HER-2/neu diagnostics in breast cancer
HER-2/neu status of the primary breast cancer (PBC) is determined by immunohistochemistry and fluorescent in situ hybridization. Because of a variety of technical factors, however, the PBC may not accurately reflect the metastatic tumor in terms of HER-2/neu status. Recently published guidelines recommend that tumors be defined as HER-2/neu positive if 30% or more of the cells are 3+. Circulati...
متن کاملHER-2 Signaling in Human Breast Cancer
1.1 erbB family HER-2 is a member of the erbB family of receptor tyrosine kinases. Epidermal Growth Factor Receptor (EGFR) was first identified as the cellular homolog of the transduced oncogene of the avian retroviruses such as avian ERythroBlastosis virus, which causes erythroleukemia and fibrosarcoma and gives rise to the family name (erbB). EGFR, as its name implies, was shown by Stanley Co...
متن کاملHER-2-positive metastatic breast cancer: optimizing trastuzumab-based therapy.
Trastuzumab with a taxane as first-line therapy is now the standard of care for patients with human epidermal growth factor receptor 2 (HER-2)-positive metastatic breast cancer (MBC). The search for additional and more effective trastuzumab-based therapies continues. Novel combinations of trastuzumab with chemotherapeutic agents, including vinorelbine, gemcitabine, and capecitabine, and hormona...
متن کاملHER-3 expression in HER-2-amplified breast carcinoma
AIM OF THE STUDY To determine whether the expression of HER-3 influences the survival of HER-2 positive patients with breast cancer (BC). MATERIAL AND METHODS In the present work, the expression of HER-3 in a group of 35 HER-2 positive patients with BC was studied by performing immunohistochemistry (IHC) in formalin-fixed paraffin embedded tissues. RESULTS Higher HER-3 status if estimated b...
متن کاملHER-2 gene amplification in human breast cancer without concurrent HER-2 over-expression
BACKGROUND Testing for human epidermal growth factor receptor-2 (HER-2) in breast cancer is performed by either immunohistochemistry (IHC) or in situ hybridization (ISH). The growth factor receptor-bound protein-7 (GRB7) gene is in close proximity to HER-2 on chromosome 17q11-12 and codes a signal transduction molecule shown to be an independent adverse marker in breast cancer. METHODS HER-2 ...
