PURPOSE The aims of this pilot study were the following : 1 ) to examine patterns of adherence to a brisk walking program in women receiving adjuvant chemotherapy or radiation therapy for newly diagnosed breast cancer using a prospect i ve , r and omized , controlled experimental design ; 2 ) to examine the influence of disease symptoms and treatment side effects on exercise levels ; and 3 ) to suggest methods that may improve future clinical trials of moderate-intensity exercise in similar population s. DESCRIPTION OF STUDY Fifty-two patients with newly diagnosed breast cancer were r and omly assigned to one of two treatment arms : usual care or usual care plus exercise . Those assigned to the exercise group received a st and ardized , self-administered , home-based brisk walking intervention in addition to usual care . Each day subjects completed self-report diary forms that elicited information about activity levels , and the occurrence of symptoms and side effects during cancer treatment . RESULTS Analyses of self-reported daily activity levels revealed a diffusion of treatment effect . Fifty percent of the usual-care group reported maintaining or increasing their physical activity to a moderate-intensity level , while 33 % of the exercise group did not exercise at the prescribed levels . Analyses of self-reported disease symptoms and treatment side effects did not reveal clinical ly meaningful differences between the two groups . CLINICAL IMPLICATION S The results of this study suggest that women who exercised regularly before receiving a breast cancer diagnosis attempted to maintain their exercise programs . Women who lead sedentary lifestyles may benefit from a structured exercise program that includes information and support related to exercise adherence strategies Research suggests that stress‐reduction programs tailored to the cancer setting help patients cope with the effects of treatment and improve their quality of life .  Yoga , an ancient Eastern science , incorporates stress‐reduction techniques that include regulated breathing , visual imagery , and meditation as well as various postures . The authors examined the effects of the  Tibetan yoga ( TY ) practice s of Tsa lung and Trul khor , which incorporate  controlled breathing and visualization , mindfulness techniques  , and low‐impact postures  in patients with lymphoma BACKGROUND AND OBJECTIVES This pilot project assessed the acceptability of a mixed-type , moderate-intensity exercise programme  following breast cancer treatment , and the impact on presence of lymphoedema , fitness , body composition , fatigue , mood and quality of life . METHODS Ten women completed the programme and measures of fitness ( sub-maximal ergometer test ) , body composition ( bio-electrical impedance ) , lympoedema ( bio-electrical impedance and arm circumferences ) , fatigue ( revised Piper Fatigue Scale ) , mood ( Hospital Anxiety and Depression Scale ) , quality of life ( FACT-B ) and general well-being , at baseline , completion of the programme , and 6-week and 3-month follow-up . RESULTS Participation in the programme caused no adverse effect on the presence of lymphoedema . There was a trend towards reduction in fatigue and improved quality of life across the testing phases . Women rated the programme extremely favourably , citing benefits of the support of other women , trained guidance , and the opportunity to experience different types of exercise . CONCLUSIONS A mixed-type , moderate-intensity exercise program in a group format is acceptable to women following breast cancer treatment , with the potential to reduce fatigue and improve quality of life , without exacerbating or precipitating lymphoedema . This pilot work needs to be confirmed in larger r and omised studies PURPOSE The primary purpose of this study was to examine the effect of aerobic exercise on physiological and psychological function in patients rehabilitating from cancer treatment . A second purpose was to evaluate the differential effects of low- and moderate-intensity exercise on these variables . METHODS Eighteen survivors of breast or colon cancer ( 15 female and 3 male , 40 - 65 yr of age ) served as subjects . The subjects were matched by aerobic capacity and scores on a Quality of Life question naire , and then r and omly assigned to a control , low- ( 25 - 35 % heart rate reserve ( HRR ) ) , or a moderate- ( 40 - 50 % HRR ) intensity exercise group . The exercise groups performed lower-body aerobic exercise three times a week for 10 wk . After the exercise training , there were no statistically significant differences between the two exercise groups on any of the physiological variables . Therefore , the exercise groups were combined into one group for the final analysis . RESULTS The results revealed statistically significant increases in aerobic capacity ( P < 0.001 ) and lower-body flexibility ( P = 0.027 ) , a significant decrease in body fat ( P < 0.001 ) , and a significant increase in quality of life ( P < 0.001 ) and a measure of energy ( P = 0.038 ) in the exercise group when compared with the control group . CONCLUSION Low- and moderate-intensity aerobic-exercise programs were equally effective in improving physiological and psychological function in this population of cancer survivors .  Aerobic exercise appears to be a valuable and well-tolerated component of the cancer-rehabilitation process The efficacy of energy conservation and activity management ( ECAM ) for fatigue reduction and maintenance of functional performance has never been evaluated in adults with cancer who are undergoing treatment PURPOSE Self-directed and supervised exercise were compared with usual care in a clinical trial design ed to evaluate the effect of structured exercise on physical functioning and other dimensions of health-related quality of life in women with stages I and II breast cancer . PATIENTS AND METHODS One hundred twenty-three women with stages I and II breast cancer completed baseline evaluations of generic and disease- and site-specific health-related quality of life , aerobic capacity , and body weight . Participants were r and omly allocated to one of three intervention groups : usual care ( control group ) , self-directed exercise , or supervised exercise .  Quality of life , aerobic capacity , and body weight measures were repeated at 26 weeks . The primary outcome was the change in the Short Form-36 physical functioning scale between baseline and 26 weeks . RESULTS Physical functioning in the control group decreased by 4.1 points , whereas it increased by 5.7 points and 2.2 points in the self-directed and supervised exercise groups , respectively ( P = .04 ) . Post hoc analysis showed a moderately large ( and clinical ly important ) difference between the self-directed and control groups ( 9.8 points ; P = .01 ) and a more modest difference between the supervised and control groups ( 6.3 points ; P = .09 ) . No significant differences between groups were observed for changes in quality of life scores . In a secondary analysis of participants stratified by type of adjuvant therapy , supervised exercise improved aerobic capacity ( + 3.5 mL/kg/min ; P = .01 ) and reduced body weight ( -4.8 kg ; P < .05 ) compared with usual care only in participants not receiving chemotherapy . CONCLUSION Physical exercise can blunt some of the negative side effects of breast cancer treatment , including reduced physical functioning .  