Axillary reverse mapping (ARM) is a new technique developed with the aim of reducing lymphedema rates by preserving lymphatic drainage of the upper limbs during sentinel lymph node biopsy and axillary lymph node dissection (ALND). However, it is unclear whether preservation of these lymph nodes affects oncological risk. The present study evaluated the(More)
INTRODUCTION In this prospective ex vivo study, we propose a new technique for the intraoperative examination of retroareolar tissue and describe both surgical excision and pathological methods. We performed a nipple-sparing mastectomy simulation in patients selected to total mastectomy, in order to evaluate the accuracy of these new technique. MATERIALS(More)
Gastrointestinal metastases from breast cancer are rare and generally occur several years after the diagnosis of the primary lesion. The diagnosis of gastric metastasis as the initial presentation of breast cancer is even rarer and can potentially mimic gastric carcinoma. We report the case of a 66-year-old female patient submitted to a total gastrectomy(More)
PURPOSE To estimate the likelihood of axillary lymph node involvement for patients with early-stage breast cancer, based on a variety of clinical and pathological factors. METHODS A retrospective analysis was done in hospital databases from 1999 to 2007. Two hundred thirty-nine patients were diagnosed with early-stage breast cancer. Predictive factors,(More)
Introduction Neoadjuvant chemotherapy (NAC) is the standard treatment for locally advanced breast cancer. However, some tumors will not respond to this treatment due to histological and molecular features. The protein EZH2 (enhancer of zest homolog 2) is a histone methyltransferase that is correlated with poorly differentiated breast carcinomas and(More)
OBJECTIVE The objective of this study was to determine the impact of the use of single-photon emission computed tomography fused with computed tomography (SPECT-CT) on thoracoscopic biopsy of sentinel lymph nodes (SLNs) in the internal mammary chain in patients with breast cancer by evaluating resultant changes in staging and their clinical implications.

CONTEXT Surgery is the main form of treatment for ductal carcinoma in situ (DCIS) of the breast. Among other factors, treatment success requires that the surgical margins are free of disease, to reduce the risk of recurrence. AIMS The purpose of this study was to analyze factors that might be associated with positive margins in patients diagnosed with(More)
