Golijanin D, Radovanović Z, Radovanović D, Đermanović A, Starčević S, Đermanović M. Molecular subtype and risk of local recurrence after nipple‑sparing mastectomy for breast cancer. Oncol Lett 2024; 28:389. [PMID: 38966584 PMCID: PMC11223028 DOI: 10.3892/ol.2024.14522] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Accepted: 06/03/2024] [Indexed: 07/06/2024] Open
Abstract
The present study aimed to investigate whether local recurrence (LR) after nipple-sparing mastectomy (NSM) and reconstruction was associated with i) Ki67 values and molecular subtypes of the initial lesions, and ii) the size of the initial tumor and the size of the implant. A total of 156 patients with breast cancer with a mean age of 51.58 years (age range, 26-75 years) who underwent NSM with primary implant breast reconstruction were analyzed. After surgery, the mean follow-up time was 59.26 months (range, 17-85 months). Molecular subtypes, Ki67 values, estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) status were recorded for each patient. Additionally, information regarding the size of the implant and the initial tumor size were collected. The information was used to assess LR. For univariate analyses of risk factors, χ2 test, Fisher's exact test, Mann-Whitney U test and Student's t-test for independent samples were used. For multivariate analyses, a Cox proportional-hazards model was used. NSM was the primary treatment for breast cancer in 34/156 patients (21.8%), while 122/156 (78.2%) of patients received neoadjuvant chemotherapy followed by surgery. Luminal B was the most frequent molecular subtype, detected in 82/156 patients (52.6%), whereas the luminal A subtype was detected in 37 patients (23.7%) and the HER2-enriched subtype was detected in 17/156 patients (10.9%). Ki67 expression was low in 13/156 patients (8.3%), while medium expression was detected in 78/156 patients (50.0%) and high expression was present in 58/156 patients (37.2%). LR was noted in 17/156 patients (10.9%). As determined by univariate analysis, lower ER (P=0.010) and PR (P=0.008) expression were indicated to be significant risk factors for LR. In conclusion, in the present patient cohort, low ER and PR expression were risk factors for LR of breast cancer, whereas Ki67 status and molecular subtype were not statistically significant risk factors for LR. Additionally, the size of the initial tumor and the size of the implant were not risk factors for LR. These findings are consistent with the current literature, and should be utilized when discussing treatment options and potential clinical outcomes with patients prior to surgical management.

Abstract
PURPOSE Controversies persist regarding contraindications for nipple-sparing mastectomy (NSM). This study aimed to assess the accuracy of subareolar frozen section analysis and identify risk factors for nipple-areola complex (NAC) recurrence post NSM. METHODS Consecutive cases of primary invasive breast cancer undergoing NSM at our single center from January 2015 to December 2020 were retrospectively reviewed. RESULTS The nipples were retained in 126 patients (127 breasts), and the areola was retained with nipple excision for five breasts. Frozen section analysis demonstrated a sensitivity of 81.8% and specificity of 95.3%. The NAC recurrence rate was 4.3% over a median follow-up period of 48 (30-105) months. An atypical ductal hyperplasia (ADH) at the margin emerged as an independent factor for NAC recurrence in multivariate Cox regression analysis (hazard ratio, 25.464; 95% confidence interval, 1.841-352.145; p = 0.016). Kaplan-Meier survival analysis revealed no statistically significant reduction in overall survival rates (log-rank test, p = 0.660). CONCLUSION Frozen sections of subareolar tissue are reliable and re-excision may be necessary when ADH is detected at the nipple margin in NSM. The NAC recurrence rate was low, and the outcome was favorable following wide local excision.

Abstract
BACKGROUND Intraoperative examination of retro-areolar margin (IERM) often is used during nipple-sparing mastectomy (NSM) for cancer, but there is no robust data regarding its real advantage. METHODS Consecutive patients undergoing NSM for cancer with omission of IERM according to institutional protocols from 2016 to 2021 were retrospectively analyzed. The decision to maintain or remove the Nipple-Areola Complex (NAC) after definitive pathology was taken at the multidisciplinary meeting. RESULTS Among 162 women operated in the study period, the presence of neoplastic cells within 2 mm from the inked retroareolar margin (RAM) was detected at permanent pathology in 17 cases (10.5%). Nipple-Areola-Complex (NAC) was removed postoperatively in five patients (3%) for margins <1 mm, the other 12 were observed, whereas postoperative NAC necrosis required surgical removal in additional five cases (3%). The NAC was thus preserved in 152 of 162 patients (94%). At multivariate analysis, RAM ≤2 mm was associated with radiological tumor-to-nipple distance less than or equal to 1 cm (p = 0.04) and Ki67 label index ≥ 20 (p = 0.04), whereas multifocality/multicentricity showed a trend towards significance (p = 0.07). At a median follow-up of 46 months, five locoregional relapses occurred (3%), only one of them involving the NAC (0, 6%). Locoregional relapse and overall survival for patients with RAM > or < 2 mm were not different. CONCLUSIONS IERM is not routinely necessary during NSM for cancer, because its omission is associated with a very low return to the operating room, it is oncologically safe, and associated pitfalls are avoided. Further studies are necessary to confirm these findings.

Diagnostic Accuracy of Magnetic Resonance Imaging Features and Tumor-to-Nipple Distance for the Nipple-Areolar Complex Involvement of Breast Cancer: A Systematic Review and Meta-Analysis. Korean J Radiol 2023; 24:739-751. [PMID: 37500575 PMCID: PMC10400374 DOI: 10.3348/kjr.2022.0846] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 05/02/2023] [Accepted: 05/19/2023] [Indexed: 07/29/2023] Open
Abstract
OBJECTIVE This systematic review and meta-analysis evaluated the accuracy of preoperative breast magnetic resonance imaging (MRI) features and tumor-to-nipple distance (TND) for diagnosing occult nipple-areolar complex (NAC) involvement in breast cancer. MATERIALS AND METHODS The MEDLINE, Embase, and Cochrane databases were searched for articles published until March 20, 2022, excluding studies of patients with clinically evident NAC involvement or those treated with neoadjuvant chemotherapy. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Two reviewers independently evaluated studies that reported the diagnostic performance of MRI imaging features such as continuity to the NAC, unilateral NAC enhancement, non-mass enhancement (NME) type, mass size (> 20 mm), and TND. Summary estimates of the sensitivity and specificity curves and the summary receiver operating characteristic (SROC) curve of the MRI features for NAC involvement were calculated using random-effects models. We also calculated the TND cutoffs required to achieve predetermined specificity values. RESULTS Fifteen studies (n = 4002 breast lesions) were analyzed. The pooled sensitivity and specificity (with 95% confidence intervals) for NAC involvement diagnosis were 71% (58-81) and 94% (91-96), respectively, for continuity to the NAC; 58% (45-70) and 97% (95-99), respectively, for unilateral NAC enhancement; 55% (46-64) and 83% (75-88), respectively, for NME type; and 88% (68-96) and 58% (40-75), respectively, for mass size (> 20 mm). TND had an area under the SROC curve of 0.799 for NAC involvement. A TND of 11.5 mm achieved a predetermined specificity of 85% with a sensitivity of 64%, and a TND of 12.3 mm yielded a predetermined specificity of 83% with a sensitivity of 65%. CONCLUSION Continuity to the NAC and unilateral NAC enhancement may help predict occult NAC involvement in breast cancer. To achieve the desired diagnostic performance with TND, a suitable cutoff value should be considered.

