, , , , , , , In this study, we compared indications and outcomes of 115 young (< 40 years) versus 40 elderly (> 60 years) patients undergoing nipple-sparing mastectomy (NSM) as risk-reducing surgery or for breast cancer (BC) treatment.
Between January 2004 and December 2018, young and elderly patients undergoing NSM with complete data from at least 6 months of follow-up were included.
BC treatment was the main indication for NSM, observed in 85(73.9%) young versus 33(82.5%) elderly patients, followed by risk-reducing surgery in 30(26.1%) young versus 7(17.5%) elderly patients. Complication rates did not differ between the age groups. At a median follow-up of 43 months, the overall recurrence rate was higher in the younger cohort (p = 0.04). However, when stratified into local, locoregional, contralateral, and distant metastasis, no statistical difference was observed. During the follow-up, only 2(1.7%) young patients died.
Our findings elucidate a higher recurrence rate of breast cancer in younger patients undergoing NSM, which may correlate with the fact that age is an independent prognostic factor. High overall survival and low complication rates were evidenced in the two groups showing the safety of NSM for young and elderly patients.

, , , , , , , Breast cancer (BC) biomarkers, such as hormone receptors expression, are crucial to guide therapy in BC patients. Antiandrogens have been studied in BC; however, limited data are available on androgen receptor (AR) expression test methodology. We aim to report the core needle biopsy (CNB) accuracy for AR expression in BC.
Patients diagnosed with stage I-III invasive BC from a single institution were included. Androgen receptor expression was evaluated by immunohistochemistry (IHC) using 1 and 10% cutoff and the AR expression in surgical specimens (SS) was the gold standard. Kappa coefficients were used to evaluate the intraprocedural agreement.
A total of 72 patients were included, with a mean age of 61 years old and 84% were Luminal A or B tumors. The prevalence of AR expression in all BC samples was 87.5% using a cutoff ≥ 10% in SS. With a cutoff value ≥ 1%, CNB had an accuracy of 95.8% (Kappa value = 0.645; 95% confidence interval [CI]: 0.272–1.000; p < 0.001) and 86.1% (Kappa value = 0.365; 95% CI: 0.052–0.679; p < 0.001) when ≥ 10% cutoff was used for AR positivity. Androgen receptor expression in CNB (cutoff ≥ 1%) had a sensitivity of 98.5%, specificity of 60%, positive predictive value of 97.0%, and a negative predictive value of 76.9% in the detection of AR expression in SS.
Core needle biopsy has good accuracy in evaluating AR expression in BC. The accuracy of CNB decreases with higher cutoff values for AR positivity.

, , , , , , , 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.
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.
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 60months, the local recurrence rate was of 8.9%, the disease-free survival rate was of 90%, and 1 of the patients died.
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.

, , , , , , , , Few studies analyzed the safety of salvage nipple-sparing mastectomy (NSM) for local relapse treatment. We evaluated the outcomes of patients with indications for mastectomy who chose to undergo NSM for ipsilateral breast tumor recurrence (IBTR).
Between January 2001 and December 2018, we evaluated 24 women who underwent NSM for local relapse after conservative surgery.
Thepatientswere followedupfor amean time of132months since thefirst surgery. After the NSM, 5 (20.8%) patients were diagnosed with local recurrence and only 1 (4.2%) patient died. The patients presented 4.8% (2) of partial and 2.4% (1) of total nipple necrosis.
In this long-term follow-up since the first surgery, we observed low rates of complication and good survival, although associated with high local recurrence in patients diagnosed with IBTR undergoing NSM as salvage surgery.We demonstrated that NSMmay be considered after IBTR for patients who did not want to undergo total mastectomy.
