Study Overview
Brief Summary
Radiation therapy (RT) is often used to treat breast cancer. RT combined with breast surgery is associated with better outcomes in early stage breast cancer compared to surgery alone. Fatigue is one of the most important side effects of RT because it can decrease patients' quality of life.
Studies found that physical activity (PA) may help to improve quality of life in cancer survivors. PA has been reported to lower fatigue, anxiety, and depression. Physical inactivity over a long period of time may lead to rapid energy and physical function loss.
PA intervention studies in patients undergoing RT have included mostly White patients. There is no evidence on African American patients undergoing RT. The purpose of this study is to examine the efficacy of a structured, moderate-intensity, aerobic exercise program in reducing cancer-related fatigue in African Americans undergoing RT for localized breast cancer.
Detailed Description
* Purpose of project (one or two sentences): The objective of this study is to examine the efficacy of a structured, moderate-intensity aerobic exercise program in reducing cancer-related fatigue in African Americans undergoing RT for localized breast cancer.
- * Study design (for example, hypothesis, research questions, standard and experimental procedures/drugs/devices or equipment, etc.):
This is a randomized clinical trial to determine the efficacy of a structured, moderate-intensity aerobic exercise program in reducing cancer-related fatigue. The study occurs at a single-center setting. There are 30 breast cancer patient/subjects in all, a portion of whom (n=15) will undergo a structured, moderate-intensity aerobic exercise delivered via a stationary cycling device (peddlers).
The study duration would be 12 months, and the administration of the study would be 8 weeks. The exercise program will be carried out at Washington Hospital Center while they wait for radiation therapy treatments.
- * Rationale and justification for study (i.e. historical background, investigator's personal experience, pertinent medical literature, etc.): Given the widespread use of RT for treatment of early stage breast cancers, and the identification of fatigue as an important side-effect of RT, it is important to test interventions that can reduce fatigue and improve the health-related quality of life (HRQOL) among survivors. PA interventions have been shown to improve quality of life and reduce fatigue in cancer patients undergoing RT. However, most studies on PA in RT-related fatigue and HRQOL have been conducted among Whites and evidence on the efficacy of PA interventions in African Americans is lacking. Additionally, the timing of introduction of PA with respect to the RT timeline is also unclear. Finally, although preliminary studies suggest that fatigue might be related to inflammation, it is not clear whether the effect of PA on fatigue is associated with changes in inflammatory biomarkers. The purpose of this study is to test the efficacy of a structured PA intervention in reducing cancer-related fatigue among African American patients undergoing RT for breast cancer.

Arms & Interventions
Physical activity
An 8-week structured, moderate-intensity aerobic training exercise regimen concurrent with their radiation therapy (N=15),
Intervention: Physical Activity (Other)
Control
Patients will continue with usual care, which includes radiation treatment.
Outcomes
Primary Outcomes
Reduce cancer-related fatigue
Time Frame: 8 weeks
Fatigue Cancer-related fatigue will be determined using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) survey instrument. The FACIT-Fatigue is a 13-item subscale developed to identify a finite set of concerns specific to fatigue. The responses to the 13 items on the FACIT fatigue questionnaire are each measured on a 4-point Likert scale. Thus, the total score ranges from 0 to 52. The FACIT-Fatigue scale has been validated in patients with cancer and showed excellent internal consistency and reliability.
Secondary Outcomes
- Increase quality of life(8 weeks)
