Abstract
BACKGROUND: Many factors influence decisions regarding choice of breast-conserving surgery (BCS) versus mastectomy with reconstruction for early invasive breast cancer. The purpose of this study was to compare patient satisfaction following BCS and mastectomy with implant reconstruction (M-iR) utilizing the BREAST-Q patient-reported outcome measure. METHODS: Women with stage I or II breast cancer undergoing BCS or M-iR who completed a BREAST-Q from 2010 to 2016 were identified by retrospective review of a prospective database. Baseline characteristics were compared, and linear mixed models were used to analyze associations with BREAST-Q scores over time. RESULTS: Our study group was composed of 3233 women; 2026 (63%) had BCS, 123 (3.8%) had nipple-sparing mastectomy, and 1084 (34%) had skin-sparing or total mastectomy. Median time from surgery to BREAST-Q was 205 days for BCS and 639 days for M-iR (p < 0.001). Regardless of type of surgery, breast satisfaction scores decreased significantly over time (p < 0.001), whereas psychosocial (p = 0.001) and sexual (p = 0.004) well-being scores increased significantly over time. BCS was associated with significantly higher scores over time compared with M-iR across all subscales (all p < 0.001). Radiation was significantly associated with decreased scores over time across all subscales (all p < 0.05). CONCLUSIONS: Breast satisfaction and quality-of-life scores were higher for BCS compared with M-iR in early-stage invasive breast cancer. These findings may help in counseling women who have a choice for surgical treatment. Breast satisfaction scores decreased over time in all women, highlighting the need for further evaluation with longer follow-up.
