, 0.37; P = 0.037).
                Granulocyte-colony stimulating factor during radiotherapy was feasible and led to significantly shorter radiotherapy duration and trends toward less percutaneous endoscopic gastrostomy placement and mucositis. The unanticipated improvement in survival outcomes warrants further hypothesis-driven investigation and validation. The aim of this study was to assess whether amifostine could minimize acute mucositis induced by a very accelerated irradiation regimen in patients with advanced head and neck squamous cell carcinoma (HNSCC).
                Between May 1996 and February 1998, 26 patients with an inoperable nonmetastatic Stage IV HNSCC were entered in this study. The treatment consisted of very accelerated radiotherapy given 64 Gy in 3.5 weeks. The patients were randomized to receive or not 150 mg/m(2), amifostine (Ethyol, U.S. Bioscience) 15-30 min prior to each radiation session.
                Of the 13 patients who received amifostine, definitive interruption of amifostine occurred in 5 cases (38%), due to tolerance problems (vomiting, liver enzyme elevation, generalized erythema). The distribution of Grade 4 mucositis (WHO) was 1 case versus 8 cases, with and without amifostine, respectively. The mean duration of "at least Grade 3" mucositis (WHO) was 25.1 days versus 49.2 days with and without amifostine (p = 0.03). In the amifostine group, 11/13 of the patients required a feeding tube (nasogastric tube or medical gastrostomy), because of acute mucositis, whereas in the control group a feeding tube was necessary in all cases. The mean duration of the use of this feeding tube was 1 month versus 2.5 months with and without amifostine respectively (p < 0.01). Local-regional control was not different between both arms with a median follow-up of 15 months.
                Despite the limited number of patients, this pilot randomized study suggests that amifostine was able to markedly reduce the severity and duration of mucositis induced by very accelerated radiotherapy. However, the tolerance of this twice daily amifostine schedule was relatively poor. We wished to determine if filgrastim administration to chemotherapy/radiation therapy-naive patients receiving external-beam irradiation for head-and-neck malignancies would reduce the incidence and severity of oral/oropharyngeal mucositis. Patients were randomized to receive subcutaneous injections of either filgrastim or placebo beginning on day 1 of radiation and continuing daily throughout treatment. Study medication was titrated to keep the neutrophil count between 10 x 10(9) and 30 x 10(9)/l. The left and right buccal mucosa, hard palate, and posterior pharyngeal wall were scored weekly, by a blinded evaluator using two different scales, and the most severe score per week was used in data analysis. Fourteen of a planned 54 patients were randomized (8 filgrastim, 6 placebo), and were evaluable for a planned interim analysis. No statistically significant between-group differences were seen in mean worst scores across time using repeated measures analysis of variance (Hickey, p = 0.231; WHO, p= 0.288). At almost all timepoints, however, the worst mean scores were lower in patients treated with filgrastim compared with those in patients treated with placebo, and the number of severe (i.e., grade 3) mucositis scores was significantly lower in the filgrastim-treated group. Filgrastim may decrease the severity of radiation-induced oral/oropharyngeal mucositis. The aim of this study was to evaluate the effect of pure natural honey on radiation-induced mucositis.
                Forty patients diagnosed with head and neck cancer requiring radiation to the oropharyngeal mucosal area were divided in to two groups to receive either radiation alone or radiation plus topical application of pure natural honey. Patients were treated using a 6-MV linear accelerator at a dose rate of 2 Gy per day five times a week up to a dose of 60-70 Gy. In the study arm, patients were advised to take 20 ml of pure honey 15 min before, 15 min after and 6 h post-radiation therapy. Patients were evaluated every week for the development of radiation mucositis using the Radiation Therapy Oncology Group (RTOG) grading system.
                There was significant reduction in the symptomatic grade 3/4 mucositis among honey-treated patients compared to controls; i.e. 20% versus 75% ( p 0.00058). The compliance of honey-treated group of patients was better than controls. Fifty-five percent of patients treated with topical honey showed no change or a positive gain in body weight compared to 25% in the control arm ( p 0.053), the majority of whom lost weight.
                Topical application of natural honey is a simple and cost-effective treatment in radiation mucositis, which warrants further multi-centre randomised trials to validate our finding. Palifermin, a recombinant human keratinocyte growth factor, was tested for potential benefits on acute graft-versus-host disease (GVHD) and hematopoietic recovery in allogeneic hematopoietic stem cell transplantation (HSCT) recipients. This randomized, double-blind, placebo-controlled, dose-escalation study assessed the safety and tolerability of palifermin (n = 69) as compared with placebo (n = 31) in patients conditioned with cyclophosphamide and fractionated total-body irradiation (Cy/TBI) or busulfan and cyclophosphamide (Bu/Cy) and given methotrexate along with a calcineurin inhibitor (cyclosporine A, tacrolimus) for GVHD prophylaxis. All patients received 3 doses before conditioning and either 3 (cohort 1), 6 (cohort 2), or 9 (cohort 3) doses after HSCT. Palifermin doses were 40 mug/kg per day (cohort 1 only) or 60 mug/kg per day (all cohorts). Six patients (placebo = 2, palifermin = 4) experienced a total of 11 dose-limiting toxicities (most often skin, respiratory, or oral mucositis). The most common adverse events included edema, infection, skin pain, or rash. Times to neutrophil and platelet engraftment were similar. No significant differences in acute GVHD incidence or severity, survival, or day 100 relapse rates were observed between groups. Palifermin was associated with reduced incidence and mean severity of mucositis in patients conditioned with Cy/TBI but not Bu/Cy. We conclude that palifermin was generally safe in allogeneic HSCTs but had no significant effect on engraftment, acute GVHD, or survival in this trial. Based on our demonstration of a circadian rhythm in the human oral mucosa cell cycle, with most cells in the G(1) phase in the morning and M phase at night, we hypothesized that morning radiotherapy (RT) would lead to less oral mucositis than afternoon RT.
                A total of 216 patients were randomized to morning (8-10 AM) vs. afternoon (4-6 PM) RT and stratified by radiation dose, smoking status, and center. Patients receiving primary or postoperative RT alone were eligible. Oral mucositis was scored using the Radiation Therapy Oncology Group (RTOG) criteria and a validated scoring system.
                Of 205 evaluable patients, 52.9% vs. 62.4% developed RTOG Grade 3 or greater mucositis after morning vs. afternoon RT, respectively (p = 0.17). Morning RT was also associated with significantly less weight loss after 5 months (p = 0.024). In a subgroup of 111 patients treated to a dose of 66-70 Gy in 33-35 fractions, exploratory analyses revealed a significant reduction in Grade 3 or greater mucositis with morning RT (44.6% vs. 67.3%, p = 0.022) and a longer interval to the development of Grade 3 or greater mucositis (median, >7.9 vs. 5.6 weeks, p = 0.033). In 53 patients, who smoked during therapy, a significant reduction was found in Grade 3 or greater mucositis with morning RT (42.9% vs. 76%, p = 0.025).
                In this proof of principle study, morning RT was associated with significantly less weight loss after 5 months and an apparent reduction in oral mucositis in a subset of patients receiving >/=66 Gy and in patients who smoked during therapy. To determine whether zinc supplementation can accelerate the healing of mucositis and dermatitis after radiotherapy.
                In this double-blind study, patients were placed into two randomized groups (experimental and control) of 50 patients each. The groups were homogeneous with respect to medical history, tumor characteristics, and therapeutic details. The experimental group received a standard dose of a zinc supplement, and the control group was given a placebo.
                Patients in the control group developed Grade 2 mucositis and dermatitis earlier and sooner than patients in the experimental group. There was also a significant difference in the development of Grade 3 mucositis and dermatitis between the two groups. Patients in the experimental group were found to have milder mucositis and dermatitis. Zinc supplementation did not show much benefit in those patients receiving concurrent chemotherapy or make a substantial impact on weight changes.
                Zinc supplementation used in conjunction with radiotherapy could postpone the development of severe mucositis and dermatitis for patients with cancers of the head and neck. Zinc supplementation can also alleviate the degree of mucositis and dermatitis. The impact of zinc on tumor growth and patient survival is under further investigation. The aim of this study was to see if antibiotic pastilles could reduce radiation mucositis, pain, dysphagia and weight loss in patients undergoing radical radiotherapy for head and neck cancer. A total of 275 patients with T1-T4 tumours entered the study; 136 were allocated to suck four times daily a pastille containing amphotericin, polymyxin and tobramycin. The remaining 139 patients received an identical placebo. In all, 54 patients were unevaluable (24 active, 30 placebo). Bacteriological monitoring was carried out before and twice weekly during treatment. Both arms of the study were well balanced for T and N stage, age, sex and radiation dose (60 Gy). There was a slight imbalance in the site of disease which had no substantive effect on the results. The primary study end point was the percentage of patients who developed intermediate or thick pseudomembranes. No statistically significant difference was found in this end point, with 36% of patients in the active arm developing this type of membrane compared with 48% in the placebo arm (P = 0.118). The estimated odds ratio (placebo/active) of developing an intermediate or thick pseudomembrane was 1.59 (95% CI 0.89-2.82). However a more sensitive test comparing the worst recorded mucositis grade between the two arms was statistically significant (P = 0.009). This indicated that the active pastilles had a beneficial effect, but the magnitude was probably smaller than the trial was designed to detect. There was a reduction in mucositis distribution (P = 0.002), mucositis area (P = 0.028), dysphagia (P = 0.006) and weight loss (P = 0.009) in the active arm. There was a clear tendency for patients with positive cultures for aerobic Gram-negative bacteria (AGNB) (P = 0.003) and yeasts (P = 0.026) during treatment to have more severe mucositis. The active pastilles reduced the percentage of patients with yeast cultures (P = 0.003) but had less effect on AGNB. The benefit derived from the pastilles should materially increase patient tolerance to radical radiotherapy for head and neck cancer. The aim of this study was to evaluate the safety, tolerability and efficacy of a topical gel containing histamine dihydrochloride (HDC) versus a placebo gel in preventing oral mucositis in hematopoietic stem cell transplantation (HSCT) patients. A total of 45 patients post-HSCT were enrolled in a prospective longitudinal, placebo-controlled, double-blind study. Patients were evaluated twice weekly for oral mucositis (OMAS, NCI score), oral pain (VAS), oral function and salivary flow rate. Compliance was assessed using a patient diary. Oral mucositis developed in 85% of the HDC group and 63% of the placebo group. The mean maximal intensity for NCI score was 1.45+/-1 in the HDC group and 1.21+/-1.27 in the placebo group (P=0.37). The mean duration of oral mucositis was 4.7+/-3.6 and 2.33+/-2.23 days in the HDC and placebo groups, respectively (P=0.06). The same trends were measured with OMAS. Visual analogue scale for oral pain and oral function was not significantly different between the two groups. Histamine dihydrochloride was found to be safe. In the search for topical agents for the prevention of mucositis, we found that HDC neither improves nor worsens oral mucositis in HSCT patients. The balance between the pro- and anti-inflammatory effects of HDC should be investigated further in order to acquire a clinically effective topical medication based on its anti-inflammatory properties. Despite modern treatment programs, less than 20% of adult cases of acute lymphoblastic leukemia (ALL) are cured. For relapsing and/or refractory patients, use of high dose cytosine arabinoside (ara-C) and anthracyclin achieved a complete remission (CR) rate of up to a 75%. The aim of this study was to evaluate in adult patients with ALL 1) the CR rate of a chemotherapy schedule similar to a schedule for acute myeloblastic leukemia (AML) patients, 2) the antileukemic value and the tolerance of 3 intensive stage treatments, and 3) the impact of recombinant granulocyte-macrophage-colony stimulating factor (rGM-CSF) on chemotherapy-induced neutropenia and infectious complications, as well as the effect of dose intensity.
                Between November 1990 and April 1992, 67 patients ages 15-55 years with de novo ALL were randomly assigned to receive either rGM-CSF or placebo. The induction treatment consisted of idarubicin, methylprednisolone, and high dose ara-C. After achieving CR, patients up to age 45 years who had an HLA-identical sibling were assigned to undergo allogeneic bone marrow transplantation (BMT). All remaining patients received a first course of early intensification with high dose ara-C, mitoxantrone, etoposide, and methylprednisolone, followed by autologous, unpurged BMT.
                Of the 64 eligible patients, 50 (78%) achieved CR. Sixteen allogeneic and 18 autologous BMTs were performed. The median survival was 10.2 months. The 4-year survival was 24%. rGM-CSF only improved the incidence of severe mucositis during the induction course (P = 0.003) and probably also improved the median duration of fever (P = 0.07).
                This schedule, similar to that for the treatment of AML patients, with early BMT included, did not prove to be a satisfactory approach to the treatment of most adult ALL patients, although CR was achieved in 78% of cases. In this study, no major improvement was obtained with rGM-CSF therapy.
                Copyright 1999 American Cancer Society. Mucositis is an acute inflammation of the oral mucosa because of radiotherapy and/or chemotherapy. All patients receiving radiotherapy in the head and neck region develop oral mucositis. The aim of this study was to analyse the effects of selective oral flora elimination on radiotherapy-induced oral mucositis, in a double-blind, randomised, placebo-controlled trial. Sixty-five patients with a malignant tumour in the head and neck regions to be treated with primary curative or postoperative radiotherapy participated in this study. The patients received either the active lozenges of 1 g containing polymyxin E 2 mg, tobramycin 1.8 mg and amphotericin B 10 mg (PTA) (33 patients) or the placebo lozenges (32 patients), four times daily during the full course of radiotherapy. Mucositis, changes in the oral flora, quality of feeding and changes of total body weight were assessed. Mucositis score did not differ between the groups during the first 5 weeks of radiotherapy. Nasogastric tube feeding was needed in six patients (19%) of the placebo group and two patients (6%) of the PTA group (P=0.08). Mean weight loss after 5 weeks of radiation was less in the PTA group (1.3 kg) (s.d.: 3.0) than in the placebo group (2.8 kg) (s.d.: 2.9) (P=0.05). Colonisation index of Candida species and Gram-negative bacilli was reduced in the PTA group and not in the placebo group (P<0.05). No effect on other microorganisms was detected. In conclusion, selective oral flora elimination in head and neck irradiation patients does not prevent the development of severe mucositis. Recently, a randomised study demonstrated the utility of oral cooling (cryotherapy) in the prevention of 5-fluorouracil (5FU)-induced stomatitis. In order to verify these results a confirmatory study, using identical treatment regimen, was initiated. 84 patients treated with a 5-FU-containing regimen were randomised to a control arm or to receive oral cryotherapy. End point evaluation was obtained by a global assessment of the physician's judgement and patients' description of mucositis severity graded 0-4. Mucositis was significantly reduced by cryotherapy considering both the first cycle of therapy (the mean toxicity score for cryotherapy was 0.59 and it was 1.1 for the control group, P < or = 0.05) and all the chemotherapeutic courses (the mean toxicity score for cryotherapy was 0.36 when it was 0.69 for the control group, P < or = 0.05). In conclusion, the present study confirms that cryotherapy can decrease 5FU-induced stomatitis and should be recommended for patients receiving bolus 5FU-containing regimens. To evaluate prospectively the efficacy of granulocyte-macrophage colony-stimulating factor (GM-CSF) in the reduction of chemotherapy-induced oral mucositis.
                Twenty patients with stage IV squamous cell carcinoma of head and neck were studied. Two-cycles (periods) of identical doses of cisplatin, fluorouracil (5-FU), and leucovorin (PFL) chemotherapy with cisplatin 20 mg/m2/d, 5-FU 800 mg/m2/d, leucovorin 90 mg/m2/d by 96-hour continuous intravenous infusion every 3 weeks were given to each patient. After PFL chemotherapy, GM-CSF 4 micrograms/kg subcutaneously from days 5 to 14 or no therapy was given by a randomized self-controlled crossover study design. Oral mucositis was graded with modified Radiation Therapy Oncology Group criteria.
                In the first cycle of PFL chemotherapy, GM-CSF significantly reduced the incidence, mean duration, and mean area under the curve (AUC) of severe oral gross mucositis (grade > or = 3) compared with no therapy. These beneficial effects continued into the second cycle of PFL chemotherapy after crossover to no GM-CSF. The incidence of severe mucositis was reduced when GM-CSF was given in the second cycle of PFL. Analysis of variance indicated significant direct GM-CSF treatment effects on the mean AUC of gross/functional scores and duration of moderate gross mucositis (grade > or = 2) over both periods. There was a significant period effect in favor of giving GM-CSF in the first cycle of chemotherapy.
                GM-CSF can significantly reduce the severity and duration of chemotherapy-induced oral mucositis after PFL chemotherapy. Acute mucositis is dose-limiting in many accelerated radiotherapy schedules for head and neck cancer. Cytokines may be one means of reducing the severity of mucositis. A study was designed to assess the effect of subcutaneous molgramostin (granulocyte-macrophage colony stimulating factor; GM-CSF) injections on acute radiation morbidity in patients undergoing accelerated radiotherapy for laryngeal cancer. A prospective, randomized, observer-blind, controlled trial was conducted in 29 patients who were to receive radical radiotherapy over 3 weeks for early stage laryngeal cancer. Patients were randomized to receive 150 microg (approximately 2 microg kg(-1)) GM-CSF subcutaneously once daily for 14 days after the second week of radiotherapy, or no GM-CSF. Patients were assessed weekly for grade of mucositis, skin reactions and related parameters. The severity of mucositis was reduced in the GM-CSF arm (p<0.05). No other end-points reached statistical significance. Two patients failed to complete their courses of GM-CSF. Three developed influenza type symptoms and in one an allergic reaction was noted. There was no difference in tumour control rates. Subcutaneous GM-CSF reduced the severity of mucositis in patients undergoing accelerated radiotherapy. Injections were well tolerated. Further studies of cytokines are warranted, to assess the feasibility of increasing the total doses of accelerated radiotherapy given, with the aim of improving tumour cure rates. Pursuant to a promising report suggesting that an allopurinol mouthwash could have a protective effect against 5-fluorouracil (5-FU)-induced stomatitis, the authors performed a randomized, placebo-controlled, double-blind, crossover study. Seventy-seven patients, receiving their first 5-day course of chemotherapy with 5-FU +/- leucovorin, were assigned to use a mouthwash containing 20 mg of allopurinol or a placebo. The mouthwash was administered every hour for four doses commencing with each chemotherapy dose. The severity of subsequent mucositis was graded (on a 0-4 scale) by the attending physician and also by a patient-completed questionnaire. There was trend toward less mucositis in the placebo group with mean physician-judged mucositis scores of 1.3 for placebo and 1.8 for allopurinol (P = 0.07) and mean patient-judged mucositis scores of 1.5 for placebo and 1.9 for allopurinol (P = 0.15). There were no substantial differences in mucositis attributable to the two mouthwashes in the patients who crossed-over on their second cycle of chemotherapy. These data demonstrate that the tested allopurinol mouthwash regimen does not offer any protective effect against 5-FU-induced mucositis. Systemic chemotherapy may damage gastrointestinal epithelium. Mucositis is associated with increased intestinal permeability (IP). It is known that IP test with chromium 51-ethylene diaminetetra-acetate (51Cr-EDTA) is a useful tool to assess the mucositis. Oral glutamine supplements (OGS) may have a role in the prevention of chemotherapy-induced mucositis/stomatitis. The aim of this study was to characterize the relationship between the urinary excretion of 51Cr-EDTA and the severity of mucositis, and the effect of OGS on 5-fluorouracil/leucovorin (FU/LV)-induced mucositis/stomatitis.
