Abstract

Background: To identify risk factors of recurrence in a large series of patients with breast cancer who underwent a nipple-sparing mastectomy (NSM). Patients and methods: Breast-related recurrences and local recurrences (LR) in the breast and the nipple areola complex (NAC) were studied. Cumulative incidences of events were estimated through competing risk analysis. Multivariate Cox regression models were also applied. Results: We identified 934 consecutive NSM patients during 2002-2007. Median follow-up was 50 months. In 772 invasive carcinoma patients, the rate of LR in the breast and in the NAC was 3.6% and 0.8%, respectively. In the 162 patients with intraepithelial neoplasia, the rate of LR in the breast and in the NAC was 4.9% and 2.9%, respectively. The significant risk factors of LR in the breast for the group A were grade, overexpression/amplification of HER2/neu and breast cancer molecular subtype Luminal B. In group B, the risk factors of LR in the breast and in the NAC were age (
