The main goal of oncoplastic breast surgery (OBS) is to optimize cosmetic outcomes and reduce patient morbidity, while still providing an oncologically-safe surgical outcome and extending the target population of conservative surgery. Although the growing number of reported experiences with oncoplastic surgery, few studies account for the long-term outcomes. Between January 2000 and December 2010, 1024 consecutive oncoplastic surgeries were performed and prospectively included in a database. Demographic data, histological and oncological evaluation and surgical complications were recorded. The role of tumor and patients' characteristics on the development of local recurrence and metastases were assessed by multivariate analysis. Median follow up was 74.2 months. The average age of patients was 56.24. In 869 patients (84.9%) an invasive tumor and in 155 (15.1%) an in situ tumor (11% DCIS and 4% LIN) was found. The average size of the tumor was 24.5 mm. A positive margin presented in 67 (6.5%) patients. Forty patients (50%) underwent re-excision and 39 (49.4%) underwent mastectomy. The overall breast conservation rate was 96.2%. Reported complications were: 17 wound infections (1.7%); 106 hematomas (10.4%); 94 lymphorrheas (9.2%), 48 partial wound dehiscence (4.7%). Local recurrences (LR) were observed in 49 patients (4.7%). The risk of local recurrence was significantly higher in the group of patients with lymphovascular invasion and with high grade (G) (p < 0.05). 52 (5.07%) distant metastases were reported and the related risk was significantly higher in the group of patients with lymphovascular invasion and with negative receptors (p < 0.05). Oncoplastic surgery provides an acceptable oncological long-term outcome and can be used to treat with conservative surgery also a selected population of patients who would had otherwise undergone mastectomy in the past.