Abstract
INTRODUCTION The use of nipple-sparing mastectomy (NSM) combined with breast reconstruction is increasing in breast cancer surgeries despite its controversial safety profile. To reduce the recurrence rate of tumors in the nipple-areola complex (NAC), we used intraoperative radiotherapy (IORT). The purpose of this study was to explore patients' feedback on this novel treatment strategy. PATIENTS AND METHODS From January 2014 to May 2018, eligible patients with breast cancer were enrolled in this study and separated into 2 groups. Patients in the NSM group underwent IORT to the NAC flap, and patients in the skin-sparing mastectomy (SSM) group underwent SSM and breast reconstruction. The postoperative satisfaction was collected and assessed using the Breast-Q reconstruction questionnaire and a standardized questionnaire; this was compared between the 2 groups. RESULTS There were 46 patients (52 NSMs) in the NSM group and 20 patients (22 SSMs) in the SSM group. The breast-Q scores were higher in the NSM group than the SSM group, with trends for a 'higher satisfaction with breasts' (67.39 ± 20.59 vs. 55.00 ± 19.33; p = 0.026) and 'higher sexual well-being' (61.74 ± 22.24 vs. 49.50 ± 20.12; p = 0.039). All the patients recognized the importance of nipple preservation. Thirty-seven women (80.40%) were satisfied or very satisfied with the appearance and shape of the NAC in the NSM group, while 38/46 women (82.60%) were very unsatisfied or unsatisfied with the sensitivity of the nipples. CONCLUSIONS The Breast-Q scores showed great satisfaction with breasts and sexual well-being in the NSM group. However, more effort should be made in improving postoperative NAC sensitivity.

Abstract
BACKGROUND Nipple-sparing mastectomy (NSM) is increasingly used for women with breast cancer who are not candidates for conservative surgery. The authors previously reported satisfying results with NSM after neoadjuvant chemotherapy (NACT). METHODS From 2010 to 2020, 1072 women underwent mastectomy at the authors' institution. In this group, 433 NSMs were performed (40%). The only contraindications to NSM were close proximity to the nipple-areola complex (NAC), bloody discharge, and Paget disease. RESULTS In 112 cases involving 111 women, NSM followed NACT (group 1), whereas it was performed as primary surgery in 321 instances involving 306 women (group 2). At 5 years, local relapse was 7% in group 1 and 2% in group 2, although in the multivariate analysis, locoregional relapses (LRRs) did not differ between the two groups. An increased incidence of local relapse was associated with higher tumor stage (stage III; p = 0.046) and age younger than 51 years (p = 0.038). For 34 (30.3%) of the 111 women in group 1 with a pathologic complete response (pCR), no LRRs were recorded. Only one NAC recurrence was observed. Overall survival with each tumor stage did not differ between the two groups. No differences in complications were observed. Cosmetic results were satisfying in 83.8% of the cases and did not get worse after NACT. CONCLUSIONS The study data definitively confirm that NSM is safe even after NACT, with good cosmetic results and complications comparable with those in the primary surgery setting. Tumor stage and age were the only independent factors for local relapse. Patients with pCR enjoyed optimal locoregional control.

Abstract
BACKGROUND Residual fibroglandular breast tissue (RFGT) following a mastectomy has been claimed to be associated with the occurrence of an in-breast local recurrence (IBLR) or new primary tumor (NP). Yet, scientific evidence proving this assumption is lacking. The primary aim of the study was to verify whether RFGT following a mastectomy is a risk factor for an IBLR or NP. METHODS This retrospective analysis included all patients that underwent a mastectomy and were followed up at the Department of Obstetrics and Gynecology of the Medical University of Vienna between 01.01.2015 and 26.02.2020. RFGT volume (assessed on magnetic resonance imaging) was correlated with the prevalence of an IBLR and a NP. RESULTS A total of 105 patients (126 breasts) following a therapeutic mastectomy were included. After a mean follow-up of 46.0 months an IBLR had occurred in 17 breasts and a NP in 1 breast. A significant difference in RFGT volume was observed between the disease-free cohort and the subgroup with an IBLR or NP (p = .017). A RFGT volume of ≥ 1153 mm3 increased the risk by the factor 3.57 [95%CI 1.27; 10.03]. CONCLUSIONS RFGT volume is associated with an increased risk for an IBLR or NP.

Abstract
Nipple-sparing mastectomy is an alternative to skin-sparing mastectomy in select patients. Increasing evidence supports its use in the setting of breast cancer, however concerns still exist regarding oncological safety. The aim of this systematic review was to evaluate long-term oncological outcomes of patients who underwent nipple-sparing mastectomy for breast cancer. A systematic review of the literature was performed to evaluate oncological outcomes in patients with breast cancer who underwent nipple-sparing mastectomy. Five major databases (PubMed, Embase, Scopus, Web of Science and Cochrane) were searched. The review included all original articles published in English reporting long-term oncological outcomes. 2334 studies were identified. After applying inclusion and exclusion criteria, 17 retrospective studies involving 7107 patients were included. The indication for nipple-sparing mastectomy was invasive carcinoma in 6069 patients (85.4%) and in situ disease in 1038 (14.6%). Median follow up was 48 months (range 25-94). The weighted mean rates of local recurrence and recurrence involving the nipple-areola complex were 5.4% (0.9-11.9) and 1.3% (0-4.9), respectively. The weighted mean distant failure rate was 4.8% (1.5-23.0). Therapeutic nipple-sparing mastectomy is oncologically safe in select patients with breast cancer.

Abstract
BACKGROUND Little information is available about the clinical and pathologic characteristics of local recurrence (LR) after nipple-sparing mastectomy according to the locations of LR. METHODS This study classified 99 patients into the following two groups according to the location of LR after nipple-sparing mastectomy: nipple-areolar recurrence (NAR) group and other locations of LR (oLR) group. The study evaluated whether the location of LR was associated with disease-free survival (DFS) after LR resection. RESULTS For about half of the patients (44.4 %) with NAR, the primary cancer was estrogen receptor (ER)-negative and human epidermal growth factor receptor 2 (HER2)-positive. Conversely, in most of the patients with oLR (79.2 %), the primary cancer was ER-positive and HER2-negative. Among the LR tumors, the frequency of noninvasive carcinoma in the NAR tumors was significantly higher than in the oLR tumors (51.9 % vs 4.2 %, respectively). During a median follow-up period of 46 months, the location of LR was not associated with DFS after LR. In the NAR group, the presence or absence of LR tumor invasiveness was the only factor associated with DFS. In the oLR group, age at primary surgery was the only factor associated with DFS. CONCLUSION This multi-institutional retrospective study demonstrated that the features of NAR, such as the characteristics of the primary and recurrent tumors and the prognostic factors after LR resection, were quite different from those of oLR.

Oncologic Safety of Nipple-Sparing Mastectomy for Breast Cancer in BRCA Gene Mutation Carriers: Outcomes at 70 Months Median Follow-Up. Ann Surg Oncol 2023; 30:3215-3222. [PMID: 36604360 DOI: 10.1245/s10434-022-13006-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Accepted: 12/04/2022] [Indexed: 01/07/2023]
Abstract
BACKGROUND Retention of the nipple-areola complex with nipple-sparing mastectomy (NSM) techniques provides a more natural cosmetic result than procedures that sacrifice the nipple. While the oncologic safety of NSM is established by several studies, there is little long-term data on outcomes in BRCA mutation carriers with breast cancer. PATIENTS AND METHODS BRCA1/2 mutation carriers who underwent NSM and immediate reconstruction from 2008 to 2019 were reviewed and patients with breast cancer on biopsy or final pathology were included. Patient demographics and tumor characteristics, as well as treatment, recurrence, and survival data were collected. RESULTS A total of 114 therapeutic NSM were performed in 105 BRCA mutation carriers (56 BRCA1, 47 BRCA2, and two women with both mutations). Median age was 45 years. Cancers were 18% stage 0, 52% stage I, 27% stage II, and 3% stage III. Mean invasive tumor size was 1.6 cm and 33 (35%) invasive tumors were triple negative. There were five (4.4%) positive nipple margins on final pathology; all underwent nipple excision. Most patients (80, 76%) received systemic therapy: 65 (62%) received chemotherapy and 48 (46%) received endocrine therapy. At 70 months median follow-up (range 15-150 months), no patient had developed a recurrence in the retained nipple-areola complex or at the site of a nipple excised for a positive margin. The rate of locoregional recurrence outside the nipple was 2.6%, and the rate of distant recurrence was 3.8%. Overall survival was 96%. CONCLUSIONS NSM is a safe option for BRCA1 and BRCA2 mutation carriers who undergo mastectomy for breast cancer.