Self-directed exercise is an effective way to improve physical functioning compared with usual care . In participants not receiving chemotherapy  , supervised exercise may increase aerobic capacity and reduce body weight compared with usual care PURPOSE To determine the effects of breast cancer-specific print material s and step pedometers on  physical activity ( PA ) and quality of life ( QoL ) in breast cancer survivors . PATIENTS AND METHODS Breast cancer survivors ( N = 377 ) were r and omly assigned to receive one of the following : a st and ard public health recommendation for PA , previously developed breast cancer-specific PA print material s , a step pedometer , or a combination of breast cancer-specific print material s and step pedometers . The primary outcome was self-reported moderate/vigorous PA minutes per week . Secondary outcomes were QoL ( Functional Assessment of Cancer Therapy-Breast ) , fatigue , self-reported brisk walking , and objective step counts . Assessment s were conducted at baseline and postintervention ( 12 weeks ) . RESULTS Attrition was 10.3 % ( 39 of 377 ) . On the basis of linear mixed-model analyses , PA increased by 30 minutes/week in the st and ard recommendation group compared with 70 minutes/week in the print material group ( mean difference , 39 minutes/week ; 95 % CI = -10 to 89 ; d = 0.25 ; P = .117 ) , 89 minutes/week in the pedometer group ( mean difference , 59 minutes/week ; 95 % CI , 11 to 108 ; d = 0.38 ; P = .017 ) , and 87 minutes/week in the combined group ( mean difference , 57 minutes/week ; 95 % CI , 8 to 106 ; d = 0.37 ; P = .022 ) . For brisk walking minutes/week , all three intervention groups reported significantly greater increases than the st and ard recommendation group . The combined group also reported significantly improved QoL ( mean difference , 5.8 ; 95 % CI , 2.0 to 9.6 ; d = 0.33 ; P = .003 ) and reduced fatigue ( mean difference , 2.3 ; 95 % CI , 0.0 to 4.7 ; d = 0.25 ; P = .052 ) compared with the st and ard recommendation group . CONCLUSION Breast cancer-specific PA print material s and pedometers may be effective strategies for increasing PA and QoL in breast cancer survivors . A combined approach appears to be optimal . CLINICAL TRIAL REGISTRATION Clinical Trials.gov Identifier PURPOSE Cancer treatment-related fatigue is the most prevalent and distressing symptom of cancer therapy . Interventions to minimize fatigue are needed . The purpose of this study was to examine the relationship between exercise and fatigue over the first three cycles of chemotherapy in women receiving either cyclophosphamide , methotrexate , and fluorouracil ( CMF ) or doxorubicin and cyclophosphamide ( AC ) for breast cancer . METHODS Seventy-two newly diagnosed women with breast cancer were instructed in a home-based moderate-intensity exercise intervention . Measures of functional ability , energy expenditure , and fatigue were obtained at baseline and posttest . Subjects maintained daily records of four types of fatigue , and exercise duration , intensity , and type . RESULTS Exercise significantly reduced all four levels of fatigue ( P < 0.01 ) . As the duration of exercise increased , the intensity of fatigue declined ( P < 0.01 ) . There was a significant carry-over effect of exercise on fatigue , but the effect lasted only 1 d. The level of fatigue at study entry was not associated with number of days of exercise or amount of exercise a woman engaged in . CONCLUSIONS The impact of exercise on fatigue was significant and suggests the effectiveness of a low- to moderate-intensity regular exercise program in maintaining functional ability and reducing fatigue in women with breast cancer receiving chemotherapy BACKGROUND Physical activity provides a number of physical and psychological benefits to cancer survivors , including lessening the impact of detrimental cancer-related symptoms and treatment side-effects ( e.g. fatigue , nausea ) , and improving overall well-being and quality of life . The purpose of the present pilot study was to examine the physical and psychological benefits afforded by a 7-week yoga program for cancer survivors . METHOD Eligible participants ( per-screened with PAR-Q/PAR-MED-X ) were r and omly assigned to either the  intervention ( n=20 ) or control group ( n=18 ) . All participants completed pre- and post-testing assessment s immediately before and after the yoga program , respectively . RESULTS The yoga program participants ( M age=51.18 ( 10.33 ) ; 92 % female ) included primarily breast cancer survivors , on average 55.95 ( 54.39 ) months post-diagnosis . Significant differences between the intervention and the control group at post-intervention were seen only in psychosocial ( i.e. global quality of life , emotional function , and diarrhea ) variables ( all p 's < 0.05 ) . There were also trends for group differences , in the hypothesized directions , for the psychosocial variables of emotional irritability , gastrointestinal symptoms , cognitive disorganization , mood disturbance , tension , depression , and confusion ( all p 's < 0.10 ) . Finally , there were also significant improvements in both the program participants and the controls from pre- to post-intervention on a number of physical fitness variables . CONCLUSIONS These initial findings suggest that yoga has significant potential and should be further explored as a beneficial physical activity option for cancer survivors . Future research might attempt to include a broader range of participants ( e.g. other types of cancer diagnoses , male subjects ) , a larger sample size , and a longer program duration in an RCT AIM Our purpose was to investigate the effect of a relaxation breathing exercise on fatigue in allogenic haemopoietic stem cell transplantation patients . BACKGROUND Exercise is a promising approach in ameliorating the fatigue associated with cancer and its treatment . DESIGN A r and omized design with control , experimental groups being assessed pre- and postintervention . METHODS Thirty-five patients were r and omly selected , with 18 assigned to an exercise group and 17 to a control group .  The exercise intervention lasted for 30 minutes every day for six weeks . It consisted of physical exercise combined with relaxation breathing exercise .  