Orderable Test Description
HER2, a member of the epidermal growth factor receptor family, is a transmembrane protein with tyrosine kinase activity. Gene amplification and protein overexpression of HER2 have been found in a variety of tumors, including gastric/gastroesophageal adenocarcinoma. This test uses the Ventana PATHWAY anti-HER-2/neu antibody (clone 4B5) for the semi-quantitative detection of HER-2 antigen in sections of FFPE gastric/gastroesophageal adenocarcinoma. Staining is performed according to the package insert. Scoring for HER2 is performed according to 2016 CAP/ASCP/ACSO consensus guidelines for gastric/gastroesophageal adenocarcinoma.
