Human Epidermal Growth Factor Receptor-2(HER-2) expression in Sri Lankan gastric adenocarcinoma patients: An analysis of the concordance of HER2 expression and survival based on silver in-situ hybridization (SISH)
Abstract: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. This study aimed to evaluate the concordance of HER2 status by IHC/SISH analyses and HER2-SISH based survival.Methods: This prospective study includes 145 GC’s (excluding gastro-oesophageal-junction tumours) from the National Hospital of Sri Lanka with defined demogr… Show more