Fatigue was measured by the revised version of the Piper Fatigue Scale . RESULTS The exercise group had a greater decrease in fatigue than the control group . CONCLUSION These findings indicate that a relaxation breathing exercise would improve fatigue in allogenic haemopoietic stem cell transplantation patients . RELEVANCE TO CLINICAL PRACTICE A relaxation breathing exercise by a nurse can improve fatigue in allogenic haemopoietic stem cell transplantation patients Advice to rest and take things easy if patients become fatigued during radiotherapy may be detrimental . Aerobic walking improves physical functioning and has been an intervention for chemotherapy‐related fatigue . A prospect i ve , r and omized , controlled trial was performed to determine whether aerobic exercise would reduce the incidence of fatigue and prevent deterioration in physical functioning during radiotherapy for localized prostate carcinoma Fatigue is a frequent problem after surgical treatment of solid tumours . Aerobic exercise and psychosocial interventions have been shown to reduce the severity of this symptom in cancer patients . Therefore , we compared the effect of the two therapies on fatigue in a r and omised controlled study . Seventy-two patients who underwent surgery for lung ( n=27 ) or gastrointestinal tumours ( n=42 ) were assigned to an aerobic exercise group ( stationary biking 30 min five times weekly ) or a progressive relaxation training group ( 45 min three times per week ) . Both interventions were carried out for 3 weeks . At the beginning and the end of the study , we evaluated physical , cognitive and emotional status and somatic complaints with the European Organization for Research and Treatment of Cancer Quality of Life Question naire Core Module ( EORTC-QLQ-30 ) question naire , and maximal physical performance with an ergometric stress test . Physical performance of the training group improved significantly during the programme ( 9.4±20 watts , p=0.01 ) but remained unchanged in the relaxation group ( 1.5±14.8 watts , p=0.37 ) . Fatigue and global health scores improved in both groups during the intervention ( fatigue : training group 21 % , relaxation group 19 % ; global health of both groups 19 % , p for all ≤0.01 ) ; however , there was no significant difference between changes in the scores of both groups ( p=0.67 ) . We conclude that a structured aerobic training programme improves the physical performance of patients recovering from surgery for solid tumours . However , exercise is not better than progressive relaxation training for the treatment of fatigue in this setting Loss of physical performance is a universal problem of cancer patients undergoing chemotherapy .  We postulated that this impairment can be partially prevented by aerobic exercise . In a r and omized study , 33 cancer patients receiving high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation ( training group , T ) performed an exercise program consisting of biking on an ergometer in the supine position after an interval-training pattern for 30 minutes daily during hospitalization . Patients in the  control group ( C , n = 37 )  did not train . Maximal physical performance was assessed with a treadmill test by admission and discharge . Physical performance of the two groups was not different on admission . The decrement in performance during hospitalization was 27 % greater in the control group than in the training group ( P = .05 ) ; this result ed in a significantly higher maximal physical performance at discharge in the trained patients ( P = .04 ) . Duration of neutropenia ( P = .01 ) and thrombopenia ( P = .06 ) , severity of diarrhea ( P = .04 ) , severity of pain ( P = .01 ) , and duration of hospitalization ( P = . 03 ) were reduced in the training group . We conclude that aerobic exercise can be safely carried out immediately after high-dose chemotherapy and can partially prevent loss of physical performance . Based on the potential significance of the observed outcomes , further studies are warranted to confirm our results Objectives To determine functional and psychological benefits of a 12 week supervised group exercise programme during treatment for early stage breast cancer , with six month follow-up . Design Pragmatic r and omised controlled prospect i ve open trial . Setting Three National Health Service oncology clinics in Scotl and and community exercise facilities . Participants 203 women entered the study ; 177 completed the six month follow-up . Interventions Supervised 12 week group exercise programme in addition to usual care , compared with usual care . Main outcome measures Functional assessment of cancer therapy ( FACT ) question naire , Beck depression inventory , positive and negative affect scale , body mass index , seven day recall of physical activity , 12 minute walk test , and assessment of shoulder mobility . Results Mixed effects models with adjustment for baseline values , study site , treatment at baseline , and age gave intervention effect estimates ( intervention minus control ) at 12 weeks of 129 ( 95 % confidence interval 83 to 176 ) for metres walked in 12 minutes , 182 ( 75 to 289 ) for minutes of moderate intensity activity reported in a week , 2.6 ( 1.6 to 3.7 ) for shoulder mobility , 2.5 ( 1.0 to 3.9 ) for breast cancer specific subscale of quality of life , and 4.0 ( 1.8 to 6.3 ) for positive mood . No significant effect was seen for general quality of life ( FACT-G ) , which was the primary outcome . At the six month follow-up , most of these effects were maintained and an intervention effect for breast cancer specific quality of life emerged . No adverse effects were noted . Conclusion Supervised group exercise provided functional and psychological benefit after a 12 week intervention and six months later . Clinicians should encourage activity for their patients . Policy makers should consider the inclusion of exercise opportunities in cancer rehabilitation services . Trial registration Current controlled trials IS RCT N12587864 PURPOSE To examine the effects of aerobic exercise therapy on quality of life ( QoL ) and associated outcomes in women treated for breast cancer . Evidence suggests that exercise may be beneficial , but no trial has included an exercise-placebo and a usual-care group to control for the attention effects that might be associated with aerobic exercise interventions in cancer patients . PATIENTS AND METHODS A total of 108 women who had been treated for breast cancer 12 to 36 months previously were r and omly assigned to supervised aerobic exercise therapy ( n = 34 ) , exercise-placebo ( body conditioning ; n = 36 ) , or usual care ( n = 38 ) . Exercise therapy and exercise-placebo sessions took place three times per week for 8 weeks . Outcomes included QoL , depression , exercise behavior , aerobic fitness ; outcomes were assessed at baseline and at the 8- and 24-week follow-up . RESULTS Analyses of covariance revealed a significant mean difference of 9.8 units in Functional Assessment of Cancer Therapy-General ( primary outcome ) favoring aerobic exercise therapy at 8 weeks , relative to usual care . Significant differences that favored aerobic exercise therapy relative to usual care were recorded for Functional Assessment of Cancer Therapy-Breast , social/family well-being , functional well-being , and breast cancer subscale scores at 8-week follow-up . Psychological health outcomes improved modestly for both intervention groups ; these improvements were sustained for several end points . CONCLUSION Exercise therapy had large , clinical ly meaningful , short-term beneficial effects on QoL in women treated for breast cancer ; this finding can not be attributable to attention , given that the exercise-placebo group did not report similar effects relative to usual care PURPOSE To determine the effects of