Introduction: Tissue rearrangement after an oncoplastic breast reduction may complicate identification of margins during reexcision. Little is known about outcomes of reoperation in this setting. Methods: This is a single-institution, retrospective analysis of outcomes of margin reexcisions after lumpectomy with concurrent oncoplastic Wise-pattern reduction from 2015 to 2020. Outcomes assessed were the rate of successful breast conservation, in-breast recurrence, wound issues or complications, effect on cosmesis, and delay to onset of adjuvant therapy. Results: From 2015 to 2020, 649 patients underwent lumpectomy with oncoplastic Wise-pattern reduction. Forty-seven patients (7.2%) had greater than or equal to one positive margin(s); of these, 28 went directly to mastectomy, and 19 underwent margin reexcision. Residual disease was found in seven of 19 patients (37%) at reexcision. The rate of successful breast-conserving therapy was 95% with a mean follow-up of 31 months. There was one (5%) in-breast recurrence (invasive ductal carcinoma [IDC] occurring 30 months after the original operation); this patient had a mastectomy for treatment of her recurrence. The overall complication rate was 37%. Radiation was administered to 18 patients (95%), and two patients (11%) had delay of radiation past 6 weeks due to wound complications. Of the 14 patients with photographs available, 12 of 14 patients (86%) were blindly assessed to have equivalent or better cosmesis after margin reexcision (versus initial lumpectomy). Conclusion: Margin reexcision after oncoplastic breast reduction with Wise-pattern is feasible and effective, and can be done without compromising the initial cosmetic results.

Background Recently, several invasive meningococcal disease (IMD) outbreaks caused by Neisseria meningitidis have occurred among people experiencing homelessness (PEH). However, overall IMD risk among PEH is not well described. We compared incidence and characteristics of IMD among PEH and persons not known to be experiencing homelessness (non-PEH) in the United States. Methods We analyzed 2016–2019 IMD data from the National Notifiable Diseases Surveillance System (NNDSS) and enhanced meningococcal disease surveillance. Incidence was calculated using U.S. census data and Point-in-Time counts from the U.S. Department of Housing and Urban Development. Results Of cases from states participating in enhanced surveillance during 2016–2019 (n = 1409), 45 (3.2%) cases occurred among PEH. Annual incidence was higher among PEH (2.12 cases/100,000) than non-PEH (0.11 cases/100,000; relative risk: 19.8, 95% CI: 14.8–26.7). Excluding outbreak-associated cases (PEH n = 18, 40%; non-PEH n = 98, 7.2%), incidence among PEH remained elevated compared to incidence in non-PEH (relative risk: 12.8, 95% CI: 8.8–18.8). Serogroup C was identified in 68.2% of PEH cases compared to 26.4% in non-PEH (p < 0.0001). Conclusions PEH are at increased risk for IMD. Further assessment is needed to determine the feasibility and potential impact of meningococcal vaccination for PEH in the United States.

Background: For patients with large and/or ptotic breasts, a planned staged approach to nipple-sparing mastectomy (NSM) has been described. Less is known about surgical outcomes of unplanned staged NSM for management of positive margins after partial mastectomy with oncoplastic reduction. It is not clear from earlier studies whether an interval of less than 10 weeks between oncoplastic reduction and NSM is feasible, when a shorter interval is important for oncologic reasons. Methods: This is a single institution analysis of patients from 2018 to 2021 with a diagnosis of invasive cancer or ductal carcinoma in situ who underwent NSM after oncoplastic breast reduction for positive margins or nodes. The primary endpoint measured was nipple loss. Secondary outcomes were need for operative re-intervention and wound complications. Results: Nine patients (14 breasts) underwent partial mastectomy with oncoplastic Wise-pattern breast reduction, followed by NSM. Three patients underwent intersurgery chemotherapy. The average interval between oncoplastic reduction and NSM was 11.3 weeks when excluding patients undergoing chemotherapy (range 8-13 weeks). Thirteen breasts (93%) underwent pre-pectoral direct-to-implant reconstruction. One breast (7%) received autologous reconstruction. One breast required reoperation for seroma. The rate of partial or total nipple loss was 0%, with an average follow-up of 1.6 years. Conclusions: Our experience demonstrates excellent outcomes from NSM after oncoplastic breast reduction, with the majority of patients undergoing single-stage pectoral direct-to-implant breast reconstruction. Overall, patients had a shorter intersurgery interval, compared with prior studies, with no cases of nipple loss. An intersurgery interval of 8 weeks may be feasible when avoiding delays is important for oncologic reasons.