                Fifty-one patients with advanced or metastatic cancer received FU/LV chemotherapy. The control group included 18 healthy volunteers. IP was assessed via the measurement of 51Cr-EDTA urinary excretion after oral challenge, on days 7 after the discontinuation of chemotherapy. Of the 51 patients, 22 patients received OGS (30 g/day) and 29 received only best supportive care (BSC). Glutamine supplementation continued for 15 days. It was initiated at least 3 days before the beginning of chemotherapy. Mucositis/stomatitis was graded according to version 3.0 of the Common Terminology Criteria for Adverse Events.
                In the chemotherapy group, the median (25 percentile, 75 percentile) IP test score was significantly higher than those of the control group [6.78% (4.63, 10.66) vs. 2.17% (1.38, 2.40), P<0.001]. The severity of stomatitis was significantly correlated with IP test scores (r=0.898, P<0.001). In the OGS group, the median IP test score was significantly lower than that of the BSC group [4.69% (3.10, 6.48) vs. 8.54% (6.48, 15.31), P<0.001]. A mucositis/stomatitis of grade 2-4 was observed in two patients of the OGS group (9%), and in 11 patients (38%) in the BSC group (P<0.001).
                The IP test may be a useful tool in the evaluation of mucositis/stomatitis. OGS may exert a protective effect on FU/LV-induced mucositis/stomatitis. Further studies, however, will be necessary to define the role of glutamine supplementation in FU/LV-induced mucositis/stomatitis. Acute mucositis is a dose-limiting toxicity of concurrent chemoradiotherapy regimens for locally advanced head and neck cancer. Palifermin (a recombinant human keratinocyte growth factor; DeltaN23-KGF) stimulates the proliferation and differentiation of mucosal epithelium to reduce mucositis in patients receiving intensive therapy for hematologic cancers. This study assessed the efficacy and safety of palifermin in patients receiving concurrent chemoradiotherapy for advanced head and neck squamous cell carcinoma.
                In a phase II trial, standard radiotherapy was delivered in daily 2-Gy fractions to 70 Gy, or hyperfractionated radiotherapy was delivered in 1.25-Gy fractions twice daily to 72 Gy, over 7 weeks. Chemotherapy included cisplatin 20 mg/m(2) for 4 days and continuous-infusion fluorouracil 1,000 mg/m(2)/d for 4 days on weeks 1 and 5 of irradiation. Patients were randomly assigned 2:1 to palifermin 60 microg/kg or placebo once weekly for 10 doses. A follow-up trial evaluated long-term survival.
                Sixty-seven patients received palifermin and 32 received placebo. The median duration of grade >or= 2 mucositis was 6.5 and 8.1 weeks in the palifermin and placebo groups, respectively (P = .157). Palifermin appeared to reduce mucositis, dysphagia, and xerostomia during hyperfractionated radiotherapy (n = 40) but not standard radiation therapy (n = 59). Adverse events were similar between treatment groups. Palifermin did not alter tumor response or survival.
                Ten once-weekly doses of palifermin at 60 microg/kg were well tolerated. Most patients completed treatment, but palifermin did not reduce the morbidity of concurrent chemotherapy and radiotherapy. Future studies should evaluate higher palifermin doses with longer and more standardized assessment of acute mucositis. To evaluate the safety of recombinant human keratinocyte growth factor (KGF) when administered with fluorouracil (FU) in patients with metastatic colorectal cancer.
                Patients (N = 81) received KGF by intravenous (IV) bolus on days 1 to 3, followed by FU 425 mg/m2/d IV bolus plus leucovorin 20 mg/m2/d IV on days 4 to 8. KGF dose levels were 1, 10, 20, 40, 60, and 80 microg/kg/d. A randomized, placebo-controlled design was employed (2:1 randomization of KGF to placebo). Oral mucositis was assessed by examination on days 1, 4, 8, 15, and 28. In addition, patients provided daily assessments of oral symptoms using a self-administered questionnaire.
                Skin and oral events occurred in 13 of 18 patients (eight patients, grade 1; four patients, grade 2; and one patient, grade 3) treated with 60 and 80 microg/kg of KGF and three of 11 patients treated with 40 microg/kg (grade 1). These symptoms were dose limiting in three cases (ie, in two of 10 patients treated with 80 microg/kg and in one of eight patients treated with 60 microg/kg). The frequency of grade 2 to 4 mucositis was 43% in patients treated with KGF, compared with 67% in patients treated with placebo (P =.06). Patient self-assessments of oral pain and clinical assessments of mucositis showed good correlation (Kendall's tau = 0.75).
                KGF is generally well tolerated when administered IV at doses up to 40 microg/kg/d for 3 days before a 5-day course of FU plus leucovorin. A clinically meaningful biologic effect was also suggested in that patients treated with the epithelial growth factor KGF had a lower rate of grade 2 to 4 mucositis than did patients treated with placebo. Radiotherapy for head and neck cancer causes acute and chronic xerostomia and acute mucositis. Amifositine and its active metabolite, WR-1065, accumulate with high concentrations in the salivary glands. This randomized trial evaluated whether amifostine could ameliorate these side effects without compromising the effectiveness of radiotherapy in these patients.
                Patients with previously untreated head and neck squamous cell carcinoma were eligible. Primary end points included the incidence of grade > or =2 acute xerostomia, grade > or =3 acute mucositis, and grade > or =2 late xerostomia and were based on the worst toxicity reported. Amifostine was administered (200 mg/m(2) intravenous) daily 15 to 30 minutes before irradiation. Radiotherapy was given once daily (1.8 to 2.0 Gy) to doses of 50 to 70 Gy. Whole saliva production was quantitated preradiotherapy and regularly during follow-up. Patients evaluated their symptoms through a questionnaire during and after treatment. Local-regional control was the primary antitumor efficacy end point.
                Nausea, vomiting, hypotension, and allergic reactions were the most common side effects. Fifty-three percent of the patients receiving amifostine had at least one episode of nausea and/or vomiting, but it only occurred with 233 (5%) of 4,314 doses. Amifostine reduced grade > or =2 acute xerostomia from 78% to 51% (P<.0001) and chronic xerostomia grade > or = 2 from 57% to 34% (P=.002). Median saliva production was greater with amifostine (0.26 g v 0.10 g, P=.04). Amifostine did not reduce mucositis. With and without amifostine, 2-year local-regional control, disease-free survival, and overall survival were 58% versus 63%, 53% versus 57%, and 71% versus 66%, respectively.
                Amifostine reduced acute and chronic xerostomia. Antitumor treatment efficacy was preserved. The aim of this study was to evaluate the effectiveness of granulocyte-macrophage colony-stimulating factor (GM-CSF) mouthwashes in the prevention of severe mucositis induced by high doses of chemotherapy.
                Ninety consecutive patients affected by solid tumors and undergoing high-dose chemotherapy with autologous peripheral blood stem cell transplantation rescue were randomized to receive placebo versus GM-CSF mouthwash 150 micro g/day. Patients were stratified on the basis of the conditioning treatment and the consequent different risk of severe oral mucositis. Treatment was administered from the day after the end of chemotherapy until the resolution of stomatitis and/or neutrophil recovery.
                The statistical analyses were intention-to-treat and involved all patients who entered the study. The severity of stomatitis was evaluated daily by the physicians according to National Cancer Institute Common Toxicity Criteria. Both study and control groups were compared with respect to the frequency [30% versus 36%, chi(2) exact test, not significant (NS)] and mean duration (4.8 +/- 4.7 versus 4.4 +/- 2.7 days, t-test, NS) of severe stomatitis (grade > or =3). Oral pain was evaluated daily by patients themselves by means of a 10 cm analog visual scale: the mean (+/- standard error of the mean) maximum mucositis scores were 4.8 +/- 3.5 versus 4.2 +/- 3.5 cm (t-test, NS). Furthermore, 15/46 patients in the study group (33%) and 19/44 patients in the control group experienced pain requiring opioids (chi(2) exact test, NS).
                We did not find any evidence to indicate that prophylaxis with GM-CSF mouthwash can help to reduce the severity of mucositis in the setting of the patients we studied. The authors previously reported that 30 minutes of oral cryotherapy inhibits 5-fluorouracil (5-FU)-induced stomatitis. The current trial was designed to determine whether a longer duration of cryotherapy would provide additional protection.
                This trial involved patients who were receiving their first course of a 5-FU plus leucovorin chemotherapy regimen, for which stomatitis is a major dose-limiting toxicity. These patients were randomized to receive either 30 or 60 minutes of oral cryotherapy given at around the same time as the 5-FU therapy.
                A total of 178 evaluable patients were studied. Both cryotherapy groups had similar degrees of mucositis.
                The authors continue to recommend the use of 30 minutes of oral cryotherapy for patients receiving bolus intensive courses of 5-FU-based chemotherapy. Between October 1988 and December 1990, 60 patients with leukaemia (25 with AML, 19 ALL and 16 CML) undergoing BMT were randomised in a double-blind clinical trial to receive prostaglandin E2 (PGE) (Prostin E2, 0.5 mg per tablet) or placebo for prophylaxis of oral mucositis. Patients had to dissolve tablets in the mouth three times daily starting 7 days before BMT and continuing until 21 days after BMT. The incidence of severe oral mucositis was similar for both groups, 55% in patients receiving PGE and 52% in patients receiving placebo. The duration of severe mucositis did not differ between PGE and placebo groups (chi-square 0.95, p = NS). The incidence of HSV infection was significantly higher in patients receiving PGE. Patients with HSV infection receiving PGE also had a higher incidence of severe oral mucositis. The results presented indicate that PGE is not effective for prophylaxis of oral mucositis in BMT recipients. The mucosal protective effect of sucralfate (Ulcogant) was evaluated in a prospective randomised clinical study during radiation therapy. Twenty-four patients received 1 g of a sucralfate suspension 4 times a day orally for 5 min each. This group was compared with a control group of 21 patients receiving standard oral hygiene consisting of frequent tooth cleaning and disinfection of the oral and pharyngeal mucosa. The radiation technique was telecobalt therapy in two opposing fields using the shrinking field technique, with an electron boost to the posterior lymph nodes; the dosage was 60-70 Gy in daily fractions of 2 Gy. Mucosal reactions, pain and difficulty in swallowing were recorded twice a week. We also checked the patient's weight during treatment. The patients showed significant differences in all parameters, and lower weight loss compared with the control group. Minimal or absent mucosal inflammation pain or dysphagia were found in 88%, 79% and 83% respectively, while 43% and 29% and 52% of the controls had such mild radiation side-effects. Local effectivity appeared to be less in the hypopharynx due to shorter time of application compared with mouth and oropharynx. There were no side-effects from the sucralfate. Sucralfate prophylaxis is effective and easy to apply in the protection of mucosa during irradiation therapy. Mucositis is a prominent dose-limiting toxicity associated with 5-FU-based chemotherapy. On the basis of preliminary data suggesting that the amino acid glutamine could alleviate this problem, the authors developed this trial. Patients scheduled to receive their first 5-FU-based chemotherapy regimen were selected for study. Following stratification, patients were randomized, in a double-blind manner, to receive oral glutamine or a placebo preparation in a prophylactic manner. Patients in both groups were given oral cryotherapy before chemotherapy and were evaluated for mucositis by standard physicians' evaluation and by a self-report instrument. Sixty-six patients were randomized to receive glutamine and 68 to receive the placebo preparation. There were no significant differences or substantial trends in the mucositis scores between the two study arms as measured by either the physicians or the patients. It was concluded that the dose and schedule of glutamine used in this clinical trial does not alleviate 5-FU-induced mucositis. In this study, the ability of granulocyte colony-stimulating factor (G-CSF) to treat or prevent chemotherapy-induced oral mucositis in patients with advanced breast cancer was evaluated. A total of 14 patients who received intraarterial (i.a.) adriamycin (ADM) preoperatively were divided into two groups according to whether or not G-CSF was given. Thus, group A (n = 7) was given G-CSF and group B (n = 7) was not. G-CSF therapy reduced both the incidence and duration of ADM-induced oral mucositis, and a positive correlation was also seen between the incidence of mucositis and ADM-induced leukopenia (< 2,000/mm3). Group A was further divided into two subgroups according to whether G-CSF was given after or before the leukopenia had dropped below 2,000/mm3: group A-1 (n = 3) and group A-2 (n = 4), respectively. ADM-induced mucositis was observed in two of the three patients in group A-1, but in none of the four patients in group A-2. These results strongly support the idea that G-CSF can effectively treat and prevent ADM-induced oral mucositis. In some clinical situations the endogenous production of glutamine may be insufficient to maintain optimal tissue structure and function such that glutamine becomes a conditionally essential amino acid. Studies in laboratory animals have demonstrated that glutamine supplementation can reduce the incidence and severity of cytotoxic-induced mucositis. This study examined the role of oral glutamine supplementation in the management of mucositis caused by 5-fluorouracil (5-FU) and folinic acid. Twenty-eight patients with gastrointestinal cancers were randomised to receive 16 g of glutamine per day for 8 days, or placebo, in a randomised double-blind trial before crossing over to the alternative supplement during the second treatment cycle. The supplement was well tolerated with no apparent adverse effects, but failed to have any significant effect on oral mucositis assessed by the patients or investigator. The possible reasons for this apparent lack of benefit are discussed. This study evaluated the safety and efficacy of recombinant human intestinal trefoil factor (rhITF) administered as topical oral spray for prevention and treatment of chemotherapy-induced oral mucositis (OM).
                Ninety-nine patients with colorectal cancer who had moderate to severe OM (WHO grade >or= 2) in the first cycle of chemotherapy were randomly assigned to receive either placebo, rhITF 10 mg/mL (ie, low dose), or rhITF 80 mg/mL (ie, high dose) by oral spray (300 microL, eight times each day) for 14 consecutive days in the second chemotherapy cycle. Patients were assessed on days 1, 3, 5, 7, 10, 12, 14, and 21 (+/- 2 days for the last assessment) for safety and for OM incidence and severity.
                Treatment of patients at high risk for developing OM with low- or high-dose rhITF significantly reduced the amount of incidence (75% to 81%; low-dose rhITF P < .001; high-dose rhITF P = .002). Frequencies of WHO grade >or= 2 OM in the placebo, low-dose rhITF, and high-dose rhITF groups were 48.5%, 9.1%, and 12.1%, respectively. Assessment of the area under the curve revealed statistically significant reductions in OM severity in the rhITF-treated groups versus placebo. Only a minority of patients (6.1%) reported treatment-emergent adverse events (TEAEs), all of which were mild to moderate in intensity and resolved without sequelae. The incidence of TEAEs was not significantly different among treatment groups.
                rhITF oral spray formulation was safe and effective when used for the reduction of chemotherapy-associated OM in patients with colorectal cancer. Patients exhibited high compliance in dosing administration. Future clinical study is planned to develop this drug for use in OM management in patients with cancer. Amifostine has a potential role for salivary gland protection in head and neck cancer patients who had radiotherapy.
                Sixty-seven head and neck cancer patients were randomized to receive radiotherapy or radiotherapy plus Amifostine. The efficacy of the treatment was determined by a questionnaire evaluating dryness of mouth and the oral comfort, the RTOG/EORTC acute/late radiation morbidity scoring criteria, collection of the whole saliva and the 99mTc-pertecnetate scintigraphy of the salivary glands.
                Amifostine significantly reduced the mean questionnaire scores from 6.49 to 3.73, the incidence of grade > or = 2 mucositis from 75% to 36% and acute xerostomia from 82% to 39%. The salivary gland function returned to normal at a rate of 36.3% in the Amifostine group versus 9.1% in the control group.
                Amifostine is effective in reducing the incidence and severity of acute mucositis, acute and late xerostomia in head and neck cancer patients. Oral mucositis is a common debilitating complication of radiotherapy occurring in about 60 per cent of cancer patients. Considerable buccal toxicity of radiotherapy or chemotherapy in cancer patients to become discouraged and can affect their quality of life. In addition, such toxicity can alter the treatment plan. At present, there is no clinically appropriate prophylaxis efficacious antidote for mucositis. The low level laser (LEL) appears to be a simple, non-traumatic technique for the prevention and treatment of radiation induced mucositis. Therefore the present study was carried out to find out the effect of low-level helium-neon (He-Ne) laser in the prevention and treatment of radiation induced mucositis in head and neck cancer patients.
                The patients with carcinoma of oral cavity with stages II-IV a being uniformly treated with curative total tumour dose of 66 Gy in 33 fractions over 6 wk were selected for the study. The patients were divided based on computer generated randamosization into laser (study group) and control groups with 25 patients in each group. Both study and control groups were comparable in terms of site of the lesion, stage of the cancer and histology. The study group patients were treated with He-Ne laser (wavelength 632.8 nm and output of 10mW) and control group patients were given oral analgesics, local application of anaesthetics, 0.9 per cent saline and povidine wash during the course of radiotherapy.
                All patients tolerated the laser treatment without any adverse effect or reactions. The result showed a significant difference in pain and mucositis (P<0.001) between the two groups. At the end of radiotherapy (after 6 wk) mean pain sure and mucositis grade were significantly lower (P<0.001) in the study group compared to control.
                The low-level He-Ne laser therapy during the radiotherapy treatment was found to be effective in preventing and treating the mucositis in head and neck cancer patients. Further studies need to be done on a larger sample to find the mechanism. Oral mucositis is frequent but serious adverse event associated with radiotherapy or radiochemotherapy in head and neck cancer severely impairs health-related quality of life, leading to poor prognosis due to discontinuation of the therapy. Although a number of compounds have been tested for prophylaxis of oral mucositis, few of them are satisfactory. We investigated the effect of polaprezinc (zinc L-carnosine), a gastric mucosal protective drug, on radiochemotherapy-induced oral mucositis, pain, xerostomia and taste disturbance in patients with head and neck cancer. Patients were randomly assigned to receive polaprezinc (n = 16) or azulene oral rinse as the control (n = 15). The incidence rates of mucositis, pain, xerostomia and taste disturbance were all markedly lower in polaprezinc group than in control. Moreover, the use of analgesics was significantly (p = 0.003) less frequent and the amount of food intake was significantly (p = 0.002) higher in polaprezinc group than in control. On the other hand, tumor response rate in patients with neoadjuvant radiochemotherapy was not significantly affected by polaprezinc, in which the response rate (complete plus partial response) was 88% for polaprezinc and 92% for control (p = 1.000). Therefore, it is highly assumable that polaprezinc is potentially useful for prevention of oral mucositis and improvement of quality of life without reducing the tumor response. Based on in vitro and on clinical evidence of protection against acute side effects of radiation, a prospective randomized, open study was performed to determine the efficacy of an oral proteolytic enzyme preparation in patients with head and neck cancer receiving conventional fractionated radiation therapy.
                Patients with stage T3/T4 head and neck cancer were eligible. One hundred patients from two centres were entered into the study. 60Co gamma-radiation was delivered at a standard daily radiation dose of 2 Gy in 25-35 fractions over a period of 6-7 weeks. Two lateral parallel opposing fields were used with a portal area of 10 x 15 cm. Patients assigned to the test group arm additionally received enzyme tablets orally t.i.d. starting 3 days prior to radiation therapy, and continuing up to 5 days after completion of the course of radiation therapy. Patients in the control arm were not given any drug or placebo. Acute radiation side effects were described as mucositis, skin reaction, dysphagia, and were graded at each visit during and after radiation therapy, following RTOG/EORTC criteria.
                The severity (maximum extent) of acute radiation therapy side effects was significantly less in enzyme-treated patients than in control patients: mucositis (mean: 1.3 vs 2.2, P < 0.001), skin reaction (1.2 vs 2.4, P < 0.001) and dysphagia (1.4 vs 2.2, P < 0.001). The duration of these side effects as well as the sum scores of side effects were also less in the study arm.
