Background: Oncoplastic breast conserving surgery (OBCS) integrates plastic surgery techniques in the resection of breast cancer and lowers the rate of re-excision while improving breast cosmesis. The goal of this study is to compare the surgical site complication rate of OBCS with that of standard BCS. Methods: A single institution chart review evaluated all patients undergoing BCS for treatment of breast cancer. Patients treated from January 2009 to December 2010, prior to adoption of oncoplastic techniques, were identified as the standard surgery (SS) group. Patients treated with OBCS from January 2013 to July 2015 were identified as the oncoplastic surgery (OS) group. All surgical site complications were recorded. Results: Overall, 561 patients were evaluated. The SS group comprised 273 patients compared with 288 patients in the OS group. Surgical site complications occurred in 49 patients (17.9%) in the SS group compared with 23 patients (8.0%) in the OS group (p < 0.001). Discussion: Overall, BCS has a low rate of significant surgical site complications. OBCS has a lower rate of surgical site complications compared to standard BCS.
