Background: Nipple-sparing mastectomy (NSM) is infrequently performed in older women, at least in part owing to concerns regarding age-related complications. We describe postoperative outcomes of NSM in older women and risk factors for complications, with the goal of informing patient selection and decision-making., Patients and Methods: Cases of NSM with immediate implant-based reconstruction were identified from an institutional database (2009-2019). Patient characteristics and postoperative complications were compared between women 45-54 years, 55-64 years, and  ≥ 65 years. Regression models were used to identify risk factors for serious complications and reconstruction failure., Results: Of 1998 NSMs in 1197 women, 1296 were in women 45-54 years, 521 in women 55-64 years, and 181 in women ≥ 65 years. Women ≥ 65 years had higher rates of comorbidities and more frequently incurred early postoperative complications (11% versus 7.3% in 55-64 years and 5.2% in 45-54 years, p = 0.005), particularly hematoma (5.0% versus 1.5% in 55-64 years and 1.2% in 45-54 years, p < 0.001). On univariate analysis, unadjusted rates of infection, necrosis, serious complications, and reconstruction failure did not differ significantly by age. Permanent reconstruction failure occurred in eight (4.4%) women ≥ 65 years. On multivariable analysis, age was not an independent predictor of serious complications or reconstruction failure, though current smoking, in addition to factors more common in older women (diabetes, hypertension, anticoagulation, prior radiotherapy), emerged as independent risk factors., Conclusions: After adjusting for patient factors, older age did not increase risk of complications after NSM. Studies on functional and quality-of-life outcomes may help further refine patient selection and facilitate decision-making., Competing Interests: Disclosure: The authors have nothing to disclose., (© 2025.

Background: Nipple-sparing mastectomy (NSM) is an oncologically safe approach for breast cancer treatment and prevention; however, there are little long-term data to guide management for patients whose nipple margins contain tumor or atypia., Methods: NSM patients with tumor or atypia in their nipple margin were identified from a prospectively maintained, single-institution database of consecutive NSMs. Patient and tumor characteristics, treatment, recurrence, and survival data were assessed., Results: A total of 3158 NSMs were performed from June 2007 to August 2019. Nipple margins contained tumor in 117 (3.7%) NSMs and atypia only in 164 (5.2%) NSMs. Among 117 nipple margins that contained tumor, 34 (29%) margins contained invasive cancer, 80 (68%) contained ductal carcinoma in situ only, and 3 (3%) contained lymphatic vessel invasion only. Management included nipple-only excision in 67 (57%) breasts, nipple-areola complex excision in 35 (30%) breasts, and no excision in 15 (13%) breasts. Only 23 (24%) excised nipples contained residual tumor. At 67 months median follow-up, there were 2 (1.8%) recurrences in areolar or peri-areolar skin, both in patients with nipple-only excision. Among 164 nipple margins containing only atypia, 154 (94%) nipples were retained. At 60 months median follow-up, no patient with atypia alone had a nipple or areola recurrence., Conclusions: Nipple excision is effective management for nipple margins containing tumor. No intervention is required for nipple margins containing only atypia. Our results support broad eligibility for NSM with careful nipple margin assessment., (© 2024. Society of Surgical Oncology.)

Introduction: Oncoplastic breast surgery (OBS) combines plastic surgery techniques with conventional breast-conserving surgery (BCS) and expands BCS eligibility. Limited data are available on patient-reported outcomes (PROs) after OBS. Here we compare long-term PROs after OBS and BCS utilizing the BREAST-Q., Patients and Methods: Women undergoing OBS or BCS between 2006 and 2019 who completed ≥ 1 long-term BREAST-Q survey 3-5 years postoperatively were identified. Baseline characteristics were compared between women who underwent OBS/BCS. Women who underwent OBS were paired with those who underwent BCS using 1:2 propensity matching [by age, body mass index (BMI), race, T stage, and multifocality]. BREAST-Q scores were compared preoperatively and 3-5 years postoperatively., Results: A total of 297 patients were included for analysis (99 OBS/198 BCS). Women who underwent OBS were younger (p < 0.001) and had higher BMI (p = 0.005) and multifocal disease incidence (p = 0.004). There was no difference between groups in nodal stage, re-excision rates, axillary surgery, chemotherapy, endocrine therapy, or radiotherapy. After propensity matching preoperatively, women who underwent OBS reported lower psychosocial well-being (63 versus 100, p = 0.039) but similar breast satisfaction and sexual well-being compared with women who underwent BCS; however, only three patients who underwent BCS had preoperative BREAST-Q scores available for review. In long-term follow-up, women who underwent OBS reported lower psychosocial scores (74 versus 93, p = 0.011) 4 years postoperatively, but not at 5 years (76 versus 77, p = 0.83). There was no difference in long-term breast satisfaction or sexual well-being., Conclusions: Women who undergo OBS present with a larger disease burden and may represent a group of non-traditional BCS candidates; they reported similar long-term breast satisfaction and sexual well-being compared with women who undergo BCS. While women who underwent OBS reported lower psychosocial well-being scores preoperatively and during a portion of the follow-up period, this difference was no longer seen at 5 years postoperatively., (© 2023.