                Combination of enzyme therapy with conventional fractionated radiation therapy was feasible and well-tolerated. There was significant protection against acute side effects of radiation therapy in the study arm. Not only was the severity of acute side effects less but the duration was shorter and the time to onset was also delayed. Prospective randomized double-blind studies would verify this role of an oral enzyme therapy as standard co-medication with radiation therapy to the head and neck region. To evaluate the safety of repifermin (keratinocyte growth factor-2) administered before and after autologous hematopoietic stem cell transplantation (auto-HSCT). A preliminary analysis of the ability of keratinocyte growth factor-2 to prevent mucositis was also done.
                Forty-two patients received intravenous repifermin (25 microg/kg or 50 microg/kg) or placebo for 3 days before their auto-HSCT conditioning regimen and for up to 10 days after auto-HSCT. Within each dose level, 14 patients were randomized to repifermin and 7 patients to placebo. Clinical evaluations of mucositis were scheduled before auto-HSCT conditioning regimen, on the day of transplant, and three times per week until mucositis resolved.
                In general, the incidence of adverse events was similar for patients treated with repifermin and placebo. No clinically meaningful differences were noted among treatment groups for clinical laboratory variables. Treatment groups experienced similar time to engraftment. The frequency of Grade 2 to 4 mucositis was 100% for patients in the placebo group, 64% for patients in the 25 microg/kg group (P = 0.041 versus placebo), and 50% for patients in the 50 microg/kg group (P = 0.006 versus placebo). Results of other endpoints, including pain on swallowing and use of pain medication specifically for mucositis, suggested a better outcome for patients in the 50 microg/kg group compared with the placebo and 25 microg/kg groups.
                Repifermin was well tolerated. Repifermin given before and after auto-HSCT seems to be active in reducing mucositis, but a larger trial will be necessary to determine the efficacy of repifermin with this dose schedule. A randomized study was conducted to evaluate the protective activity of amifostine (A) against the dose-limiting toxicities of radiochemotherapy (RCT). Patients with head and neck cancer received radiotherapy (2 Gy/day 5 days a week up to 60 Gy) with carboplatin 70 mg/m2 on days 1-5 and 21-25 inclusive. Patients either received RCT alone (n = 14) or RCT + A at a dose of 500 mg prior to treatment with carboplatin (n = 25). There was a significant reduction in the incidence of grade 3/4 mucositis (P < 0.0001), acute grade 2 xerostomia (P < 0.0001) and grade 3/4 thrombocytopenia (P = 0.012) in these patients who received A. The incidence of grade 2 late xerostomia at 12 months is 16.7% and the incidence of loss of taste is 0% in patients treated with A, as opposed to 54.5% and 63.6% in patients who received RCT alone. There were 18 (72%) complete responses (CR) and 6 (24%) partial responses (PR) in patients who received A, compared with 6 (43%) CR and 6 PR (43%) in patients treated with RCT alone. The disease-free survival at 12 months is 85.7% in the RCT + A arm and 78.6% in the RCT alone arm. The use of amifostine reduces the incidence and severity of acute and late toxicities associated with RCT whilst preserving antitumour activity. Several chemotherapeutic regimens and radiation therapy, if delivered to the oral mucosa, are associated with a high frequency of mouth lesions. The cause of this side effect is not known for certain, but in past studies it has sometimes been associated with the ability to culture herpes simplex virus type 1 from the mouth. In a double-blind prospective trial, patients with head and neck tumors treated with chemotherapy or radiation therapy were treated with either acyclovir or placebo. Although the frequency of culture-positive herpes simplex virus was low in the untreated group, it was significantly lower, zero, in the acyclovir-treated group. However, there were no differences in the frequency or type of mouth lesions experienced by patients receiving either radiation or chemotherapy who were taking acyclovir or placebo. These results suggest that herpes simplex virus is not a frequent cause or complication of oral lesions afflicting this patient population. Forty patients with multiple myeloma scheduled to receive melphalan 200 mg/m(2) followed by autologous stem cell transplantation were randomly assigned to receive oral cryotherapy or room temperature normal saline rinses 30 min before and for 6 h after high-dose therapy. Patients were evaluated for the development of mucositis using the National Cancer Institute grading system as well as evaluation of secondary measures such as days of total parenteral nutrition (TPN), narcotic use, hospitalization, weight loss and resumption of oral caloric intake for 28 days after transplant. Patients self-scored their pain, swallowing, drinking, eating, sleeping and taste alterations for 28 days. The primary end point of this trial was the incidence of grades 3-4 mucositis. Compared to the normal saline group, patients using cryotherapy experienced less grade 3-4 mucositis, 14 vs 74%, P=0.0005. Patients receiving cryotherapy also had statistically lower uses of narcotics and TPN, although there were no differences in length of hospitalization or weight loss. Patient-reported pain was significantly lower and activities were significantly better in the cryotherapy group. Amifostine (WR-2721) is an important cytoprotective agent. Although intravenous administration is the standard route, pharmacokinetic studies have shown acceptable plasma levels of the active metabolite of amifostine (WR-1605) after subcutaneous administration. The subcutaneous route, due to its simplicity, presents multiple advantages over the intravenous route when amifostine is used during fractionated radiotherapy.
                Sixty patients with thoracic, 40 with head and neck, and 40 with pelvic tumors who were undergoing radical radiotherapy were enrolled onto a randomized phase II trial to assess the feasibility, tolerance, and cytoprotective efficacy of amifostine administered subcutaneously. A flat dose of amifostine 500 mg, diluted in 2.5 mL of normal saline, was injected subcutaneously 20 minutes before each radiotherapy fraction.
                The subcutaneous amifostine regimen was well tolerated by 85% of patients. In approximately 5% of patients, amifostine therapy was interrupted due to cumulative asthenia, and in 10%, due to a fever/rash reaction. Hypotension was never noted, whereas nausea was frequent. A significant reduction of pharyngeal, esophageal, and rectal mucositis was noted in the amifostine arm (P <.04). The delays in radiotherapy because of grade 3 mucositis were significantly longer in the group of patients treated with radiotherapy alone (P <.04). Amifostine significantly reduced the incidence of acute perineal skin and bladder toxicity (P <.0006).
                Subcutaneous administration of amifostine is well tolerated, effectively reduces radiotherapy's early toxicity, and prevents delays in radiotherapy. The subcutaneous route is much simpler and saves time compared with the intravenous route of administration and can be safely and effectively applied in the daily, busy radiotherapy practice. We evaluated the efficacy of benzydamine oral rinse for prevention of radiation-induced mucositis. Patients with head and neck cancers, who were referred in 2004-2005, received an oral rinse of either benzydamine or placebo. One hundred patients were randomized in this trial. At the end of the study, 19 patients were excluded from the analysis because they did not use the medication for the assigned period. In the benzydamine group, the frequency of mucositis grade > or =3 was 43.6% in contrast to 78.6% in other group (P = 0.001). Grade > or =3 mucositis was 2.6 times more frequent in the placebo group. Intensity of mucositis increased up to fourth week of treatment in both groups to grade 2. In the treated group the grade of mucositis was approximately constant to the end of therapy; but in the control group it raised to grade 3 (P < 0.001). The highest grade of mucositis during the treatment time was significantly different between two groups (P = 0.049). The median interval to observation of grade > or =2 mucositis was 24 days in the placebo group and 28 days in the benzydamine group (P = 0.12). Benzydamine oral rinse seems to be effective, safe, and well tolerated for prophylactic treatment of radiation-induced oral mucositis in head and neck tumours. We performed this double-blinded, placebo-controlled study to determine the safety and efficacy of L-alanyl-L-glutamine in the prevention of mucositis in patients with head-and-neck cancer.
                Thirty-two patients with head-and-neck cancer were treated with chemoradiotherapy (CRT) (radiotherapy daily up to 70 Gy plus cisplatin/5-fluoruracil once a week) and were asked to participate. Twenty-nine patients received the CRT schedule and were double-blindly assigned to receive either intravenous L-alanyl-L-glutamine 0.4 g/kg weight/day or an equal volume of saline (placebo) during chemotherapy days.
                Fourteen patients received L-alanyl-L-glutamine and 15 received placebo. Mucositis was assessed by the Objective Mucositis Score (OMS) and the World Health Organization (WHO) grading system. There was a significant difference in incidence of mucositis developed in patients receiving placebo compared with those who received L-alanyl-L-glutamine (p = 0.035). The number of patients with severe objective mucositis (OMS >1.49) was higher in the placebo group compared with the L-alanyl-L-glutamine group (67% vs. 14%, p = 0.007). L-alanyl-L-glutamine patients experienced less pain (three highest Numeric Rating Scale scores of 1.3/10 vs. 6.3/10 respectively, p = 0.008) and need for feeding tubes (14% vs. 60% respectively, p = 0.020) compared with placebo patients. No adverse effects related to the drug or the infusions were noted in either group.
                For patients with head-and-neck cancer receiving CRT, intravenous L-alanyl-L-glutamine may be an effective preventive measure to decrease the severity of mucositis. Mucositis is a major complication in myeloablative therapy, which often necessitates advanced pharmacological pain treatment, including i.v. opioids. Attempts to prevent oral mucositis have included oral cryotherapy, which has been shown to reduce mucositis, but there is a lack of knowledge concerning the effect of oral cryotherapy on opioid use by reducing the mucositis for patients treated with myeloablative therapy before bone marrow transplantation (BMT).
                The aim of the present study was to evaluate if oral cryotherapy could delay or alleviate the development of mucositis and thereby reduce the number of days with i.v. opioids among patients who receive myeloablative therapy before BMT.
                Eighty patients 18 years and older, scheduled for BMT, were included consecutively and randomised to oral cryotherapy or standard oral care. A stratified randomisation was used with regard to type of transplantation. Intensity of pain, severity of mucositis and use of opioids were recorded using pain visual analogue scale (VAS) scores, mucositis index scores and medical and nursing charts.
                This study showed that patients receiving oral cryotherapy had less pronounced mucositis and significantly fewer days with i.v. opioids than the control group. In the autologous setting, cryotherapy patients also needed significantly lower total dose of opioids.
                Oral cryotherapy is an effective and well-tolerated therapy to alleviate mucositis and consequently reduce the number of days with i.v. opioids among patients treated with myeloablative therapy before BMT. Na sucrose octasulfate (Na SOS) was tested for ability to relieve radiation-induced acute skin and mucosal reactions in patients with head and neck cancer. Sixty patients were included in this prospective, double-blind, randomized study. Skin and mucosal reactions were scored using several variables. No statistically significant difference was found between the results with Na SOS and those with placebo for any of the variables, with the exception of skin desquamation, which showed a significant difference in the placebo group. The most likely explanation for this is that the Na SOS gel itself left behind a flaky layer that was difficult to distinguish from radiation-induced flaking. In conclusion, we cannot recommend Na SOS in the routine management of radiation-induced skin and mucosal reactions. Benzydamine hydrochloride rinse was shown to prevent oral mucositis in radiation therapy. Prevention of mucositis allows reduction in morbidity of one of the therapy limiting complications of radiotherapy for cancer therapy. To prepare and evaluate an allopurinol mouth rinse for prophylaxis of fluorouracil-induced mucositis, 33 patients with malignant disorders, who were going to receive 5-fluorouracil containing chemotherapy, were enrolled in a placebo-controlled double-blinded randomized clinical trial. Allopurinol mouthwash (1 mg/ml) or placebo was administered 1, 2 and 3 h after chemotherapy and three consecutive nights. A questionnaire consisting of demographic parameters, medical status, quality of life survey and mucosal injury scoring table (based on World Health Organization scales for mucositis) was completed for each patient at Day 1, 3 and 7 after chemotherapy. In allopurinol group nine participants (60.0%) were female and in placebo group, 10 (66.7%) (P = 0.705). Mean ages were 56.9 +/- 10.3 and 49.5 +/- 13.8 years in allopurinol and placebo groups respectively (P = 0.107). The analysis showed that the higher education level and the use of dentures significantly reduced the occurrence of mucositis, and allopurinol mouth rinse (1 mg/ml) was ineffective in the prophylaxis of fluorouracil-induced mucositis. nan The effects of chlorhexidine mouthrinses, used as a supplement to mechanical oral hygiene measures, were studied in patients receiving treatment for acute leukemia. Twenty-eight patients were randomly divided into two groups. During two periods, when the patients were taking medication for the leukemia, one group rinsed with a 0.2% chlorhexidine solution twice daily and the other group did not. Chlorhexidine had no effects of any clinical significance on parameters such as number of days with fever, number of oral lesions, plaque score, gingival bleeding score, or occurrence of candidiasis. There was, however, an increased number of patients who had a burning sensation in the mouth, and a tendency toward increased numbers of salivary enterococci, enterobacteria, and/or Pseudomonas in patients who rinsed with chlorhexidine. The results of the present study do not support the use of chlorhexidine mouthrinses in patients who are able to maintain good oral hygiene by mechanical means during their illness. In this prospective multicentre trial, 90 patients undergoing autologous stem cell transplantation (ASCT) were randomised to receive (n=43) or not receive (n=47) amifostine 910 mg/m(2) prior to melphalan 200 mg/m(2). Patients were monitored for regimen-related toxicity, engraftment, supportive care, response and survival. Both groups underwent ASCT at a median of 8 months from diagnosis and were matched for disease characteristics, prior therapy and pre-ASCT disease responsiveness. Amifostine infusional side-effects were frequent, occurring in 65% of patients, but of mild severity. Amifostine use was associated with a reduction in the median grade of oral mucositis (1 vs 2, P=0.01) and the frequency of severe (WHO grades 3 or 4) mucositis (12 vs 33%, P=0.02), but no reduction in the requirement for parenteral nutrition or analgesic use. Conversion to complete remission post-ASCT occurred in 30 and 14% of the amifostine and control groups, respectively (P=0.09). With a median follow-up of 35 months, there was no statistically significant difference between the median progression-free or overall survival times for the two groups. We conclude that amifostine can be safely administered prior to high-dose melphalan and significantly reduces the frequency and severity of therapy-induced oral mucositis. Mouth sores and/or difficulty swallowing are common and painful consequences of cytotoxic chemotherapy for cancer. In previous studies oral glutamine was found to protect animals from the effects of whole abdominal radiation and methotrexate-induced enteritis. Glutamine also was found to reduce oral mucositis in a nonrandomized pilot study in humans. Therefore, the authors attempted to determine the efficacy of oral glutamine in a randomized, double blind, crossover trial in cancer patients receiving chemotherapy.
                Twenty-four patients (16 children and 8 adults) received glutamine or placebo (glycine) suspension (2 g amino acid/M2/dose twice daily) to swish and swallow on days of chemotherapy administration and for at least 14 additional days. Patients completed a calendar indicating days of mouth pain associated with each chemotherapy course and the effect of mouth pain on oral intake.
                Paired data indicated significant amelioration of stomatitis associated with glutamine administration after chemotherapy. The duration of mouth pain was 4.5 days less in chemotherapy courses in which glutamine supplementation was compared with placebo (Wilcoxon's signed rank test, P=0.0005). The severity of oral pain also was reduced significantly when glutamine was provided with chemotherapy (the amount of days mucositis restricted oral intake to soft foods [> or =Grade 2; Modified Eastern Cooperative Oncology Group grading system] was 4 days less with glutamine compared with placebo; Wilcoxon's signed rank test, P=0.002).
                Low dose oral glutamine supplementation during and after chemotherapy significantly reduced both the duration and severity of chemotherapy-associated stomatitis. Oral glutamine appears to be a simple and useful measure to increase the comfort of many patients at high risk of developing mouth sores as a consequence of intensive cancer chemotherapy. Multiple center randomized controlled double blind clinical trait was conducted to evaluate the anti-radiotherapy effect by SOD (produced by Hunan Biochemical Work) in 159 patients. Injection of 4000U SOD immediately after receiving radiotherapy significantly reduced the occurrence rate of skin, oral mucosal, pelvic visceral and systematic adverse reaction, only the reduction of leukopenia did not reach the statistical significant level. No adverse effect of SOD injection was observed. The results suggest that SOD is a safe and effective agent to attenuate the radiotherapy reactions. To evaluate the influence of oral glutamine on radiation-induced oral mucositis in the radiotherapy of head and neck cancer.
                From July 1997 through June 1998, 17 patients with head and neck cancer receiving primary or adjuvant irradiation were randomized to either glutamine suspension (16 g in 240 ml normal saline) (n = 8) or placebo (normal saline) (n = 9) arm. Patients were instructed to swish the test solutions (30 ml) four times per day. All patients received half-mouth irradiation at least. Patients were treated 1.8 Gy per fraction daily, 5 days a week. We evaluated the grading of oral mucositis daily fraction at each day of treatment until 45 Gy/25 fractions. World Health Organization (WHO) step analgesic medication and body weight change were compared between the two arms.
                The duration of objective oral mucositis > or = Grade 1 (p = 0.0097), Grade 2 (p = 0.0232), and Grade 3 (p = 0.0168) was shorter in the glutamine arm. Mean maximum grade of objective oral mucositis was less severe in the glutamine arm (1.6 vs. 2.6) (p = 0.0058). Glutamine did not reduce the duration and severity of subjective oral mucositis except for duration > or = Grade 3 (p = 0.0386). In the analysis of mean maximum WHO step of analgesic medication, there was no statistical difference (p = 0.5374) between the two arms. Mean body weight change was also not significantly different (p = 0.8070).
                Oral glutamine may significantly reduce the duration and severity of objective oral mucositis during radiotherapy. It may shorten the duration of > or = Grade 3 subjective mucositis. Oropharyngeal mucositis is the most common acute non-hematology toxicity in nasopharyngeal carcinoma (NPC) treated with radiotherapy, especially in the concomitant chemoradiotherapy of local advanced NPC patients. This study was designed to observe the effect of traditional Chinese medicine against acute oropharyngeal mucositis from chemoradiotherapy in patients with local advanced NPC.
                A total of 101 patients in stage III- IVa (Fuzhou 1992) were enrolled into this prospective randomized clinical trial. The cases were divided into treatment group (52 cases) and control group (49 cases). The median doses were 70.31+/-1.21 Gy for the treatment group and 70.78+/-1.95 Gy for the control group, respectively. Chemotherapy was concomitant with radiotherapy [single agent cisplatin (DDP,30 mg/m(2)) 6 times from first to sixth week of radiotherapy duration]. The patients of treatment group took 5-8 times of Chinese medicine daily and those of control group took 5-8 times of Dobell's solution daily.The observation indices included the degree of oropharyngeal and hematological toxicity, radiotherapy duration, and curative effect.
                (1)Oropharyngeal toxicity: there was no 0 degree oropharyngeal toxicity in both groups, I degree toxicity in 29 cases (55.77%) and 2 cases (4.08%), II degree toxicity in 18 cases (34.62%) and 17 cases (30.69%), III degree toxicity in 5 cases (9.62%) and 22 cases (44.89%), IV degree toxicity in 0 case (0%) and 8 cases (16.33%); there was statistical significance of difference between the two groups (P=0.000). (2)Hematological toxicity: there was no IV degree hematological toxicity in both groups. WBC toxicity (Z=-0.604,P=0.546), neutrophilic granulocyte toxicity (Z=-0.226,P=0.821), and platelet toxicity (Z=-0.099,P=0.922) were compared; there was no statistic significance of difference (P >0.05); (3)Radiotherapy duration: The radiotherapy duration of two groups were 49.79+/-1.83 days and 51.00+/-4.46 days; there was no statistic significance of difference (P=0.082). (4)Curative effects: The curative effects of two groups were:complete remission (CR) 76.92% (40/52) and 69.39% (34/49), partial remission (PR) 23.08% (12/52) and 30.61% (15/49); there was no statistical significance of difference (P=0.392).
