    Input: 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 This study examined the effect of an integrated yoga programme on chemotherapy-related nausea and emesis in early operable breast cancer out patients . Sixty-two subjects were r and omly allocated to receive yoga ( n = 28 ) or supportive therapy intervention ( n = 34 ) during the course of their chemotherapy . Both groups had similar socio-demographic and medical characteristics . Intervention consisted of both supervised and home practice of yoga sessions lasting for 60 min daily , while the control group received supportive therapy and coping preparation during their hospital visits over a complete course of chemotherapy . The primary outcome measure was the Morrow Assessment of Nausea and Emesis ( MANE ) assessed after the fourth cycle of chemotherapy . Secondary outcomes included measures for anxiety , depression , quality of life , distressful symptoms and treatment-related toxicity assessed before and during the course of chemotherapy . Following yoga , there was a significant decrease in post-chemotherapy-induced nausea frequency ( P = 0.01 ) and nausea intensity ( P = 0.01 ) , and intensity of anticipatory nausea ( P = 0.01 ) and anticipatory vomiting ( P = 0.05 ) as compared with the control group . There was a significant positive correlation between MANE scores and anxiety , depression and distressful symptoms . In conclusion , the results suggest a possible use for stress reduction interventions such as yoga in complementing conventional antiemetics to manage chemotherapy-related nausea and emesis To compare the effectiveness of individual support , group rehabilitation and a combination of the two in improving health-related quality of life ( HRQOL ) and psychological well-being in cancer patients during 24 months after diagnosis , as compared with st and ard care ( SC ) . Furthermore , to compare the study sample and a r and om sample of the Swedish population with regard to HRQOL . A total of 481 consecutive patients , newly diagnosed with cancer , were r and omly assigned to one of the four alternatives . Data on HRQOL and psychological well-being were collected at baseline and after 3 , 6 , 12 and 24 months . The interventions did not improve HRQOL or psychological well-being , as compared with SC . At 3 months , the study sample reported an HRQOL comparable with the normal population . Many cancer patients are able to manage their cancer-related concerns with the support available from SC . However , it is reasonable to assume that the findings suffer from a lack of data from especially vulnerable patients and a possible Hawthorne effect . It can not be concluded that cancer patients have no need for additional psychosocial interventions . Future projects should include screening and target interventions for those at risk for significant and prolonged psychological distress Background Current method ological guidelines provide advice about the assessment of sub-group analysis within RCTs , but do not specify explicit criteria for assessment . Our objective was to provide research ers with a set of criteria that will facilitate the grading of evidence for moderators , in systematic review s. Method We developed a set of criteria from method ological manuscripts ( n = 18 ) using snowballing technique , and electronic data base search es . Criteria were review ed by an international Delphi panel ( n = 21 ) , comprising authors who have published method ological papers in this area , and research ers who have been active in the study of sub-group analysis in RCTs . We used the Research ANd Development/University of California Los Angeles appropriateness method to assess consensus on the quantitative data . Free responses were coded for consensus and disagreement . In a subsequent round additional criteria were extracted from the Cochrane Review ers ' H and book , and the process was repeated . Results The recommendations are that meta-analysts report both confirmatory and exploratory findings for sub-groups analysis . Confirmatory findings must only come from studies in which a specific theory/ evidence based a-priori statement is made . Exploratory findings may be used to inform future/subsequent trials . However , for inclusion in the meta- analysis of moderators , the following additional criteria should be applied to each study : Baseline factors should be measured prior to r and omisation , measurement of baseline factors should be of adequate reliability and validity , and a specific test of the interaction between baseline factors and interventions must be presented . Conclusions There is consensus from a group of 21 international experts that method ological criteria to assess moderators within systematic review s of RCTs is both timely and necessary . The consensus from the experts result ed in five criteria divided into two groups when synthesis ing evidence : confirmatory findings to support hypotheses about moderators and exploratory findings to inform future research . These recommendations are discussed in reference to previous recommendations for evaluating and reporting moderator studies OBJECTIVE To determine the effect of exercise on quality of life in ( a ) a r and omized controlled trial of exercise among recently diagnosed breast cancer survivors undergoing adjuvant therapy and ( b ) a similar trial among post-treatment survivors . METHODS Fifty newly diagnosed breast cancer survivors were recruited through a hospital-based tumor registry and r and omized to a 6-month , home-based exercise program ( n=25 ) or a usual care group ( n=25 ) . In a separate trial , 75 post-treatment survivors were r and omized to a 6-month , supervised exercise intervention ( n=37 ) or to usual care ( n=38 ) . Participants in both studies completed measures of happiness , depressive symptoms , anxiety , stress , self-esteem , and quality of life at baseline and 6 months . RESULTS Forty-five participants completed the trial for newly diagnosed survivors and 67 completed the trial for post-treatment survivors . Good adherence was observed in both studies . Baseline quality of life was similar for both studies on most measures . Exercise was not associated with quality of life benefits in the full sample of either study ; however exercise was associated with improved social functioning among post-treatment survivors who reported low social functioning at baseline ( p<0.05 ) . CONCLUSIONS Exercise did not affect quality of life in either recently diagnosed or post-treatment breast cancer survivors ; however this may be due in part to relatively high baseline functioning among participants in both studies . Strategies for future research include limiting enrollment to survivors who report reduced quality of life on screening question naires and targeting survivor subgroups known to be at particular risk for quality of life impairment PURPOSE Interventions to increase physical activity among breast cancer survivors are needed to improve health and quality of life and possibly to reduce the risk of disease recurrence and early mortality . Therefore , we report the feasibility and preliminary outcomes of a pilot r and omized trial design ed to increase physical activity in sedentary breast cancer survivors receiving hormone therapy . METHODS Forty-one sedentary women on estrogen receptor modulators or aromatase inhibitors for stage I , II , or IIIA breast cancer were r and omly assigned to receive a 12-wk multidisciplinary physical activity behavior change intervention or usual care . RESULTS Recruitment was 34 % , intervention adherence was 99 % , and complete follow-up data were obtained on 93 % . Most participants ( 93 % ) were white with mean age of 53 + /- 9 yr . Differences favoring the intervention group were noted for accelerometer physical activity counts ( mean difference = 72,103 ; 95 % confidence interval ( CI ) = 25,383 - 119,000 ; effect size ( d ) = 1.02 ; P = 0.004 ) , aerobic fitness ( mean difference = 2.9 ; 95 % CI = -0.1 to 5.8 ; d = 0.64 ; P = 0.058 ) , back/leg muscle strength ( mean difference = 12.3 ; 95 % CI = 0.4 - 15.9 ; d = 0.81 ; P = 0.017 ) , waist-to-hip ratio ( mean difference = -0.05 ; 95 % CI = -0.01 to -0.08 ; d = -0.77 ; P = 0.018 ) , and social well-being ( mean difference = 2.0 ; 95 % CI = 0.3 - 3.8 ; d = 0.76 ; P = 0.03 ) . However , the intervention group also reported a greater increase in joint stiffness ( mean difference = 1.1 ; 95 % CI = 0.1 - 2.2 ; d = 0.70 ; P = 0.04 ) . CONCLUSIONS A behavior change intervention for breast cancer survivors based on the social cognitive theory is feasible and results in potentially meaningful improvements in physical activity and selected health outcomes . Confirmation in a larger study is warranted 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 Objective To assess the effect of a multimodal group exercise intervention , as an adjunct to conventional care , on fatigue , physical capacity , general wellbeing , physical activity , and quality of life in patients with cancer who were undergoing adjuvant chemotherapy or treatment for advanced disease . Design R and omised controlled trial . Setting Two university hospitals in Copenhagen , Denmark . Participants 269 patients with cancer ; 73 men , 196 women , mean age 47 years ( range 20 - 65 ) representing 21 diagnoses . Main exclusion criteria were brain or bone metastases . 235 patients completed follow-up . Intervention Supervised exercise comprising high intensity cardiovascular and resistance training , relaxation and body awareness training , massage , nine hours weekly for six weeks in addition to conventional care , compared with conventional care . Main outcome measures European Organization for Research and Treatment of Cancer Quality of Life Question naire ( EORTC QLQ-C30 ) , Medical Outcomes Study Short Form ( MOS SF-36 ) , Leisure Time Physical Activity Question naire , muscular strength ( one repetition maximum ) , maximum oxygen consumption ( Vo2max ) . Statistical methods The general linear model was used for continuous outcome while analysis of associates between categorical outcomes was performed as analysis of marginal homogeneity in contingency tables . Results Adjusted for baseline score , disease , and demographic covariates , the intervention group showed an estimated improvement at six weeks for the primary outcome , fatigue , of −6.6 points ( 95 % confidence interval −12.3 to −0.9 , P=0.02 ; effect size=0.33 , 0.04 to 0.61 ) . Significant effects were seen on vitality ( effect size 0.55 , 95 % CI 0.27 to 0.82 ) , physical functioning ( 0.37 , 0.09 to 0.65 ) , role physical ( 0.37 , 0.10 to 0.64 ) , role emotional ( 0.32 , 0.05 to 0.59 ) , and mental health ( 0.28 , 0.02 to 0.56 ) scores . Improvement was noted in physical capacity : estimated mean difference between groups for maximum oxygen consumption was 0.16 l/min ( 95 % CI 0.1 to 0.2 , P<0.0001 ) and for muscular strength ( leg press ) was 29.7 kg ( 23.4 to 34.9 , P<0.0001 ) . No significant effect was seen on global health status/ quality of life . Conclusion A supervised multimodal exercise intervention including high and low intensity components was feasible and could safely be used in patients with various cancers who were receiving adjuvant chemotherapy or treatment for advanced disease . The intervention reduced fatigue and improved vitality , aerobic capacity , muscular strength , and physical and functional activity , and emotional wellbeing , but not quality of life .
