Psychological effects of mastectomy for women with breast cancer have driven treatments that optimize cosmesis while strictly adhering to oncologic principles. Although skin-sparing mastectomy is oncologically safe, questions remain regarding the use of nipple–areola complex (NAC)-sparing mastectomy (NSM). We prospectively evaluated NSM for patients undergoing mastectomy for early-stage breast cancer or risk reduction.
We enrolled 33 early-stage breast cancer and high-risk patient; 54 NSMs were performed. NAC viability and surgical complications were evaluated. Intraoperative and postoperative pathologic assessments of the NAC base tissue were performed. NAC sensory, cosmetic and quality of life (QOL) outcomes were also assessed.
Twenty-one bilateral and 12 unilateral NSMs were performed in 33 patients, 37 (68.5%) for prophylaxis and 17 (31.5%) for malignancy. Mean age was 45.4 years. Complications occurred in 16 NACs (29.6%) and 6 skin flaps (11.1%). Operative intervention for necrosis resulted in 4 NAC removals (7.4%). Two (11.8%) of the 17 breasts with cancer had ductal carcinoma-in-situ at the NAC margin, necessitating removal at mastectomy. All evaluable patients had nipple erection at 6 and 12 months postoperatively. Cosmetic outcome, evaluated by two plastic surgeons, was acceptable in 73.0% of breasts and 55.8% of NACs, but lateral displacement occurred in most cases. QOL assessment indicated patient satisfaction.
NSM is technically feasible in select patients, with a low risk for NAC removal resulting from necrosis or intraoperative detection of cancer, and preserves sensation and QOL. Thorough pathologic assessment of the NAC base is critical to ensure disease eradication.
