Trial of Exercise to Reduce Cancer Related Fatigue in Breast Cancer

Cancer related fatigue (CRF) is a common and debilitating side effect of radiotherapy in breast cancer patients. Physical activity interventions can attenuate CRF. The proposed study is a randomized, controlled trial (RCT) of exercise of structured moderate-intensity exercise intervention, delivered concurrently with radiotherapy, to reduce CRF and improve health-related quality of life among breast cancer patients. Eighty women with breast cancer scheduled to receive radiation therapy at Hackensack University Medical Center (HUMC) will be randomized to one of the two trial arms:1) a facility-based aerobic exercise utilizing a portable stationary pedal exerciser; or 2) a control group. Intervention arm participants will exercise at the hospital either before or after their radiation treatment. Assessments will be conducted at baseline, 4 weeks into radiation course, and at 4-week follow-up visit. The outcome variables are CRF, biomarkers of inflammation, and health-related quality of life (QOL). The study will provide preliminary evidence on whether a short-term moderate-intensity exercise intervention might be effective in reducing CRF in women undergoing radiotherapy for breast cancer, and whether this effect is mediated by inflammation.
