Move Toward Recovery: A Feasibility Study for a Physical Activity Intervention to Reduce Post-Surgical Pain in Young Hispanic Breast Cancer Patients.

Young breast cancer survivors often develop post-breast surgery pain syndrome (PBSPS). Despite potential benefit from physical activity, access to in-person programs is often limited by competing work and caregiving responsibilities. We assessed the feasibility and acceptability of a remotely delivered physical activity intervention for young Hispanic breast cancer survivors with PBSPS. Our single-arm, 12-week feasibility study enrolled Hispanic women aged ≤60, at least 3 months post-treatment for invasive breast cancer or ductal carcinoma in situ (DCIS), with PBSPS. Using a Fitbit Inspire 3 activity tracker and health coaching, the program encouraged whole-of-day movement to increase activity. Feasibility outcomes included recruitment, retention, and adherence. Secondary outcomes assessed pain measures, daily steps, and quality of life (QOL). Twenty-five breast cancer survivors enrolled (mean age 47.4 years [SD 6.3]), with 76% selecting Spanish-language health coaching. Retention at 12 weeks was 79% (19/24). Engagement with health coaching was high, with 95% completing at least 4 of 5 pre-planned calls. The mean change in daily step count was 1502 (-348, 3353), with twelve (66.7%) increasing in step count (median 2334.5, range: 14, 13,422). Each additional 1000-step increase was associated with a 2.67-point increase in pain self-efficacy scores (β = 2.669, 95% CI: 0.884 to 4.454, p = 0.006). A remotely delivered, health coaching physical activity intervention was feasible and acceptable for young Hispanic breast cancer survivors with PBSPS. This supports further evaluation in a larger trial. Accessible survivorship interventions for young breast cancer patients in their preferred language are needed.
