The results of treatment of 686, previously untreated patients younger than 21 years with rhabdomyosarcoma or undifferentiated sarcoma, who were entered on Intergroup Rhabdomyosarcoma Study-I (IRS-I) were analyzed after a minimum potential follow-up time of 7 years. Patients in Clinical Group I (localized disease, completely resected) were randomized to receive either vincristine, dactinomycin, and cyclophosphamide (VAC) or VAC + radiation. At 5 years, approximately 80% of patients given either treatment were still disease-free and there was no significant difference between treatments in the overall percentages of patients surviving of 93% and 81%, respectively (P = 0.67). Patients in Clinical Group II (regional disease, grossly resected) were randomized to receive either vincristine and dactinomycin (VA) + radiation or VAC + radiation. At 5 years, 72% and 65% of the patients, respectively, were disease-free and there was no evidence of a difference between treatments (P = 0.46). The overall survival percentage at 5 years was approximately 72% for both treatments. Patients in Clinical Groups III (gross residual disease after surgery) and IV (metastatic disease) were randomized to receive either "pulse" VAC + radiation or "pulse" VAC + Adriamycin (doxorubicin) + radiation. The complete remission (CR) rate was 69% in Clinical Group III and 50% in IV, with no statistically significant difference in CR rates between treatments in either group. Those who achieved a CR had a nearly 60% chance of staying in remission for 5 years in Clinical Group III compared with approximately 30% in Clinical Group IV. The overall survival percentage at 5 years was 52% in Clinical Group III compared to 20% in Clinical Group IV (P less than 0.0001). The 5-year survival percentage for the entire cohort of 686 patients was 55%. Survival after relapse was poor, being 32% at 1 year and 17% at 2 years. The risk of distant metastasis was much greater than the risk of local recurrence within each clinical group, and there was no evidence of differing types of relapses between treatments. Primary tumors of the orbit and genitourinary tract carried the best prognosis, whereas tumors of the retroperitoneum had the worst prognosis. The authors conclude that for the therapeutic regimens evaluated there was no therapeutic advantage to including radiation in the treatment of Clinical Group I disease, or cyclophosphamide given as a daily low-dose oral regimen in the treatment of Clinical Group II disease or Adriamycin in the treatment of Clinical Groups III and IV diseases. The Dutch Childhood Leukemia Study Group (DCLSG) performed a phase III study-Study (ALL) V-to evaluate the effectiveness of rubidomycin in induction therapy with vincristine, prednisone, and L-asparaginase for children (0-15 years) with standard risk acute lymphoblastic leukemia (ALL) (white blood cell [WBC] counts less than 50.10(9)/L, absence of mediastinal mass, and/or cerebromeningeal leukemia). Furthermore, the influence of initial patient and disease characteristics on the outcome was analyzed. Between May 1979 and December 1982, 240 patients entered the study and were randomized into two groups: group A (n = 122) received induction treatment with vincristine (VCR), prednisone (Pred), and L-asparaginase (L-Asp); for group B (n = 118), induction therapy consisted of VCR, Pred, L-Asp, and rubidomycin (Rub). All patients subsequently underwent cranial irradiation (doses adjusted to age) in combination with intrathecal methotrexate; maintenance therapy of 6-mercaptopurine and methotrexate for 5 weeks followed by vincristine and prednisone for 2 weeks was given for 24 months. The complete remission (CR) rate was similar in both groups (94.5%). Event-free survival (EFS) 5 years after diagnosis was higher in group B (62.5 +/- 4.5%) than in group A (54.7 +/- 4.5%), although the difference is not significant (p = 0.20). A high initial WBC (greater than or equal to 10.10(9)/L), age (greater than or equal to 10 years), a low platelet count (less than 100.10(9)/L), and a positive acid phosphatase reaction of the leukemic cells were unfavorable prognostic factors (p less than 0.05). Sex, French-American-British (FAB) classification group, immunophenotype, and treatment in specialized centers did not have a significant impact on event-free survival. nan One-hundred-eighty-eight children up to 16 years of age were randomized in the second National Wilms' Tumor Study (NWTS) with tumors that were confined to the kidney and that had been totally excised (Group I). Most fared well whether treated for six or for 15 months with both actinomycin D (AMD) and vincristine (VCR). No postoperative radiation therapy (RT) was given. The two-year relapse-free survival (RFS) and two-year survival rates were 88 and 95%, respectively. Two-hundred-sixty-eight randomized patients with more advanced local lesions (Groups II and III) and 57 with distant metastases (Group IV) had postoperative RT and were scheduled for 15 months treatment with either AMD and VCR (Reg. C) or AMD plus VCR plus Adriamycin (Reg. D). The 77% two-year RFS rate for