Abstract
BACKGROUND: Breast-conserving therapy (BCT) has been associated with better quality of life and cosmetic outcomes than mastectomy. However, subareolar cancers abutting the nipple-areolar complex (NAC) present a unique cosmetic and oncologic challenge. Oncoplastic central partial mastectomy and neoareolar reduction mammoplasty with immediate nipple reconstruction is a novel technique that can permit BCT for these patients. METHODS: This study enrolled consecutive patients with central tumors during 2017-2018 who underwent central partial mastectomy reconstructed with neoareolar reduction mammoplasty and immediate nipple reconstruction. Patient demographics, imaging and pathology size, margin width, mastectomy and reexcision rates, and cosmesis were evaluated. RESULTS: The study identified 23 sequential patients. The average patient age was 60.5 ± 12.3 years, and the average body mass index was 29.4 ± 5.7 kg/m2. The mean lesion size was 51.5 ± 43.0 mm on preoperative imaging, and the average disease span shown by the final pathology was 59.5 ± 45.3 mm. "No ink on tumor" was achieved for 22 patients (95.7%). In 13 patients (56.5%), the margins were inadequate for ductal carcinoma in situ (DCIS) (n = 12) or invasive cancer (n = 1). Good to excellent cosmetic results were achieved for 21 patients (95.5%). Complications occurred for six patients (26.1%), including three patients with ischemia of the reconstructed NAC. CONCLUSION: The single-stage operation described in this report can allow patients with cancers abutting the NAC to consider BCT. This technique allows patients to avoid mastectomy and to minimize the number of operations required for reconstruction while maximizing cosmetic outcomes. In the study cohort, the presence of extensive DCIS resulted in a significant need for reexcision, which could be performed successfully without compromise to cosmetic outcome.
