What does this research mean for the field?

Breast cancer survivors on adjuvant endocrine therapy who decline remote exercise trials report higher baseline physical activity than acceptors, with the most common reasons for declining being existing physical activity routines and lack of time for in-person assessments. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To identify reasons for non-participation and evaluate clinical and physical profiles of breast cancer survivors on adjuvant endocrine therapy who declined a remote exercise trial.

Overview

Randomized trial uncovers higher preexisting activity among non-participants in breast cancer survivors, suggesting perceived self-sufficiency and in-person testing logistics hinder trial enrollment.

Key Points

To identify reasons for non-participation and evaluate clinical and physical profiles of breast cancer survivors on adjuvant endocrine therapy who declined a remote exercise trial.
Nested within a randomized trial (ReBEC RBR-3tqb39m), 73 screened breast cancer survivors on adjuvant endocrine therapy were evaluated, of whom 39 enrolled and 30 declined.
Surveyed 21 decliners regarding non-participation reasons, physical activity (IPAQ), fatigue (FACT-F), and quality of life (FACT-B), comparing metrics to baseline acceptors (N=39).
Decliners reported significantly greater baseline physical activity than acceptors (IPAQ: 3,108 [1,840–5,139] vs. 2,046 [960–4,216] MET-min/week; p = 0.04).
Fatigue showed a non-significant trend toward better scores among decliners (FACT-F: 134 vs. 118; p = 0.06), while quality of life did not differ (FACT-B: 113 vs. 110; p = 0.332).
The predominant reasons for declining participation were preexisting physical activity (52%) and lack of time for required in-person baseline assessments (48%).