Reg. D was significantly different from the 63% with Reg. C. As in the first NWTS, patients with tumors of unfavorable histology (UH) had a significantly worse prognosis than those with favorable histology (FH), as did those with positive nodes. Survival rates at two years were 54% for UH vs. 90% for FH, and 54% vs. 82% for those with and without lymph node involvement. During the 1970s, despite apparently similar treatment, the prognosis for children with lymphoblastic leukaemia (ALL) improved more in some countries, notably the United States and West Germany, than in others. To find out why, the first phase of the United Kingdom (UK) Medical Research Council (MRC) childhood ALL trial, UKALL VIII, was designed to see whether similar results to the United States Children's Cancer Study Group (CCSG) could be obtained in the U.K. using an identical protocol (CCG 162). Protocol 162 was one of a series of regimens devised by the American Children's Cancer Study Group in the 1970s and was used specifically for their average risk patients (all children with ALL with an initial white cell count up to 50 x 10(9)/l except those aged 3-6 years with white cell counts under 10 x 10(9)/l). One arm (1A) of their study was adopted by the MRC for all children in the U.K. aged 0-14 years with confirmed ALL. Eight hundred and twenty-nine consecutive patients were entered between 1980 and 1984. The first 199 patients formed a single arm study as per the original protocol 162 (arm 1A), but the subsequent 630 children were randomized to receive or not two doses of daunorubicin on the first 2 d of induction. This randomization was an attempt to answer the important question as to whether event-free survival was influenced by the use of four rather than three induction agents. A second randomization between 2 and 3 years continuing therapy was also introduced at this stage as it had been by the CCSG in their protocol. With a minimum follow up period of more than 5 years, disease-free survival for the whole group is 55%, a considerable improvement on all previous UKALL trials. Results for patients directly comparable with those in CCSG 162 ('average risk' patients) and their American counterparts were similar. Daunorubicin was associated with more early deaths but improved disease-free survival for those achieving remission. More children relapsed who stopped treatment after 2 years than those who continued for 3, but this was balanced by increased treatment mortality in the third year. The fact that for UKALL VIII the results were similar to those of the CCSG suggests that previous MRC protocols were not sufficiently sustained and intensive, particularly during the maintenance phase of treatment.(ABSTRACT TRUNCATED AT 400 WORDS) A total of 342 previously untreated eligible children were entered into the first Intergroup Ewing's Sarcoma Study (IESS) between May 1973 and November 1978. In group I institutions, patients were randomized between treatment 1 (radiotherapy to primary lesion plus cyclophosphamide, vincristine, dactinomycin, and Adriamycin [doxorubicin; Adria Laboratories, Columbus, OH] [VAC plus ADR]) or treatment 2 (same as treatment 1 without ADR), and group II institutions randomized patients between treatment 2 or treatment 3 (same as treatment 2 plus bilateral pulmonary radiotherapy [VAC plus BPR]). The percentages of patients relapse-free and surviving (RFS) at 5 years for treatments 1, 2, and 3 were 60%, 24%, and 44%, respectively. There was strong statistical evidence of a significant advantage in RFS for treatment 1 (VAC plus ADR) versus 2 (VAC alone) (P less than .001) and 3 (P less than .05) and also of treatment 3 versus 2 (P less than .001). Similar significant results were observed with respect to overall survival. Patients with disease at pelvic sites have significantly poorer survival at 5 years than those with disease at nonpelvic sites (34% v 57%; P less than .001). Among pelvic cases, there was no evidence of differing survival by treatment (P = .81), but among nonpelvic cases, there was strong evidence of differing survival by treatment (P less than .001). The overall percentage of patients developing metastatic disease was 44%; the percentages by treatments 1, 2, and 3 were 30%, 72%, and 42%, respectively. The overall incidence of local recurrence was 15%, and there was no evidence that local recurrence rate differed by treatment. Patient characteristics related to prognosis, both with respect to RFS and overall survival experience, were primary site (nonpelvic patients were most favorable) and patient age (younger patients were more favorable). Early Children's Cancer Group (CCG) trials indicated that the cyclophosphamide, vincristine, methotrexate, and prednisone (COMP) regimen was superior to the LSA2L2 regimen for non-lymphoblastic (NLB) non-Hodgkin lymphoma (NHL). Studies by other groups suggested that addition of anthracyclines to standard therapies could improve outcome. Therefore, in 1983 CCG initiated study CCG-503, a randomized trial of COMP vs. daunomycin-COMP (D-COMP) in children and adolescents with disseminated NLB NHL.