Suggestion for the omission of post-mastectomy chest wall radiation therapy in patients who underwent skin-sparing/nipple-sparing mastectomy. Breast 2022; 66:54-61. [PMID: 36179501 PMCID: PMC9526229 DOI: 10.1016/j.breast.2022.09.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Revised: 08/24/2022] [Accepted: 09/19/2022] [Indexed: 12/27/2022] Open
Abstract
AIM Both skin-sparing mastectomy (SSM) and nipple-sparing mastectomy (NSM) have been widely adopted. Although postmastectomy radiation therapy (PMRT) can improve clinical outcomes, it can worsen cosmesis following reconstruction. Therefore, identifying risk factors of ipsilateral breast tumor recurrence (IBTR) could help de-escalate PMRT after NSM/SSM in patients with pT1-2 disease. METHODS We retrospectively reviewed patients treated with SSM (N = 400) and NSM (N = 156) in patients with pT1-2N0-1 disease between 2009 and 2016. Seventy-four patients received PMRT with 50-50.4 Gy in 25-28 fractions. The Cox proportional hazards model was used to analyze the prognostic factors of IBTR. RESULTS With a median follow-up of 66.2 months, 17 IBTR events were observed, with 5-year IBTR-free rate of 97.2%. Although only one IBTR was observed after PMRT, there was no statistical difference in the 5-year IBTR-free rate (PMRT vs. no PMRT, 98.6% vs. 97.0%, p = 0.360). Multivariable analyses demonstrated that age ≤45 years and lymphovascular invasion (LVI) were adverse features of IBTR. The low-risk group (0 risk factor) showed a better 5-year IBTR-free rate than the high-risk group (≥1 risk factor) (100.0% vs. 95.8%, p = 0.003). In the high-risk group, PMRT slightly improved 5-year IBTR-free rate compared with no PMRT (98.6% vs. 95.2%, p = 0.166). In addition, PMRT increased 5-year cumulative incidence of reconstruction failure (10.0% vs. 2.8%, p = 0.001). CONCLUSION We identified risk factors (age and LVI) related to IBTR following upfront SSM/NSM with pT1-2 disease. As a hypothesis-generating study, de-escalation of PMRT by omitting chest wall irradiation in selective patients could improve reconstruction-related complications without compromising oncologic outcomes.

Abstract
OBJECTIVE The presence of an extensive intraductal component is associated to an increasing risk of relapse in the nipple-areola complex. The aim of the present study was to evaluate the outcomes of patients diagnosed with ductal carcinoma in situ (DCIS) who underwent nipple-sparing mastectomy (NSM) with immediate breast reconstruction using silicone implants. METHODS We retrospectively analyzed the postoperative complications and oncological safety of 67 breast cancer patients diagnosed with pure DCIS who underwent NSM with immediate breast reconstruction using silicone implants between 2004 and 2018. RESULTS Among the 127 NSM procedures performed, 2 hematomas (1.5%) and 1 partial nipple necrosis (0.7%) were observed. After a mean follow-up of 60 months, the local recurrence rate was of 8.9%, the disease-free survival rate was of 90%, and 1 of the patients died. CONCLUSION Despite the local recurrence rate, we showed that NSM with immediate breast reconstruction using silicone implants is a feasible surgical approach, with a low rate of complications and high survival rates for patients with a diagnosis of pure DCIS when breast-conserving surgery is not an option.

Abstract
INTRODUCTION Nipple-sparing mastectomy (NSM) with immediate breast reconstruction (IBR) is increasingly used for both breast cancer (TNSM) and risk reduction (RRNSM). The aim of the study is to report the results of the INSPIRE registry assessing health-related quality of life (HRQoL) comparing baseline and 1-year follow-up, regarding surgical indications and chemotherapy (CT) received. METHODS INSPIRE is a prospective database including women undergoing NSM and IBR from 18 countries. HRQoL was measured using EORTC QLQC30 and QLQ-BR23 before surgery and after 1 year. RESULTS A total of 677 women were included, of whom 537 (79.3%) underwent TNSM and 140 (21.6%) RRNSM: in total, 806 NSM (556 TNSM and 250 RRNSM). Nipple involvement was present in 7.73% of TNSM and incidental carcinoma in 1.2% of the RRNSM group. Out of the overall 537 patients with systemic treatment, 177 (32.96%) received neoadjuvant chemotherapy (NCT) and 118 (21.92%) adjuvant chemotherapy (CT). A total of 227 patients (28.16%) developed at least one complication postoperatively, 164 (29.5%) in the TNSM group and 63 (25.2%) in the RRNSM group. The TNSM group improved in global health status and emotional functioning after 1 year. No differences were found when comparing HRQoL at 1 year between patients who received NCT and those who received adjuvant CT. The RRNSM group showed improvement in HRQoL, with better emotional functioning and fatigue after 1 year. CONCLUSIONS This registry reports HRQoL findings after NSM. The impact of CT on worse HRQoL is independent from its timing. Patients with RRNSM showed an improved HRQoL at 1-year follow-up. Discussion of HRQoL outcomes with patients will facilitate the informed decision-making when considering NSM.

Abstract
Context While analyzing locoregional recurrences (LRRs), it is necessary to consider distant metastasis as a competing event. Because, later one is more fatal than LRR. It may change ongoing treatment of breast cancer and may alter the chance of LRR. Although some earlier studies assessed the effect of neoadjuvant chemotherapy (NACT) on LRR, they did not use competing risk regression model for it. Aims To identify the risk factors and predict LRR using competing risk hazard model and to compare them with those using conventional hazard model. Settings and Design This was a retrospective study from a tertiary care cancer hospital in India. Subjects and Methods Data of 2114 breast cancer patients undergoing surgery were used from patient's record files (1993-2014). Statistical Analysis Fine and Gray competing risk regression was used to model time from surgery to LRR, considering distant metastasis and death as the competing events. Further, cause-specific Cox regression was used to model time from surgery to LRR without considering competing risk. Results Greater than ten positive nodes (hazard ratio [HR] [95% confidence interval (CI)]: 2.19 [1.18-4.03]), skin involvement (HR [95% CI]: 2.75 [1.50-5.05]), NACT (HR [95% CI]: 1.90 [1.06-3.40]), invasive tumor in inner quadrant (HR [95% CI]: 1.78 [0.98-3.24]), and postoperative radiotherapy (HR [95% CI]: 0.52 [0.29-0.94]) were found to be significantly associated with LRR. However, conventional survival analysis ignoring competing risk overestimated cumulative incidence function and underestimated survival. Competing risk regression provided relatively more precise CI. Conclusions: Competing risks, if any, need to be incorporated in the survival analysis. NACT was found to be associated with higher risk for LRR, which may be because of administering it mainly to patients with bad prognosis. Conclusions Competing risks, if any, need to be incorporated in the survival analysis. NACT was found to be associated with higher risk for LRR, which may be because of administering it mainly to patients with bad prognosis.

Abstract
Background Despite that breast conservative therapy became the standard of care in breast cancer, modified radical mastectomy, a large mutilating surgery, is still required for an important number of patients. In order to improve the quality of life and the psychological aspects of a surgery involving the femininity of woman, we developed a new less invasive procedure called infra-radical mastectomy. It aims to save the neckline of patients by the maintenance of the peripheral skin-fatty flap that constitutes the base for implantation of the breast. This phase I study analyzed the feasibility of this procedure using outcome of anatomo-pathological analyses as primary endpoint. Methods Between March 2015 and July 2017, all women with operable breast cancer without signs of lymph node invasion were invited to participate in the study in the 2 participating institutions. After a water-assisted dissection of the peri-glandular space, an enucleation of the breast was performed by a cold knife which represents the infra-radical mastectomy. A peri-glandular re-excision (PGR) of the skin and the fat tissue surrounding the gland was then achieved to obtain an MRM. This PGR underwent a careful pathological examination (10 samples per patient). Moreover, the tissue volume and the skin surface of the PGR were quantified. Results A total of 53 patients (median age: 60 years) were prospectively recruited. The pathological analysis of peri-glandular biopsies revealed none residual invasive carcinoma, 1% of biopsies contained focal ductal carcinoma in situ (DCIS) and 0.4% atypical hyperplasia corresponding to 4 and 2 patients respectively. These 4 patients with residual DCIS were preoperatively diagnosed with extensive DCIS. On average after an infra-radical mastectomy, 37% of the volume and 53% of the skin surface of a complete modified radical mastectomy were sparred. Conclusions The evaluation of biopsies from peri-glandular tissue suggests that infra-radical mastectomy should be further evaluated except for patients diagnosed with extensive DCIS which must be excluded of this infra-radical approach. Additional work is needed to evaluate cosmetic outcome and impact on quality of life, the need of radiotherapy and the oncological long-term outcome.

