Oncologic Outcomes of Breast Cancer Patients Treated with Oncoplastic Surgery

Background: The impact of breast appearance after breast cancer surgical treatment on patients ’ quality of life led to the development of the oncoplastic approach. However, studies reporting oncologic results associated with this treat-ment strategy are scarce. This cross-sectional study was designed to assess oncologic outcomes among patients who underwent oncoplastic surgery. Methods: A total of 190 breast cancer patients who underwent breast-conserving sur-gery were enrolled. Fifty of them underwent oncoplastic surgery and 140 had none breast reconstruction procedure (control group). All surgeries were performed by the same surgical team. Results: Groups were similar with regard to staging, histological type, grade of the tumor, presence of intraductal component, hormone receptors and nodal com-mitment. Patients in oncoplastic surgery group had larger tumors (ρ = 0.001) and more lymphovascular invasion (ρ = 0.047). Further, a higher proportion of them underwent chemotherapy (ρ = 0.030). Follow-up time of control group was longer (ρ = 0.05), and these patients also had a longer relapse-free survival time (ρ = 0.001). Local recurrence rate was 5.8 % (11/190) and it was significantly greater in the oncoplastic surgery group (8/11, ρ = 0.001). Time to local recur-rence after surgery was longer in oncoplastic surgery group (ρ = 0.002). Overall, patients in oncoplastic surgery grou
