Abstract

Purpose: Older women with nonmetastatic breast cancer can often choose from several surgery and radiation treatment options. Little is known regarding how these choices contribute to decisional regret, which is a negative emotion reflecting the idea that another surgery or radiation decision might have been preferable. We sought to characterize the burden of and examine potential risk factors for local therapy decisional regret among a population-based cohort of older breast cancer survivors. Methods and Materials: National Medicare claims for age ≥67 female breast cancer incident in 2009 identified patients treated with lumpectomy plus whole-breast irradiation, brachytherapy, or endocrine therapy or mastectomy with or without radiation. We sampled 330 patients per treatment group (N = 1650), of whom 1253 agreed to receive a paper survey including the Decisional Regret Scale and EQ-5D-3L Health-Utility Scale. Local therapy regret was defined as neutral or worse response to questions regarding surgery- or radiation-related decisional regret. Local therapy regret risk factors were evaluated using a multivariable generalized linear model. Association of local therapy regret with health utility was modeled using multivariable linear regression. Results: The response rate was 30.2% (n = 498 of 1650); 421 surveys were included in this analysis. Median diagnosis age was 72 years, and surveys were completed 6 years after diagnosis. Overall, 23.8% of respondents (n = 100)reported experiencing local therapy decisional regret. Type of local therapy was not associated with local therapy regret. Predictors of increased regret included black race (risk ratio [RR], 2.09; 95% confidence interval [CI], 1.33-3.29), high school education or less (RR, 1.87; 95% CI, 1.27-2.75), and axillary nodal dissection (RR, 2.13; 95% CI, 1.33-3.41). Local therapy regret was not associated with health utility (P =.37). Conclusions: Local therapy regret afflicts nearly one quarter of our cohort of older breast cancer survivors, and it is associated with black race, less education, and more extensive nodal dissection, but not breast surgery. Regret is distinct from health utility, suggesting that it is a unique psychosocial construct that merits further study and mitigation strategies.
