Abstract

Background: Despite national guidelines recommending omission of sentinel lymph node biopsy (SLNB) and post-lumpectomy radiotherapy (RT) in older women with early-stage, hormone receptor-positive (HR+) breast cancer, these practices persist. This pilot study assesses whether a decision aid can target patient-level determinants of low-value treatments.

Methods: We adapted and pilot-tested a decision aid in women ≥70 years old with early-stage HR ​+ ​breast cancer. Primary outcomes included acceptability and appropriateness of the decision aid. Secondary outcomes included treatment choice and satisfaction with decision.

Results: Twenty-three patients enrolled in the trial. 19 completed survey one; 16 completed survey two. Primary outcomes demonstrated that 84% of patients agreed or strongly agreed the aid was acceptable and appropriate. Secondary outcomes demonstrated that 19% of patients underwent SLNB (below pre-intervention baseline), and 85% received adjuvant RT (change not statistically significant).

Conclusions: We demonstrate that a decision aid may effectively target patient-level factors contributing to overuse of low-value therapies.
