Exercise and Diet Counseling Program in Improving Quality of Life in Stage I-III Breast Cancer Survivors

Exercise and Diet Counseling Program in Improving Quality of Life in Stage I-III Breast Cancer Survivors

This trial studies the benefits of an exercise and diet counseling program in improving quality of life in stage I-III breast cancer survivors. Exercise and diet counseling may help improve weight loss and relevant clinical and patient-reported outcomes in overweight or obese breast cancer survivors.

PRIMARY OBJECTIVES: I. To determine the feasibility of delivering a community-based, comprehensive lifestyle weight management (LWM) intervention to 20 overweight or obese breast cancer (BC) survivors. II. Explore preliminary efficacy of the community-based, comprehensive LWM intervention for producing meaningful improvements in select clinically-relevant anthropometric, fitness, functional, and patient-reported outcomes in BC survivors. III. Provide the effect size estimates necessary to inform the design of a subsequent R01 application addressing a large scale, optimally powered, randomized controlled, community-based LWM comparative efficacy intervention trial targeting weight loss in BC survivors. OUTLINE: Patients undergo aerobic exercise over 10-30 minutes and resistance exercise comprising 1-3 sets of 8-12 repetitions of 10 different exercises over 1 hour for 24 weeks. Patients also receive behavioral activity counseling once a week and nutritional counseling over 30 minutes for 10 sessions after center-based exercise sessions during months 1-2. After completion of study, patients are followed up at 3 and 6 months.

Assessed with the 400-meter walk test. Will be analyzed using paired samples t-tests. Statistical significance will be assumed at p =< 0.05, and results will be based on two-tailed statistical tests. Mean change from baseline, paired sample t-test, and effect size estimates will be calculated for each outcome measure. Analyses will be conducted using the intent-to-treat principle to account for missing data with the last observation carried forward (LOCF) approach, used to impute change across time to be zero. Additionally, effect sizes (Cohen?s d) will be calculated by taking the mean difference and dividing by the pooled standard deviation to determine the magnitude of differences observed for each outcome.

The SF-12 questionnaire is a 12 -item scale that assesses the Physical (PCS) and Mental Health (MCS) composite summary scales composed of 6 items each on a 5-point rating scale. PCS and MCS scores range from 0-30 with higher scores indicating more favorable outcomes.

The Brief Fatigue Inventory is a 9-item scale scored on an 11-point rating scale ranging from 0 (no fatigue) to 10 (as bad as you can imagine). Higher scores represent greater levels of fatigue. In this form, there are 5 overarching questions. The first one asks, "Have you felt unusually tired or fatigued in the last week?" which is simply a Yes or No response. The next 4 questions then have answers in terms of a scale. The next 3 have the following sliding scale: 0= No Fatigue, 10= As bad as you can imagine, with 1-9 each representing intermediate responses. For the last question, the scale is: 0= Does not interfere, 10= Completely interferes, with 1-9 representing individual intermediate responses.
