Cancer treatment-induced bone loss (CTIBL) is a common adverse effect among women with breast cancer receiving endocrine therapy, which negatively affects recovery and quality of life. Bone health management is important in this population. This study aimed to evaluate the feasibility and preliminary outcomes of the Rebuilding Osteo Strength with Exercise (ROSE) program for women with breast cancer.

A non-randomized controlled trial was conducted among 72 women with breast cancer receiving endocrine therapy. Participants self-selected into the intervention or control group, receiving either the ROSE program or enhanced health education. The 12-week, online-delivered ROSE program comprised health education, exercise interventions, and behavior change strategies. Feasibility was evaluated through recruitment, retention, and exercise adherence rates. Preliminary bone-health outcomes included changes in bone mineral density (BMD), physical fitness, osteoporosis-related symptoms, knowledge, self-efficacy, and quality of life.

Recruitment rate was 78.3%, with retention rates of 75% at 3 months and 50% at 6 months. High adherence to the exercise plan was observed: 92% for aerobic exercise, 91.7% for impact exercise, and 58% for resistance exercise. Small to moderate positive trends were found in physical fitness, osteoporosis-related symptoms, knowledge, and self-efficacy, though BMD and quality of life showed limited changes.

The ROSE program appears to be a feasible and safe approach for promoting bone health in breast cancer survivors. Future studies with longer follow-up and a larger sample are warranted to validate its long-term efficacy and mechanisms.