exercise training on cardiopulmonary function and quality of life ( QOL ) in postmenopausal breast cancer survivors who had completed surgery , radiotherapy , and /or chemotherapy with or without current hormone therapy use . METHODS Fifty-three postmenopausal breast cancer survivors were r and omly assigned to an exercise ( n = 25 ) or control ( n = 28 ) group . The exercise group trained on cycle ergometers three times per week for 15 weeks at a power output that elicited the ventilatory equivalent for carbon dioxide . The control group did not train . The primary outcomes were changes in peak oxygen consumption and overall QOL from baseline to postintervention . Peak oxygen consumption was assessed by a grade d exercise test using gas exchange analysis . Overall QOL was assessed by the Functional Assessment of Cancer Therapy-Breast scale . RESULTS Fifty-two participants completed the trial . The exercise group completed 98.4 % of the exercise sessions . Baseline values for peak oxygen consumption ( P = .254 ) and overall QOL ( P = .286 ) did not differ between groups . Peak oxygen consumption increased by 0.24 L/min in the exercise group , whereas it decreased by 0.05 L/min in the control group ( mean difference , 0.29 L/min ; 95 % confidence interval [ CI ] , 0.18 to 0.40 ; P < .001 ) . Overall QOL increased by 9.1 points in the exercise group compared with 0.3 points in the control group ( mean difference , 8.8 points ; 95 % CI , 3.6 to 14.0 ; P = .001 ) . Pearson correlations indicated that change in peak oxygen consumption correlated with change in overall QOL ( r = 0.45 ; P < .01 ) . CONCLUSION Exercise training had beneficial effects on cardiopulmonary function and QOL in postmenopausal breast cancer survivors PURPOSE Breast cancer chemotherapy  may cause unfavorable changes in physical functioning , body composition , psychosocial functioning , and quality of life ( QOL ) . We evaluated the relative merits of aerobic and resistance exercise in blunting these effects . PATIENTS AND METHODS We conducted a multicenter r and omized controlled trial in Canada between 2003 and 2005 that r and omly assigned 242 breast cancer patients initiating adjuvant chemotherapy to usual care ( n = 82 ) , supervised resistance exercise  ( n = 82 ) , or supervised aerobic exercise  ( n = 78 ) for the duration of their chemotherapy ( median , 17 weeks ; 95 % CI , 9 to 24 weeks ) . Our primary end point was cancer-specific QOL assessed by the Functional Assessment of Cancer Therapy-Anemia scale . Secondary end points were fatigue , psychosocial functioning , physical fitness , body composition , chemotherapy completion rate , and lymphedema . RESULTS The follow-up assessment rate for our primary end point was 92.1 % , and adherence to the supervised exercise was 70.2 % . Unadjusted and adjusted mixed-model analyses indicated that aerobic exercise was superior to usual care for improving self-esteem ( P = .015 ) , aerobic fitness ( P = .006 ) , and percent body fat ( adjusted P = .076 ) . Resistance exercise was superior to usual care for improving self-esteem ( P = .018 ) , muscular strength ( P < .001 ) , lean body mass ( P = .015 ) , and chemotherapy completion rate ( P = .033 ) . Changes in cancer-specific QOL , fatigue , depression , and anxiety favored the exercise groups but did not reach statistical significance . Exercise did not cause lymphedema or adverse events . CONCLUSION Neither aerobic nor resistance exercise significantly improved cancer-specific QOL  in breast cancer patients receiving chemotherapy , but they did improve self-esteem , physical fitness , body composition , and chemotherapy completion rate without causing lymphedema or significant adverse events PURPOSE Despite the recognition of fatigue as a common and distressing symptom during cancer treatment , there are few evidence -based interventions available to manage such fatigue . The purpose of this multi-institutional pilot study was to explore the effects of a home-based moderate walking exercise intervention on fatigue , physical functioning , emotional distress , and quality of life ( QOL ) during breast cancer treatment . DESCRIPTION OF STUDY Fifty-two women were recruited from five university hospital outpatient departments for this pilot study with an experimental design . Subjects were r and omly assigned to the walking program or to usual care during adjuvant chemotherapy or radiation therapy for breast cancer . Symptoms , physical functioning , and QOL were measured at baseline , midtreatment , and at the end of treatment . RESULTS Women who exercised at least 90 minutes per week on 3 or more days reported significantly less fatigue and emotional distress as well as higher functional ability and QOL than women who were less active during treatment . CLINICAL IMPLICATION S A home-based walking exercise program is a potentially effective , low-cost , and safe intervention to manage fatigue and to improve QOL during adjuvant chemotherapy or radiation therapy for breast cancer . This health-promoting self-care activity needs further testing in large r and omized clinical trials BACKGROUND Anemia is common in cancer and has been associated with fatigue and reduced health-related quality of life ( HRQOL ) . We report the association between hemoglobin and fatigue and the impact of reducing fatigue on several domains of HRQOL . PATIENTS AND METHODS These analyses were based on five r and omized trials . Patients completed the Functional Assessment of Cancer Therapy ( FACT ) Anemia scales and numeric rating scales of Energy , Activity and Overall Health  at baseline and after the 12-week treatment period . t-tests and linear regression models were used to evaluate associations . Analyses were stratified into three groups : solid tumor chemotherapy patients , lymphoproliferative malignancy chemotherapy patients and non-chemotherapy patients . RESULTS Adjusted mean differences ( 95 % CI ) in FACT Fatigue change scores between hemoglobin responders ( > or = 2 g/dl increase ) and non-responders were 3.0 ( 1.2 , 4.7 ) , 2.8 ( 0.6 , 5.0 ) and 5.8 ( 2.2 , 9.5 ) among the solid tumor , lymphoproliferative malignancy and non-chemotherapy groups , respectively . Significantly greater improvements ( P < 0.01 ) were observed in the FACT well-being scales for patients with meaningful improvement in fatigue ( FACT Fatigue change score > or =3 points ) . After controlling for other factors , patients whose fatigue improved reported substantially greater improvements in energy , ability to perform usual activities and overall health ( P < 0.0001 ) . CONCLUSIONS Across five trials of cancer patients on and off chemotherapy , hemoglobin response was associated with meaningful improvements in fatigue , which , in turn , was associated with improved physical , functional , emotional and overall well-being PURPOSE To examine the effect of a progressive upper-body exercise program on  lymphedema secondary to breast cancer treatment . METHODS Fourteen breast cancer survivors with unilateral upper extremity lymphedema were r and omly assigned to an exercise ( n = 7 ) or control group ( n = 7 ) . The exercise group followed a progressive , 8-week upper-body exercise