Abstract PO2-11-07: Early Integration of Exercise into Breast Cancer Care: The MSK Healthy Living Program

Abstract Background: In patients with early-stage breast cancer, quality of life (QoL) worsens within 3-6 months following diagnosis. Physical activity (PA) can mitigate the adverse effects of treatment and improve QoL, and low PA level is associated with cancer recurrence and mortality. However, PA interventions are not included in standard cancer care. Early intervention to increase PA levels may improve QoL during active cancer therapy. The Healthy Living Program (HLP) at Memorial Sloan Kettering Cancer Center (MSK) is a lifestyle and survivorship program that engages early-stage breast cancer patients at the time of diagnosis using lifestyle risk stratification and matched referrals. We investigated whether early exercise intervention through the MSK HLP impacts QoL within the first months after cancer diagnosis. Methods: At the time of diagnosis, patients complete a lifestyle questionnaire (LQ), which is a composite of validated instruments, including the Godin Leisure Time Exercise Questionnaire (GLTEQ). Patients not meeting PA guidelines per the GLTEQ are offered a referral to an exercise physiologist (EP). The EP creates an individualized, home-based exercise program using the FITT Principle (Frequency, Intensity, Time, and Type). Patients meet with the EP every 4 weeks for 16 weeks; if exercise recommendations continue to be unmet, the program is extended. The Functional Assessment of Cancer Therapy-Breast (FACT-B) and 36-Item Short Form Survey Instrument (SF-36) were completed at baseline and the 16-week follow-up. Results: 252 patients enrolled between April 2020 – February 2023, of whom 92 volunteered to complete the QoL assessments. Median age was 53 years range 23-84; 12/252 (13.0%) of patients had ductal carcinoma in situ, 60/252 (65.2%) had Stage 1 disease, 17/252 (18.5%) had Stage 2 disease, and 3/252 (3.1%) had Stage 3 disease. 29/252 (31.5%) received chemotherapy, 62/252 (67.4%) received radiation, and 79/252 (85.9%) received hormone therapy. The mean baseline FACT scores were FACT-B: 116, FACT-G: 87, and FACT-B Trial Outcome Index (TOI): 73. At the 16-week follow-up, all QOL scores remained stable from baseline (means FACT-B: 118, FACT-G: 89, and TOI: 75). Improvements were observed among the subscales of the SF-36 from baseline to follow-up. The largest improvements were observed in physical and emotional role function scores, with 22% and 13% improvements from baseline to follow-up, respectively. Conclusions: A clinically implemented exercise intervention embedded in standard of care prevented decreases in QoL and improved physical and emotional functioning during the initial course of adjuvant breast cancer therapy. These findings support early implementation of lifestyle modification after a breast cancer diagnosis.
