A Comprehensive Oncology Rehabilitation and Exercise (CORE) Program Among Breast Cancer Survivors

Enrollment: The study team will recruit 72 newly diagnosed stage I-III breast cancer survivors to participate in a 24-week randomized controlled trial. Participants will be randomized to CORE or SOC in a 2:1 ratio, stratified by adherence to national physical activity guidelines. Exercise Intervention: Participants randomized to standard of care will be instructed to continue their typical lifestyle activity. Participants randomized to CORE will complete an in-clinic assessment consisting of the PROMIS Physical Function and Godin surveys to identify the appropriate pathway for triage. Results from the questionnaires will be used to triage participants into one of three groups: 1. Physical Medicine \& Rehabilitation (PM\&R): This rehab service is aimed at improving complex and acute functional deficits. Participants with a T-score \< 40 on PROMIS will be triaged to PM\&R, regardless of current exercise engagement. 2. Personal Optimism With Exercise Recovery (POWER): POWER is our institution's exercise oncology program. POWER is aimed at improving mild functional deficits and physical deconditioning. Participants with a T-score of 40-50 on PROMIS who are not meeting activity guidelines, will be triaged to POWER. Participants with a T-score of ≥ 40 who are meeting activity guidelines, may choose to participate in POWER or be re-triaged to Exercise Self-Management. 3. Exercise Self-Management: This arm is aimed for participants who are fit and free of functional deficits and impaired physical conditioning. Participants with a T-score of ≥ 51 on PROMIS and currently meeting activity guidelines will be triaged to this group. They may choose to participate in POWER. Assessments: Five assessment methods will be collected over three time points: (1) Post-Diagnosis/Pre-Surgery, (2) Post-Surgery, and (3) 24-weeks Post-Surgery.