                Chinese medicine was effective in reducing acute oropharyngeal toxicity resulting from chemoradiotherapy in patients with local advanced NPC. Furthermore, the apparent side effects of Chinese medicine in this study have not been observed. Chinese medicine treatment did not affect the short-term clinical outcome. Mucositis can be a serious complication of cancer treatment. Palifermin reduces mucositis when given in multiple doses to patients undergoing hematopoietic stem-cell transplantation.
                To evaluate the efficacy of palifermin given as a single dose before each cycle in patients receiving multicycle chemotherapy.
                Randomized, double-blind, placebo-controlled trial. (ClinicalTrials.gov registration number: NCT00267046)
                The University of Texas M.D. Anderson Cancer Center, Houston, Texas.
                48 patients with sarcoma were randomly assigned in a 2:1 ratio to receive palifermin or placebo. All patients received doxorubicin-based chemotherapy (90 mg per m(2) of body surface area over 3 days, by infusion).
                Palifermin (180 µg per kg of body weight) or placebo was administered intravenously as a single dose 3 days before each chemotherapy cycle (maximum, 6 cycles). Patients who had severe mucositis received open-label palifermin in subsequent cycles.
                Oral assessment of mucositis by using World Health Organization (WHO) oral toxicity scale (grades 0 to 4), with moderate to severe mucositis (grades 2 to 4) as the main outcomes; patient-reported outcome questionnaire; and daily symptom record diary.
                A median of 6 blinded cycles (range, 1 to 6) were completed by the palifermin group and 2 (range, 1 to 6) by the placebo group. Compared with placebo, palifermin reduced the cumulative incidence of moderate to severe (grade 2 or higher) mucositis (44% vs. 88%; P < 0.001; difference, -44 percentage points [95% CI, -71 to -16 percentage points) and severe (grade 3 or 4) mucositis (13% vs. 51%; P = 0.002; difference, -38 percentage points [CI, -67 to -9 percentage points]). The main adverse effects were thickening of oral mucosa (72% in the palifermin group vs. 31% in the placebo group; P = 0.007) and altered taste. Seven of the 8 patients who had severe mucositis in the placebo group received open-label palifermin. None of these patients had severe mucositis in the subsequent cycles (a total of 17) with open-label palifermin.
                Study limitations include smaller sample size for the control group, inclusion of only patients with sarcoma, and perceived unblinding of the treatment because of notable differences between the biologic effects of palifermin and placebo.
                A single dose of palifermin before each cycle reduced the incidence and severity of mucositis. The drug was generally well tolerated, but most patients experienced thickening of oral mucosa. Further investigation is needed to determine whether palifermin use will facilitate greater adherence to chemotherapy regimens by reducing mucositis. The invasion and colonization of oral cavity mucosal tissues by microflora may contribute to the pathophysiology of ulcerative oral mucositis (UOM). Iseganan is an analog of protegrin-1, a naturally occurring peptide with broad-spectrum microbicidal activity. A randomized, double-blind, placebo-controlled study was conducted to evaluate the efficacy and safety of iseganan in preventing UOM after stomatotoxic therapy. Patients received an oral rinse, consisting of iseganan 9mg or placebo, to be swished/swallowed six times daily, starting with stomatotoxic therapy and continuing up to 21 days. Patients were assessed for stomatitis and UOM, and administered a questionnaire evaluating mouth pain and difficulty swallowing thrice weekly. The primary study efficacy endpoint was the proportion of patients who did not have peak stomatitis NCI-CTC grade >or=2. Between November 2001 and June 2002, 502 patients were randomized to receive iseganan (251) or placebo (251). Equivalent numbers of patients in both cohorts received bone marrow or peripheral blood allogeneic or autologous stem cell transplantation (SCT). Forty-three percent and 37% of iseganan and placebo patients, respectively, did not have peak stomatitis grade =2 (P = 0.182). There was no significant difference between the cohorts in stomatitis severity, incidence of UOM, peak mouth pain, peak difficulty swallowing, amount of opiate analgesics used, or adverse event type or incidence. A major impact of Iseganan on reducing stomatitis, UOM, or its clinical sequelae in patients receiving stomatotoxic therapy was not detected on this study. The purpose of this study was to assess the value of sucralfate suspension in prevention of oral mucositis and for reduction of oral pain in patients who develop mucositis during radiation therapy.
                The study was a double-blind, placebo-controlled, randomized prospective trial of a sucralfate suspension in the prevention and management of oral mucositis during radiation therapy. Oral mucositis was assessed using a quantitative scale and symptoms were assessed using visual analogue scales. The statistical model was developed to detect a 40% reduction in mucositis.
                No statistically significant reduction in mucositis was seen. Early during radiation therapy less oral pain was reported in the sucralfate group, but as treatment progressed all patients experienced pain. Patients in the sucralfate group were prescribed topical and systemic analgesics later in the course of radiation therapy.
                Prophylactic oral rinsing with sucralfate did not prevent oral ulcerative mucositis. Sucralfate may reduce the experience of pain during radiation therapy. To determine the prophylactic properties of amifostine against acute and late toxicities from radiochemotherapy in patients with head-and-neck cancer.
                Fifty patients were randomized to receive conventional radiotherapy (RT) (2-Gy fractions, 5 days weekly, to a total of 60-74 Gy, depending on the tumor localization and TNM classification) and carboplatin (90 mg/m(2) infusion once per week before RT). Amifostine (300 mg/m(2)) was administered in the study group only 15-30 min before RT for 6-7.5 weeks. The primary study end point was the grading of acute and late nonhematologic toxicities (mucositis, dysphagia, xerostomia) induced by radiochemotherapy. Secondary end points included treatment duration, hematologic toxicity, and clinical outcome.
                The treatment duration was significantly shorter in the amifostine-treated group (p = 0.013), because treatment interruptions were more frequent in the control group. Acute toxicities (mucositis and dysphagia) were less severe in the amifostine-treated group. By Week 3, all in the control group experienced Grade 2 mucositis compared with only 9% in the amifostine-treated group (p <0.0001). By Week 5, 52.2% of the patients in the control group experienced Grade 4 mucositis compared with 4.5% in the amifostine-treated group (p = 0.0006). Similar results were obtained for dysphagia. At 3 months of follow-up, only 27% of patients in the study group experienced Grade 2 xerostomia compared with 73.9% in the control group (p = 0.0001). Eighteen months after cessation of therapy, the proportion of patients with Grade 2 xerostomia was 4.5% vs. 30.4% for each respective treatment group (p = 0.047). Cytoprotection with amifostine did not affect treatment outcome, with 90.9% complete responses in the amifostine-treated group compared with 78.3% in the control group (p = 0.414).
                Amifostine was effective in reducing mucositis and dysphagia resulting from radiochemotherapy in patients with head-and-neck cancer. Furthermore, amifostine reduced the severity of late xerostomia, a side effect of RT with long-lasting consequences. Amifostine treatment did not affect the clinical outcome. Patients of head and neck cancer undergoing radiotherapy develop oral mucositis. The severity of mucositis may also depend on the time of administration of radiation apart from patient-related factors. The most radiosensitive phase of the cell cycle (G2-M) occurs in the late afternoon and evening in human oral mucosa; therefore, it is more vulnerable to radiation injury in the evening. The present study evaluated prospectively the severity of acute oral mucositis in head and neck carcinoma patients irradiated in the morning (08:00-11:00 h) versus late afternoon/evening (15:00-18:00 h).
                A total of 212 patients of head and neck carcinoma were randomised to morning (08:00-11:00 h) and evening (15:00-18:00 h) groups. The grades of oral mucosa ulceration were compared in the two groups.
                The grades of mucositis were marginally higher in the evening-irradiated group than in the morning-irradiated group 38% vs. 26% (p = 0.08).
                The observed incidence of grade III/IV mucositis in morning vs. evening irradiated patients may be because of the existence of circadian rhythm in the cell cycle of normal mucosa. This knowledge may provide a possibility of treating the patients with decreased toxicity to oral mucosa. The aim of the study was to test the hypothesis that aerobic Gram-negative bacteria (AGNB) play a crucial role in the pathogenesis of radiation-induced mucositis; consequently, selective elimination of these bacteria from the oral flora should result in a reduction of the mucositis.
                Head-and-neck cancer patients, when scheduled for treatment by external beam radiation therapy (EBRT), were randomized for prophylactic treatment with an oral paste containing either a placebo or a combination of the antibiotics polymyxin E, tobramycin, and amphotericin B (PTA group). Weekly, the objective and subjective mucositis scores and microbiologic counts of the oral flora were noted. The primary study endpoint was the mucositis grade after 3 weeks of EBRT.
                Seventy-seven patients were evaluable. No statistically significant difference for the objective and subjective mucositis scores was observed between the two study arms (p = 0.33). The percentage of patients with positive cultures of AGNB was significantly reduced in the PTA group (p = 0.01). However, complete eradication of AGNB was not achieved.
                Selective elimination of AGNB of the oral flora did not result in a reduction of radiation-induced mucositis and therefore does not support the hypothesis that these bacteria play a crucial role in the pathogenesis of mucositis. Oral mucositis is a complication of intensive chemotherapy and radiotherapy with no effective treatment. We tested the ability of palifermin (recombinant human keratinocyte growth factor) to decrease oral mucosal injury induced by cytotoxic therapy.
                This double-blind study compared the effect of palifermin with that of a placebo on the development of oral mucositis in 212 patients with hematologic cancers; 106 patients received palifermin (60 microg per kilogram of body weight per day) and 106 received a placebo intravenously for three consecutive days immediately before the initiation of conditioning therapy (fractionated total-body irradiation plus high-dose chemotherapy) and after autologous hematopoietic stem-cell transplantation. Oral mucositis was evaluated daily for 28 days after transplantation.
                The incidence of oral mucositis of World Health Organization (WHO) grade 3 or 4 was 63 percent in the palifermin group and 98 percent in the placebo group (P<0.001). Among patients with this degree of mucositis, the median duration of mucositis was 6 days (range, 1 to 22) in the palifermin group and 9 days (range, 1 to 27) in the placebo group. Among all patients, regardless of the occurrence of mucositis, the median duration of oral mucositis of WHO grade 3 or 4 was 3 days (range, 0 to 22) in the palifermin group and 9 days (range, 0 to 27) in the placebo group (P<0.001). As compared with placebo, palifermin was associated with significant reductions in the incidence of grade 4 oral mucositis (20 percent vs. 62 percent, P<0.001), patient-reported soreness of the mouth and throat (area-under-the-curve score, 29.0 [range, 0 to 98] vs. 46.8 [range, 0 to 110]; P<0.001), the use of opioid analgesics (median, 212 mg of morphine equivalents [range, 0 to 9418] vs. 535 mg of morphine equivalents [range, 0 to 9418], P<0.001), and the incidence of use of total parenteral nutrition (31 percent vs. 55 percent, P<0.001). Adverse events, mainly rash, pruritus, erythema, mouth and tongue disorders, and taste alteration, were mild to moderate in severity and were transient.
                Palifermin reduced the duration and severity of oral mucositis after intensive chemotherapy and radiotherapy for hematologic cancers. Oral mucositis (OM) causes significant morbidity during the course of radiotherapy (RT) treatment of head-and-neck cancer. It is hypothesized that infection plays a role in the development of OM. We tested the efficacy of iseganan HCl (iseganan), a synthetic peptide with broad-spectrum antimicrobial activity, for preventing RT-associated OM.
                A multinational, randomized, double-blind, controlled trial was performed on patients receiving primary RT, primary chemoradiotherapy or postoperative RT. Patients were randomized to receive iseganan oral solution plus standard-of-care oral hygiene (SOC), placebo plus SOC, or SOC alone throughout the RT administration period. The severity of OM was assessed by NCI-CTC scoring and clinical symptoms by patient questionnaire.
                A total of 545 patients were randomized to the study. Nine percent of the patients in both the iseganan and placebo groups did not develop ulcerative OM (Grades 2, 3, 4) (p = 0.998) whereas only 2% of the patients receiving SOC alone remained free of oral ulceration (p = 0.049). The maximum severity of mouth pain and difficulty swallowing did not differ in patients treated with iseganan or placebo. However, patients in both intervention groups reported less mouth pain and difficulty swallowing than did patients receiving SOC alone. Nausea was the only adverse event that occurred with >/=5% increased frequency in the iseganan group than in either the placebo or SOC groups (51% vs. 42% vs. 46%). Adverse events leading to study drug discontinuation and death did not differ significantly between groups.
                Iseganan oral solution was safe but did not reduce the risk for developing ulcerative OM relative to placebo. Intensified oral hygiene or the administration of the vehicle used to deliver study drug in this trial appears to have reduced the risk and severity of OM. Our results suggest that antimicrobial intervention may not meaningfully affect the pathogenesis of radiation-induced OM. To compare subcutaneously given molgramostim (GM-CSF) and sucralfate mouth washings to sucralfate mouth washings in prevention of radiation-induced mucositis.
                Forty head and neck cancer patients were randomly assigned to use either GM-CSF and sucralfate (n = 20) or sucralfate alone (n = 20) during radiotherapy. Sucralfate was used as 1.0 g mouth washing 6 times daily after the first 10 Gy of radiotherapy, and 150-300 microg GM-CSF was given subcutaneously. The grade of radiation mucositis and blood cell counts were monitored weekly. Salivary lactoferrin was measured as a surrogate marker for oral mucositis.
                We found no significant difference between the molgramostim and the control groups in the oral mucositis grade, oral pain, use of analgesic drugs, weight loss, or survival. The median maximum neutrophil counts (median, 9.2 x 10(9)/L vs. 5.9 x 10(9)/L, p = 0.0005), eosinophil counts (median, 1.3 x 10(9)/L vs. 0.2 x 10(9)/L, p = 0.0004), and salivary lactoferrin concentrations were higher in patients who received GM-CSF. The most common toxicities in the GM-CSF plus sucralfate group were skin reactions at the GM-CSF injection site (65%), fever (30%), bone pain (25%), and nausea (15%), whereas the toxicity of sucralfate given alone was minimal.
                We found no evidence indicating that subcutaneously given GM-CSF reduces the severity of radiation-induced mucositis. Radiotherapy-induced mucositis decreases the quality of life by impairing eating, swallowing, and talking and by disturbing sleep. Mucositis may also predispose to local and systemic infections and may cause interruption of radiotherapy course. We studied the efficacy of sucralfate suspension in the prevention and management of oral mucositis and pain during radiotherapy in a double-blind, placebo-controlled, randomized, prospective trial. Twenty-eight patients with head and neck cancer were included in the study. The patients were randomized to use either sucralfate mouth washing (n = 18) or placebo washing (n = 10) during irradiation. Oral mucositis and symptoms were assessed by the same physician using Radiation Therapy Oncology Group Acute Radiation Morbidity Scoring criteria. All patients developed varying degrees of radiation-induced mucositis. Grade 4 mucositis was not encountered in any patient. One patient had grade 1, seven patients grade 2, and two patients grade 3 mucositis in placebo group. In sucralfate group, nine patients each had grade 1 and grade 2 with no grade 3 mucositis. Patients in the sucralfate group experienced significantly lower degree of mucositis than placebo group (p < 0.05). Sucralfate mouth washing is beneficial in decreasing the intensity of radiation-induced mucositis and oral discomfort. It is cheap, easy to administer with no serious side effect, and may be routinely used in patients receiving head and neck radiotherapy. Radiotherapy of head and neck malignancies is accompanied by oral discomforts, such as epithelitis, pain and functional impairment. This can lead to chronic sequalae with subjective distress such as loss of taste and xerostomia and pronounced decrease in quality of life. Thus, the need to reduce the mucosal damage following radiotherapy is obvious. Therefore, we investigated the possible ability of sucralfate, an aluminium hydroxide complex of sulphated sucrose used in the treatment of gastric ulcer, in preventing oral discomfort in patients treated with curative intent for malignancies in the head and neck region. The study was double-blind, placebo-controlled and randomized and included 50 consecutive patients. The study demonstrated that the proportion of patients with severe mucosal reactions was significantly lower in the sucralfate group than in the placebo group. Radiation therapy is an important curative modality in the treatment of patients with head and neck cancer. However, radiation-induced changes in the oral cavity, such as xerostomia and mucositis, are among the most debilitating treatment sequelae experienced by patients undergoing radiation therapy, and attempts at ameliorating these side effects have been poor at best. Pilocarpine has been approved for post-radiation xerostomia, and the effect of its use during radiation therapy on salivary flow, xerostomia, mucositis, and quality of life (QOL) was assessed in a phase III study conducted by the Radiation Therapy Oncology Group (RTOG 97-09). In total, 245 evaluable patients were randomized to pilocarpine or placebo. Selected patients were required to have > or = 50% of the volume of the major salivary glands receive > or = 50Gy; to agree to provide stimulated and unstimulated samples of saliva (measured in g) before treatment, at the end of treatment, and 3 and 6 months after completion of radiation therapy; and to complete the University of Washington Head and Neck Symptom Scale. Following the completion of radiation therapy, the average unstimulated salivary flow was statistically greater in the pilocarpine group, whereas no difference was noted following parotid stimulation. There was no effect on the amelioration of mucositis. The results of the QOL scales did not reveal any significant difference between the pilocarpine and placebo groups with regard to xerostomia and mucositis. The significant difference in unstimulated salivary flow supports the concomitant use of oral pilocarpine to decrease radiation-associated xerostomia. However, the absent correlation between improved salivary flow and QOL scores is of some concern (though not a new finding) and may be related to the existence of comorbidities and the lack of effect on mucositis. Clinical trials demonstrated the efficacy and safety of intravenous (i.v.) or subcutaneous (s.c.) amifostine for reducing xerostomia and mucositis after radiotherapy or radiochemotherapy for head-and-neck cancer. This randomized, double-blinded, placebo-controlled, phase III study evaluated the efficacy and safety of i.v. amifostine during radiochemotherapy for head-and-neck cancer.
                Patients from European and American study centers received i.v. amifostine 300 mg/m2 (n = 67) or placebo (n = 65) before carboplatin 70 mg/m2 and radiotherapy on Days 1 to 5 and 21 to 25, and i.v. amifostine 200 mg/m2 or placebo before radiotherapy on other days.
                Toxicity incidences were (amifostine, placebo, p value): Grade 2 or higher acute xerostomia (39%, 34%, 0.715), Grade 3 or higher acute mucositis (39%, 22%, 0.055), Grade 2 or higher late xerostomia (37%, 24%, 0.235), and Grade 3 or higher treatment-related adverse events (42%, 20%, 0.008). One-year rates of locoregional failure, progression-free survival, and overall survival were not significantly different between treatments.
                The used amifostine doses were not able to reduce the toxicity of simultaneous radiochemotherapy for head-and-neck cancer. The safety of amifostine and the lack of tumor protection were consistent with previous studies. Oral enzymes act as a potent antiinflammatory, antiedematous agents thereby decreasing acute toxigenic effect of radiation and increasing compliance, quality of life of our patients. Fifty patients were randomized 25 allocated in enzyme and radiotherapy arm, 25 in radiotherapy alone. Pre RT and post RT biopsies were taken from both arms. In our study it was found that there was clinical, histopathological as well as statistical significant difference in both arms. The enzyme arm patients had mucostis of grade I in 76%, grade II in 12%, grade III in 8% while as 8% had grade I, 68% grade II, 24% had grade III in RT arm alone. In enzyme patients skin reactions of grade I in 72%, 20% had grade II, 8% had grade III. In control arm 12% had grade I, 76% had grade II, 8% had grade III skin reaction. nan Because all patients receiving bone marrow transplant (BMT) and peripheral blood progenitor cell transplant (PBPCT) experience gastrointestinal (GI) toxicity from the preparative regimen of chemotherapy, with or without radiation, oral glutamine was administered during the preparatory regimen and after transplant to maintain GI structure and function.
