Safety of Atypical Ductal Hyperplasia at the Nipple Margin in Nipple-Sparing Mastectomy.

ABSTRACT:

Purpose

Controversies persist regarding contraindications for nipple-sparing mastectomy (NSM). This study aimed to assess the accuracy of subareolar frozen section analysis and identify risk factors for nipple-areola complex (NAC) recurrence post NSM.

Methods

Consecutive cases of primary invasive breast cancer undergoing NSM at our single center from January 2015 to December 2020 were retrospectively reviewed.

Results

The nipples were retained in 126 patients (127 breasts), and the areola was retained with nipple excision for five breasts. Frozen section analysis demonstrated a sensitivity of 81.8% and specificity of 95.3%. The NAC recurrence rate was 4.3% over a median follow-up period of 48 (30-105) months. An atypical ductal hyperplasia (ADH) at the margin emerged
