Effects of yoga program on quality of life and affect in early breast cancer patients undergoing adjuvant radiotherapy: a randomized controlled trial.
ABSTRACT This study compares the effects of an integrated yoga program with brief supportive therapy in breast cancer outpatients undergoing adjuvant radiotherapy at a cancer centre.
Eighty-eight stage II and III breast cancer outpatients were randomly assigned to receive yoga (n = 44) or brief supportive therapy (n = 44) prior to their radiotherapy treatment. Intervention consisted of yoga sessions lasting 60 min daily while the control group was imparted supportive therapy once in 10 days. Assessments included European Organization for Research in the Treatment of Cancer-Quality of Life (EORTCQoL C30) functional scales and Positive and Negative Affect Schedule (PANAS). Assessments were done at baseline and after 6 weeks of radiotherapy treatment.
An intention to treat GLM repeated measures ANOVA showed significant difference across groups over time for positive affect, negative affect and emotional function and social function. There was significant improvement in positive affect (ES = 0.59, p = 0.007, 95%CI 1.25 to 7.8), emotional function (ES = 0.71, p = 0.001, 95%CI 6.45 to 25.33) and cognitive function (ES = 0.48, p = 0.03, 95%CI 1.2 to 18.5), and decrease in negative affect (ES = 0.84, p<0.001, 95%CI -13.4 to -4.4) in the yoga group as compared to controls. There was a significant positive correlation between positive affect with role function, social function and global quality of life. There was a significant negative correlation between negative affect with physical function, role function, emotional function and social function.
The results suggest a possible role for yoga to improve quality of life and affect in breast cancer outpatients.

ABSTRACT: Sixty percent of cancer survivors are 65years of age or older. Cancer and its treatments lead to cancer-related fatigue and many other side effects, in turn, creating substantial global side-effect burden (total burden from all side effects) which, ultimately, compromises functional independence and quality of life. Various modes of exercise, such as yoga, reduce cancer-related fatigue and global side-effect burden in younger cancer survivors, but no studies have specifically examined the effects of yoga on older cancer survivors. The purpose of this study was to assess the effects of a 4-week yoga intervention (Yoga for Cancer Survivors: YOCAS©®) on overall cancer-related fatigue, and due to its multidimensional nature, the subdomains of cancer-related fatigue (general, physical, emotional, and mental) and global side-effect burden in older cancer survivors. We conducted a secondary analysis on data from a multicenter phase III randomized controlled clinical trial with 2 arms (standard care and standard care plus a 4-week YOCAS©® intervention). The sample for this secondary analysis was 97 older cancer survivors (≥60years of age), between 2months and 2years post-treatment, who participated in the original trial. Participants in the YOCAS©® intervention arm reported significantly lower cancer-related fatigue, physical fatigue, mental fatigue, and global side-effect burden than participants in the standard care arm following the 4-week intervention period (p<0.05). YOCAS©® is an effective standardized yoga intervention for reducing cancer-related fatigue, physical fatigue, mental fatigue, and global side-effect burden among older cancer survivors.

ABSTRACT: Previous studies have demonstrated health benefits of mindfulness-based interventions (MBIs) among cancer patients. While sustained mindfulness practice is an integral part of MBIs, few studies have examined the role of home practice on intervention outcomes. Also, little is known about characteristics of those who attend more classes and practice more yoga and meditation. Hence, this study investigated predictors and outcomes of engagement in a Mindfulness-Based Cancer Recovery (MBCR) program. Questionnaire data and home practice logs of 38 breast cancer survivors were collected before and after MBCR. A range of demographic, personality, and symptom-related factors were measured. Correlations and regression analyses were conducted. Only greater baseline anxiety was correlated with more home meditation practice (p p p p p p p p p Directionality and clinical significance of these changes need to be further investigated.Mindfulness 01/2015; DOI:10.1007/s12671-014-0381-4

ABSTRACT: A growing number of randomized controlled trials (RCTs) have investigated the therapeutic value of yoga interventions. This bibliometric analysis aimed to provide a comprehensive review of the characteristics of the totality of available randomized yoga trials.BMC Complementary and Alternative Medicine 09/2014; 14(1):328.