                To evaluate effects of oral glutamine on nutritional status and overall outcome, a prospective, randomized, double-blinded study was performed on 58 autologous and allogeneic BMT patients. Patients received 30 g of oral glutamine or placebo daily.
                The trends of decreased median length of stay and the median number of days of total parenteral nutrition (TPN) were seen in the group supplemented with the >0.285-g/kg (the recommended dosage) dose of glutamine; however, there was no statistically significant difference in the nutritional status and overall patient outcome as assessed by days receiving TPN, number of days required until oral intake resumed, length of hospitalization, number of days and highest grade of mucositis, and quantity and number of days of diarrhea.
                This study does not support the hypothesis that oral glutamine may offer benefit. Further investigation is required regarding clinical tools for determining effectiveness, administration for tolerance and compliance, dosage, and potential of oral glutamine usage. The purpose was to evaluate prevention of oral mucositis (OM) using chlorhexidine compared with placebo and with oral cooling (cryotherapy) during fluorouracil (5-FU)-based chemotherapy in gastrointestinal (GI) cancer.
                Patients with previously untreated GI cancer receiving bolus 5-FU/leucovorin chemotherapy were randomized to chlorhexidine mouthrinse 3 times a day for 3 weeks (Arm A), double-blind placebo (normal saline) with the same dose and frequency (Arm B), or cryotherapy with crushed ice 45 minutes during chemotherapy (Arm C). Patients self-reported on severity (CTC-grading) and duration of OM.
                Among 225 patients randomized, 206 answered the questionnaire (70, 64, and 63 patients in Arms A, B, and C, respectively) and were well balanced with respect to diagnoses, stage, age, sex, smoking habits, and performance status. Mucositis grade 3-4 occurred more frequently in Arm B (33%) than in A (13%, P< .01) and C (11%, P< .005). Duration was significantly longer in B than in both A (P= .035) and C (P= .003).
                The frequency and duration of OM are significantly improved by prophylactic chlorhexidine and by cryotherapy. The latter is easy and inexpensive but has limited use, as it is drug- and schedule-dependent. The current study is the first double-blind randomized evaluation of prophylactic chlorhexidine in a large adult patient population with solid tumors receiving highly OM-inducing chemotherapy. A role for chlorhexidine in the prevention of OM is suggested, which should be evaluated further. Severe oral mucositis is a major cause of morbidity following allogeneic hematopoietic stem cell transplantation (AHSCT). Cryotherapy, that is, the application of ice chips on the mucosa of the oral cavity during the administration of antineoplastic agents, may reduce the incidence and severity of chemotherapy-related oral mucositis. In this multicenter randomized study, we addressed whether cryotherapy during MTX administration is effective in the prevention of severe oral mucositis in patients undergoing myeloablative AHSCT. One hundred and thirty patients undergoing myeloablative AHSCT and MTX-containing GVHD prophylaxis were enrolled and randomized to receive or not receive cryotherapy during MTX administration. The incidence of severe (grade 3-4) oral mucositis, the primary end point of the study, was comparable in patients receiving or not cryotherapy. Moreover, no difference was observed in the incidence of oral mucositis grade 2-4 and the duration of oral mucositis grade 3-4 or 2-4, or in the kinetics of mucositis over time. In univariate and multivariate analysis, severe oral mucositis correlated with TBI in the conditioning regimen and lack of folinic acid rescue following MTX administration. Thus, cryotherapy during MTX administration does not reduce severe oral mucositis in patients undergoing myeloablative allogeneic HSCT. Future studies will assess cryotherapy before allogeneic HSCT. Patients undergoing cancer chemotherapy frequently suffer from mucositis, particularly if they become leukopenic (leucocytes <1000/microL). To identify a possible benefit from antiseptic rinsing of the oral cavity, 47 patients were randomized to rinse either with a chlorhexidine-based product (chlorhexidine concentration 0.3%; N=24) or with an amine-stannous fluoride combination (control group; N=23). Patients were asked to rinse three times a day for 30s from the beginning of chemotherapy until the end of leukopenia. Before rinsing, as well as during and after leukopenia, aerobic and anaerobic bacteria in the oral cavity were counted. At the same time, the patients were assessed for mucositis. In the chlorhexidine-based group, a significant decrease of the aerobic (P=0.042) and anaerobic (P=0.008) bacterial flora was identified. In the control group, the numbers of aerobic and anaerobic bacteria remained unchanged (P>0.05). Fifteen patients in the chlorhexidine-based group had a C-reactive protein (CRP) increase >50mg/L, compared with only eight patients in the control group [odds ratio: 3.13, confidence interval (CI) 0.82-12.39]. Nine patients in the chlorhexidine-based group but only two patients in the control group developed severe mucositis. This difference was statistically significant with an odds ratio of 6.30 (CI: 1.02-49.67). As not all of the 47 patients developed severe leukopenia, a separate analysis was carried out for patients with <1000 leucocytes/microL for a minimum of three days. The results of the microbial counts were very similar, with a clear reduction in the chlorhexidine group and no major alterations in the control group. Twelve of 15 patients in the chlorhexidine-based group had a CRP >50mg/L whereas only eight of 15 patients did so in the control group, which can be regarded as a slightly elevated risk for a CRP increase in the former group. Seven of 15 patients developed severe mucositis in the chlorhexidine-based group, but only two of 15 patients in the control group. These differences were not significant, but patients treated with chlorhexidine-based product seemed to have more problems with inflammation of the oral mucous membranes, resulting in an elevated mucositis score and a CRP increase. Other parameters such as body temperature or application of antibiotics did not differ between the two groups. We conclude that treatment with the chlorhexidine-based product did not provide a clinical benefit for cancer chemotherapy patients. On the contrary, the risk of mucositis and clinical sequelae seems to be enhanced, although the counts of micro-organisms on the oral mucous membranes are significantly reduced. To investigate the efficacy and safety of Wobe-Mugos E (proteolytic enzymes) for amelioration of early side effects of radiotherapy for head-and-neck tumors, particularly oral mucositis.
                The study was a prospective, randomized, multicenter, placebo-controlled, triple-blind phase III study with parallel groups. 69 patients with carcinomas of the oropharynx or the oral cavity were enrolled between 1996 and 2000 in five centers; 54 of these were recruited in Dresden. Of the 69 patients, 61 (Dresden: 46) were available for analysis. The proteolytic enzymes tested (Wobe-Mugos E) comprised papain 100 mg, trypsin 40 mg, and chymotrypsin 40 mg.
                Wobe-Mugos E was well tolerated. For the maximum mucositis scores, no statistically significant differences were found between the placebo and the verum group. The average mucositis score over weeks 1-6 revealed a significant difference in favor of the placebo arm, based on an earlier onset of mucositis in the Wobe-Mugos E group.
                The present study failed to demonstrate any effect of treatment with Wobe-Mugos E on radiotherapy side effects in patients treated for head-and-neck tumors. In particular, there was no beneficial effect on radiation-induced early oral mucositis. Mucosal toxicity is dose limiting for etoposide. This may be related to the direct effects of etoposide on the mucosa. Twelve patients receiving etoposide 1800 mg/m2 as part of a myeloablative pre-transplant regimen were randomized to receive propantheline 30 mg or placebo orally every 6 h for six doses. Mucositis was less frequent (2 of 6 vs 5 of 6) and less severe (p = 0.05) in the propantheline arm. There were no differences in tumor response or survival between the two groups. Propantheline is an anticholinergic that causes xerostomia by decreasing salivation. Propantheline may reduce the salivary excretion of etoposide and could reduce its toxic effects on the mucosa. Propantheline is effective in reducing the incidence and severity of mucositis in patients receiving high-dose etoposide. Conditioning chemoradiotherapy damages the mucosal barrier of the mouth and throat and often produces severe oral inflammation and infection. In a prospective, double-blind, randomized study, we examined the use of a chlorhexidine digluconate mouthrinse for prophylaxis against oral mucosal complications in 51 bone marrow transplant patients. Use of chlorhexidine mouthrinse produced significant reductions in the incidence and severity of oral mucositis. Mucositis also resolved more quickly in patients receiving chlorhexidine. Concomitant reductions in total oral streptococci (p less than 0.02-p less than 0.001) and oral candida (p less than 0.004) were seen in patients using chlorhexidine. Persistent clinical oral candidiasis (thrush) was observed in 15 to 27 control group patients (56%), but only transiently in two (8%) of 24 patients who used chlorhexidine rinse (p less than 0.001). Five of 27 control group patients (19%) had candidemia, while no candidemia was observed in the chlorhexidine group (p less than 0.03). Three deaths from disseminated candidiasis occurred in the placebo group; none occurred in patients who received chlorhexidine. Prophylactic use of chlorhexidine mouthrinse produces reductions in oral soft tissue disease and oral microbial burden in patients undergoing bone marrow transplantation. The reductions in mucositis and in oral candida infections observed with prophylactic chlorhexidine mouthrinse represent a significant advantage for patients undergoing marrow transplantation. The prophylactic value of twice-daily mouth rinses with a solution of 0.1% chlorhexidine gluconate in minimizing oral complications during remission-induction chemotherapy was tested in sixteen patients with acute myeloblastic leukemia. The study design was double blind with a placebo control. Standardized measurement indices were employed to assess the dental plaque levels and the degree of gingivitis and mucositis during remission-induction. The treatment group demonstrated superior oral health on the basis of each of these measurement parameters. A moderate increase in tooth staining was observed in the treatment group. The results also suggested the potential value of chlorhexidine mouth rinses in the prophylaxis of oral candidiasis in the myelosuppressed patient. Oral flora is thought to contribute to irradiation mucositis in patients with head and neck cancer. Neglect of oral hygienic care may also contribute to mucositis. The purpose of this prospective, randomized, placebo-controlled, double-blind study was to evaluate the effect of chlorhexidine 0.1% mouthrinses on oral flora and irradiation mucositis. This study included 30 patients with head and neck cancer who had comparable irradiation portals. One group (N = 15) rinsed four times daily with chlorhexidine 0.1%, the other group (N = 15) with a placebo. The oral flora was cultured (oral washing technique) twice before and three times per week during the period of radiotherapy. On the same days, the severity of mucositis was determined. The colonization index of viridans streptococci was significantly reduced only after 5 weeks of chlorhexidine 0.1% treatment. The colonization patterns of Candida species, Streptococcus faecalis, staphylococci, and Enterobacteriaceae, Pseudomonadaceae, and Acinetobacter species were not influenced by 5 weeks of use of chlorhexidine rinses when compared with the placebo. No differences were seen between the two study groups in the development and severity of mucositis. In conclusion, suppression of oral flora and a lowering of the severity of mucositis by means of disinfecting mouthrinses were not successful. Oral mucositis is a frequent side effect of myeloablative chemo- and radiotherapy preceding stem cell transplantation. It causes pain, poor food intake, and is a port of entry for infection. We studied whether GM-CSF applied topically in the oral cavity can prevent or ameliorate this mucositis. In 36 consecutive patients undergoing a stem cell transplantation, we performed a double-blind placebo-controlled study of 300 micrograms GM-CSF in a 2% methylcellulose gel daily versus a 2% methylcellulose gel alone. Both were locally applied in the oral cavity. The primary end-point was mucositis as measured by the WHO toxicity scale for mucositis, oral assessment scale, and a subjective pain scale, all scored daily. The secondary end-points were need to give parenteral nutrition and morphine, incidence of fever and infections, and duration of neutropenia and hospitalization. No differences were found in the median subjective pain scores, WHO scores, and oral assessment scores between the placebo and the GM-CSF groups. In both groups, nine patients required morphine for pain control. Ten patients in the placebo group and 11 in the GM-CSF group received parenteral nutrition. Documented infections, use of broad-spectrum antibiotics, and number of days with fever were similar in the placebo and the GM-CSF groups. The duration of neutropenia below 0.5 x 10(9)/l (median 14.5 days in the placebo group versus 17 days in the GM-CSF group) and the duration of hospitalization (28.5 versus 29 days) was also not significantly different. We found no beneficial effect of 300 micrograms GM-CSF dissolved in a 2% methylcellulose gel applied locally for chemo- and radiotherapy-induced mucositis in patients undergoing a stem cell transplantation. Uncontrolled clinical trials have shown that parenteral administration of GM-CSF reduces the frequency of chemotherapy-induced mucositis. The mechanism of this effect could be related to acceleration of haematopoiesis and/or increase in functional activation of WBC. We conducted a double-blind, placebo-controlled, dose ranging study of GM-CSF (mol-gramostim) mouthwash in patients with breast cancer during the first treatment cycle of a combination chemotherapy regimen which has historically produced dose-limiting (grade > or = 3) mucositis in approximately 39% of patients. Subjects were randomized to receive either placebo mouthwash (0.1 percent albumin) or one of four concentrations of GM-CSF mouthwash (0.01, 0.1, 1.0 or 10 mcg/ml). The primary endpoint was to evaluate the relationship between dose of GM-CSF mouthwash received and probability of grade > or = 3 mucositis using a logistic model. Solutions were administered four times daily starting within 24 hours of chemotherapy initiation and continuing until the end of the cycle (day 21). Mucositis was assessed on days 1-6, 10, 15 and 21. Day 6 plasma samples were assayed for GM-CSF. Forty-five patients were evaluable for response (nine per dosing group). A 42% risk (15/36) of mucositis grade > or = 3 was evident on day 15 in patients receiving GM-CSF compared to 2 of 9 patients on the placebo arm. No evidence of dose response was found by logistic regression. Five patients had a detectable plasma concentration of GM-CSF (56-209 pg/ml). A positive correlation between GM-CSF dose and leukocyte recovery was noted (P = 0.04). A randomized phase 2 study was performed to investigate the efficacy/toxicity of combining concomitant boost radiation and weekly carboplatin/paclitaxel with or without amifostine in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN).
                Patients with newly diagnosed, locally advanced stage III or IV SCCHN received 4 weekly doses of carboplatin (area under the curve, 1.5) and paclitaxel (45 mg/m(2)) concurrently with concomitant boost radiation consisting of 72 grays in 42 fractions over 6 weeks (every day for 18 days, twice a day for 12 days) (grading determined according to the TNM staging system). All patients were randomized to subcutaneous daily amifostine at a dose of 500 mg (Arm A) or no amifostine (Arm B). Toxicity data were collected weekly, and saliva collection was performed with and without citric acid stimulation. To evaluate the correlation between serum cytokine levels and the severity of oral mucositis, we evaluated a subset (13 patients in Arm A and 11 patients in Arm B) of subjects at baseline and then on alternate weeks.
                Fifty-eight patients were enrolled, 29 in each arm. The majority of patients were men (90%), had stage IV disease (82%), and had the oropharynx as the primary tumor site (60%). Major toxicities encountered were similar in both arms and included grade 3 (as determined by Common Terminology Criteria for Adverse Events, version 3.0) mucositis (75% in Arm A and 70% in Arm B) and grade 2 xerostomia (41% in both arms). The median number of amifostine doses delivered was 28, with skin toxicity (grade 3 in 11 patients) as the limiting factor. Saliva production showed no difference between the arms. The median follow-up was 34 months, and only 5 failures had been encountered (2 local and 3 distant) at the time of last follow-up, with an overall survival rate of 89%. Neck dissection was performed in 25 patients; 5 patients demonstrated persistent disease and 4 patients were alive without disease recurrence at the time of last follow-up. The median time to percutaneous endoscopic gastrostomy removal was 9.6 months in Arm A and 10.4 months in Arm B. Only 1 patient remained percutaneous endoscopic gastrostomy-dependent at the time of last follow-up. A correlation was noted between levels of selected cytokines and mucositis severity, in which higher levels of proinflammatory cytokines (tumor necrosis factor, interleukin [IL]-1, and IL-6) and lower levels of anti-inflammatory cytokines (IL-13) were noted. No changes in C-reactive protein levels were noted.
                Four weekly doses of carboplatin/paclitaxel with concomitant boost radiation was found to be a highly effective regimen in this patient population with advanced SCCHN. The overall survival rate was 89%. The time to percutaneous endoscopic gastrostomy removal was prolonged. Amifostine given subcutaneously did not improve the rates of xerostomia and mucositis with this fairly intensive chemoradiotherapy regimen.
                2009 American Cancer Society. To observe the effect of Yangyin Humo Decoction (YHD) on oral mucomembranous reaction in patients with head-neck tumor undergoing radiotherapy.
                Forty-Forty-two patients with head-neck tumor undergoing radiotherapy were randomized equally into two groups. The two conventional Western medical treatment was administered to all, including intravenous dripping of 2% lidocaine 20 mL, dexamethasone 5 mg, gentamycin 80,000 units, vitamin B(12) 5 mg, dissolved in saline 250 mL, and 5% sodium bicarbonate solution for gargling, but to the patients in the tested group, YHD was given additionally. The medication was started simultaneously all through the whole course of the radiotherapy. Patients were examined every day to observe and compare the degree, initiating time, and repairing time of their oral lesions; the dosage of radiation they received was recorded as well.
                The degree of mucomembranous reaction that appeared in most patients in the test group was of grade 1-2, while in the control group, it was grade 2-3. The average time for oral lesion of 1, 2, 3 grades to be initiated in the test group was 12.0+/-1.1, 11.0+/-1.3 and 10.0+/-0.8 days, respectively, after radiation started, which was later than that in the control group (P<0.01). Moreover, the average repairing time for the lesions of grades 1, 2, and 3 in the test group was 3.0+/-0.7, 10.0+/-1.3 and 19.0+/-0.8 days, which were shorter than those in the control group respectively (P<0.01). The radiation applied on the primary tumor of patients with oral lesion of grade 1-3 in the test group was 24.2+/-2.2, 42.0+/-2.6 and 58.0+/-1.6 Gy on the average, respectively, which were higher than that applied on patients in the control group (P<0.05 or P<0.01).
                The Chinese herbal preparation YHD could alleviate oral mucomembranous reaction to radiation applied in patients with head-neck tumor. To test the effectiveness of a nurse-initiated systematic oral hygiene teaching program-PRO-SELF: Mouth Aware (PSMA)-in conjunction with two mouthwashes (0.12% chlorhexidine or sterile water) in preventing chemotherapy-induced oral mucositis.
                Randomized, double-blind, placebo-controlled, clinical trial.
                23 outpatient clinics and office practices in California.
                222 patients who were starting a cycle of mucositis-inducing chemotherapy.
                Participants were followed over three chemotherapy cycles. All patients were provided the PSMA program. Random assignment to a mouthwash occurred prior to the development of oral mucositis. Researchers used the Oral Assessment Guide to assess the patients oral cavities monthly (with the patients cycles of chemotherapy) and when patients reported any oral changes between cycles.
                Type of mouthwash, incidence, days to onset, and severity of chemotherapy-induced oral mucositis.
                No significant differences existed between the two mouthwashes in regard to incidence, days to onset, and severity of mucositis.
                Because chlorhexidine (S20 per pint) was no more effective than water, a substantial cost savings can be realized by rinsing with water. Interestingly, the PSMA program appeared to reduce the incidence of mucositis from on a prior estimate of 44% to less than 26%.
                A nursing prescription of a systematic oral hygiene program using water as a mouth rinse is cost efficient and may be effective in preventing oral mucositis. Stomatitis has been found to be a major dose-limiting toxicity from bolus 5-fluorouracil-based (5-FU) chemotherapy regimens, despite the use of oral cryotherapy. Pursuant to preliminary data which suggested that a chamomile mouthwash might ameliorate this toxicity, a prospective trial was developed to test chamomile in this situation.
