Background: Accurate HER2 status is crucial for gastric adenocarcinoma (GC) patient selection for antiHER2 therapy. It is assessed immunohistochemically (IHC) for protein expression, and by silver in-situ hybridization (SISH) for gene copy number. Th

Human epidermal growth factor receptor 2 (HER2) status determines gastric/gastroesophageal junction (GEJ) adenocarcinomas that benefit from targeted therapy; hence, HER2 testing has become a routine practice. Accurate HER2 testing is fundamental to s