A novel MRI-based predictive index can identify patients suitable for preservation of the nipple-areola complex in breast reconstructive surgery. Eur J Surg Oncol 2020; 47:225-231.

Abstract
INTRODUCTION Accurately predicting nipple-areola complex (NAC) involvement in breast cancer is necessary for identifying patients who may be candidates for a nipple-sparing mastectomy. Although multiple risk factors are indicated in the guidelines, it is difficult to predict NAC involvement (NAC-i) preoperatively even if these factors are evaluated individually. This study aimed to develop a more accurate and practical preoperative NAC-i prediction model using magnetic resonance imaging (MRI). MATERIALS AND METHODS All tumors in 252 patients were evaluated using postcontrast T1-weighted subtraction on MRI. RESULTS The receiver operating characteristic curves identified cut-off values for tumor size and tumor-to-nipple distance (TND) as 4 cm and 1.2 cm, respectively. Multivariate analysis demonstrated that TND (p < 0.001), ductal enhancement extending to the nipple (DEEN) (p < 0.001), and nipple enhancement (NE) (p = 0.005) were independent clinical risk factors for pathological NAC-i. A formula was constructed using odds ratios for these three independent preoperative risk factors in multivariate analysis: the MRI-based NAC-i predictive index (mNACPI) = TND × 4 + DEEN × 3 + NE × 1. A total score of ≤4 points was defined as low risk and ≥5 points as high risk. NAC-i rates were 2.4% in the low-risk group and 89.4% in the high-risk group; a significant correlation was observed between the risk group and permanent pathological NAC-i (p < 0.001). Assuming that the NAC was preserved in low-risk patients and resected in high-risk patients, NAC-i was verified using the mNACPI. CONCLUSION mNACPI may contribute greatly to the improvement of selecting suitable patients for NAC preservation in breast reconstructive surgery while maintaining oncological safety.

Abstract
Nipple-sparing mastectomy (NSM) is a valid option for carefully selected cases. Oncologic guidelines have not been established, but proximity of the tumor to the nipple, tumor size, lymph node involvement, and neoadjuvant chemotherapy have been suggested as contraindications to nipple preservation. This study describes our experience with NSM in relation to these factors, in particular distance of tumor from the nipple, to help establish evidence-based guidelines for NSM.

Abstract
BACKGROUND This study aimed to analyze our 11-year experience using NSM with immediate breast reconstruction in breast cancer. METHODS Between January 2007 and December 2015, 251 NSMs were performed on 251 women with breast cancer for therapeutic purpose at Pusan National University Hospital. RESULTS The clinical and pathologic mean tumor size was 3.1 cm. Based on preoperative imaging, mean distance between tumor and nipple was 2.5 cm. Among 251 tumors, 119 cases (47.4%) and 69 cases (27.5%) with a distances ≤ 2 cm and ≤ 1 cm, respectively, were detected. There were 11 patients (4.4%) with locoregional recurrences during the mean follow-up period of 68.0 months. Of these 11 cases, one (0.4%) had local recurrence in the retained NAC, and the others had recurrence in the chest wall or skin. CONCLUSION Unless clinical and histological evidence of nipple involvement, NSM can be an oncologically safe surgical option for breast cancer, even if the tumor is located close to the nipple.

Abstract
OBJECTIVES To evaluate the oncologic outcomes and risk factors for locoregional recurrence (LRR) and nipple-areola complex recurrence (NR) in a large series of breast cancer patients who underwent nipple-sparing mastectomy (NSM) and immediate reconstruction after neoadjuvant chemotherapy (NACT). SUMMARY OF BACKGROUND DATA The use of NSM and immediate reconstruction in breast cancer patients receiving NACT is increasing. However, the oncologic safety of this approach is unclear. PATIENTS AND METHODS A total of 310 breast cancer patients (319 breasts) who underwent NACT and NSM between February 2010 and November 2016 were retrospectively analyzed. Clinical and pathologic factors associated with increased risks of LRR and NR were analyzed using univariate (Chi-square or Fisher exact test) and multivariate (Cox proportional hazard regression model) analyses. RESULTS During a mean follow-up of 63 ± 22 months, 38 cases had LRR as the first event, including 6 cases of NR as the first event. The 5-year cumulative LRR and NR rates were 11.0% and 1.9%, respectively. In univariate analysis, clinical T stage, pathologic nodal status, histologic grade, lymphovascular invasion, and post-NACT Ki67 status were associated with increased LRR risk, and post-NACT Ki67 status was the only significant risk factor for NR. In multivariate analysis, post-NACT Ki67 ≥10% (hazard ratio, 4.245; 95% confidence interval, 1.865-9.663; P = 0.001) was an independent risk factor for LRR. CONCLUSIONS NSM and immediate reconstruction seem to be oncologically safe with acceptable LRR and NR rates for appropriately selected breast cancer patients treated with NACT. Post-NACT Ki67 ≥10% was associated with increased risk of LRR or NR, and therefore, necessitates cautious follow-up.

J Plast Reconstr Aesthet Surg 2020; 73:1514-1525. [PMID: 32238306 DOI: 10.1016/j.bjps.2020.02.021] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2019] [Revised: 01/01/2020] [Accepted: 02/09/2020] [Indexed: 12/16/2022]
Abstract
BACKGROUND Robotic nipple sparing mastectomy (R-NSM), which uses the da Vinci surgical platform, could perform NSM and immediate breast reconstruction through a small and inconspicuous extra-mammary axillary or lateral chest incision. R-NSM was reported with extremely low nipple areolar complex (NAC) necrosis rate, good cosmetic results, and high patient satisfaction. However, there was little evidence available comparing the effectiveness and safety of R-NSM and conventional NSM (C-NSM) in the management of breast cancer. METHODS A case control comparison study was conducted for patients with breast cancer who underwent R-NSM or C-NSM with immediate gel implant breast reconstruction (IGBR) from July 2011 to September 2019 at a single institution to compare the clinical outcomes, patient-reported esthetic results, and medical cost. RESULTS According to the study design, 54 procedures of R-NSM were compared with 62 procedures of C-NSM in the surgical management of breast cancer combined with IGBR. Compared with C-NSM, R-NSM was associated with higher overall satisfaction (92% excellent and 8% good versus 75.6% excellent and 24.4% good, P = 0.046), and wound/scar related outcome in patient-reported esthetic results. The NAC ischemia/necrosis risk, overall complication rate, and blood loss were not significantly different between R-NSM and C-NSM groups. However, longer operation time and higher overall medical cost (10,877 ± 796 versus 5,702 ± 661 US Dollars, P<0.01) was observed in R-NSM group. CONCLUSION Compared with C-NSM, R-NSM showed comparable clinical outcomes and favorable patients' satisfaction with the esthetic results, but at the price of longer operation time and higher cost.

Abstract
BACKGROUND Nipple-sparing mastectomy (NSM) has become increasingly prevalent for patients with ductal carcinoma in situ (DCIS) requiring mastectomy. However, few data regarding recurrence outcomes after NSM are available for this patient population. This study evaluated the locoregional recurrence (LRR) rate for patients with pure DCIS who underwent NSM followed by immediate breast reconstruction without adjuvant radiotherapy and investigated potential risk factors for LRR and/or nipple-areola complex recurrence (NR). METHODS A retrospective chart review was performed for 199 consecutive patients with pure DCIS who underwent NSM and immediate breast reconstruction between March 2003 and December 2015. Risk factors for LRR and NR were analyzed using univariate (Chi square test) and multivariate (Cox model) methods. RESULTS The median follow-up duration after surgery was 97 months (range, 39-186 months). At 10 years, the LRR rate was 4.5%, and the NR rate was 3%. The univariate analysis showed that high nuclear grade, negative receptor status, positive human epidermal growth factor receptor 2 (HER2) status, and negative hormone receptor/positive HER2 subtype were associated with increased risk for NR. The multivariate analysis demonstrated that negative progesterone receptor status was an independent risk factor for LRR. However, margin status and tumor-to-nipple distance (TND) were not associated with increased risk for either LRR or NR. CONCLUSIONS The study findings suggest that NSM can be a feasible surgical option even for DCIS with a TND of 1 cm or less if the retroareolar resection margin is negative for malignancy. Determining the molecular subtype of DCIS might be helpful in identifying patients at high risk for recurrence.

