Aerobic and Strength Training Exercise in Improving Fitness and Arm Health During and After Radiation Therapy in Patients With Stage II-III Breast Cancer

Aerobic and Strength Training Exercise in Improving Fitness and Arm Health During and After Radiation Therapy in Patients With Stage II-III Breast Cancer

Can Aerobic and Strength Training Exercise Initiated During and Continued After Radiation Therapy for Breast Cancer Improve Fitness and Arm Health 1 Year Later?

This randomized pilot phase I/II trial studies how well aerobic and strength training exercise works in improving fitness and arm health during and after radiation therapy consisting of regional nodal radiation in patients with stage II-III breast cancer. Aerobic and strength training exercise training during and after radiation therapy may reduce treatment related toxicities and improve adherence to exercise long term in patients with breast cancer.

PRIMARY OBJECTIVES: I. To determine the feasibility of conducting an exercise program during and after radiation therapy and to determine what percent of patients will complete the exercise program. (Pilot) II. To determine the percent increase in fitness as measured by the 6 minute walk test in women receiving radiation therapy for breast cancer randomized to an exercise program at 1 year. (Phase II) SECONDARY OBJECTIVES: I. Percent adherence to exercise at 1 year as measured by the International Physical Activity Questionnaire and exercise logs. II. Subjective arm health at 1 year as measured by Functional Assessment of Cancer Therapy Questionnaire for Breast Cancer version 4 (FACT-B+4). III. Arm lymphedema at 1 year as measured by arm circumference. IV. Arm range of motion at 1 year as measured by goniometry. V. Quality of life at 1 year as measured by FACT-B+4. VI. Percent increase in arm strength as measured by one repetition maximum at 1 year. VII. Change in weight and body mass index (BMI) 1 year after completion of radiation. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive usual care for 6 weeks during radiation therapy and for 12 weeks after completion of radiation therapy. ARM II: Patients undergo a supervised aerobic and strength training exercise session over 40-60 minutes 3 times weekly for 6 weeks during radiation therapy and for 12 weeks after completion of radiation therapy. After completion of study, patients are followed up at 1 year.

Stage II Breast Cancer, Stage IIA Breast Cancer, Stage IIB Breast Cancer, Stage III Breast Cancer, Stage IIIA Breast Cancer, Stage IIIB Breast Cancer, Stage IIIC Breast Cancer

Patients receive usual care for 6 weeks during radiation therapy and for 12 weeks after completion of radiation therapy.

Patients undergo a supervised aerobic and strength training exercise session over 40-60 minutes 3 times weekly for 6 weeks during radiation therapy and for 12 weeks after completion of radiation therapy.

Number of participants who complete 70% of all exercise sessions throughout the supervised program during and after radiation therapy (Pilot)

determine the feasibility of conducting an exercise program during and after radiation therapy and to determine what percent of patients will complete the exercise program.

Percent increase in fitness as measured by the 6 minute walk test in patients randomized to exercise program (Phase II)

Lymphedema will be classified into 3 stages. Stage I edema is reversible and characterized by pitting edema, increase in arm girth, and heaviness. Stage II is characterized by a spongy consistency of the arm without pitting edema. Stage III is the most advanced stage, lymphostatic elephantiasis

BMI will be measured to evaluate body composition using the metric formula weight (kg)/ height 2 (m2).

Percent adherence to exercise as measured by the International Physical Activity Questionnaire and exercise logs

Duration of exercise will be calculated based on questionnaire and exercise log. Percentage of exercise adherence at 1-year follow-up will be compared between two groups. Generalized linear models will be utilized to model follow-up as a function of baseline and group.

The FACT B + 4 has been shown to have good internal consistency and stability. It is a 40 item Likert scale questionnaire with subscales (0 - 4) for physical well being, social/family well being, emotional well being, function well being, and 4 specific questions related to arm symptoms.
