A Clinical Analysis of Prognosis and Patient-Reported Outcomes of Oncoplastic Breast-Conserving Surgery for Early Breast Cancer: A Retrospective Cohort Study.

Purpose: Approximately 25-30% of patients suffer from breast deformity and/or asymmetry after conventional breast-conserving surgery (CBCS). Generally, it is thought that oncoplastic breast-conserving surgery (OBCS) results in an improved cosmetic result; however, studies comparing the prognosis and aesthetic outcomes of CBCS and OBCS in early breast cancer (EBC) are inadequate.

Methods: A total of 143 patients were included in this retrospective cohort study; 53 underwent OBCS and 90 underwent CBCS.
