Outcomes for breast cancer survivors with metastatic disease in a physical activity program for medically underserved cancer survivors

Purpose This study examined the effectiveness and feasibility of the Active Living After Cancer (ALAC) program for metastatic breast cancer (MBC) survivors. Methods ALAC is a 12-session community-based program to help cancer survivors improve their physical functioning and quality of life through increased physical activity. ALAC participants with MBC (stage IV) were compared to survivors with early-stage breast cancer (stages I and II). The International Physical Activity Questionnaire, Godin Leisure-Time Physical Activity, 30-second sit-to-stand test, and PROMIS Global Health were administered at baseline and follow-up. Program satisfaction and retention were assessed at week 12. Repeated-measures mixed models were used to compare changes in outcomes between survivors with early-stage breast cancer and MBC. Results A total of 585 women (59.3 y +/- 10.6), most of whom were Hispanic (54%) or non-Hispanic Black (22%), were included (early stage, n = 538; MBC, n = 47). After the ALAC program, a significant increase in physical activity (P < 0.001), improved physical and mental health T-scores (P < 0.001), and more sit-to-stand repetitions (P < 0.001) were observed for both survivors with early-stage breast cancer and MBC. Women with MBC showed significantly lower physical health (P = 0.037) and physical function (P = 0.010) compared to early-stage at baseline. Conclusions The ALAC program increased physical activity and improved health-related quality of life and physical function among breast cancer survivors with both early-stage and metastatic disease. Implications for Cancer Survivors This study emphasizes the importance of incorporating physical activity interventions like the ALAC program into the comprehensive care of cancer survivors, including those with metastatic disease.
