ASO Visual Abstract: Timing of Chemotherapy and Patient-Reported Outcomes After Breast-Conserving Surgery and Mastectomy with Immediate Reconstruction
Annals of surgical oncology(2023)
摘要
Introduction Receipt of chemotherapy is associated with decreased satisfaction after breast surgery, but whether timing as adjuvant versus neoadjuvant (NAC) affects patient-reported outcomes (PROs) is unclear. We examined associations between chemotherapy timing and PROs after breast-conserving surgery (BCS) and mastectomy with immediate reconstruction (M-IR). Methods In this retrospective cohort study of patients with stage I-III breast cancer undergoing chemotherapy between January 2017 and December 2019, we compared satisfaction with breasts (SABTR) and chest physical well-being (PWB-CHEST) between chemotherapy groups in BCS and M-IR cohorts. Median SABTR and PWB-CHEST scores (scale 0–100) were compared between chemotherapy groups at baseline and for 3 years postoperatively. Factors associated with SABTR and PWB-CHEST at 1 and 2 years were assessed with multivariable linear regression. Results Overall, 640 patients had BCS and 602 had M-IR; 210 (33%) BCS patients and 294 (49%) M-IR patients had NAC. Following BCS, SABTR was higher than baseline at all postoperative timepoints, whereas 3-year SABTR remained similar to baseline following M-IR, independent of chemotherapy timing. In both surgical cohorts, PWB-CHEST was lowest after NAC at 6 months compared with baseline but was similar to adjuvant counterparts by 3 years. NAC was not a statistically significant predictor of SABTR or PWB-CHEST in either surgical cohort on multivariable analysis. Conclusions For patients with breast cancer who require chemotherapy, neoadjuvant versus adjuvant timing does not impact long-term PROs in this study. These findings may inform shared decision making regarding the sequence of treatment in patients with operable disease.
