A neu view of invasive lobular breast cancer.
نویسنده
چکیده
Genome sequencing of relapsed, invasive lobular breast cancer identified actionable mutations in 86% of the cases. HER2 alterations occur in 27% of the cases, including 4 cases with activating HER2 mutations and 1 with a novel HER2-GRB7 gene fusion. This fusion links the HER2 tyrosine kinase domain to the GRB7 src homology 2 (SH2) domain.

Expression of E-cadherin and c-erbB-2/HER-2/neu oncoprotein in high-grade breast cancer.
E-cadherin (E-CD) is an epithelial-specific cell adhesion molecule, whose expression is lost in invasive lobular (ILC) but not in invasive ductal carcinoma (IDC) of the breast. This cell adhesion system can be disrupted by tyrosine kinase c-erbB-2/HER-2/neu. We examined 106 cases of high-grade invasive breast cancer, including 91 IDCs, 12 ILCs and 3 pleomorphic lobular carcinomas (PLCs). We det...
متن کاملImmunohistochemical detection of Her-2/neu overexpression in breast carcinoma in Nigerians: a 5-year retrospective study.
OBJECTIVE To determine the pattern of Her-2/neu status among breast carcinoma in the University of Benin Teaching Hospital, Benin City, Nigeria. MATERIALS AND METHODS Immunohistochemical staining for Her-2/neu was performed on 10% formalin-fixed, paraffin-embedded primary carcinoma of the breast from 83 patients, between 2003 and 2007 using anti-Her-2/neu rabbit polyclonal antibody (DakoCytom...
متن کاملPossible Prognostic Role of HER2/Neu in Ductal Carcinoma In Situ and Atypical Ductal Proliferative Lesions of the Breast.
HER2/neu is a well-established prognostic and predictive factor for invasive breast cancer. However, the role of HER2/neu in ductal breast carcinoma in situ (DCIS) is debated and recent data have suggested that it is mainly linked to in situ local recurrence. Although molecular data suggest that atypical ductal hyperplasia (ADH) and duct carcinoma in situ (DCIS) are related lesions, albeit with...
متن کاملImmunohistochemical expression of tissue inhibitor of metalloproteinase-1 (TIMP-1) in invasive breast carcinoma.
Tissue inhibitor of metalloproteinase-1 (TIMP-1) is a natural inhibitor of matrix metalloproteinases (MMPs). Aim of this study was to assess the immunohistochemical expression of TIMP-1 in invasive breast carcinomas, and to examine its association with classical clinico-pathological parameters, oestrogen receptor, progesterone receptor and Her-2/neu protein expression. Immunohistochemistry was ...

Background and purpose: Breast carcinoma is the most common malignant tumor and the leading cause of death due to cancer among women. Previous studies have shown that increased expression of dysadherin promotes cancer metastasis and reduced expression of E-cadherin was also associated with progression of epithelial tumors. The aim of this study was concurrent assessment of E- cadherin and dysad...
