Purpose Although breast-conserving surgery is a standard approach for patients with breast cancer, mastectomy often becomes necessary. Surgical options now include nipple-sparing mastectomy but its oncological safety is still controversial. This study evaluates frequency and patterns of occult nipple involvement in a large contemporary cohort of patients with the retroareolar margin as possible indicator of nipple involvement. Patients and Methods Three hundred sixteen consecutive mastectomy specimens (232 therapeutic, 84 prophylactic) with grossly unremarkable nipples were evaluated by coronal sections through the entire nipple and subareolar tissue. Extent and location of nipple involvement by carcinoma was assessed with the tissue deep to the skin as potential retroareolar en-face resection margin. Results Seventy-one percent of nipples from therapeutic mastectomies showed no pathologic abnormality, 21% had ductal carcinoma in situ (DCIS), invasive carcinoma (IC), or lymphovascular invasion (LVI), and 8% lobular neoplasia (lobular carcinoma in situ). Human epidermal growth factor receptor 2 amplification, tumor size, and tumor-nipple distance were associated with nipple involvement by multivariate analysis (P = .0047, .0126, and .0176); histologic grade of both DCIS (P = .002) and IC (P = .03), LVI (P = .03), and lymph node involvement (P = .02) by univariate analysis. Nipple involvement by IC or DCIS was identified in the retroareolar margin with a sensitivity of 0.8 and a negative predictive value of 0.96. None of the 84 prophylactic mastectomies showed nipple involvement by IC or DCIS. Conclusion Nipple-sparing mastectomy may be suitable for selected cases of breast carcinoma with low probability of nipple involvement by carcinoma and prophylactic procedures. A retroareolar en-face margin may be used to test for occult involvement in patients undergoing nipple-sparing mastectomy.

Objective: Women with mutations in breast cancer predisposition genes have a significantly higher lifetime risk of developing breast cancer and can opt for risk-reducing mastectomy. Women with positive family history of cancer can also opt for prophylactic surgery as a preventive method in selected cases. Current studies showed reduced risk of developing breast cancer after prophylactic nipple-sparing mastectomy; however, despite the good clinical outcomes, one of the main concerns regarding nipple-sparing mastectomy (NSM) is the oncologic safety and nipple-areola complex preservation. In this study, we aimed to evaluate the indications, complication rates and unfavorable events of 62 Brazilian patients who underwent 124 risk-reducing NSM from 2004 to 2018. Methods: Patient data was reviewed retrospectively and descriptive statistics were utilized to summarize the findings. Results: The mean patients’ age was 43.8 years. The main indication for risk-reducing NSM was the presence of pathogenic mutation (53.3%), followed by atypia or lobular carcinoma in situ (25.8), and family history of breast cancer and/or ovarian cancer (20.9%). There were four (3.2%) incidental diagnosis of ductal carcinoma in situ and one invasive ductal carcinoma (0.8%). From the 124 prophylactic NSM performed, two (1.6%) complications occurred: one (0.8%) infection and one (0.8%) partial nipple necrosis. In a mean follow-up of 50 months, there was one (1.6%) newly diagnosed breast cancer in the 62 patients undergoing prophylactic NSM. Conclusions Our findings demonstrated efficacy and safety to perform NSM as prophylactic surgery with good oncologic outcomes and low complication rates in a case series of Brazilian patients.

