e12082 Background: Nipple-sparing mastectomy (NSM) has gained popularity for surgical treatment of breast cancer. Terminal duct lobular units (TDLU) have been shown to be present in 25% of nipple areolar complex (NAC). Pathologic tumor subtype influence on presence of TDLU in the NAC has not been assessed. In addition, criteria for technically performing the dissection below the NAC have not been established. We sought to evaluate TDLU characteristics by tumor subtype and determine NSM dissection criteria below the NAC. Methods: A retrospective review was performed of 120 total and skin sparing mastectomies, 30 of each breast cancer subtype, from 1/2013 to 1/2015. The NAC of each mastectomy was assessed for number of TDLU and distance from TDLU to the skin. Results: Thirty of the 120 mastectomies (25%) had TDLU present below the NAC. Of the 30 with TDLU, there was no statistically significant difference in number of TDLU present based on tumor grade (gd) (gd 1 vs 2, p = .67; gd 1 vs 3, p = .24). Compared to luminal A, luminal B showed statistical significance (p < .05) for number of TDLU at the NAC whereas Her 2 and triple negative breast cancer (TNBC) were not statistically significant (p = .09 and .10). In mastectomies with TDLU present, gd 2 (p < .05) and gd 3 (p = .05) had a closer skin distance than gd 1. When compared by tumor subtype, there was no difference in TDLU to skin distance (table). Conclusions: NSM has been adopted as a safe oncologic approach to breast cancer treatment. Although presence of TDLU in luminal B subtype was statistically significant, this may not be clinically significant, as there were only 2 of 30 cases with TDLU. Our study indicates that a careful dissection at the level of the dermis below the NAC is necessary, as 25% of women will have TDLU present. This will provide an appropriate oncologic outcome similar to total and skin sparing mastectomy. Tumor subtype does not appear to be exclusion criteria for NSM. However, more aggressive dissection may be necessary to clear all TDLU from below the NAC in higher gd cancers. [Table: see text]

Breast conservation therapy has been the cornerstone of the surgical treatment of breast cancer for the last 20 years; however, recently, the use of mastectomy has been increasing. Mastectomy is one of the most frequently performed breast operations, and with novel surgical techniques, preservation of the skin envelope and/or the nipple-areolar complex is commonly performed. The goal of this paper is to review the literature on skin-sparing mastectomy and nipple-sparing mastectomy and to evaluate the oncologic safety of these techniques. In addition, this paper will discuss the oncologic importance of margin status and type of mastectomy as it pertains to risk of local recurrence and relative need for adjuvant therapy.

193 Background: Breast cancer resection strives for less radical approaches that offer superior aesthetic results without compromising oncologic safety. Nipple-sparing mastectomy (NSM) has gained popularity, but usually has been offered to smaller breasted and minimally ptotic women without history of extensive breast surgery. We present a series of nine nipple-sparing mastectomies following reduction mammoplasty. Methods: Charts of patients who underwent NSM following reduction mammoplasty at the NYU Medical Center from 2006 through 2011 were reviewed. Outcomes measured include post-operative complications, breast cancer recurrence, presence of cancer in the nipple-areolar complex, and nipple-areolar complex viability. Results: In total, the records of 235 (145 prophylactic, 90 therapeutic) NSM patients at NYU Medical Center were reviewed. Six patients for a total of 9 breasts had NSM following reduction mammoplasty. This subset of patients had a mean age of 46.2, mean BMI of 25.1, no history of diabetes and 1 smoker. Seven of 9 breasts were therapeutic resections and 2 of 9 were prophylactic. Time elapsed between reduction mammoplasty and NSM ranged from 33 days to 11 years. The majority of resections were in Stage 0 patients (6/9) with 1/9 in Stage I and 2/9 in Stage IIA. In all cases, prior reduction mammoplasty incisions were utilized for NSM. Eight patients were reconstructed immediately with tissue expanders, and 1 patient had a latissimus dorsi flap with immediate implant. Complications included 1 hematoma requiring evacuation and 1 displaced implant requiring revision. There were no positive subareolar biopsies and 100% nipple viability. Mean follow-up time was 9.4 months. Conclusions: Our experience demonstrates that NSM can be offered following reduction mammoplasty with comparable reconstructive outcomes to NSM alone. Reduction mammoplasty followed by NSM has potential as a reconstructive tool in prophylactic cases unsuited for primary NSM.

Abstract Seeking smaller and indistinct incisions, physicians have attempted endoscopic breast surgery in breast cancer patients. Unfortunately, there are some limitations in the range of movement and visualization of the operation field. Potentially addressing these limitations, we investigated the outcomes of gas and gasless robot-assisted nipple-sparing mastectomy (RANSM) with immediate breast reconstruction (IBR). Ten patients underwent 12 RANSM with IBR between November 2016 and April 2018. Patients with tumors measuring >5 cm in diameter, tumor invasion of the skin or nipple-areolar complex, proven metastatic lymph nodes, or planned radiotherapy were excluded. Age, breast weight, diagnosis, tumor size, hormone receptor status, and operation time were retrospectively collected. Postoperative outcomes including postoperative complications and final margin status of resected were analyzed. The median total operation time and console time were 351 min (267–480 min) and 51 min (18–143 min), respectively. The learning curve presented as a cumulative sum graph showed that the console time decreased and then stabilized at the eighth case. There was no open conversion or major postoperative complication. One patient had self-resolved partial nipple ischemia, and two patients experienced partial skin ischemia. We deemed that RANSM with IBR is safe and feasible for early breast cancer, benign disease of the breast, and BRCA 1/2 mutation carriers. RANSM is an advanced surgical method with a short learning curve.

