BACKGROUND: E-cadherin and vimentin are regarded as major conventional canonical markers of the epithelial-mesenchymal transition. It is commonly assumed that E-cadherin is uniformly lost during the process of epithelial-mesenchymal transition. Breast tumor cells typically invade as a cohesive multicellular unit in a process called collective invasion. The aim of this study was to reveal the clinical importance of the expression pattern of E-cadherin and vimentin in breast cancer. METHODS: E-cadherin and vimentin protein expression was evaluated by immunohistochemistry in 176 invasive breast cancer samples...

BACKGROUND: Recently there are efforts to use sentinel lymph node biopsy (SLNB) techniques after neoadjuvant chemotherapy (NAC) to minimize axillary surgery. However, studies have shown higher false negative rates in this scenario, which might result in inaccurate assessment of treatment response and patient prognosis as well as leaving residual disease behind. In this study, we describe the use of reflector-guided excision of the percutaneously biopsied node (PBN) as an aid to conventional SLNB and its predictor of the axillary status after NAC...

Trastuzumab improves survival outcomes for patients with HER2-positive (HER2+ ) breast cancer, yet not all such women receive this important therapy. Trastuzumab was approved by the US Food and Drug Administration in 1998 and the European Medicines Agency in 2000 as treatment for HER2+ metastatic breast cancer (MBC). Observational studies between 2000 and 2015 in patients with HER2+ MBC suggest that nearly 12% in the United States, 27% to 54% in Europe, and 27.1% to 49.2% in China did not receive trastuzumab or any other HER2-targeted agent as first- and/or later-line for treatment of metastatic disease...

BACKGROUND: Caveolae play a role in cell signal transduction, kinetic regulation of transport vesicles, and cellular physiology. In this study, we evaluated the role of caveolin-1 (CAV-1) genotypes in the risk of breast cancer. PATIENTS AND METHODS: We evaluated 6 single nucleotide polymorphisms of the CAV-1 gene in a sample size of 406 participants. Six polymorphisms-G32124A (rs3807992), T29107A (rs7804372), T28608A (rs3757733), G21985A (rs12672038), G14713A (rs3807987), and C521A (rs1997623)-were assessed using restriction fragment length polymorphism polymerase chain reaction...

INTRODUCTION: The murine double minute 4 (MDM4) protein is a negative regulator of p53, and its upregulation has been observed in many tumor types. Previous literature suggested that genetic variations in the MDM4 gene are associated with risk of different cancers. The objective of the present study was to examine the effect of 3 common genetic variants of MDM4, rs4245739 A>C, rs11801299 G>A, and rs1380576 C>G, on the risk of breast cancer (BC) in a southeast Iranian population sample...

Breast cancer patients who present with nodal metastasis receive neoadjuvant chemotherapy (NAC) with increasing frequency and can have complete pathologic response after treatment. In this clinical scenario, sentinel node mapping and biopsy are gaining acceptance instead of axillary dissection to avoid morbidity. Biopsy proven positive lymph nodes must be reliably excised and examined after NAC to further decrease the false negativity rate of sentinel lymph node (SLN) surgery. The standard method for axillary staging in breast cancer patients even after NAC is SLN biopsy (SLNB) with a radioisotope, blue dye, or both (dual technique)...

BACKGROUND: Although several studies have shown efficacy of nanoparticle albumin-bound (nab) paclitaxel use as a neoadjuvant treatment in breast cancer, dosage and schedules were varied or used in combination and the data are still limited for weekly regimens. We evaluated the feasibility of weekly nab-paclitaxel followed by FEC (5-FU [fluorouracil], epirubicin, and cyclophosphamide) treatment feasibility as neoadjuvant chemotherapy for breast cancer. PATIENTS AND METHODS: Thirty-three patients with no previous chemotherapy were enrolled to receive nab-paclitaxel 150 mg/m 2 the first 3 of 4 weeks (3q4w) followed by FEC as neoadjuvant treatment...

With breast cancer screening programs becoming more available worldwide and covering larger age ranges, the prevalence of impalpable breast pathology is increasing. Whilst there is a 'tried and tested' technique for localizing occult lesions, the market for alternative methods is increasing and is estimated to pass $1 billion by 2024. In this article, we review the techniques currently available for localization of occult breast lesions and discuss the pros and cons of each.

We have performed a narrative synthesis. A literature search was conducted between January 2000 and June 2014 in 7 databases. The initial search identified 2717 articles; 319 underwent abstract screening, 67 underwent full-text screening, and 25 final articles were included. This review looked at early stage breast cancer in women only, excluding ductal carcinoma in situ and advanced breast cancer. A conceptual framework was created to organize the central constructs underlying women's choices: clinicopathologic factors, physician factors, and individual factors with subgroups of sociodemographic, geographic, and personal beliefs and preferences...

INTRODUCTION: The L1 cell adhesion molecule (L1-CAM) and its soluble form sL1 play a prominent role in invasion and metastasis in several cancers. However, its association with breast cancer is still unclear. PATIENTS AND METHODS: We analyzed L1-CAM expression and serum sL1 levels in cancer and para-carcinoma tissues from 162 consecutive patients with primary invasive breast cancer (PBC) using immunohistochemistry and an enzyme-linked immunosorbent assay, respectively...

INTRODUCTION: Adherence to aromatase inhibitor (AI) therapy is poor, often because of treatment-emergent side effects, including musculoskeletal symptoms, fatigue, and insomnia. In the present analysis, we examined the sleep patterns and daytime function both objectively using actigraphy and subjectively using validated questionnaires in women initiating AI therapy. PATIENTS AND METHODS: Postmenopausal women with stage 0-III hormone receptor-positive breast cancer who were initiating AI therapy were eligible...

BACKGROUND: Although brain metastases (BM) are associated with poor prognosis, patients with human epidermal growth factor receptor 2 (HER2) overexpressing (HER2+ ) breast cancer (BC) with BM who are treated with anti-HER2 therapy have a relatively longer survival after BM diagnosis compared with other subtypes and HER2+ patients previously untreated with anti-HER2 therapy. It is unclear if previously reported prognostic factors are applicable to patients with HER2+ BC in the era of HER2-targeted therapy...