                A Phase III, double-blind, placebo-controlled clinical trial was designed. Patients were entered into the study at the time of their first cycle of 5-FU-based chemotherapy. All patients received oral cryotherapy for 30 minutes with each dose of 5-FU. In addition, each patient was randomized to receive a chamomile or placebo mouthwash thrice daily for 14 days. Stomatitis scores were determined by health care providers and by patients themselves.
                There were 164 evaluable and well-stratified patients equally randomized to both treatment groups. There was no suggestion of any stomatitis difference between patients randomized to either protocol arm. There was also no suggestion of toxicity. Subset analysis did reveal unsuspected differential effects between males and females that could not be explained by reasons other than chance.
                The resultant data from this clinical trial did not support the prestudy hypothesis that chamomile could decrease 5-FU-induced stomatitis. Elevated levels of tumor necrosis factor alpha (TNF-alpha) have been reported to correlate with the development of transplant-related complications after bone marrow transplantation (BMT). In a recent phase I-II trial, oral administration of pentoxifylline (PTX), a xanthine derivative capable of downregulating TNF-alpha production in vitro, was reported to reduce morbidity and mortality in patients undergoing BMT. We conducted a prospective randomized trial of PTX therapy among 140 patients undergoing either allogeneic (n = 51) or autologous BMT (n = 89). Patients were randomized to receive (n = 70) or not receive (n = 70) oral PTX, 1,600 mg/d in four divided doses from day -8 until day + 100 post-BMT. The incidence of mucositis requiring morphine sulfate (MSO4) was similar in both groups (42.9%), with the mean number of days with MSO4 being 7.8 (SD = 3.4) in the PTX group versus 8.2 (SD = 3.4) in the control group (NS). The incidence of renal insufficiency was not affected by PTX administration (15.7% in the PTX group v 21.4% in the control group [NS]) and the highest serum creatinine value during the first 100 days post-BMT was 119 mumol/L (SD = 82.4) in the PTX group versus 103.9 mumol/L (SD = 57) in the control group (NS). The incidence of grade > or = 2 graft-versus-host disease was similar in each group (11/25 [44%] in the PTX group v 12/26 [46%] in the control group). No significant difference was observed in hematologic toxicity, transfusion requirements, duration of fever, and hepatic toxicity between the treatment groups. In conclusion, our study failed to show a prophylactic effect of PTX in transplant-related toxicities after BMT. On the basis of these findings, we cannot recommend that PTX be part of early mortality and morbidity prevention programs after BMT. Benzydamine was evaluated in patients with head and neck carcinoma for treatment of radiation-induced oral mucositis, a frequent complication of radiation therapy (RT) for which there is no predictable therapy or preventive treatment currently available.
                The safety and efficacy of 0.15% benzydamine oral rinse in preventing or decreasing erythema, ulceration, and pain associated with oral mucositis during RT were evaluated in a randomized, placebo-controlled trial conducted in patients with head and neck carcinoma. Subjects were to rinse with 15 mL for 2 minutes, 4-8 times daily before and during RT, and for 2 weeks after completion of RT; study evaluations were conducted before RT and routinely thereafter up to 3 weeks after RT.
                During conventional RT, regimens up to cumulative doses of 5000 centigrays (cGy) benzydamine (n = 69) significantly (P = 0.006) reduced erythema and ulceration by approximately 30% compared with the placebo (n = 76); greater than 33% of benzydamine subjects remained ulcer free compared with 18% of placebo subjects (P = 0.037), and benzydamine significantly delayed the use of systemic analgesics compared with placebo (P < 0.05). Benzydamine was not effective in subjects (n = 20) receiving accelerated RT doses (> or = 220 cGy/day). The incidence of adverse events between treatment groups was comparable without significant differences. Early discontinuation because of adverse events occurred in 6% of benzydamine subjects and 5% of placebo subjects, and there was 1 death (related to the primary diagnosis) in a placebo subject.
                Benzydamine oral rinse was effective, safe, and well tolerated for prophylactic treatment of radiation-induced oral mucositis.
                Copyright 2001 American Cancer Society. Mucositis occurs in almost all patients treated with radiotherapy for head and neck cancer. The aim of this multicenter, double-blind, prospective, randomized trial was to evaluate the clinical efficacy of an economically viable antimicrobial lozenge (bacitracin, clotrimazole, and gentamicin [BcoG]) in the alleviation of radiation-induced mucositis in patients with head and neck cancer.
                One hundred thirty-seven eligible patients were randomized to treatment with either antimicrobial lozenge (69 patients) or placebo lozenge (68 patients). The primary end point of the study was the time to development of severe mucositis from the start of radiotherapy. Secondary end points included severity and duration of mucositis, pain measurement, radiation therapy interruption, and quality of life. Mucositis was scored using a validated mucositis scoring system.
                Toxicity profiles were similar between the two arms of the study. The median time to development of severe mucositis from the start of radiotherapy was 3.61 weeks on BCoG and 3.96 weeks on placebo (P =.61). There were no statistically significant differences between the arms in the extent of severe mucositis as measured by physician, in oral toxicities as recorded by patients, or in radiotherapy delays.
                This study was conducted on the basis of a pilot study that demonstrated the BCoG lozenge to be tolerable and microbiologically efficacious. A validated mucositis scoring system was used. However, in this group of patients treated with conventional radiotherapy, the lozenge did not impact significantly on the severity of mucositis. Whether such a lozenge would be beneficial in treatment situations where rate of severe mucositis is higher (ie, in patients treated with unconventional fractionation or with concomitant chemotherapy) is unknown. nan To evaluate the efficacy of pure natural honey as prophylaxis against radiochemotherapy-induced mucositis, through clinical scoring of oral and oropharyngeal mucositis, and culturing of pathogenic oral and oropharyngeal microbes.
                The study was done in Assiut University Hospital, Egypt, between January 2005 and July 2006. Forty patients diagnosed with head and neck cancer were entered into the trial. Enrolled patients were randomised to either the treatment group, receiving concomitant chemotherapy and radiotherapy (with a significant area of directly visible oral and/or oropharyngeal mucosa included in the radiation fields) plus prior topical application of pure natural honey, or the control group, receiving concomitant chemotherapy and radiotherapy without honey. Patients were evaluated clinically every week to assess development of radiation mucositis. Aerobic cultures and candida colonisation assessment were undertaken, via oral and oropharyngeal swabs, prior to and at the completion of irradiation, and when infection was evident.
                In the treatment group, no patients developed grade four mucositis and only three patients (15 per cent) developed grade three mucositis. In the control group, 13 patients (65 per cent) developed grade three or four mucositis (p < 0.05). Candida colonisation was found in 15 per cent of the treatment group and 60 per cent of the control group, either during or after radiotherapy (p = 0.003). Positive cultures for aerobic pathogenic bacteria were observed in 15 per cent of the treatment group and 65 per cent of the control group, during or after radiotherapy (p = 0.007).
                This study shows that prophylactic use of pure natural honey was effective in reducing mucositis resulting from radiochemotherapy in patients with head and neck cancer. This pilot study evaluates the degree of side effects during high-dose chemotherapy (HD-VIC) plus autologous bone marrow transplant (HDCT) and its possible prevention by the cytoprotective thiol-derivate amifostine. Additionally, the in-patient medical costs of both treatment arms were compared. 40 patients with solid tumours were randomized to receive HD-VIC chemotherapy with or without amifostine (910 mg/m(2)at day 1-3) given as a short infusion prior to carboplatin and ifosfamide. Patients were stratified according to pretreatment. HDCT consisted of an 18 h infusion of carboplatin (500 mg/m(2/)d over 18 h), ifosfamide (4 g/m(2)/d over 4 h) and etoposide (500 mg/m(2)/d) all given for 3 consecutive days. All patients received prophylactic application of G-CSF (5 microg kg(-1)subcutaneously) to ameliorate neutropenia after treatment. Patients were monitored for nephrotoxicity, gastrointestinal side effects, haematopoietic recovery, as well as frequency of fever and infections. The median fall of the glomerular filtration rate (GFR) was 10% from baseline in the amifostine group (105 to 95 ml min(-1)) and 37% in the control patient group (107 to 67 ml min(-1)) (P< 0.01). Amifostine-treated patients revealed a less pronounced increase in albumin and low molecular weight protein urinary excretion. Stomatitis grade III/IV occurred in 25% without versus 0% of patients with amifostine (P = 0.01). Acute nausea/vomiting was frequently observed immediately during or after the application of amifostine despite intensive antiemetic prophylaxis consisting of 5-HT3-receptor antagonists/dexamethasone/trifluorpromazine. However, delayed emesis occurred more often in the control patients. Engraftment of neutrophil (> 500 microl(-1))and thrombocytes (> 25 000 microl(-1))were observed at days 9 versus 10 and 10 versus 12, respectively, both slightly in favour of the amifostine arm. In addition, a lower number of days with fever and a shortened duration of hospital stay were observed in the amifostine arm. The reduction of acute toxicity observed in the amifostine arm resulted in 30% savings in costs for supportive care (Euro 4396 versus Euro 3153 per patient). Taking into account the drug costs of amifostine, calculation of in-patient treatment costs from the start of chemotherapy to discharge revealed additional costs of Euro 540 per patient in the amifostine arm. This randomized pilot study indicates that both organ and haematotoxicity of HD-VIC chemotherapy can be ameliorated by the use of amifostine. Additionally, a nearly complete preservation of GFR was observed in amifostine-treated patients which may be advantageous if repetitive cycles of HDCT are planned. Larger randomized trials evaluating amifostine cytoprotection during high-dose chemotherapy are warranted. Misoprostol, a prostaglandin E(1) analog, is an effective radioprotector in animal studies. Based on this evidence, a prospective, randomized, placebo-controlled, double-blind study was conducted to determine if misoprostol protected the oral and pharyngeal mucosa of irradiated head and neck cancer patients from radiation mucositis. Postsurgical patients who had no detectable cancer and who were referred for postoperative irradiation were candidates for this study. Thirty-four Hines VA and 35 Loyola University patients were accrued (69 total) over a 2-year period. A misoprostol tablet (200 &mgr;g) or an identical placebo tablet was dissolved in water and administered as an oral rinse daily about 20 min before irradiation. Conventional fractionated radiotherapy, consisting of five weekly doses of 2 Gy day(minus sign1), was delivered. The degree of mucositis was scored on a scale from 0 (no mucositis) to 4. In the 17 patients randomly assigned to the misoprostol arm at the Hines VA, no advantage was seen compared to the 17 placebo-treated patients. However, there was significantly less mucositis (p < 0.01, analysis of variance) from weeks 3--6 in the 17 patients treated with misoprostol at Loyola compared to the 18 placebo-treated patients. Several problems in the study were identified at the VA, including adherence to the protocol design. Other problems such as adequate mucositis scoring, radiation scatter from fillings, and, in particular, adequate timing between misoprostol and irradiation were identified at both locations. Absorption studies in healthy volunteers showed significant plasma levels at 10 min after an oral rinse, suggesting that initial clinical trials should be confined to topical misoprostol until more is known regarding the effect of misoprostol on tumors. The results of this pilot study suggest that misoprotol may protect the oral and pharyngeal mucosa from radiation-induced mocositis if adequate time between topical administration and radiation is allowed. In an open study, the efficacy of povidone-iodine in the prophylaxis of mucositis during antineoplastic radiochemotherapy was determined. 40 patients were randomly assigned to a treatment or control group (each 20 patients). All patients received standard prophylaxis of mucositis with nystatin, dexpanthenol, rutoside and immunoglobulin. In addition, the patients of the treatment group performed 4 times daily rinsing with povidone-iodine, the control patients with sterile water. Clinical examination of the oral mucosa was performed weekly during the radiation period and up to 6 weeks after the end of therapy. Oral mucositis was observed in 14 patients of the treatment group (mean grading: 1.0) and in all 20 patients of the control group (mean grading: 3.0). The mean onset of mucositis was after 2.25 weeks in treatment patients and 1.5 weeks in control patients. The mean total duration of mucositis was 2.75 weeks in treatment patients and 9.25 weeks in control patients. The mean AUC values were 2.5 in treatment patients and 15.75 in control patients. All findings were statistically significantly different between the two groups. It is concluded that rinsing with povidone-iodine reduces the incidence, severity and duration of oral mucositis during antineoplastic radiochemotherapy. Radiation-induced mucositis is an early effect of head and neck radiotherapy. Mucositis can cause ulcers, and patients may experience pain and dysphasia which need treatment. The aim of this study is to evaluate the effect of pure natural honey on radiation induced mucositis.
                In this randomized single blind (examiner blind) clinical trial 40 patients with head and neck cancer requiring radiation to the oropharyngeal mucosa were randomly assigned to two groups. Twenty patients assigned to the study group received honey, while both the study and control groups received standard head and neck radiation therapy based on a standard protocol. In the study group patients were instructed to take 20 ml of honey 15 minutes before radiation therapy, then again at intervals of 15 minutes and six hours after radiation. In the control group patients were instructed to rinse with 20 ml of saline before and after radiation. Patients were evaluated weekly for progression of mucositis using the Oral Mucositis Assessing Scale (OMAS). Data were analyzed using the independent t-test, Mann-Whitney, and Friedman tests.
                A significant reduction in mucositis among honey-received patients compared with controls (p=0.000) occurred.
                Within the limits of this study the results showed the application of natural honey is effective in managing radiation induced mucositis.
                Natural honey is a product with rich nutritional qualities that could be a pleasant, simple, and economic modality for the management of radiation mucositis. Radiation-induced mucositis is an acute reaction of the mucosa of patients undergoing head and neck radiotherapy. It can have debilitating and dose-limiting consequences. There is no consensus on an accepted intervention that significantly reduces its severity. Misoprostol is a synthetic prostaglandin E1 analogue, with properties of a mucosal cytoprotectant. We designed a randomized, double-blind, placebo-controlled trial of misoprostol in patients with head and neck cancer. The aim of this study was to determine if topical misoprostol was effective in reducing the severity of radiation-induced mucositis in patients receiving radical dose radiotherapy. The effect of this intervention on a patient's general well-being was also investigated. The primary end-point of the study was the incidence of Radiation Therapy Oncology Group grade 3 mucositis. Between 1999 and 2002, 83 patients were recruited into the study at Westmead and Nepean Hospitals, Sydney. Forty-two patients were randomized to receive misoprostol and 41 to receive a placebo. Most patients received radiotherapy in the adjuvant setting (52 of the 83) and had either an oral cavity (42 of the 83) or an oropharyngeal (16 of the 83) cancer. We could not identify any significant difference in the incidence of severe mucositis based on whether patients were allocated to receive misoprostol or placebo. There was no significant difference in the mean area under the mucositis curve (13.2 vs 16.6; P = 0.1). Patients allocated to misoprostol did report slightly increased soreness (7.6 vs 6.9; P = 0.04) and a greater use of analgesics. However, this difference did not translate into a worse feeling of general well-being as measured by a simple visual analogue scale (5.8 vs 5.2; P = 0.3). In conclusion, we were unable to identify a reduction in radiation-induced mucositis in patients receiving misoprostol. There is a paucity of high-level evidence on potentially useful interventions and a continued need for new and innovative research, incorporating quality-of-life measurements, in patients experiencing radiation-induced mucositis. To evaluate the effect of indigowood root (Isatis indigotica Fort.) on acute mucositis induced by radiation.
                The objective severity of mucositis, anorexia, and swallowing difficulty were measured before and after the treatment.
                Patients with head and neck cancer receiving radiotherapy at Tian Sheng Memorial Hospital, Taiwan were recruited for this trial.
                Twenty (20) patients were randomized into two groups. Group 1 served as controls with only normal saline, and group 2 as the indigowood root (IR) group.
                Prophylactic application of IR consisted of gargling and then swallowing the IR preparation on the irradiated oral mucosa.
                Patients' characteristic distribution of gender, age, diagnosis, and mean radiation dose between the two arms were calculated by Fisher's exact test. We compared the mean of grade 1-4 mucositis, anorexia, difficulty in swallowing, and body weight change with the Mann-Whitney U test. p values less than 0.05 indicated statistical significance.
                The clinical trial showed that application of IR can reduce the severity of radiation mucositis (p = 0.01), anorexia (p = 0.002), and swallowing difficulty (p = 0.002). Although patients' resting days did not show a significant difference (p = 0.06), complete radiotherapy was done without rest for 4 of 11 patients in the IR group versus 2 of 9 in controls. Hemoglobin level between both groups showed no significant difference. Serum interleukin-6 was significantly lower in the IR group during the first, fifth, and seventh weeks.
                We confirmed that indigowood root has anti-inflammatory ability to reduce the mucosal damage caused by radiation. We postulate that indirubin may play a pharmaceutical role in improvement of radiation mucositis, anorexia, and difficulty in swallowing in our clinical trial. However, the exact mechanisms and pathways still need further analysis. Antimicrobial solutions are widely used in the nursing care of chemotherapy induced oral mucositis (OM). There is little evidence, however, supporting their use for reducing mucosal damage. In our study, 132 patients were randomized to use normal saline (n=65) or povidone-iodine diluted 1:100 (n=67) mouthwashes for OM prophylaxis and treatment after high-dose chemotherapy comprising BEAM or HD-L-PAM followed by autologous peripheral stem cell transplantation. The study groups were well balanced in respect of age, sex, chemotherapy and the number of CD34+ cells in the graft. No significant difference was found between the groups in respect of OM characteristics, fever of unknown origin (FUO) and other infections. The antimicrobial solution was less tolerable for patients. OM occurred significantly more often in females than in males (86% vs 60%, P=0.0016) and was worse and of longer duration. The mechanical effect of mouthwashes might have a certain importance in FUO prevention. When indicating oral rinses, the patient's individual preference and tolerance of solutions offered should be considered. The effect of parenteral glutamine dipeptide (Gln) supplementation on neutrophil phagocytosis, superoxide anion generation (SAG), prevention of chemotherapy-induced side-effects and cost-effectiveness was examined in a pilot study of acute myeloid leukaemia (AML) patients receiving chemotherapy. Sixteen AML patients were randomized to receive intravenous supplementation with Gln (30 g/day) or an equivalent quantity (25 g/day) of a standard amino acid mixture (control) on days 1 - 5 of chemotherapy. Complete blood count was evaluated twice a week until hospital discharge, and neutrophil phagocytosis and SAG were measured when absolute neutrophil count reached > 500 /microl. Patients were observed for development of infection, mucositis and diarrhoea. In Gln-treated patients, the percentage of neutrophil phagocytosis and the SAG levels were significantly higher than in control patients (20.5 +/- 6.0% and 18.9 +/- 2.9 nmol/10(6) neutrophils per 10 min, respectively). The Gln-treated patients lost significantly less weight, tended to have shorter in-patient duration and had less severe oral mucositis than controls. This pilot study provides preliminary indication that parenteral Gln supplementation enhances neutrophil phagocytic function, maintains nutritional status and is cost effective. Parenteral Gln may also prevent oral mucositis, although further studies involving more patients need to be undertaken to confirm this and the other results. This study sought to determine whether sucralfate prophylaxis during a course of high dose radiation therapy (RT) for head and neck cancer decreases acute side effects.
                Patients receiving curative intent RT for advanced head and neck cancers participated in a single institution double-blind randomized trial comparing sucralfate to placebo. Patients were stratified according to fractionation, use of concurrent chemotherapy, Karnofsky performance status (KPS), age, and pretreatment presence of a feeding gastrostomy. Patients were prospectively evaluated during weekly treatment checks, and analyzed with regard to time (measured in terms of dose) until development of the following: weight loss, mucositis, pain, nutritional intake, and need for a treatment break. After completion of RT, time until healing was similarly compared.