program consisting of resistance training plus aerobic exercise using a Monark Rehab Trainer arm ergometer . Lymphedema was assessed by arm circumference and measurement of arm volume by water displacement . Patients were evaluated on five occasions over the experimental period . The Medical Outcomes Trust Short-Form 36 Survey was used to measure quality of life before and after the intervention . Significance was set at alpha < or = 0.01 . RESULTS No changes were found in arm circumference or arm volume as a result of the exercise program . Three of the quality -of-life domains showed trends toward increases in the exercise group : physical functioning ( P = .050 ) , general health ( P = .048 ) , and vitality ( P = .023 ) . Mental health increased , although not significantly , for all subjects ( P = .019 ) . Arm volume measured by water displacement was correlated with calculated arm volume ( r = .973 , P < .001 ) , although the exercise and control group means were significantly different ( P < .001 ) . CONCLUSIONS Participation in an upper-body exercise program caused no changes in arm circumference or arm volume in women with lymphedema after breast cancer , and they may have experienced an increase in quality of life . Additional studies should be done in this area to determine the optimum training program Fatigue is one of the most frequent side effects of cancer treatments . According to a number of studies , the incidence of fatigue as a side effect of radiation therapy ( RT ) ranges from 65 % to 100 % depending on which instruments were used ( Greenberg et al. , 1992 ; Jacobsen-Thors , 2003 ) . For many cancer patients , cancer-related fatigue is severe and imposes limitations on normal daily activities ( JereczekFossa et al. , 2002 ) . Patients often report that cancerrelated fatigue differs from fatigue experienced before initiation of cancer . They describe it as severe , chronic and frustrating , effects that fail to be relieved by rest . In many studies in the past , patients have felt that fatigue has adversely affected their quality of life more than pain and sexual dysfunction or other treatment-related side effects ( Stone et al. , 1998 ) . Fatigue has negative impact on various aspects of quality of life , so it is imperative to find non-invasive and nonpharmacological solutions for managing it . There is little however known as to which techniques can help alleviate fatigue .  Physical exercise has been shown to be effective , convenient and a low-cost self-care method for reducing anxiety and sleep difficulties , and increasing adaptation during radiotherapy . Aerobic exercises ( e.g. walking ) have been suggested for the rehabilitation of cancer patients affected by energy loss but this is not a fully accepted approach as yet . Nevertheless , exercise has been shown Purpose : Fatigue is a common side effect of cancer treatment that impacts quality of life .  Exercise is one approach suggested to improve fatigue . The purpose of this study was to explore the relationship of exercise to fatigue and quality of life . Methods : Thirty-one subjects with breast cancer were enrolled prior to beginning chemotherapy and 27 completed the study . All baseline measures were obtained before the first chemotherapy treatment . Subjects were instructed on a home-based , 8-week exercise program . Results : Women who adopted the exercise program ( 60 % ) showed significant increases in functional ability and less weight gain . Exploratory , stepwise multiple regression analyses suggested that the maximum effect of exercise on quality of life outcomes may be mediated by fatigue . Conclusions : The low-to-moderate intensity , home-based exercise program was feasible for some women with breast cancer receiving chemotherapy .  The results suggest that exercise may affect quality of life and that this effect may be mediated by the effects of exercise on fatigue . Better retention of functional ability and better weight control are additional possible benefits of exposing breast cancer patients to increased exercise . A r and omized , controlled clinical trial is needed to establish confidence in these observed relationships This pilot study examined whether exercise as an adjunctive rehabilitation therapy could benefit women who have early stage breast cancer and are currently receiving chemotherapy/radiotherapy . The study was design ed as a r and omised controlled trial ( RCT ) . Physical functioning , fatigue and Quality of Life ( QoL ) outcomes were evaluated pre and post a 12-week intervention . The results showed that after 12 weeks the women who participated in the exercise programme ( n = 12 ) displayed significantly higher levels of physical functioning and reported higher QoL scores than the controls ( n = 10 ) . Changes in fatigue and satisfaction with life favoured the intervention group but did not reach significance . These results are encouraging and suggest that a structured group exercise programme during adjuvant treatment is a safe , well tolerated and effective way of providing physical and psychological health benefits to women during treatment for early stage breast cancer . Since this was a pilot study the numbers did not allow appropriately powered analyses of some variables of interest and favoured relatively young and socio-economically advantaged women . Future studies need to address these issues and determine if these short-term benefits can be sustained Fatigue and insomnia are problems for patients with cancer . Research findings show that aerobic exercise decreases cancer-related fatigue . Because patients with cancer who have skeletal muscle wasting may not obtain maximum benefit from aerobic exercise training , exercise programs may need to include resistance training . Thus far , testing exercise as an intervention for fatigue has focused on patients with breast cancer and excluded patients with bone metastasis . There is a need to test the feasibility and effectiveness of exercise for patients with other types of cancer and with bone involvement . The effect of aerobic and strength resistance training on the sleep of patients with cancer has not been tested . A pilot/feasibility study with a r and omized controlled design was conducted to investigate homebased exercise therapy for 24 patients receiving high-dose chemotherapy and autologous peripheral blood stem cell transplantation as treatment for multiple myeloma . None of the patients injured themselves . Because of the small sample size in the feasibility study , the effect of exercise on lean body weight was the only end point that obtained statistical significance . However , the results suggest that an individualized exercise program for patients receiving aggressive treatment for multiple myeloma is feasible and may be effective for decreasing fatigue and mood disturbance , and for improving sleep Exercise participation has been shown to improve cardiovascular fitness and reduce psychological distress  among women receiving chemotherapy and /or radiation . The purpose of this pilot study was to examine the changes in distress and body image , and fitness following exercise participation among 24 women who had been