AbstractAdvances in multi-modality treatments incorporating systemic chemotherapy, endocrine therapy, and radiotherapy for the management of breast cancer have resulted in a surgical-management paradigm change toward less-aggressive surgery that combines the use of breast-conserving or -reconstruction therapy as a new standard of care with a higher emphasis on cosmesis. The implementation of skin-sparing and nipple-sparing mastectomies (SSM, NSM) has been shown to be oncologically safe, and breast reconstructive surgery is being performed increasingly for patients with breast cancer. NSM and breast reconstruction can also be performed as prophylactic or risk-reduction surgery for women with BRCA gene mutations. Compared with conventional breast construction followed by total mastectomy (TM), NSM preserving the nipple–areolar complex (NAC) with breast reconstruction provides psychosocial and aesthetic benefits, thereby improving patients’ cosmetic appearance and body image. Implant-based breast reconstruction (IBBR) has been used worldwide following mastectomy as a safe and cost-effective method of breast reconstruction. We review the clinical evidence about immediate (one-stage) and delayed (two-stage) IBBR after NSM. Our results suggest that the postoperative complication rate may be higher after NSM followed by IBBR than after TM or SSM followed by IBBR.

74 Background: Brain metastatic breast cancer (BMBC) is often treated with whole brain radiation therapy (WBRT), stereotactic radiosurgery (SRS) or both. Breast cancer tumor subtypes defined by hormone receptor (HR) and HER2 status have an important prognostic role in metastatic disease. It is unclear if tumor subtypes have a prognostic role in patients receiving WBRT or SRS. We aimed to investigate the association between breast cancer subtype and overall survival (OS) among BMBC patients treated with WBRT and SRS. Methods: In a single-institution cohort study, BMBC patients treated with WBRT/SRS during 1997-2013 were identified. Clinico-pathological characteristics and survival information were prospectively collected. Tumor subtype category were defined as HR+/HER2-, HER2+/HR+, HER2+/HR- and triple negative (TN). WBRT category patients received that modality and SRS category patients, only SRS for treatment of brain metastases. OS is defined as time from diagnosis of brain metastasis to death or last follow-up. We conducted univariate analyses using the Kaplan-Meier method and log-rank tests and multivariate analysis using Cox proportional hazards models. Results: Among 193 BMBC patients who received WBRT or SRS, 62 received just SRS, and among them, 45% was HR+/HER2-. The distribution of subtypes was similar in WBRT patients. The median OS in SRS group was 15 months (95% CI 11-18) compared to WBRT with 10 months (95% CI 7-14) (p=0.03). Among patients receiving WBRT, median OS in HER2+/HR- tumor was 30 months (95% CI 13-37), HER2+/HR+ tumor - 14 months (95% CI 5-24), HER2-/HR+ tumor - 8 months (95% CI 4-11) and TN - 5 months (95% CI 3-9) (P=0.0003). There was no significant difference in OS between the breast cancer subtypes among SRS patients: median OS among patients with HER2+/HR- tumor was 11 months (95% CI 5–27), HER2+/HR+ tumor - 25 months (95% CI 7-32), HER2-/HR+ tumor - 18 months (95% CI 14-32), and TN - 12 months (95% CI 3-24) (p=0.07). Conclusions: Among patients with BMBC,tumor subtype is a prognostic factor for survival in those who received WBRT. Tumor subtype provided no prognostic information for those who were treated with only SRS.

166 Background: Nipple-sparing mastectomy (NSM) has been gathering increased recognition as an alternative to more traditional mastectomy approaches. However, the oncological safety of these procedures is still to be elucidated. The purpose of this study is to investigate technical feasibility of NSM without increasing the risk of local recurrence and complications. Methods: Ninety-eight stage 0-III breast cancer patients received NSM between January 2001 and April 2012 at Keio University Hospital. Eligible patients were without skin involvement and not indicated for breast-conserving therapy by preoperative imaging. The pathological analysis of the subareolar tissue was performed and nipple-areolar-complex (NAC) would be removed if positive. Four hundred seventy-four breast cancer patients who had mastectomy during the same period were used as a control group. Results: The median age was 46.0 years (range 29–68). The mean clinical tumor size was 2.8±1.2cm and the mean distance between the nipple and the tumor was 2.5±1.7cm. Ninety-one patients (92.9%) had clinically node-negative status. NAC involvement was observed in 3 patients (3.1%). Three patients (3.1%) presented with epidermal necrosis. After a median follow-up period of 37.3 months (range 1-136), there were 7 recurrences (7.1%), including 4 local recurrences (4.1%) and 3 distant metastases (3.1%). There was no statistically significant difference in local recurrence between the patients with NSM and mastectomy (4.1% vs. 3.2%; p=0.16). Immediate and delayed reconstruction was performed in 2 cases (2.0%) and 41 cases (41.8%), respectively. Conclusions: Our results suggested NSM may provide oncologic safety for strongly motivated and carefully selected patients.