Abstract
BACKGROUND Nipple-sparing mastectomy (NSM) is increasingly performed for invasive breast cancer. Growing evidence supporting the oncologic safety of NSM has led to its widespread use and broadened indications. In this study, we examine the indications, complications, and long-term outcomes of therapeutic NSM. METHODS From 2003 to 2016, women undergoing NSM for invasive cancer or ductal carcinoma in situ (DCIS) were identified from a prospectively maintained database. Patient and disease characteristics were compared by procedure year, while complications were compared by procedure year using generalized mixed-effects models accounting for a random surgeon effect. Overall survival and time to recurrence were examined. RESULTS Of the 467 therapeutic NSMs, 337 (72%) were invasive cancer, 126 (27%) were DCIS, and 4 (1%) were phyllodes tumors. Median age was 45 years (range 24-75) and median follow-up among survivors was 39.4 months. Three hundred and fifty-seven (76.4%) cases were performed in 2011 or after. When comparing NSMs performed before and after 2011, there was a significant increase in NSMs performed for invasive tumors (58% vs. 77%; p < 0.001). There was no difference in family history, genetic mutations, smoking status, neoadjuvant chemotherapy, prior radiation, nodal involvement, or tumor subtype. Twenty-one (4.5%) nipple excisions were performed, of which 14 were performed for cancer at the nipple margin. Forty-four breasts (9.4%) had complications that required re-operation. Fifteen patients had locoregional recurrence or distant metastasis. CONCLUSIONS NSM use for invasive carcinoma has doubled at our institution since 2011, while postoperative complications and recurrence rates remain low. Our experience supports the selective use of NSM in the malignant setting with careful patient selection.

Abstract
Importance The main concern associated with nipple-sparing mastectomy (NSM) is the risk of local breast cancer recurrence at the retained nipple-areola complex (NAC) consequent to occult nipple involvement. Long-term follow-up data regarding the oncologic safety of modern therapeutic NSM in terms of cancer recurrence at the NAC and survival are limited. Objective To assess the incidence, risk factors, treatment, and long-term outcomes associated with cancer recurrence at the NAC in a large series of patients with invasive breast cancer who underwent NSM and immediate breast reconstruction. Design, Setting, and Participants In this retrospective cohort study at a single institution (Asan Medical Center) in Seoul, Republic of Korea, 962 breasts from 944 patients who underwent NSM and immediate breast reconstruction for invasive breast cancer were analyzed between March 3, 2003, and December 31, 2015. Patients who underwent neoadjuvant systemic therapy or palliative surgery were excluded. Data analysis was performed from June 4, 2018, to August 31, 2018. Main Outcomes and Measures Univariate and multivariate Cox proportional hazards regression models were used to analyze the association between clinicopathologic variables and cancer recurrence at the NAC. To evaluate the association between cancer recurrence at the NAC and prognosis, distant metastasis-free survival, and overall survival were estimated using the Kaplan-Meier method and compared using the log-rank test. Results Among the 944 study patients (median age at diagnosis, 43 years [range, 23-67 years]) during a median follow-up of 85 months (range, 14-185 months), 39 cases (4.1%) of cancer recurrence at the NAC were identified as the first event after NSM. The 5-year cumulative incidence of cancer recurrence at the NAC was 3.5% (n = 34). In multivariate analyses, multifocality or multicentricity (hazard ratio [HR], 3.309; 95% CI, 1.501-7.294; P = .003), negative hormone receptor or ERBB2 (formerly HER2 or HER2/neu)-positive subtype (HR, 3.051; 95% CI, 1.194-7.796; P = .02), high histologic grade (HR, 2.641; 95% CI, 1.132-6.160; P = .03), and extensive intraductal component (HR, 3.338; 95% CI, 1.262-8.824; P = .02) were independently associated with cancer recurrence at the NAC after NSM. All 39 recurrent cases involved wide local excision. Patients with and without cancer recurrence at the NAC as the first event did not differ significantly with regard to distant metastasis-free survival (P = .95) or overall survival (P = .21). The 10-year distant metastasis-free survival rates were 89.3% among patients with cancer recurrence at the NAC and 94.3% among patients without recurrence. The 10-year overall survival rates were 100% among patients with cancer recurrence at the NAC and 94.5% among those without recurrence. Conclusions and Relevance Patients had a low incidence of cancer recurrence at the NAC after NSM and immediate breast reconstruction in this study. The findings suggest that multifocal or multicentric disease, hormone receptor-negative/ERBB2-positive subtype, high histologic grade, and positive extensive intraductal component should be considered before determining the NSM procedure.

Abstract
Purpose Although the indications for nipple-sparing mastectomy (NSM) are expanding, there remains a debate regarding the oncologic outcomes of patients treated with this method, especially those with a short tumor–nipple distance (STND). The aim of this study was to compare the long-term oncologic outcomes between patients with a long tumor–nipple distance (LTND) (≥ 2.0 cm) and those with STND (< 2.0 cm). Methods This was a retrospective study in which 266 patients who underwent NSM with immediate breast reconstruction between January 2008 and December 2014 at a single institution were enrolled. Of these patients, 21 were excluded because of loss to follow-up; thus, 245 patients were finally analyzed. All patients underwent preoperative breast magnetic resonance imaging and intraoperative frozen biopsy. Results The mean age of the patients was 42.4 years. STND was identified in 128 patients, and LTND in 117 patients. The mean follow-up period was 60.5 months. There were no significant differences between the 2 groups with respect to lymphovascular invasion, nuclear grade, nodal status, and subtype (p = 0.339, 0.372, 0.955, and 0.338, respectively). The STND group had significantly smaller tumors than the LTND group (p = 0.005). The median TND in the STND and LTND groups was 0.7 cm and 3.0 cm, respectively. Locoregional recurrence was reported in 4 patients in the STND group (3.1%) and 6 (5.1%) in the LTND group. A total of 3 patients died (1.2%; 2 in the STND group and one in the LTND group). There was no significant difference between the 2 groups with respect to disease-free survival or local recurrence-free survival (p = 0.334 and p = 0.477, respectively). Conclusion The long-term oncologic outcomes of patients treated with NSM did not significantly differ according to TND when the intraoperative frozen biopsy was negative for tumor cells.

Nipple-sparing mastectomy: external validation of a three-dimensional automated method to predict nipple occult tumour involvement on preoperative breast MRI. Eur Radiol Exp 2019; 3:31. [PMID: 31388834 PMCID: PMC6684692 DOI: 10.1186/s41747-019-0108-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2019] [Accepted: 07/02/2019] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND Preoperative evaluation of nipple-areola complex (NAC) tumour involvement is crucial to select patients candidates for nipple-sparing mastectomy. Our aim was to validate a previously developed automated method able to compute the three-dimensional (3D) tumour-to-NAC distance (the most predictive parameter of nipple involvement), using magnetic resonance imaging (MRI) datasets acquired with a scanner and protocol different from those of the development phase. METHODS We performed a retrospective analysis of 77 patients submitted to total mastectomy and preoperatively studied with MRI. The new method consisted of automated segmentation of both NAC and tumour and subsequent computation of the 3D distance between them; standard manual two-dimensional segmentation was independently performed. Paraffin-embedded section examination of the removed NAC was performed to identify the neoplastic involvement. The ability of both methods to discriminate between patients with and without NAC involvement was compared using receiver operating characteristic (ROC) analysis. RESULTS The 3D tumour-to-NAC distance was correctly computed for 72/77 patients (93.5%); tumour and NAC segmentation method failed in two and three cases, respectively. The diagnostic performance of the 3D automated method at best cut-off values was consistently better than that of the 2D manual method (sensitivity 78.3%, specificity 71.4%, positive predictive value 87.5%, negative predictive value 56.3%, and AUC 0.77 versus 73.9%, 61.2%, 47.2%, 83.3%, and 0.72, respectively), even if the difference did not reach statistical significance (p = 0.431). CONCLUSIONS The introduction of the 3D automated method in a clinical setting could improve the diagnostic performance in the preoperative assessment of NAC tumour involvement.

