This study aimed to explore the optimal time of sentinel lymph node biopsy (SLNB) and neo-adjuvant chemotherapy (NAC) and to assess the feasibility of selective elimination of axillary surgery after NAC in clinically node-negative (cN0) patients. From April 2010 to August 2018, 845 patients undergoing surgery after NAC were included in this retrospective study to analyze the correlation between different clinicopathological characteristics of cN0 patients and negative axillary lymph node after NAC (ypN0). Among the 148 cN0 patients, 83.1% (123/148) were ypN0. ⋯ Molecular subtypes (OR = 2.374, P = 0.033), clinical stage (OR = 0.320, P = 0.029), and bpCR (OR = 0.454, P = 0.012) were independent predictors for ypN0. The optimal time of SLNB and NAC in cN0 patients might be different among different molecular subtypes: it would be preferable to perform SLNB prior to NAC for HR+/HER2- patients, and SLNB after NAC for TN and HER2+ patients to reduce the risk of axillary lymph node dissection. In view of the high ypN0 rate in cN0 patients, axillary surgical staging might be selectively eliminated, especially for HER2+ and TN patients.

Nipple-sparing mastectomy (NSM) with immediate implant-based reconstruction has better esthetic outcomes and improved patient satisfaction, in addition to being oncologically safe. A known complication of NSM is skin flap necrosis. The use of tumescence and sharp dissection may decrease this complication compared to the standard NSM technique using electrocautery. ⋯ The operative time was significantly shorter in the sharp dissection group with the mean (SD) time being 183.5 (48.9) minutes compared to the standard electrocautery group at 202.9 (33.8) minutes (P = 0.03). NSM using tumescence and sharp dissection have a lower rate of the complications of partial- and full-thickness necrosis. Shorter operative time was also seen with the tumescent technique.

Several endocrine-based therapies have recently been evaluated as treatments for premenopausal women with hormone-receptor-positive/human-epidermal-growth-factor-receptor 2 negative (HR+/HER2-) metastatic breast cancer (mBC). We conducted a systematic review and assessed the feasibility of an indirect treatment comparison (ITC) to characterize the comparative efficacy of endocrine-based therapies in this setting. A systematic literature review (SLR) of Medline, EMBASE, Cochrane Library and key conferences was performed to identify randomized clinical trials (RCTs) satisfying the following criteria: (a) included pre/perimenopausal women with HR+/HER2- mBC, (b) included endocrine-based therapies, (c) reported efficacy, safety, or quality of life outcomes, and (d) was published in 2007 or later (when HER2 testing was standardized). ⋯ Therefore, we were not able to characterize the relative efficacy of the different endocrine-based therapies available in the premenopausal HR+/HER2- mBC setting. This systematic review provides a comprehensive assessment of the available trial evidence on the efficacy and safety of endocrine-based therapies for premenopausal women with HR+/HER2- mBC. Only four trials have reported relevant data in this setting, and MONALEESA-7 is currently the only trial focused on premenopausal HR+ HER2- mBC in the first-line setting.

Axillary nodal status remains an important determinant of prognosis and of the therapeutic strategy in patients with a newly diagnosed breast cancer. The aim of this study was to assess the false-negative rate of ultrasound (US)-guided fine-needle aspiration cytology (FNAC) in axillary node staging at breast cancer diagnosis. All patients with a newly diagnosed breast cancer who had an indeterminate or suspicious axillary node sampled with an FNAC between 2007 and 2014 were included in the study. ⋯ Of the 351 patients with benign FNAC (C2), 31% (n = 108) of patients had a positive lymph node on histology. The false-negative rate of preoperative FNAC remains too high (31%) to omit definitive surgical staging of the axilla. The high diagnostic accuracy when a positive FNAC is obtained allows appropriate tailored decisions regarding definitive therapy.