diagnosed with breast cancer within the previous 3 years . The women were r and omly assigned to participate in a 12-week supervised aerobic exercise program in a hospital setting or a wait-list control group . Assessment s of distress and body image were conducted at pre- and post-treatment . Data showed that the women in the exercise group improved significantly in body image ( Physical Condition and Weight Concerns subscales ) vs control group participants at post-treatment . Reductions in distress were also noted in the exercise group , but these were nonsignificant . At post-treatment , there were modest improvements in fitness in the exercise group PURPOSE / OBJECTIVES To examine the effects of a seated exercise program on fatigue and quality of life ( QOL ) in women with metastatic breast cancer . DESIGN R and omized , controlled , longitudinal trial . SETTING Outpatient clinic of a comprehensive cancer center . SAMPLE Convenience sample of 38 women who were beginning outpatient chemotherapy . METHODS Subjects were r and omized to a control or intervention group ; the intervention was performance of a seated exercise program using home videotape three times per week for four cycles of chemotherapy . All subjects completed the Functional Assessment of Chronic Illness Therapy Fatigue Version IV ( FACIT F ) at baseline and at the time of the next three cycles . Subjects were asked to document the frequency , duration , and intensity of all exercise participation on monthly calendars . MAIN RESEARCH VARIABLES Exercise , fatigue , and QOL . FINDINGS 32 subjects , 16 per group , completed the study follow-up . With a mixed modeling approach , total FACIT F scores for the entire sample declined at a significant rate ( p = 0.003 ) beginning with cycle 3 but at a slower rate for the experimental group ( p = 0.02 ) . Fatigue scores indicated less increase and physical well-being subscale scores showed less decline for the experimental group ( p = 0.008 and p = 0.02 , respectively ) . CONCLUSIONS Women with advanced breast cancer r and omized to the seated exercise intervention had a slower decline in total and physical well-being and less increase in fatigue scores starting with the third cycle of chemotherapy . IMPLICATION S FOR NURSING Seated exercise may be a feasible exercise program for women with advanced cancer for controlling fatigue and improving physical well-being PURPOSE / OBJECTIVES To examine the effect of exercise and methylpheni date on fatigue , functional ability , and cognitive function in patients with melanoma . DESIGN Pilot study with comparison to historic controls . SETTING University-based cancer center . SAMPLE 12 patients with melanoma entered and completed the study . The mean age was 44 years . METHOD Eligible patients were recruited before their first dose of interferon-a ( IFN-a ) .  Patients were instructed to take 20 mg sustained-release methylpheni date every morning and follow an aerobic exercise program four days a week for 15 - 30 minutes . Measures included a 12-minute walk , the Schwartz Cancer Fatigue Scale , Trail Maker Forms A and B , Medical Outcomes Study 36 Short Form , body weight , and daily logs . Fatigue scores were compared to usual care historical controls with melanoma receiving only IFN-a . MAIN RESEARCH VARIABLES Fatigue , functional ability , and cognitive function . FINDINGS 66 % adhered to exercise and methylpheni date ; all adhered to exercise . Fatigue was lower for the exercise and methylpheni date group than historic controls . Functional ability increased 6 % for all patients and 9 % for the exercise and methylpheni date group . Cognitive function was stable for the exercise and methylpheni date group . The exercise-only group showed marked cognitive slowing . CONCLUSION The combination of aerobic exercise and methylpheni date may have a positive effect on fatigue , cognitive function , and functional ability . A larger sample size and r and omized trial is needed to more rigorously evaluate the results of exercise and methylpheni date alone or in combination . IMPLICATION S FOR NURSING Although further study is needed , a combination of exercise and methylpheni date may be a practical intervention for patients receiving IFN-a for melanoma PURPOSE Weight gain is a common side effect for women receiving adjuvant chemotherapy  and may have negative long-term implication s for survival . The purpose of this study was to examine the effects of aerobic exercise on weight gain in women with breast cancer receiving adjuvant chemotherapy .  DESCRIPTION OF STUDY Seventy-eight women who had recently received a diagnosis of breast cancer and who were beginning adjuvant chemotherapy  were enrolled in a home-based exercise study during the first four cycles of chemotherapy .  Weight change , body mass index , anorexia , nausea , fatigue , caloric expenditure during exercise , and functional ability were recorded . RESULTS Women who adhered to the exercise program maintained their body weight , while nonexercisers steadily gained weight ( P < .05 ) . There were no differences in incidence or intensity of nausea or anorexia between the exercisers and nonexercisers . Women who exercised over the four cycles of chemotherapy improved their functional ability ( mean 23 % ) compared to the nonexercisers who showed significant declines in functional ability ( mean -15 % ) . CLINICAL IMPLICATION S Exercise may be an effective intervention to minimize weight gain in women with breast cancer who are receiving adjuvant chemotherapy .  Preventing weight gain in these patients may be important in preventing recurrent disease and other comorbidities associated with excess weight We conducted a r and omized controlled trial to determine the effects of a home-based exercise intervention on change in quality of life ( QOL ) in recently resected colorectal cancer survivors , most of whom were receiving adjuvant therapy . Participants were r and omly assigned in a 2:1 ratio to either an  exercise ( n = 69 ) or control ( n = 33 ) group . The exercise group was asked to perform moderate intensity exercise 3 - 5 times per week for 20 - 30 min each time . The primary outcome was change in QOL as measured by the Functional Assessment of Cancer Therapy-Colorectal ( FACT-C ) scale . Adherence in the exercise group was good ( 75.8 % ) but contamination in the control group was problematic ( 51.6 % ) . Intention-to-treat analysis revealed no significant differences between groups for change in the FACT-C ( mean difference , -1.3 ; 95 % CI , -7.8 to 5.1 ; P = 0.679 ) . In an ' on-treatment ' ancillary analysis , we compared participants who decreased versus increased their cardiovascular fitness over the course of the intervention . This analysis revealed significant differences in favour of the increased fitness group for the FACT-C ( mean difference , 6.5 ; 95 % CI , 0.4 - 12.6 ; P = 0.038 ) . These data suggest that increased cardiovascular fitness is associated with improvements in QOL in colorectal cancer survivors but better controlled trials are needed Fatigue and loss of physical performance are frequent problems of cancer patients . In a pilot study , the authors evaluated the feasibility and effects of  aerobic training  in the rehabilitation of cancer patients after completing high dose chemotherapy OBJECTIVES Cancer treatment-related fatigue is a common and disruptive side effect of chemotherapy . Exercise is an intervention proposed to reduce fatigue in cancer patients . The purpose of this study was to describe the patterns of daily fatigue in women with breast cancer who did and did not exercise while receiving the first three cycles of adjuvant chemotherapy .  