Objective: Areola-sparing mastectomy (ASM) is defined as resecting the nipple and any existing surgical biopsy scar, removing all breast parenchyma, and leaving a natural envelope of skin (including the areola), which improves the aesthetic result of immediate reconstruction. We previously demonstrated a <1% incidence of malignant involvement of the areola in a retrospective mastectomy series. Subsequently, we performed ASM on selected patients undergoing mastectomy. We report here our results from an ongoing study of ASM at our institution.
Methods: During a 20-month period, 17 ASMs with immediate reconstruction were performed on 12 patients. Patients were followed-up prospectively by the surgical oncologist for complications and recurrence.
Results: ASM was performed for breast cancer prophylaxis (n = 10), ductal carcinoma in situ (DCIS) (n = 4), and <2-cm peripheral infiltrating carcinoma (n = 3). The mean patient age was 47.7 years (range 37 to 61). Thirteen patients were reconstructed with tissue expanders and 4 with pedicle transverse rectus abdominus myocutaneous flaps. Ten patients underwent sentinel lymph node biopsy. None of the ten patients showed sentinel lymph node metastasis. Two patients with DCIS and microinvasion underwent subareolar touch-prep cytology, both of which were negative for malignancy. All mastectomy specimens had negative histologic margins. No patient received chemotherapy or radiation therapy. One postoperative consisted of a localized wound infection that resolved with oral antibiotics. At a median follow-up of 24 months (range 11 to 28), there were no instances of local or distant recurrence.
Conclusions: Overall, we found that ASM with immediate reconstruction provides excellent aesthetic results with infrequent complications. Furthermore, in this small series we showed no recurrence at 2 years. We continue to offer ASM for selected patients including those desiring surgical breast cancer prophylaxis as well as those with DCIS or small peripheral infiltrating ductal carcinoma.

Introduction: Breast cancer is the leading cause of neoplasm mortality among women. Several prevention strategies have been implemented to early detect and prevent the cancer occurrence. The most effective protocol includes prevention mastectomy for the high-risk patients.

Purpose: This aims to investigate the efficacy and safety of intercostal nerve anastomosis among breast cancer patients who undergo immediate subpectoral prosthetic breast reconstruction after nipple-areola-sparing mastectomy.
Methods: From 2022 to 2023, female patients between the ages of 20 and 60 diagnosed with stage I-IIIA breast cancer, who required and were willing to undergo immediate subpectoral prosthetic breast reconstruction after nipple-areola-sparing mastectomy, were screened and assigned to take the operation with (treatment group) or without (control group) intercostal nerve anastomosis (the nerves with appropriate length and thickness were selected from the 2nd-4th intercostal nerves, which were then dissociated and anastomosed to the posterior areola tissue). A radial incision at the surface projection of the tumor location was used.

Background: Nipple-sparing mastectomy (NSM) offers superior cosmetic outcomes and has been gaining wide acceptance. It has always been difficult to objectively quantify the risk of nipple-areola complex involvement (NACi). The goal was to develop a prediction model for clinical application.

Introduction: This study compares the perioperative results, aesthetic outcome and oncologic safety of single-port insufflation endoscopic nipple-sparing subcutaneous mastectomy combined with immediate reconstruction using prosthesis implantation (SIE-NSM-IRPI) with those of conventional open-nipple and areola-sparing subcutaneous mastectomy combined with immediate reconstruction using prosthesis implantation (C-NSM-IRPI).
Methods: In this retrospective cohort study, 64 early-stage breast cancer patients were divided into SIE-NSM-IRPI (n = 38) and C-NSM-IRPI (n = 26) groups. Perioperative results (operation time, intraoperative blood loss, incision length, drainage duration, and recent complications) were then compared between the two groups.

Background/aim: The prediction of a sub-areolar tissue infiltration in breast cancer (BC) patients could be helpful in selecting the best functional outcome according to several reconstructive oncoplastic or radical techniques. This study aims to evaluate the diagnostic performance of preoperative ultrasound (US) guided sub-areolar biopsy (SAB) in detecting occult nipple involvement, in comparison with the definitive pathological examination of tissue after surgery.
Patients And Methods: We prospectively recorded clinical and pathological data of 46 consecutive patients scheduled for breast conserving surgery or nipple-areola sparing mastectomy.