                Between December 1983 and April 1990, 404 eligible patients were entered. Patients without central nervous system (CNS) or marrow involvement were randomized to receive COMP (N = 139) or D-COMP (N = 145). Randomization was stratified by histology and site of disease. Patients with CNS or marrow involvement (stage IV) were non-randomly treated with D-COMP (N = 120).
                Ten-year event-free survival in COMP and D-COMP patients was similar: 55 +/- 4.3% (Estimate +/- SE) vs. 57 +/- 4.2% (not significant). Stage I-III patients with large-cell (LC) NHL had worse 10-year event-free survival (EFS) (48 +/- 4.9%) than those with small non-cleaved cell (SNCC) NHL disease (61 +/- 3.5%, P < 0.05 in multivariate analysis), but equivalent survival (65 +/- 4.7% vs. 63 +/- 3.5%) due to significantly higher salvage rates in LC patients, especially those failing more than 12 months from diagnosis. Ten-year EFS in stage IV patients was 39 +/- 5.2%. Addition of daunomycin resulted in higher rates of grade 3/4 hematologic toxicity and stomatitis, as well as late cardiac-related deaths. The incidence of second malignant neoplasms was 1.0% at 10 years.
                Addition of daunomycin to standard COMP therapy did not improve outcome in pediatric disseminated NLB NHL. Patients with LC disease had a significantly reduced long-term EFS, but were retrieved at a higher rate than patients with SNCC disease, resulting in equivalent long-term survival.
                Copyright 2001 Wiley-Liss, Inc. Preoperative cisplatin alone may be as effective as cisplatin plus doxorubicin in standard-risk hepatoblastoma (a tumor involving three or fewer sectors of the liver that is associated with an alpha-fetoprotein level of >100 ng per milliliter).
                Children with standard-risk hepatoblastoma who were younger than 16 years of age were eligible for inclusion in the study. After they received one cycle of cisplatin (80 mg per square meter of body-surface area per 24 hours), we randomly assigned patients to receive cisplatin (every 14 days) or cisplatin plus doxorubicin administered in three preoperative cycles and two postoperative cycles. The primary outcome was the rate of complete resection, and the trial was powered to test the noninferiority of cisplatin alone (<10% difference in the rate of complete resection).
                Between June 1998 and December 2006, 126 patients were randomly assigned to receive cisplatin and 129 were randomly assigned to receive cisplatin plus doxorubicin. The rate of complete resection was 95% in the cisplatin-alone group and 93% in the cisplatin-doxorubicin group in the intention-to-treat analysis (difference, 1.4%; 95% confidence interval [CI], -4.1 to 7.0); these rates were 99% and 95%, respectively, in the per-protocol analysis. Three-year event-free survival and overall survival were, respectively, 83% (95% CI, 77 to 90) and 95% (95% CI, 91 to 99) in the cisplatin group, and 85% (95% CI, 79 to 92) and 93% (95% CI, 88 to 98) in the cisplatin-doxorubicin group (median follow-up, 46 months). Acute grade 3 or 4 adverse events were more frequent with combination therapy (74.4% vs. 20.6%).
                As compared with cisplatin plus doxorubicin, cisplatin monotherapy achieved similar rates of complete resection and survival among children with standard-risk hepatoblastoma. Doxorubicin can be safely omitted from the treatment of standard-risk hepatoblastoma. (ClinicalTrials.gov number, NCT00003912.)

At the moment no evidence from RCTs is available which underscores the use of anthracyclines in ALL. However, "no evidence of effect", as identified in this review, is not the same as "evidence of no effect". For Wilms' tumour, rhabdomyosarcoma/undifferentiated sarcoma, Ewing's sarcoma, non-Hodgkin lymphoma and hepatoblastoma only one RCT was available and, therefore, no definitive conclusions can be made about the antitumour efficacy of treatment with or without anthracyclines in these tumours. For other childhood cancers no RCTs were identified and therefore, no conclusions can be made about the antitumour efficacy of treatment with or without anthracyclines in these tumours.
