Background and Aim: The accurate determination of HER-2 in invasive breast cancer has become a critical issue, particularly in context of the results of Herceptin adjuvant therapy. The aim of this study was to evaluate inter- and intraobserver reproducibility of assessment of HER2/neu immunostaining in invasive breast cancerMaterials and Methods: This study was cross sectional and the conve...
OBJECTIVE The aim of this study was to explore the expression of DLC-l in breast carcinoma and any association with tumor metastasis. METHODS 51 surgical specimens of human breast carcinoma, divided into high invasive and low invasive groups according to their clinicopathological features, 30 cases of adjacent normal tissue and 28 benign breast lesions were examined by qRT-PCR for expression ...
Invasive ductal carcinoma NOS, or no special type, is the most common type of breast cancer representing 65% to 75% of mammary carcinomas (1,2). Depending on the size of the lesion, size of the breast, and proximity of the lesion to the skin, patients can present with a hard, fixed, palpable mass that may cause skin thickening and retraction (Fig. 8.1). If the cancer is in the subareolar area, ...
Background. To our knowledge, the hormone receptor status of noncontiguous ductal carcinoma in situ (DCIS) occurring concurrently in ER/PgR-negative invasive cancer has not been studied. The current study was undertaken to investigate the ER/PgR receptor status of DCIS of the breast in patients with ER/PgR-negative invasive breast cancer. Methods. We reviewed the immunohistochemical (IHC) stain...
PURPOSE BNIP3 is involved in cell death and cell survival via autophagy. Its perinecrotic localization within ductal carcinoma in situ (DCIS) suggests an involvement in neoplastic cellular adaptation to low oxygen tension. This study has investigated the role of BNIP3 in normal and neoplastic breast. EXPERIMENTAL DESIGN Whole sections from 11 normal breast and microarrayed tissue cores from 8...
Background: Breast Cancer in the Middle East and North Africa region (MENA) occurs in a younger age group of patients and is more aggressive than in Europe and North America. Little is known about the presence of immune infiltration and clinico-pathologic correlates in patients from the MENA region. Immune infiltration of most solid tumors carries a prognostic role. Adaptive immune cells and cy...
EGF-like module containing mucin-like hormone receptor 2 (EMR2) is a leukocyte-restricted adhesion G protein-coupled receptor. Aberrant expression of EMR2 and its highly homologous molecule CD97 have been reported in various human cancers. Herein, we investigate the expression of EMR2 in neoplastic breast human tissue and its relationship with patient survival. EMR2 expression in normal and neo...
PURPOSE Breast cancers can display distinct clinical characteristics in different ethnic populations. Previous studies involving European and United States patients have shown that breast tumors can be divided by their gene expression profiles into distinct "molecular subtypes." In this report, we surveyed a series of invasive and preinvasive breast tumors from Asian-Chinese patients to investi...
Expression of AMAP1, an ArfGAP, provides novel targets to inhibit breast cancer invasive activities.
Identification of the molecular machinery employed in cancer invasion, but not in normal adult cells, will greatly contribute to cancer therapeutics. Here we found that an ArfGAP, AMAP1/PAG2, is expressed at high levels in highly invasive breast cancer cells, but at very low levels in noninvasive breast cancer cells and normal mammary epithelial cells. siRNA-mediated silencing of AMAP1 effectiv...
