Abstract

Nipple‑sparing mastectomies (NSMs) are increasingly used in the surgical treatment of patients with breast cancer and for prevention of breast cancer. The present study was performed to review the outcomes of patients undergoing NSMs at a single large university setting. A retrospective chart review was performed on all patients undergoing NSMs from 2008‑2014. Charts were reviewed for demographic data and patient characteristics. Tumor and breast size, cancer recurrence and complications were also evaluated. Descriptive statistics were utilized to summarize the findings. From 2008‑2014, 110 patients underwent 197 NSMs. The mean patient age was 44.4 years (range, 20‑77). The average body mass index was 24 (range, 18‑47). Breast weight was available for 106 specimens, with a mean weight of 475.5 g (range, 124.1‑1,625.0 g). Seventy‑three NSMs were performed for cancer and 124 were performed prophylactically. The mean tumor width was 1.38 cm (range, 0‑6.0 cm), with an average nipple to tumor distance of 5.87 cm (range, 2.93‑10.0 cm). Three (4%) patients required removal of the nipple areolar complex (NAC) due to pathological extension of the tumor. A total of 34 (17.2%) complications occurred, including infections, hematomas and nipple necrosis, with 9 requiring removal of the NAC and 13 requiring removal of the tissue expander or implant. Smokers had a 36.0% (9/25) complication rate, compared with 14.5% (25/172) of nonsmokers (P<0.05). During follow‑up, one recurrence was noted, located on the chest wall. There were no recurrences in the NAC group. Therefore, NSMs may safely be performed without compromising oncologic outcomes or increasing complication rates in properly selected patients.