Oncologic outcomes and radiation safety of nipple-sparing mastectomy with intraoperative radiotherapy for breast cancer. Breast Cancer 2019; 26:618-627. [PMID: 30888580 DOI: 10.1007/s12282-019-00962-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2018] [Accepted: 03/11/2019] [Indexed: 10/27/2022]
Abstract
BACKGROUND Nipple-sparing mastectomy combined with breast reconstruction helps to optimize the contour of the breast after mastectomy. However, the indications for nipple-sparing mastectomy are still controversial. Local radiation to the nipple-areola complex may play some roles in improving the oncological safety of this procedure. METHODS From January 2014 to December 2017, 41 consecutive patients who underwent nipple-sparing mastectomy combined with Intrabeam intraoperative radiotherapy to the nipple-areola complex flap and breast reconstruction were enrolled in this prospective study. The prescribed radiation dose at the surface of the spherical applicator was 16 Gy. RESULTS In eight cases, carcinomas were in the central portion of the breast. Partial necrosis of the nipple-areola complex occurred in three cases. Over 90% of patients reported "no or poor sensation" of the nipple-areola complex postoperatively. With a median follow-up time of 26 months, no recurrences or metastases were identified; however, breast-cancer mortality occurred in one patient. Pathologic evaluation of paraffin-embedded sections showed ductal carcinoma in situ in the remaining tissues deep to the nipple-areola complex flap in two patients. Although no further treatment was administered to the nipple-areola complexes postoperatively, no recurrences or metastases were identified 20 months and 24 months later, respectively. Optical microscopy and transmission electron microscopy revealed changes in some normal tissues immediately after Intrabeam intraoperative radiotherapy. Karyopyknosis were observed in gland tissues, and the collagenous fibers became sparse and arranged chaotically. As assessed by thermoluminescence, radiation doses at different sites in the nipple-areola complex flap varied considerably and were about 10 Gy at the areola surface. No Intrabeam intraoperative radiotherapy-related acute or chronic radiation injuries of the lung, heart or bone marrow were identified. CONCLUSIONS Our findings indicate that Intrabeam intraoperative radiotherapy during nipple-sparing mastectomy combined with breast reconstruction is safe and feasible. TRIAL REGISTRATION The current study was approved by the Ethics Committee of the First Affiliated Hospital of Guangzhou Medical University (registering order 201750). All participants gave their written informed consent.

Abstract
OBJECTIVE This study was designed to investigate the presence of residual breast tissue (RBT) after skin-sparing mastectomy (SSM) and nipple-sparing mastectomy (NSM) and to analyse patient- and therapy-related factors associated with RBT. Skin-sparing mastectomy and NSM are increasingly used surgical procedures. Prospective data on the completeness of breast tissue resection is lacking. However, such data are crucial for assessing oncologic safety of risk-reducing and curative mastectomies. METHODS Between April 2016 and August 2017, 99 SSM and 61 NSM were performed according to the SKINI-trial protocol, under either curative (n = 109) or risk-reducing (n = 51) indication. After breast removal, biopsies from the skin envelope (10 biopsies per SSM, 14 biopsies per NSM) were taken in predefined radial localizations and assessed histologically for the presence of RBT and of residual disease. RESULTS Residual breast tissue was detected in 82 (51.3%) mastectomies. The median RBT percentage per breast was 7.1%. Of all factors considered, only type of surgery (40.4% for SSM vs. 68.9% for NSM; P < 0.001) and surgeon (P < 0.001) were significantly associated with RBT. None of the remaining factors, e.g., skin flap necrosis, was associated significantly with RBT. Residual disease was detected in three biopsies. CONCLUSIONS Residual breast tissue is commonly observed after SSM and NSM. In contrast, invasive or in situ carcinomas are rarely found in the skin envelope. Radicality of mastectomy in this trial is not associated with increased incidence of skin flap necrosis. ClinicalTrials.gov Identifier NCT03470909.

Abstract
Nipple-sparing mastectomy is a valuable addition to the options available for women at high risk of developing breast cancer. In this review, we summarize current knowledge about the high-risk genes, BRCA1, BRCA2 and TP53 and the associated guidelines with regard to risk-reducing surgery. We consider other genetic risks and high-risk lesions. We discuss the literature on bilateral mastectomy for breast cancer risk-reduction, and the results of nipple-sparing mastectomy in particular. Finally, we report on patient satisfaction with these procedures and the impact that nipple-sparing mastectomy may have on women at high-risk of breast cancer.

Abstract
The increasing use of nipple-sparing mastectomy (NSM) and skin-sparing mastectomy (SSM) in the treatment of nonmetastatic breast cancer is justified by considerations linked to their therapeutic index. In selected patients, efficacy results tend to be similar to those observed after radical modified mastectomy and at the same time, subcutaneous mastectomies preserve the patient’s body image. Yet the oncologic safety of the two former surgical approaches is still a matter of debate, also in consideration of the almost complete absence of clinical studies directed to prospective, controlled comparisons between subcutaneous and radical modified mastectomies. In addition, no clear statement—and consequently no consensus—emerges from the rather rare reports addressing the issue of whether or not there exist robust algorithms for guiding decision-making in delivering postoperative radiotherapy after NSM or SSM. The objective of the present review article is to revisit the dataset recently provided by the literature, which might help oncology teams optimise local treatment in this patient population.

Abstract
PURPOSE Skin-sparing and nipple-sparing mastectomies (SSM; NSM) remove the breast's fibroglandular tissue (FGT), thereby reducing breast cancer risk. The postoperative presence of residual FGT (RFGT) is associated with remaining cancer risk. This study evaluated the role of MRI in the quantitative assessment of RFGT and its impact on the estimation of the remaining breast cancer risk. METHODS The postoperative MRI scans (following EUSOMA recommendations) of 58 patients who had undergone SSM or NSM between 2003 and 2013, as well as preoperative MRI scans that were available in 25 of these patients, were retrospectively evaluated for the presence and location of RFGT by three radiologists. Two different observers quantitatively assessed the volume and percentage of retromamillary and other RFGT (RFGTrm and RFGTother) were assessed. The Fisher's exact test, the Student's t-test, and intraclass coherence were used to compare patient groups and to assess reproducibility. RESULTS RFGT was found in 20% of all breasts and significantly more frequently after NSM than SSM (50% vs. 13%, p = .003). RFGTrm and RFGTother were more prevalent after NSM (p < 0.001; p = .127). RFGT ranged from 0.5 to 26% of the preoperative FGT, with higher percentages after NSM than SSM (p = .181). CONCLUSIONS The prevalence and percentage of RFGT found on MRI indicate a considerable remaining postoperative breast cancer risk in some women.

Abstract
BACKGROUND In medical oncology, changes in practices are almost always based on randomized trials but medical history shows that it is different in surgical oncology. In the past, many surgical procedures were routinely performed without a rigorous evaluation of the risk-benefit. To highlight the complexity of developing randomized surgical trials, disquisitions on methodology presented in the medical literature. This is particularly true when we consider breast reconstruction after surgical treatment for breast cancer. It is illusory to perform and conduct a randomized clinical trial (RCT) when a surgical procedure is routinely used by most surgeons. METHODS As a case study, we present the scientific rationale and the design of the MAPAM01 trial which evaluates the security of the nipple sparing mastectomy. Other alternative approaches, such as propensity score and CUSUM, are presented. RESULTS In this situation, to design surgical trials using alternative methodological approaches present a particularly important challenge both for surgeons and methodologists. Alternative approach to randomized trials can be useful to evaluate surgical procedures routinely used. CONCLUSION Close collaboration between surgeons and methodologists is needed to propose appropriate and well-designed surgical trials.