MATERIAL S AND METHODS Women received instruction to follow an 8-week home-based exercise program and to maintain daily exercise and fatigue diaries . Functional ability ( 12-minute walk ) was measured pretest and post-test . RESULTS Several distinct patterns of fatigue emerged . The most common pattern of fatigue after chemotherapy demonstrated a sharp rise in fatigue . However , several women demonstrated a chaotic pattern with erratic and wide swings in their fatigue throughout the entire study period . Women who adopted exercise experienced fewer days of high fatigue levels and more days of low levels of fatigue for both average and worst levels of fatigue . Women who did not exercise experienced more bad days ( high fatigue ) and fewer good days ( low fatigue ) . CONCLUSIONS Exercise appears to reduce the levels of average and worst fatigue and may help women recognize their pattern of fatigue . Exercise may reduce the intensity of fatigue by reorganizing women 's interpretation of fatigue . Routine clinical assessment and education about fatigue by health professionals can help patients to underst and their pattern of fatigue and may help them to manage the symptom PURPOSE And rogen deprivation therapy is a common treatment in men with prostate cancer that may cause fatigue , functional decline , increased body fatness , and loss of lean body tissue . These physical changes can negatively affect health-related quality of life .  Resistance exercise may help to counter some of these side effects by reducing fatigue , elevating mood , building muscle mass , and reducing body fat . METHODS In a two-site study , 155 men with prostate cancer who were scheduled to receive and rogen deprivation therapy for at least 3 months after recruitment were r and omly assigned to an intervention group that participated in a resistance exercise program three times per week for 12 weeks ( 82 men ) or to a waiting list control group ( 73 men ) . The primary outcomes were fatigue and disease-specific quality of life as assessed by self-reported question naires after 12 weeks . Secondary outcomes were muscular fitness and body composition . RESULTS Men assigned to resistance exercise had less interference from fatigue on activities of daily living ( P = .002 ) and higher quality of life ( P = .001 ) than men in the control group . Men in the intervention group demonstrated higher levels of upper body ( P = .009 ) and lower body ( P < .001 ) muscular fitness than men in the control group . The 12-week resistance exercise intervention did not improve body composition as measured by changes in body weight , body mass index , waist circumference , or subcutaneous skinfolds . CONCLUSION Resistance exercise reduces fatigue and improves quality of life and muscular fitness in men with prostate cancer receiving and rogen deprivation therapy .  This form of exercise can be an important component of supportive care for these patients PURPOSE The efficacy of a home-based physical activity ( PA ) intervention for early-stage breast cancer patients was evaluated in a r and omized controlled trial . PATIENTS AND METHODS Eighty-six sedentary women ( mean age , 53.14 years ; st and ard deviation , 9.70 years ) who had completed treatment for stage 0 to II breast cancer were r and omly assigned to a PA or contact control group . Participants in the PA group received 12 weeks of PA counseling ( based on the Transtheoretical Model ) delivered via telephone , as well as weekly exercise tip sheets . Assessment s were conducted at baseline , after treatment ( 12 weeks ) , and 6 and 9 month after baseline follow-ups . The post-treatment outcomes are reported here . RESULTS Analyses showed that , after treatment , the PA group reported significantly more total minutes of PA , more minutes of moderate-intensity PA , and higher energy expenditure per week than controls . The PA group also out-performed controls on a field test of fitness . Changes in PA were not reflected in objective activity monitoring . The PA group was more likely than controls to progress in motivational readiness for PA and to meet PA guidelines . No significant group differences were found in body mass index and percent body fat . Post-treatment group comparisons revealed significant improvements in vigor and a reduction in fatigue in the PA group . There was a positive trend in intervention effects on overall mood and body esteem . CONCLUSION The intervention successfully increased PA and improved fitness and specific aspects of psychological well-being among early-stage breast cancer patients . The success of a home-based PA intervention has important implication s for promoting recovery in this population PURPOSE To evaluate the effectiveness of a supervised home-based flexible training program on cardiorespiratory fitness ( CRF ) , mental distress , and health-related quality of life ( HRQOL ) parameters in young and middle-aged cancer patients shortly after curative chemotherapy . PATIENTS AND METHODS One hundred eleven patients age 18 to 50 years who had received chemotherapy for lymphomas or breast , gynecologic , or testicular cancer completed the trial . These patients were r and omly allocated to either an intervention group ( n = 59 ) , which underwent a 14-week training program , or a control group ( n = 52 ) that received st and ard care . Primary outcome was change in CRF , as determined by Astr and -Rhyming indirect bicycle ergometer test ( maximum oxygen uptake [ VO(2max ) ] ) , between baseline ( T0 ) and follow-up ( T1 ) . Secondary outcomes were mental distress , as assessed by the Hospital Anxiety and Depression Scale , and HRQOL , as assessed by the European Organisation for Research and Treatment of Cancer Core Quality of Life Question naire . Two-way analysis of covariance was used to analyze changes from T0 to T1 . RESULTS VO(2max ) increased by 6.4 mL/kg(-1)/min(-1 ) in patients in the intervention group and by 3.1 mL/kg(-1)/min(-1 ) in patients in the control group ( P < .01 ) . The fatigue score decreased by 17.0 points in the control group compared with only 5.8 points in the intervention group ( P < .01 ) . There were no intergroup differences in mental distress or HRQOL . CONCLUSION A supervised , home-based , flexible training program has significant effect on CRF in young and middle-aged cancer patients shortly after curative chemotherapy , but it has no favorable effect on patients ' experience of fatigue , mental distress , or HRQOL Physical exercise is becoming an accepted part of therapy for many patients with cancer .  