                Fifty-two patients received sucralfate and 50 received placebo. The mean (+/-SD) prescribed dose was 69 +/- 7 Gy. Sixty-nine patients received BID fractionation and 27 received concurrent chemotherapy. No difference was detected in any outcome measure in the direct comparison between the two groups. On multivariate analysis, weight loss >5% or >10% occurred more frequently in patients receiving chemotherapy (p < 0.01 and p = 0.05, respectively). Grade 3 mucositis was more common in patients receiving chemotherapy (p = 0.05) or BID fractionation (p = 0.04) or having a poor KPS (p = 0.02). Interval to healing was not associated with any of the pretreatment- or treatment-related factors. Sucralfate did not result in any additional toxicity.
                Prophylactic treatment with sucralfate during high-dose head and neck RT did not decrease acute treatment side effects. Other modalities should be investigated.
                Copyright 1999 John Wiley & Sons, Inc. Head Neck 21: 760-766, 1999. Use of the low-energy helium-neon laser (LEL) appears to be a simple atraumatic technique for the prevention and treatment of mucositis of various origins. Preliminary findings, and significant results obtained for chemotherapy-induced mucositis in a previous phase III study, prompted a randomized multicenter double-blind trial to evaluate LEL in the prevention of acute radiation-induced stomatitis. Irradiation by LEL corresponds to local application of a high-photon-density monochromatic light source. Activation of epithelial healing for LEL-treated surfaces, the most commonly recognized effect, has been confirmed by numerous in vitro studies. The mechanism of action at a molecular and enzymatic level is presently being studied. From September 1994 to March 1998, 30 patients were randomized. Technical specification: 60 mW (25 mW at Reims, 1 patient), He-Ne, wavelength 632.8 nm. The trial was open to patients with carcinoma of the oropharynx, hypopharynx and oral cavity, treated by radiotherapy alone (65 Gy at a rate of 2 Gy/fraction, 5 fractions per week) without prior surgery or concomitant chemotherapy. The malignant tumor had to be located outside the tested laser application areas (9 points): posterior third of the internal surfaces of the cheeks, soft palate and anterior tonsillar pillars. Patients were randomized to LEL or placebo light treatment, starting on the first day of radiotherapy and before each session. The treatment time (t) for each application point was given by the equation : t(s)= energy (J/cm2) x surface (cm2)/Power (W). Objective assessment of the degree of mucositis was recorded weekly by a physician blinded to the type of treatment, using the WHO scale for grading of mucositis and a segmented visual analogue scale for pain evaluation. Protocol feasibility and compliance were excellent. Grade 3 mucositis occured with a frequency of 35.2% without LEL and of 7.6% with LEL (P<0.01). The frequency of "severe pain" (grade 3) was 23.8% without LEL, falling to 1.9% with LEL (P<0.05). Pain relief was significantly reduced throughout the treatment period (weeks 2-7). LEL therapy is capable of reducing the severity and duration of oral mucositis associated with radiation therapy. In addition, there is a tremendous potential for using LEL in combined treatment protocols utilizing concomitant chemotherapy and radiotherapy. To compare granulocyte-macrophage colony-stimulating factor (GM-CSF) mouthwashes with sucralfate mouthwashes in the prevention of radiation-induced mucositis.
                Forty patients with radically operated head-and-neck cancer were randomly allocated to use either GM-CSF (n = 21) or sucralfate (n = 19) mouthwashes during postoperative radiotherapy (RT). All patients received conventionally fractionated RT to a total dose of 50-60 Gy in 2-Gy daily fractions during 5-6 weeks to the primary site and regional lymphatics. A minimum of 50% of the oral cavity and oropharyngeal mucosa was included in the clinical target volume. GM-CSF mouthwashes consisted of 37.5 microg GM-CSF and sucralfate mouthwashes of 1.0 g of sucralfate distilled in water. Both washes were used 4 times daily, beginning after the first week of RT and continued to the end of the RT course. Symptoms related to radiation mucositis and body weight, serum prealbumin level, and blood cell counts were monitored weekly.
                Oral mucositis tended to be less severe in the GM-CSF group (p = 0.072). Complete (n = 1) or partial (n = 4) healing of mucositis occurred during the RT course in 5 patients (24%) in the GM-CSF group and in none of the patients in the sucralfate group (p = 0.049). Patients who received GM-CSF had less mucosal pain (p = 0.058) and were less often prescribed opioids for pain (p = 0.042). Three patients in the sucralfate group needed hospitalization for mucositis during RT compared with none in the GM-CSF group. Four patients (21%) in the sucralfate group and none in the GM-CSF group required an interruption in the RT course (p = 0.042). No significant differences in weight, prealbumin level, or blood cell count were found between the groups, and both mouthwashes were well tolerated.
                GM-CSF mouthwashes may be moderately more effective than sucralfate mouthwashes in preventing radiation-induced mucositis and mucositis-related pain, and their use may lead to less frequent RT course interruptions from mucositis. The present findings need to be confirmed before adopting GM-CSF mouthwashes in routine clinical use. Experimental and clinical data suggest a reduction of radiation-induced acute toxicity by amifostine (A). We investigated this issue in a randomized trial comparing radiochemotherapy (RT + CT) versus radiochemotherapy plus amifostine (RC + CT + A) in patients with head and neck cancer.
                56 patients with oro-/hypopharynx or larynx cancer (T1-2 N1-2 G3, T3-4 N0-2 G1-3) were randomized to receive RC + CT alone or RC + CT + A. Patients were irradiated up to 60 Gy (R0) or 70 Gy (R1/2) and received chemotherapy (70 mg/m(2) carboplatin, day 1-5 in week 1 and 5 of radiotherapy). 250 mg amifostine were applied daily before each radiotherapy session. Acute toxicity was evaluated according to the Common Toxicity Criteria (CTC). As for acute xerostomia, patients with laryngeal cancer were excluded from evaluation.
                50 patients were evaluable (25 patients in the RC + CT, 25 patients in the RC + CT + A group). Clinical characteristics were well balanced in both treatment groups. Amifostine provided reduction in acute xerostomia and mucositis but had no obvious influence on Karnofsky performance status, body weight, cutaneous side effects, and alopecia. The differences between both groups were statistically significant for acute xerostomia and nonsignificant, but with a trend for mucositis.
                According to our results, there is a radioprotective effect on salivary glands and a potential effect on oral mucosa by amifostine in postoperative radiotherapy combined with carboplatin. To improve the radio- and chemoprotective effects of amifostine in clinical practice, the application of a higher dose (> 250 mg) seems to be necessary. Mucositis is still a leading side effect of high dose chemotherapy and irradiation delivered in autologous and allogeneic bone marrow transplantation. In this double blind randomised study, we tested the efficacy of sucralfate for the prevention of mucositis induced by such conditioning treatments. Treatment was started one day before conditioning regimen and patients were prospectively evaluated. The main endpoint was severe mucositis that was more frequent in the placebo group than in the sucralfate group (47% vs. 29%, P = 0.07). This trend was confirmed after adjustment on total body irradiation (TBI) (P = 0.06), the sole stratification parameter. Interestingly, patients receiving sucralfate showed a significant reduction of diarrhoea (25%) vs. 53%, P = 0.005). Overall, the preventive administration of sucralfate appears to be an effective procedure to diminish the occurrence of severe oral and intestinal mucositis in patients treated by high dose chemotherapy alone or combined with TBI before bone marrow transplantation. Between February 1986 and November 1989, 166 patients who were candidates for a bone marrow transplantation entered a randomised controlled clinical trial to compare limited oral hygiene care (LIM) and intensive oral hygiene care (INT) in the prevention of mucositis. Randomisation was stratified on the initial oral status (good vs. bad IOS). Intensive oral hygiene care included an initial treatment of dental lesions and tooth and gum brushing during aplasia. Limited oral hygiene care excluded preventive dental treatment and gingival and tooth brushing. Mucositis was classified as absent, mild, moderate or severe, according to the clinical aspects of the different sites in the mouth and to two scales of pain evaluation. Of the 150 evaluable patients (75 in each group), 134 developed moderate/severe mucositis (64 in the INT group and 70 in the LIM group) (log-rank test P < 0.02). The superiority of intensive oral care was observed both in patients with and without total body irradiation (TBI) and in patients with a good or bad IOS; the observed risk of mucositis was reduced by 70% in each of these four subgroups. Duration of moderate/severe mucositis was, although not significantly, lower in the INT group (17 days, S.D. = 12) than in the LIM group (19 days, S.D. = 13). The median time of mucositis occurrence was 11 days in the INT group and 9 days in the LIM group. Contrary to a widespread belief, the percentage of documented septicaemia was not higher in patients who underwent intensive oral care. We conclude that, although statistically significant, the superiority of intensive oral hygiene care is not clinically impressive.(ABSTRACT TRUNCATED AT 250 WORDS) We investigated the clinical effects of low-power laser therapy (LPLT) on prevention and reduction of severity of conditioning-induced oral mucositis (OM) for hematopoietic stem cell transplantation (HSCT). We randomized 38 patients who underwent autologous (AT) or allogeneic (AL) HSCT. A diode InGaAlP was used, emitting light at 660 nm, 50 mW, and 4 J/cm2, measured at the fiberoptic end with 0.196 cm2 of section area. The evaluation of OM was done using the Oral Mucositis Assessment Scale (OMAS) and the World Health Organization (WHO) scale. In the LPLT group, 94.7% of patients had an OM grade (WHO) lower than or equal to grade 2, including 63.2% with grade 0 and 1, whereas in the controls group, 31.5% of patients had an OM grade lower than or equal to grade 2 (P < .001). Remarkably, the hazard ratio (HR) for grades 2, 3, and 4 OM was 0.41 (range, 0.22-0.75; P = .002) and for grades 3 and 4 it was 0.07 (range, 0.11-0.53; P < .001). Using OMAS by the calculation of ulcerous area, 5.3% of the laser group presented with ulcers of 9.1 cm2 to 18 cm2, whereas 73.6% of the control group presented with ulcers from 9.1 cm2 to 18 cm2 (P = .003). Our results indicate that the use of upfront LPLT in patients who have undergone HSCT is a powerful instrument in reducing the incidence of OM and is now standard in our center. A randomized control trial study was carried out to evaluate the effect of allopurinol mouth wash on stomatitis induced by chemotherapy in gynecologic patients. Chemotherapeutics used consisted of 5-FU+CDDP (PF) given to 10 patients and vincristine and actinomycin-D+cyclophosphamide (VAC) given to 5. Allopurinol mouth wash was prepared for patients to rinse their mouth with the solution 4-5 times daily before and after treatment with anti-cancer drugs. The Japan Society For Cancer Therapy's criteria for stomatitis were used. In the control group, stomatitis occurred in 9 of the 10 patients receiving PF therapy and in all of the 5 receiving VAC. In contrast, stomatitis was observed in only 2 of the 10 patients receiving PF therapy and 2 of the 5 VAC in the allopurinol-treated group. Allopurinol mouth wash showed a marked effect on stomatitis induced by chemotherapy. A randomized, double-blind, placebo-controlled trial was conducted to evaluate the effectiveness of a sucralfate mouthwash in preventing and alleviating oral mucositis induced by 5-fluorouracil (5FU). A total of 81 patients with colorectal cancer were enrolled. Patients were studied during their first cycle of chemotherapy with 5FU and leucovorin (LV) daily for 5 days every 4 weeks (Mayo Clinic schedule). Patients were randomly allocated to receive either a sucralfate suspension or a placebo suspension that was identical in appearance. Patients were instructed to use the suspension as a mouthwash four times daily from the beginning of the chemotherapy cycle. All patients received oral cryotherapy. Patients graded the severity of their own symptoms on a daily basis, and this was the primary outcome measure. There was no difference in the frequency or severity of oral mucositis between the sucralfate- and the placebo-treated group. Some mucositis was reported by 79% of the patient group. Assessment of mucositis by trial staff underestimated the incidence of this problem. Results of this trial do not support the hypothesis that a sucralfate mouthwash can prevent or alleviate oral mucositis induced by 5FU. Patient reporting of mucositis is a more sensitive instrument for assessment of mucositis than review by medical staff. Mucositis is a significant dose-limiting toxicity associated with fluorouracil (5FU), particularly when it is combined with leucovorin. We hypothesized that oral cryotherapy would cause local vasoconstriction and would temporarily decrease blood flow to the oral mucous membranes. If cryotherapy were used during the time of peak serum 5FU levels, then the oral mucous membranes would have less exposure to 5FU and thus develop less mucositis. To test this hypothesis, 95 patients scheduled to receive their first cycle of 5FU plus leucovorin were randomized to have oral cryotherapy at the time of chemotherapy administration or to serve as a control group. Subsequent mucositis was significantly reduced in the group assigned to receive cryotherapy as judged by the attending physicians (P = .0002) and by the patients themselves (P = .0001). We now routinely recommend this cryotherapy procedure for our patients receiving daily bolus 5FU plus leucovorin. Patients with head and neck cancer were randomized in a double-blind manner to receive 40 mg/day prednisone (n = 32) or placebo (n = 34). The prescribed daily tumour dose was 1.6 Gy twice daily with an interfraction interval of > or =6 h. Treatment interruptions were at the discretion of the radiation oncologists. The primary study end-point was the total duration of treatment. A mean 4.4 day reduction was observed in the total elapsed treatment duration for the prednisone arm, 34.3 versus 29.9 days (P = 0.013), which paralleled a significantly lower median total tumour and biologically effective dose (BED) Gy10 in this arm. A trend favouring shorter treatment interruptions in the prednisone arm was also found, but not a reduction in the intensity or duration of mucositis. To determine the effect of oral zinc sulphate supplementation on radiation-induced oropharyngeal mucositis in patients with head-and-neck cancer.
                Thirty patients with head-and-neck cancer were randomly assigned to receive either zinc sulfate or placebo. Primary tumors were localized in the larynx in 14 patients, in the nasopharynx in 4, in the oral cavity in 4, in a salivary gland in 1, in the maxillary sinus in 1, in neck nodes (lymphoma presenting primarily) in 3 and in neck metastases from an unknown primary in 3. In the placebo group, 3 patients were excluded; 1 patient died during treatment, 1 left the study, and 1 did not come to the 6 week control visit. The patients were treated with telecobalt radiotherapy at conventional fractionation (2 Gy/fraction, five fractions weekly, for 20-35 fractions within 4-7 weeks). The median radiation dose was 6400 cGy (4000-7000 cGy). Oral mucositis was assessed by two independent physicians, experts in radiation oncology, using the Radiation Therapy Oncology Group Acute Radiation Morbidity Scoring criteria.
                In the zinc sulfate group, Grade 3-4 mucositis was not detected in any patient; Grade 0 mucositis was detected in 2, and Grade 1 in 8, and Grade 2 in 5 patients. In the placebo group, Grade 2 mucositis was detected in 4 and Grade 3 in 8 patients. We observed that the degree of mucositis in the patients in the zinc sulfate group was significantly lower than that in the placebo group (p < 0.05). Confluent mucositis developed earlier in the placebo group than in the zinc sulfate group after the onset of treatment (p < 0.05) and started to improve sooner in the zinc sulfate group than in the placebo group (p < 0.05).
                Zinc sulfate is beneficial in decreasing the severity of radiation-induced mucositis and oral discomfort. These results should be confirmed by additional evaluation in randomized studies with a larger number of patients. We have studied whether mouth-swishing with sucralfate, a well-known gastric mucosal protective agent, may be used as prophylaxis against chemotherapy-induced stomatitis. Using radioactively labelled sucralfate we found that 20-30% was still bound to the oral mucosal lining 2 1/2 h after mouth-swishing. Forty patients receiving cisplatin and continuous infusion with 5-fluorouracil (5-FU) for 5 days entered a double-blind placebo-controlled cross-over study. Among 23 evaluable patients a significant reduction (p = 0.04) in an objective score of edema, erythema, erosion and ulcerations was seen during treatment with sucralfate. Patient preference favored sucralfate, but this preference failed to reach statistical significance (p = 0.06). Seven patients were inevaluable for reasons not associated with the study treatment. However, ten patients did not complete the study since the swishing procedure aggravated chemotherapy-induced nausea. An equal rate of non-compliance was seen with sucralfate and placebo. To overcome this problem, the oral medication should have a neutral taste, the solution should not be swallowed after the swishing, which should not be started until the nausea had ceased. Preliminary studies in allogeneic BMT suggest that recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) is well tolerated. This is a prospective, multicenter, randomized, double-blind, placebo-controlled trial. Yeast-derived rhGM-CSF 250 micrograms/m2/day or placebo was administered by 4-hour i.v. infusion starting on the day of marrow infusion (day 0) to day 20. All patients received HLA-identical sibling marrow and cyclosporine and prednisone for GVHD prophylaxis. Fifty three patients received rhGM-CSF and 56 received placebo. Comparison of demographics revealed no differences. The time to achieve an absolute neutrophil count of > 0.5 x 10(9) cells/l was shortened in rhGM-CSF treated patients (day 13 vs. 17, P = 0.0001). The incidences of grade III-IV mucositis and infection were significantly reduced (P = 0.005, P = 0.001, respectively) and duration of hospitalization was modestly shortened by 1 day (P = 0.02) in rhGM-CSF treated patients. No differences in platelet recovery, erythrocyte recovery, incidence of veno-occlusive disease, GVHD severity, relapse or survival were observed. In conclusion, rhGM-CSF is well tolerated and reduces post-transplant morbidity in patients undergoing HLA-identical allogeneic BMT. To observe the therapeutic effect of shenqi fanghou recipe (SFR) in preventing and treating radiation injury in patients with head and neck tumor.
                One hundred and forty patients with head and neck tumor, including nasopharyngeal carcinoma, carcinoma of tonsil or tongue, were randomly divided into 2 groups, 70 patients in the observed group were given modified SFR as adjuvant to radiotherapy, while 70 patients in the control group were treated with radiotherapy alone. The radiation reactions during radiotherapy and the condition of late stage radiation injury radiotherapy in patients in the 2 groups were observed.
                The degree of oropharyngeal mucosa reaction, dryness in mouth and radiation dermatitis in cervical region in the observed group was milder than those in the control group, and the radiation injury induced late stage sequelae, such as the degree of mouth-opening was better and the cervical muscular sclerosis was better in the observed group than in the control group, showing significant difference (P < 0.01).
                SFR has definite effect in preventing and treating radiation reaction and late stage radiation injury in patients with head and neck tumor. To characterize the efficacy and safety of palifermin in reducing the incidence of oral mucositis (OM) and diarrhea when administered to patients with metastatic colorectal cancer (CRC) receiving fluorouracil/leucovorin (FU/LV) chemotherapy.
                Patients (N = 64) were randomly assigned to receive either placebo or palifermin (40 microg/kg for 3 consecutive days) before each of two consecutive cycles of chemotherapy with FU/LV. The incidence of OM and diarrhea, safety, disease progression, and survival were evaluated.
                Thirty-six patients received placebo and 28 patients received palifermin. The incidence of WHO grade 2 or higher OM was lower in patients who received palifermin compared with placebo (29% v 61% in cycle 1; 11% v 47% in cycle 2). FU dose reductions in the second chemotherapy cycle were more frequent in the placebo group (31%) than in the palifermin group (14%). Investigators reported lower mucositis scores and patients reported less severe symptoms with palifermin. There were no statistically significant differences in the incidence or severity of diarrhea or in overall survival between the groups. Overall, palifermin was safe and well tolerated.