Abstract
Although nipple-sparing mastectomy (NSM) is being used more frequently, the oncological safety of NSM remains unclear, particularly in young patients (<35 years). The aim of the present study was to compare the rates of local recurrence (LR), disease-free survival (DFS) and overall survival (OS) in young patients with breast cancer who had undergone NSM or conventional mastectomy (CM). The clinicopathological data of young patients with stage 0-IIB breast cancer who had undergone NSM (163 cases) or CM (194 cases) between 2007 and 2016 were retrospectively analyzed. The log-rank test was used to analyze the differences in the LR, DFS and OS rates between the two groups and multivariate analysis was used to analyze the patient prognostic factors for DFS. The median follow-up time was 49 months. Patients who had undergone CM were more likely to exhibit stage II disease (68.4 vs. 58.3%; P=0.015) and positive lymph nodes (45.9 vs. 33.1%; P=0.014). In the NSM group, LR occurred in 7 (4.3%) cases, systemic recurrence in 15 (9.2%) cases and mortality in 9 (5.5%) cases. In the CM group, LR occurred in 6 (3.1%) cases, systemic recurrence in 27 (13.9%) cases and mortality in 15 (7.7%) cases. There were no statistical differences in the LR, DFS and OS rates between the two groups (P>0.05). Following adjustment for clinical stage, the LR and DFS rates between the two groups exhibited no significant differences. Analysis of the prognostic factors demonstrated that clinical stage, lymph node status, estrogen and progesterone receptor status and human epidermal growth factor receptor 2 status were associated with DFS (P<0.05). NSM is safe for young patients with early-stage breast cancer and provides patients with an improved cosmetic outcome. Furthermore, nipple-areola complex preservation does not increase the risk of recurrence.

Abstract
Background For several years, there has been broad consensus that nipple-sparing mastectomy is a safe surgical treatment for breast cancer. However, the technique is associated with a relatively high risk of local recurrence (LR) behind the nipple-areola complex (NAC). It is for this reason that some years ago we introduced intraoperative radiotherapy with electrons (ELIOT) targeted specifically to the NAC to reduce the probability of recurrence there. However, in some cases we preferred to avoid ELIOT when the NAC appears to have a poor blood supply to ensuring the best chance of NAC survival. Methods From July 2003 to April 2010 at our institute, 30 patients received nipple-sparing mastectomy but neither ELIOT nor external radiotherapy, as the surgeon considered the irradiation would markedly compromise the chances of NAC survival, because of sub-optimal vascularization. Results After a median follow-up of 5 years there were no LRs with minor post-operative complications. Conclusions This preliminary case series indicates that the presented technique can be a safe procedure in breast cancer surgery, but requires greater number of cases and a longer follow-up to confirm the oncological safety.

Abstract
Nipple-sparing mastectomies (NSMs) are increasingly used in the surgical treatment of patients with breast cancer and for prevention of breast cancer. The present study was performed to review the outcomes of patients undergoing NSMs at a single large university setting. A retrospective chart review was performed on all patients undergoing NSMs from 2008-2014. Charts were reviewed for demographic data and patient characteristics. Tumor and breast size, cancer recurrence and complications were also evaluated. Descriptive statistics were utilized to summarize the findings. From 2008-2014, 110 patients underwent 197 NSMs. The mean patient age was 44.4 years (range, 20-77). The average body mass index was 24 (range, 18-47). Breast weight was available for 106 specimens, with a mean weight of 475.5 g (range, 124.1-1,625.0 g). Seventy-three NSMs were performed for cancer and 124 were performed prophylactically. The mean tumor width was 1.38 cm (range, 0-6.0 cm), with an average nipple to tumor distance of 5.87 cm (range, 2.93-10.0 cm). Three (4%) patients required removal of the nipple areolar complex (NAC) due to pathological extension of the tumor. A total of 34 (17.2%) complications occurred, including infections, hematomas and nipple necrosis, with 9 requiring removal of the NAC and 13 requiring removal of the tissue expander or implant. Smokers had a 36.0% (9/25) complication rate, compared with 14.5% (25/172) of nonsmokers (P<0.05). During follow-up, one recurrence was noted, located on the chest wall. There were no recurrences in the NAC group. Therefore, NSMs may safely be performed without compromising oncologic outcomes or increasing complication rates in properly selected patients.

Abstract
BACKGROUND The aim of this study was to investigate clinical outcomes and risk factors related complications in patients who had undergone nipple-sparing mastectomy (NSM) followed by implant-based or autologous reconstruction. METHODS Between 2004-2014 a single-institution retrospective review was collected on NSMs reconstruction. Patient demographics, comorbidities, breast morphological factors, type and timing of radiotherapy, type of incision, reconstruction type and timing, implant volume and complications were collected. RESULTS A total of 288 patients had undergone 369 NSMs, 81 (28.1%) of which were bilateral while 207 (71.9%) unilateral. One-hundred mastectomies were performed for prophylactic purposes whereas 269 were therapeutics. Thirteen (4.5%) patients were active smokers, while 2 (0.7%) were diabetics. Fifty-five breasts (14.9%) were previously irradiated and average time elapsed between radiotherapy and NSM was 9-year, (range, 5-15 yrs). Total complication rate was 13.5% at mean follow-up of 47.98 months (range, 6-114 months). Partial-thickness and full-thickness mastectomy skin flap and NAC necrosis occurred in 39 (78%) and in 10 (20%) breasts, respectively. Previous radiotherapy and implant volume were significant predictors of complications (OR: 10.14, 95% CI: 3.99-27.01; OR × 100 g: 3.13, 95% CI: 1.64-6.33). Overall mastectomy type incision was not predictive of complications (p = .426). No association was observed between radiotherapy and mastectomy type access (p = .349). CONCLUSIONS From our experience NSM followed by implant-based and autologous reconstruction had a relative high rate of complications comparable to previous reports. Despite this, it should be carefully offered to patients in whom potential risk factors are identified.

Abstract
BACKGROUND Nipple-areola complex-sparing mastectomy (NSM), extending the concept of skin-sparing mastectomy, allows for the provision of a better cosmetic result. Large operable T2-T3 breast cancer might theoretically appear suitable for this surgical option as an alternative to conventional mastectomy or breast-conserving surgery, when a good response to primary chemotherapy has been achieved. PATIENTS AND METHODS From January 2009 to May 2013, 422 patients with invasive breast cancer were progressively accrued to NSM. Of the 422 patients, 361 underwent NSM as first-line treatment (NSM group), and 61 underwent surgery after primary chemotherapy (NSM-PC group). A total of 151 breast cancer patients, who had undergone PC and conventional total mastectomy (TM-PC group) from 2004 to 2009 were evaluated as comparative group with respect to the NSM-PC group. Using propensity score matching, local disease-free survival (LDFS) was evaluated comparatively. RESULTS The rate of nipple-areola involvement in the NSM and NSM-PC groups was 13.3% and 9.8%, respectively (P = .539). The nipple-areola involvement in the NSM and NSM-PC groups was significantly associated with the tumor size (odds ratio [OR], 1.48; 95% confidence interval [CI], 1.13-1.95; P = .004), plurifocal or pluricentric tumor (OR, 3.18; 95% CI, 1.72-5.89; P < .001), and the presence of an intraductal component (OR, 2.38; 95% CI, 1.22-4.64; P = .011). The LDFS in the NSM-PC and TM-PC matched cohorts did not show a significant difference, with a 4-year LDFS of 0.89 (95% CI, 0.77-0.95) and 0.93 (95% CI, 0.83-0.97), respectively (hazard ratio [HR], 1.31; 95% CI, 0.40-4.35; P = .655). The NSM-PC cohort was also compared with the NSM cohort in terms of LDFS using 2 different matching criteria, with the tumor size before and after neoadjuvant chemotherapy as the balancing covariate. In the first of the 2 comparisons, the hazards of local relapse were comparable between the 2 matched groups (HR, 1.23; 95% CI, 0.37-4.04; P = .739). In the second comparison, the NSM-PC patients showed a significant greater hazard of local relapse than did the NSM patients (HR, 3.60; 95% CI, 1.10-11.80; P = .035). CONCLUSION NSM might be a valuable option for large breast cancer treated by primary chemotherapy. The rate of local relapse seemed to be related to the disease stage, and no significant association with the type of surgery was detected.