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., (© 2023. Society of Surgical Oncology.)

Background: Younger women (age ≤ 40 years) with breast cancer undergoing neoadjuvant chemotherapy (NAC) have higher rates of pathologic complete response (pCR); however, it is unknown whether axillary or breast downstaging rates differ by age. In this study, we compared pCR incidence and surgical downstaging rates of the breast and axilla post NAC, between patients aged ≤ 40, 41-60, and ≥ 61 years., Methods: We identified 1383 women with stage I-III breast cancer treated with NAC and subsequent surgery from November 2013 to December 2018. pCR and breast/axillary downstaging rates were assessed and compared across age groups., Results: Younger women were significantly more likely to have ductal histology, poorly differentiated tumors, and BRCA mutations; 35% of tumors were hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-), 36% were HER2-positive (HER2+), and 29% were triple negative (TN), with similar subtype distribution across age groups (p = 0.6). Overall, pCR rates did not differ by age, however among patients with TN tumors (n = 394), younger women had higher pCR rates (52% vs. 35% among those aged 41-60 years and 29% among those aged ≥61 years; p = 0.007) and were more likely to have tumors with high tumor-infiltrating lymphocyte (TIL) concentrations (p < 0.001). Downstaging to breast-conserving surgery (BCS) eligibility post NAC among initially BCS-ineligible patients was similar across age groups; younger women chose BCS less often (p < 0.001). Among cN1 patients (n = 813), 52% of women ≤40 years of age avoided axillary lymph node dissection (ALND) with NAC, versus 39% and 37% in the older groups (p < 0.001)., Conclusions: Younger women undergoing NAC for axillary downstaging were more likely to avoid ALND across all subtypes; however, overall pCR rates did not differ by age. Despite equivalent breast downstaging and BCS eligibility rates across age groups, younger women were less likely to undergo BCS., (© 2022. Society of Surgical Oncology.)

Introduction: Venous thromboembolism (VTE) is a significant cause of morbidity and mortality after bariatric surgery. Roughly 80% of VTEs occur post-discharge. The frequency of post-discharge heparin (PDH) prophylaxis use is unknown, and evidence about benefits and risks is limited. We aimed to determine the rate of use of PDH prophylaxis and evaluate its relationship with VTE and bleeding events., Methods: Using the Truven Health MarketScan® database, we performed a retrospective cohort study (2007-2015) of adult patients who underwent sleeve gastrectomy or gastric bypass. We determined PDH prophylaxis from outpatient pharmacy claims, and post-discharge 90-day VTE and bleeding events from outpatient and inpatient claims. We used propensity score-adjusted regression models to mitigate confounding bias., Results: Among 43,493 patients (median age 45 years; 78% women; 77% laparoscopic gastric bypass, 17% laparoscopic sleeve gastrectomy, 6% open gastric bypass), 6% received PDH prophylaxis. Overall, 224 patients (0.52%) experienced VTEs, and 806 patients (1.85%) experienced bleeding. The unadjusted VTE rate did not differ between patients who did and did not receive PDH prophylaxis (0.39% vs. 0.52%, respectively; p = 0.347). The unadjusted bleeding rate was higher for the PDH prophylaxis group (2.74% vs. 1.80%, p < 0.001). In our adjusted analysis, a 23% lower risk of VTE in the PDH prophylaxis group was not statistically significant (odds ratio [OR] 0.77, 95% confidence interval [CI] 0.41 to 1.46), whereas the 47% higher risk of bleeding was statistically significant (OR 1.47, 95% CI 1.14 to 1.88)., Conclusions: PDH prophylaxis after bariatric surgery is uncommon. In our analysis, use was not associated with a lower VTE risk but was associated with a higher bleeding risk., (© 2020. Springer Science+Business Media, LLC, part of Springer Nature.)