177 Background: Pleomorphic lobular carcinoma in situ (PLCIS) is an increasingly diagnosed variant of lobular carcinoma in situ. Histologically, it resembles ductal carcinoma in situ (DCIS), leading to controversy over proper management. Yet, the natural history of PLCIS is unknown. Here we describe our experience with PLCIS. Methods: Review of pathology reports (1995–2012) identified 233 cases of LCIS variants. Patients with synchronous ipsilateral DCIS or invasive cancer (IC) were excluded leaving 25 cases for review. Consensus review by 3 pathologists further excluded 7; leaving 18 cases, 12 of which were classified as PLCIS and 6 as LCIS with pleomorphic features (LCIS-PF). (Table) PLCIS was defined by cellular dyshesion, nuclear pleomorphism with a 2-3 fold size variation, conspicuous nucleoli, mitoses and abundant cytoplasm; lesions not meeting all parameters were classified as LCIS-PF. Loss of e-cadherin was confirmed; clinical data were obtained from medical records. Results: Mean patient age at diagnosis of PLCIS/LCIS-PF was 57 yrs (42-67 yrs). All cases presented with imaging abnormalities. A previous history of breast cancer was present in 7/18 (39%) pts (3/7, ipsilateral; 4/7, contralateral). Following PLCIS/LCIS-PF diagnosis, 6/18 (33%) pts underwent mastectomy and 12/18 had excision alone, with (n=3) or without chemoprevention (n=9). Margin status was negative in 4/12 pts; close in 3/12 pts and positive in 5/12 pts undergoing excision. At a median follow-up of 27 mos (2-148 mos), 2/12 pts treated with excision developed ipsilateral breast cancer (1 DCIS; 1 IC). Both had close margins at initial excision; median time to cancer, 54 mos. Conclusions: Pure PLCIS is an uncommon lesion. Synchronous malignancy or prior history of breast cancer are often present in patients with PLCIS, contributing to the difficulty in determining the actual risk conferred by this lesion and appropriate management. Efforts to systematically characterize LCIS variants and prospective documentation of outcomes are needed to clarify the significance of these lesions. [Table: see text]

The following article represents a clinical case study of a synchronous breast cancer in a 47 year old woman with no prior significant comorbidities.Up to 10% of all breast cancers can be synchronous (usually found with the help of breast MRI). The occurrence of bilaterally is considerable with invasive lobular carcinoma. The patient observed after self-palpating her breast a nodule in the infero-external quadrant of the right breast. During almost 4 months the patient underwent punch biopsy of the right breast, lumpectomy and finally double mastectomy with immediate reconstruction using Mentor implants and AMD. The histopathological result showed ductal carcinoma in situ in the right breast and lobular carcinoma in situ in both breasts. Postoperatively the patient is free of cancer, but under clinical and imagistic surveillance.

Purpose The increased breast cancer risk conferred by a diagnosis of lobular carcinoma in situ (LCIS) is poorly understood. Here, we review our 29-year longitudinal experience with LCIS to evaluate factors associated with breast cancer risk. Patients and Methods Patients participating in surveillance after an LCIS diagnosis are observed in a prospectively maintained database. Comparisons were made among women choosing surveillance, with or without chemoprevention, and those undergoing bilateral prophylactic mastectomies between 1980 and 2009. Results One thousand sixty patients with LCIS without concurrent breast cancer were identified. Median age at LCIS diagnosis was 50 years (range, 27 to 83 years). Fifty-six patients (5%) underwent bilateral prophylactic mastectomy; 1,004 chose surveillance with (n = 173) or without (n = 831) chemoprevention. At a median follow-up of 81 months (range, 6 to 368 months), 150 patients developed 168 breast cancers (63% ipsilateral, 25% contralateral, 12% bilateral), with no dominant histology (ductal carcinoma in situ, 35%; infiltrating ductal carcinoma, 29%; infiltrating lobular carcinoma, 27%; other, 9%). Breast cancer incidence was significantly reduced in women taking chemoprevention (10-year cumulative risk: 7% with chemoprevention; 21% with no chemoprevention; P < .001). In multivariable analysis, chemoprevention was the only clinical factor associated with breast cancer risk (hazard ratio, 0.27; 95% CI, 0.15 to 0.50). In a subgroup nested case-control analysis, volume of disease, which was defined as the ratio of slides with LCIS to total number of slides reviewed, was also associated with breast cancer development (P = .008). Conclusion We observed a 2% annual incidence of breast cancer among women with LCIS. Common clinical factors used for risk prediction, including age and family history, were not associated with breast cancer risk. The lower breast cancer incidence in women opting for chemoprevention highlights the potential for risk reduction in this population.