                Palifermin administered at the indicated dosing regimen (40 microg/kg for 3 consecutive days) before chemotherapy was well tolerated and resulted in a statistically significant and clinically meaningful reduction in the incidence of WHO grade 2 or higher OM in patients with metastatic CRC. This study assessed the use of low-energy laser in the prevention or reduction of the severity of oral mucositis.
                A randomized clinical trial was carried out. Patients from 3 to 18 years of age treated with chemotherapy or hematopoietic stem-cell transplantation between May, 2003 and February, 2005 were eligible. The intervention group received laser application for 5 days following the start of chemotherapy. The grade of oral mucositis was assessed by the WHO per NCI-CTC common toxicity criteria and the assessments were made on days 1, 8 and 15 by a trained examiner blind to the intervention.
                Sixty patients were evaluable for analysis; thirty-nine (65%) were males, 35 (58%) patients had a diagnosis of leukemia or lymphoma, and 25 (42%) had solid tumors. The mean age was 8.7 +/- 4.3 years. Twenty-nine patients were randomized in the laser group and 31 in the control group. On day 1, no patients presented with mucositis. On day 8, of 20 patients (36%) who developed mucositis, 13 of them were from the laser group and 7 from the control group. On day 15, of 24 patients (41%) who developed mucositis, 13 of them were from the laser group and 11 from the control group. There was no significant difference between groups concerning the grades of mucositis on day 8 (P = 0.234) or on day 15 (P = 0.208).
                This study showed no evidence of benefit from the prophylactic use of low-energy laser in children and adolescents with cancer treated with chemotherapy when optimal dental and oral care was provided. We evaluated sucralfate, well-known in the treatment of gastric ulcers, in relation to its possible reduction of radiation-induced acute complications in the treatment of head and neck cancers.
                One hundred two patients were randomized in a double-blind placebo-controlled prospective setting. All patients were treated to a minimum dose of 55 Gy in 5 weeks. Oral intake of sucralfate was started at the beginning of radiotherapy and continued during the whole treatment at a dose of 1 g six times a day. All patients were scored according to a scoring system developed in our department. Weight was checked once a week.
                Comparing the time course of the mean scores for subjective intolerance, mucositis, dysphagia, dermatitis and nausea, no statistically significant differences between the two treatment arms (sucralfate, n = 38; placebo, n = 45) were observed. The mean weight loss in the sucralfate arm was 1.6 +/- 3.4 kg while it was 1.3 +/- 2.0 kg in the placebo arm. Apart from gastrointestinal upset, the administration of sucralfate did not cause any side-effects.
                This trial produced no clinical evidence indicating that the oral intake of sucralfate reduces the acute radiation-induced side-effects. Therefore, we do not recommend the prophylactic use of sucralfate in patients with head and neck cancer treated by radiotherapy. Pilocarpine hydrochloride has been reported to increase salivation and decrease oral mucositis in patients receiving head and neck radiotherapy, but there is only one report of its use in a cancer chemotherapy patient population. This prospective, double-blinded, randomized, placebo-controlled trial was undertaken to determine the efficacy of pilocarpine for the moderation of oral mucositis during autologous blood stem cell transplantation. Subjects were randomized to receive a 5 mg tablet of pilocarpine, or a placebo, during and following chemotherapy. Subjects were seen every other day and evaluated for gingival, oral, and oropharyngeal mucositis; nutrition; oral hygiene; eating; speaking; sleeping; pain at rest and/or with swallowing; and mouth dryness. We recorded the mean and highest scores and duration of problems, along with white blood cell counts and differentials, and the use of systemic narcotics for oral mucosal pain. We enrolled and randomized 36 subjects, and there were no statistically or clinically significant differences for the primary outcome of severity of mucositis and no clinically significant differences in any of the other outcome measures. Pilocarpine has no benefit for the moderation of the incidence, severity, or duration of mucositis in patients receiving autologous blood stem cell transplantation. A randomised trial was undertaken to compare the effect of three oral care protocols in delaying the onset of stomatitis and reducing oral injury in nasopharyngeal cancer patients undergoing radiotherapy, 30 eligible patients with a mean age of 56.2 years were recruited and evenly allocated to one of the three groups using a randomly permuted blocks method. Patients allocated to group E1 and group E2 were given the same instructions on oral care at 1 day, and 1 week before radiotherapy, respectively, while those allocated to the control group were given no instructions. We use the Oral Assessment Guide to assess the oral physical conditions of these patients daily. Our findings revealed that the patients in the E2 group not only had later onset of stomatitis than those in the control and the E1 groups, but also had lesser degree of oral injury measured by the overall assessment score. We thereby recommend the use of the E2 protocol for delaying the onset of stomatitis and reducing oral injury in nasopharyngeal cancer patients undergoing radiotherapy. Radiotherapy is the usual mode of treatment for unresectable head and neck cancer. To improve cure rates, extend survival, and reduce morbidity, we use accelerated hyperfractionation radiotherapy and an adjuvant drug to inhibit prostaglandin synthesis. In this study, 19 patients received 300 rad/day of radiotherapy in two equally divided doses to a total dose averaging 6,200 rad. Either indomethacin, 25 mg, or placebo was given four times a day in a double-blind fashion during therapy. Radiation mucositis was graded as 0 to 4+; pain, nutritional status, and tumor status were monitored daily and recorded biweekly. Evaluation of the data showed delayed mucositis in the experimental group for grades 1 to 3, with a significant difference at grade 3 compared with controls. The significance of a long-term comparison of cure rates would be doubtful considering the heterogeneity of the primary sites and regional disease in this group coupled with the small size of our study. The present study was done to assess the effect of three alcohol-free mouthwashes on radiation-induced oral mucositis in patients with head and neck malignancies.
                Eighty patients with head and neck malignancies, scheduled to undergo curative radiotherapy, were randomly assigned to receive one of the three alcohol-free test mouthwashes (0.12% chlorhexidine, 1% povidone-iodine, or salt/soda) or a control. The patients were instructed to rinse with 10 ml of the mouthwash, twice a day, for a period of 6 weeks. Mucositis was assessed at baseline and at weekly intervals during radiation therapy, using the World Health Organization criteria for grading of mucositis. The baseline demography of the four groups was matched for age, sex, stage of cancer, and whether the patient had cancer of oral or extraoral regions. A post hoc test for repeated measures was used to find the difference of mean mucositis scores between the groups at various week intervals.
                Among the 76 patients who completed the study, patients in the povidone-iodine group had significantly lower mucositis scores when compared to the control group from the first week of radiotherapy. Their scores were also significantly lower when compared to the salt/soda and chlorhexidine groups from the fourth and fifth week, respectively, after radiotherapy.
                This study demonstrates that use of alcohol-free povidone-iodine mouthwash can reduce the severity and delay the onset of oral mucositis due to antineoplastic radiotherapy. We evaluated the efficacy of topically applied human recombinant epidermal growth factor (rhEGF) for the treatment of oral mucositis induced by radiotherapy (RT), with or without chemotherapy, in patients with head and neck cancer.
                Patients receiving definitive chemoradiotherapy, definitive RT, or postoperative RT to the oral cavity or oropharynx were recruited from 6 institutions and enrolled in a randomized, double-blind, placebo-controlled phase 2 trial. Patients were assigned to a placebo group or to 1 of 3 EGF-treatment groups (10, 50, or 100 microg/mL doses, delivered in a spray, twice daily). The grade of mucositis was evaluated using the Radiation Therapy Oncology Group (RTOG) scoring criteria. Responders to EGF were defined as having an RTOG grade of 2 or lower at the fourth- or fifth-week examinations during RT, but an enduring RTOG grade 2 for 2 weeks was an exception.
                Of the 113 patients included in the study, 28 received placebo and 29 received EGF at 10 microg/mL, 29 at 50 microg/mL, and 27 at 100 microg/mL. EGF significantly reduced the incidence of severe oral mucositis at the primary endpoint (a 64% response was observed with 50 microg/mL EGF vs a 37% response in the control group; P = .0246).
                The EGF oral spray may have potential benefit for oral mucositis in patients undergoing RT for head and neck cancer. Phase 3 studies are ongoing to confirm these results. Oral mucositis (OM) is a significant early complication of hematopoietic cell transplantation (HCT). This phase III randomized double-blind placebo-controlled study was designed to compare the ability of 2 different low level GaAlAs diode lasers (650 nm and 780 nm) to prevent oral mucositis in HCT patients conditioned with chemotherapy or chemoradiotherapy.
                Seventy patients were enrolled and randomized into 1 of 3 treatment groups: 650 nm laser, 780 nm laser or placebo. All active laser treatment patients received daily direct laser treatment to the lower labial mucosa, right and left buccal mucosa, lateral and ventral surfaces of the tongue, and floor of mouth with energy densities of 2 J/cm2. Study treatment began on the first day of conditioning and continued through day +2 post HCT. Mucositis and oral pain was measured on days 0, 4, 7, 11, 14, 18, and 21 post HCT.
                The 650 nm wavelength reduced the severity of oral mucositis and pain scores. Low level laser therapy was well-tolerated and no adverse events were noted.
                While these results are encouraging, further study is needed to truly establish the efficacy of this mucositis prevention strategy. Future research needs to determine the effects of modification of laser parameters (e.g., wavelength, fluence, repetition rate of energy delivery, etc.) on the effectiveness of LLE laser to prevent OM. To determine whether a chlorhexidine mouthwash could alleviate radiation-induced oral mucositis.
                Patients scheduled to receive radiation therapy to include greater than one third of the oral cavity mucosa were selected for study. Following stratification, they were randomized in a double-blind manner to receive a chlorhexidine mouthwash or a placebo mouthwash. Both groups were then similarly evaluated for mucositis and mouthwash toxicity.
                Twenty-five patients were randomized to receive the chlorhexidine mouthwash, while 27 received the placebo mouthwash. Treatment arms were well balanced. There was a trend for more mucositis and there was substantially more toxicity (eg, mouthwash-induced discomfort, taste alteration, and teeth staining) on the chlorhexidine arm.
                In contrast to the prestudy hypothesis that a chlorhexidine mouthwash might provide benefit for patients receiving radiation therapy to the oral mucosa, this study provides strong evidence suggesting that a chlorhexidine mouthwash is detrimental in this clinical situation. With the progression of radiotherapy techniques, the 5-year overall survival rate of nasopharyngeal carcinoma (NPC) patients has increased obviously. As the survival time prolonged, more and more attention was paid to various radiation sequelae and the quality of life of the patients. This study was to explore the role of individual dental stent in sparing normal oral tissues for primary NPC patients in radiotherapy by pushing the tongue and a part of oral mucous membrane away from the radiation fields.
                Irradiation dose and volume of the tongue of a NPC patient before and after wearing dental stent was evaluated. A total of 43 patients were randomized into 2 groups: 19 in trial group and 24 in control group. Trial group wore dental stent during radiotherapy, while control group did not. Patients' weight, taste, oral mucous reaction, and tongue mucous reaction before radiotherapy and every week during radiotherapy were examined.
                Dosimetric analysis proved that the irradiation dose and volume of the tongue decreased obviously in trial group. The occurrence rate of grade 1-2 mucositis of the oral cavity was higher in trial group than in control group (73.68% vs. 62.50%), but the occurrence rate of grade 3-4 mucositis was lower in trial group than in control group (26.32% vs. 37.50%, P=0.470). By the completion of radiotherapy, 4 (21.05%) patients in trial group and 19 (79.17%) in control group suffered from taste dysfunction (P<0.001).
                Individual dental stent is useful in sparing the oral mucous membrane and preserving taste for primary NPC patients in radiotherapy. In view of the good results obtained with benzydamine against oral radio-chemomucositis in a previous trial, a double-blind/placebo study was undertaken in order to ascertain the possible oral histoprotective effect of benzydamine mouthwash during the intra-arterial polychemotherapy and/or radiotherapy for neoplasms of the head and neck. Statistical comparison of the results obtained in these two groups, treated with benzydamine and placebo mouthwash, revealed a marked difference in the clinical evolution of iatrogenic tissue damage. The benzydamine topical application was more effective than placebo in the control of mucositis symptoms and signs produced by radiotherapy and/or intra-arterial antineoplastic chemotherapy. Sixty patients with breast cancer were randomly assigned to oral glutamine or placebo pre-neoadjuvant chemotherapy (CEF regimen).
                Oral glutamine supplementation was continued for at least 12 days. Patients kept a daily record of diarrhea and stomatitis. The plasma glutamine level, intestinal permeability (lactulose-mannitol test), and tumor size were analyzed. The expression of Ki-67 and PCNA antigens in breast carcinoma was assessed.
                The plasma glutamine level was significantly higher in the glutamine group than in the placebo group (420.39 +/- 52.39 mmol/L vs 309.76 +/- 42.34 mmol/L, P < 0.05). After one cycle of chemotherapy, the lactulose-mannitol ratio was higher in the placebo group than in the glutamine group (0.0630 +/- 0.0091 vs 0.0471 +/- 0.0094, P < 0.05). No differences were observed in the grades of stomatitis and diarrhea, in the changes in tumor size, and in the expression of Ki-67 and PCNA antigens between the two groups.
                Prophylactic oral glutamine could ameliorate the neoadjuvant chemotherapy-induced increase in intestinal permeability, but had no significant positive clinical effect on stomatitis and diarrhea and did not interfere with the antitumor effect of chemotherapy. The properties of saliva led us to hypothesize that the salivary flow increase induced by gum chewing might protect the oral mucosa from lesions due to cancer chemotherapy. We conducted a multicenter randomized trial to evaluate the efficacy of chewing gum in preventing oral mucositis in 145 children receiving chemotherapy regimens expected to induce WHO grade 3-4 oral mucositis in at least 30% of patients. Patients were allocated at random to standard oral care with or without 5 gum pieces per day. No overall reduction in severe oral mucositis occurred in the gum arm (51%) compared with the standard arm (44%). VIDE, COPADM, and multidrug intensive chemotherapy caused severe oral mucositis in 75% of patients in both arms. In patients receiving less toxic regimens, a decrease in WHO grade 1-4 oral mucositis was noted in the gum arm compared with the standard arm (49% vs. 72%, P=0.03). In the multivariate analysis, the risk of oral mucositis was related only to the type of chemotherapy regimen, suggesting that further strategies for preventing oral mucositis could be mainly based on these criteria. The efficacy of orally administered sucralfate suspension in preventing and treating chemotherapy-induced mucositis was evaluated in a double-blind trial. Forty-eight children and adolescents with newly diagnosed acute nonlymphocytic leukemia were randomized to receive suspensions of either sucralfate or placebo orally every 6 hours during the first 10 weeks of intensive remission-induction chemotherapy. Patients given sucralfate suspension were less likely than subjects receiving placebo to acquire colonization with potentially pathogenic microorganisms: 14 (58%) of 24 versus 22 (92%) of 24, respectively (p = 0.008). However, no effect on preexisting colonization was noted. Subjective reporting of discomfort, objective scoring of the severity of mucositis, and the maximal percent of body weight lost during therapy were similar; 58% of patients receiving sucralfate reported no oral pain compared with 25% receiving placebo (p = 0.06). Ten episodes of gastrointestinal bleeding, 25 documented infections, and 886 days with fever were also equally distributed between sucralfate and placebo groups. We conclude that sucralfate suspension is of limited, if any efficacy, in the prevention and treatment of chemotherapy-induced mucositis. Sucralfate administration can, however, reduce acquisition of alimentary colonization with potential pathogens, perhaps by interfering with adherence to mucosal membranes. From April 1993 to September 1993, 15 patients with lymphoid or solid neoplasms underwent 16 non-cryopreserved peripheral stem cell transplantation courses using the ICE (ifosfamide, carboplatin, etoposide) program. They were randomized in a double-blind clinical trial to received oral misoprostol or placebo for mucositis prophylaxis. The active drug or placebo administration began jointly with chemotherapy at day -4 and was continued until day 16. The mucositis incidence and severity was significantly higher in patients who received misoprostol. We found no differences regarding myelosuppression, infections or other chemotherapy complications. Our results do not support the use of oral misoprostol as administered in this study, for high-dose chemotherapy-induced mucositis prophylaxis. Mucositis, the inflammation and necrosis of mucosal membranes, is a serious and debilitating consequence of many cancer therapies. We were interested in the potential role of filgrastim (recombinant methionyl human granulocyte colony-stimulating factor, r-metHuG-CSF) in the reduction of mucositis. Patients with newly diagnosed small-cell lung cancer (SCLC) were treated with CAE chemotherapy (cyclophosphamide, doxorubicin, and etoposide) and placebo or filgrastim. If patients had an episode of febrile neutropenia, they received unblinded filgrastim in subsequent CAE cycles. Oral mucositis was considered to have occurred if a patient reported any clinical sign or symptom of oral mucositis with or without oral candidiasis. Oral mucositis was analyzed using the unadjusted chi-square test, and time to first episode of mucositis was analyzed using the stratified log-rank test as well as the Cox proportional hazards regression model. During cycle 1, placebo-treated patients had more episodes of mucositis (47%) compared with those patients randomized to filgrastim (28%). Across all cycles of treatment, 70% of placebo-treated patients experienced mucositis, compared with 53% of patients randomized to filgrastim. A significant reduction in the incidence of chemotherapy-related oral mucositis occurred across multiple cycles of treatment in patients treated with filgrastim. Stomatitis is a common consequence of chemotherapy and a condition for which there is little effective treatment. Although the management of patients with other chemotherapy-related toxicities has improved in recent years, the incidence of stomatitis is increasing because of more intensive treatment and is often a dose limiting factor in chemotherapy. The authors assessed the efficacy of a homeopathic remedy, TRAUMEEL S(R), in the management of chemotherapy-induced stomatitis in children undergoing bone marrow transplantation.
                A randomized, placebo-controlled, double-blind clinical trial was conducted in 32 patients ages 3-25 years who had undergone allogeneic (16 patients) or autologous (16 patients) stem cell transplantation. Of the 30 evaluable patients, 15 were assigned placebo, and 15 were assigned TRAUMEEL S both as a mouth rinse, administered five times daily from 2 days after transplantation for a minimum of 14 days, or until at least 2 days after all signs of stomatitis were absent. Stomatitis scores were evaluated according to the World Health Organization grading system for mucositis.
                A total of five patients (33%) in the TRAUMEEL S treatment group did not develop stomatitis compared with only one patient (7%) in the placebo group. Stomatitis worsened in only 7 patients (47%) in the TRAUMEEL S treatment group compared with 14 patients (93%) in the placebo group. The mean area under the curve stomatitis scores were 10.4 in the TRAUMEEL S treatment group and 24.3 in the placebo group. This difference was statistically significant (P < 0.01).
                This study indicates that TRAUMEEL S may reduce significantly the severity and duration of chemotherapy-induced stomatitis in children undergoing bone marrow transplantation.

                Forty patients with head and neck cancer were randomized to use either sucralfate mouth washing 1 g six times daily during irradiation (n = 20) or to placebo washing (n = 20). Mouth washing was started at the beginning of radiation therapy and continued to the end of the therapy (7-10 weeks). Assessment of the degree of radiation mucositis and collection of stimulated saliva samples were done weekly during the therapy. Salivary lactoferrin and albumin, suggested markers for the degree of mucositis, were analyzed from stimulated whole saliva samples.
                All patients developed radiation-induced mucositis of varying degree after irradiation of about 30 Gy. No difference in the visually assessed degree of mucositis or oral pain reported by the patients was found between the study and the control groups. However, the patients treated with sucralfate used less anesthetic mouth washing and their salivary lactoferrin and albumin levels were lower.
                Although the trial produced no direct clinical evidence indicating that sucralfate mouth rinses prevent radiation-induced mucositis, the decrease in the salivary lactoferrin and albumin levels suggests that sucralfate has a slight protective effect on the oral mucosa.