Exercise may alleviate patients ' fatigue and improve physical performance and psychological outlook . Much of the research is limited to women with breast cancer and excludes patients with bone metastases . This article reports on the authors ' work in facilitating exercise adherence for patients with multiple myeloma ( MM ) and bone lesions while they were enrolled in a feasibility/pilot exercise study as they were receiving treatment for their disease in an outpatient treatment program . The exercise program for these patients receiving high-dose chemotherapy and stem cell transplantation consisted of aerobic and strength-building components . The program was home based , and patients performed exercises without direct supervision . On average , the patients completed the six-month exercise prescription 75 % of the time . Overall trends showed that all 14 patients in the exercise group  improved in several areas of testing , and the test results of all 10 patients in the usual-care group declined . Flexibility and simplicity are essential when design ing exercise programs for patients , and encouragement and support also are needed to help patients adhere to prescribed exercise Background : Fatigue has a significant impact on the quality of life ( QOL ) of cancer patients . Recent research has suggested that physical activity can reduce fatigue in patients receiving active cancer treatment . In this project , we examined the impact that participation in a r and omized controlled trial of a multidisciplinary intervention design ed to impact overall QOL had on fatigue for advanced cancer patients actively receiving treatment . Methods : Patients with newly diagnosed cancer were r and omly assigned to an 8-session structured multidisciplinary intervention or a st and ard-care arm at the beginning of their course of radiotherapy ( RT ) design ed to impact QOL . Ninety-minute sessions were led by either a psychiatrist or psychologist , collaborating with a nurse , physical therapist , chaplain , or social worker , depending on the session 's theme . The fatigue assessment s used in this trial included the Linear Analogue Self Assessment ( LASA ) , the Profile of Mood States ( POMS ) , Spielberger 's State-Trait Anxiety Inventory ( STAI ) , and the Symptom Distress Scale ( SDS ) . Results : There were 115 participants enrolled and the 2 r and omization arms were well balanced in terms of baseline characteristics and treatment received except for increased commuting distance for the patients in the intervention arm ( P = 0.042 ) . Most of scores indicated less fatigue ( higher score ) in the st and ard treatment group , but there were no statistically significant differences found at baseline and weeks 4 , 8 , and 27 except for SDS at week 8 ( P = 0.018 ) with less patients reporting significant fatigue in the st and ard treatment arm . For the entire participant population , fatigue levels initially worsened with radiotherapy , stabilized at week 8 , and returned to baseline by week 27 . Disease site , chemotherapy use , and radiotherapy dose did not have a significant impact on fatigue levels . Conclusions : Radiotherapy initially caused a worsening of fatigue but with time fatigue levels returned to baseline . Clinical ly , this structured multidisciplinary intervention had no impact on fatigue , and there was the suggestion the multiple sessions may have contributed to worse fatigue during active cancer treatment The effect of a 10-week aerobic interval-training cycle ergometer protocol on the functional capacity ( VO2Lmax ) of 45 women receiving chemotherapy for treatment of Stage II breast cancer was studied . Subjects were stratified by baseline functional capacity ( ± 1 MET ) and r and omized to experimental ( EX ) , placebo ( PL ) , and control ( CO ) groups . EX subjects completed a 10-week , 3 times/week exercise training program ; PL subjects participated in 10 weeks of nonaerobic stretching and flexibility exercises ; the CO group maintained normal activities . The EX group showed significant , p < .05 , improvement on pre- to posttest VO2Lmax as well as workload and test time compared to the PL and CO groups . The interval-training exercise intervention was effective in improving the functional capacity of Stage II breast cancer patients on adjuvant chemotherapy Physical exercise has been shown to enhance quality of life ( QOL ) in cancer survivors using pretest-posttest design s and compared to usual care ( i.e. no intervention ) . In the present study , we conducted a r and omized controlled trial to determine if exercise could improve QOL in cancer survivors beyond the known benefits of group psychotherapy ( GP ) . We matched 22 GP classes ( N=108 ) on content and then r and omly assigned 11 ( n=48 ) to GP alone and 11 ( n=60 ) to GP plus home-based , moderate-intensity exercise ( GP+EX ) . Participants completed a physical fitness test and QOL measures ( e.g. Functional Assessment of Cancer Therapy scales ) at the beginning and end of GP classes ( about 10 weeks ) . We had excellent recruitment ( 81 % ) , retention ( 89 % ) , and adherence ( 84 % ) rates and a modest contamination ( 22 % ) rate . Using intention-to-treat repeated measures analyses of variance , we found significant Time by Condition interactions for functional well-being , fatigue , and sum of skinfolds . We also found borderline significant interactions for physical well-being , satisfaction with life , and flexibility . All interactions favored the GP+EX condition . We conclude that a home-based , moderate intensity exercise program may im-prove QOL in cancer survivors beyond the benefits of GP , particularly in relation to physical and functional well-being Fatigue is a common and often severe problem in cancer patients undergoing chemotherapy .  The authors postulated that physical activity training can reduce the intensity of fatigue in this group of patients Fatigue is the most prevalent and debilitating symptom experienced by breast cancer patients receiving adjuvant chemotherapy or radiation therapy and few evidence -based treatments are available to manage this distressing side-effect . The purpose of this multi-institutional r and omized controlled trial was to determine the effects of exercise on fatigue levels during treatment for breast cancer . Sedentary women ( N=119 ) with Stage 0-III breast cancer receiving outpatient adjuvant chemotherapy or radiation therapy were r and omized to a home-based moderate-intensity walking exercise program or to usual care for the duration of their cancer treatment . Of participants r and omized to exercise , 72 % adhered to the exercise prescription ; 61 % of the usual care group adhered . The intention-to-treat analysis revealed no group differences in part because of a dilution of treatment effect as 39 % of the usual care group exercised and 28 % of the exercise group did not . When exercise participation was considered using the data analysis method of instrumental variables with principal stratification , a clinical ly important and statistically significant ( p=0.03 ) effect of exercise on pretest-to-posttest change in fatigue levels was demonstrated . Adherence to a home-based moderate-intensity walking exercise program may effectively mitigate the high levels of fatigue prevalent during cancer treatment