Abstract
OBJECTIVE To perform a meta-analysis to determine the effect of radiotherapy (RT) on nipple-areolar complex (NAC) and skin flap necrosis, and local recurrence in women who undergo nipple-sparing mastectomy (NSM) and immediate breast reconstruction. METHODS Medline, PubMed, Cochrane, and Google Scholar databases were searched until October 16, 2015. Randomized-controlled-trials, prospective, retrospective, and cohort studies were included. The primary outcome was the NAC necrosis rate, and the secondary outcomes were the skin flap necrosis and local recurrence rates. RESULTS Of 186 studies identified, 2 prospective and 5 retrospective studies including a total of 3692 patients were included in the meta-analysis. Five, 3, and 2 studies reported data of NAC necrosis (3461 breasts), skin flap necrosis (2490 breasts), and local recurrence (988 breasts), respectively. Pooled results showed no difference in the odds of NAC necrosis [odds ratio (OR) = 1.250, 95% confidence interval (CI) 0.481-3.247, P = 0.647], or local recurrence (OR = 0.564, 95% CI 0.056-5.710, P = 0.627) between patients who received and did not receive RT. Patients treated with RT had a higher likelihood of skin flap necrosis (OR = 2.534, 95% CI 1.720-3.735, P < 0.001). Significant heterogeneity, however, was noted in the analysis of NAC and local recurrence. CONCLUSIONS Because of the limitations of the small number of studies and heterogeneity in the analysis, this study does not allow drawing any definitive conclusions and highlights the need of well-controlled trials to determine the effect of RT in patients undergoing NSM.

Abstract
BACKGROUND The efficacy and safety of nipple-sparing mastectomy and areola-sparing mastectomy for the treatment of breast cancer are still questionable. It is estimated that the local recurrence rates following nipple-sparing mastectomy are very similar to breast-conserving surgery followed by radiotherapy. OBJECTIVES To assess the efficacy and safety of nipple-sparing mastectomy and areola-sparing mastectomy for the treatment of ductal carcinoma in situ and invasive breast cancer in women. SEARCH METHODS We searched the Cochrane Breast Cancer Group's Specialized Register, the Cochrane Center Register of Controlled Trials (CENTRAL), MEDLINE (via PubMed), Embase (via OVID) and LILACS (via Biblioteca Virtual em Saúde [BVS]) using the search terms "nipple sparing mastectomy" and "areola-sparing mastectomy". Also, we searched the World Health Organization's International Clinical Trials Registry Platform and ClinicalTrials.gov. All searches were conducted on 30th September 2014 and we did not apply any language restrictions. SELECTION CRITERIA Randomised controlled trials (RCTs) however if there were no RCTs, we expanded our criteria to include non-randomised comparative studies (cohort and case-control studies). Studies evaluated nipple-sparing and areola-sparing mastectomy compared to modified radical mastectomy or skin-sparing mastectomy for the treatment of ductal carcinoma in situ or invasive breast cancer. DATA COLLECTION AND ANALYSIS Two review authors (BS and RR) performed data extraction and resolved disagreements. We performed descriptive analyses and meta-analyses of the data using Review Manager software. We used Cochrane's risk of bias tool to assess studies, and adapted it for non-randomised studies, and we evaluated the quality of the evidence using GRADE criteria. MAIN RESULTS We included 11 cohort studies, evaluating a total of 6502 participants undergoing 7018 procedures: 2529 underwent a nipple-sparing mastectomy (NSM), 818 underwent skin-sparing mastectomy (SSM) and 3671 underwent traditional mastectomy, also known as modified radical mastectomy (MRM). No participants underwent areola-sparing mastectomy. There was a high risk of confounding for all reported outcomes. For overall survival, the hazard ratio (HR) for NSM compared to SSM was 0.70 (95% CI 0.28 to 1.73; 2 studies; 781 participants) and the HR for NSM compared to MRM was 0.72 (95% CI 0.46 to 1.13; 2 studies, 1202 participants). Local recurrence was evaluated in two studies, the HR for NSM compared to MRM was 0.28 (95% CI 0.12 to 0.68; 2 studies, 1303 participants). The overall risk of complications was different in NSM when compared to other types of mastectomy in general (RR 0.10, 95% CI 0.01 to 0.82, 2 studies, P = 0.03; 1067 participants). With respect to skin necrosis, there was no evidence of a difference with NSM compared to other types of mastectomy, but the confidence interval was wide (RR 4.22, 95% CI 0.59 to 30.03, P = 0.15; 4 studies, 1948 participants). We observed no difference among the three types of mastectomy with respect to the risk of local infection (RR 0.95, 95% CI 0.44 to 2.09, P = 0.91, 2 studies; 496 participants). Meta-analysis was not possible when assessing cosmetic outcomes and quality of life, but in general the NSM studies reported a favourable aesthetic result and a gain in quality of life compared with the other types of mastectomy. The quality of evidence was considered very low for all outcomes due to the high risk of selection bias and wide confidence intervals. AUTHORS' CONCLUSIONS The findings from these observational studies of very low-quality evidence were inconclusive for all outcomes due to the high risk of selection bias.

The Oncological Safety of Nipple-Sparing Mastectomy: A Systematic Review of the Literature with a Pooled Analysis of 12,358 Procedures. Arch Plast Surg 2016; 43:328-38.

Abstract
Nipple-sparing mastectomy (NSM) is increasingly popular as a procedure for the treatment of breast cancer and as a prophylactic procedure for those at high risk of developing the disease. However, it remains a controversial option due to questions regarding its oncological safety and concerns regarding locoregional recurrence. This systematic review with a pooled analysis examines the current literature regarding NSM, including locoregional recurrence and complication rates. Systematic electronic searches were conducted using the PubMed database and the Ovid database for studies reporting the indications for NSM and the subsequent outcomes. Studies between January 1970 and January 2015 (inclusive) were analysed if they met the inclusion criteria. Pooled descriptive statistics were performed. Seventy-three studies that met the inclusion criteria were included in the analysis, yielding 12,358 procedures. After a mean follow up of 38 months (range, 7.4–156 months), the overall pooled locoregional recurrence rate was 2.38%, the overall complication rate was 22.3%, and the overall incidence of nipple necrosis, either partial or total, was 5.9%. Significant heterogeneity was found among the published studies and patient selection was affected by tumour characteristics. We concluded that NSM appears to be an oncologically safe option for appropriately selected patients, with low rates of locoregional recurrence. For NSM to be performed, tumours should be peripherally located, smaller than 5 cm in diameter, located more than 2 cm away from the nipple margin, and human epidermal growth factor 2-negative. A separate histopathological examination of the subareolar tissue and exclusion of malignancy at this site is essential for safe oncological practice. Long-term follow-up studies and prospective cohort studies are required in order to determine the best reconstructive methods.

Abstract
BACKGROUND Since mastectomy remained the primary strategy for treating breast cancer in China, post-mastectomy reconstruction is of great importance in the Chinese population. The current study aimed to assess the current status of breast reconstruction in China. METHODS We reviewed all patients who received breast reconstruction from August 2000 to July 2015 in the Department of Breast Surgery in our institute. Patients' baseline characteristics, reconstruction strategy, final pathology and loco-regional recurrence (LRR) information were collected. RESULTS A total of 951 breast reconstructions were conducted during the past 15 years, among which 247 (27.0%) were abdominal flap reconstruction; 471 (51.5%) were latissimus dorsi myocutaneous ± implant; and 233 (25.5%) were prosthesis-based reconstruction. The majority of cases (78.1%) were invasive breast cancer and up to 894 cases (94.0%) were immediate reconstruction. Prosthesis-based reconstruction rapidly increased in recent years, and was associated with bilateral reconstruction, contralateral augmentation and higher complications. 18 patients (2.0%) developed local-regional recurrence at the median follow-up time of 26.6 months (range, 3.7-62.0 months). A total of 66 nipple-areolar complex-sparing mastectomies (NSMs) (6.9%) were performed, none of which developed recurrence. CONCLUSIONS Breast reconstruction cases increased over the 15 years with the change of paradigm. Most strikingly, prosthesis-based reconstruction rapidly gained its prevalence and became the most common strategy. NSM was only performed for highly selected patients. Patients with breast reconstruction were able to achieve satisfactory loco-regional control in our cohort.
