Epstein Barr Virus (EBV) is responsible of 10% of Gastric Cancer (GC), correlating with better survival rates. In Peru, there were not studies about prevalence and clinical characteristics of CG EBV positive. Objective: Determine prevalence and clinicopathological characteristics of GC EBV positive. Materials and methods: 111 GC tumour samples were centrally screened by Chromogenic in situ hybridization (CISH) technique for EBV-encoded RNA (EBER) transcript. Results: 8.4% of cases were positive for EBV. Most cases EBV positive were more than 60 years old; male, antrum/pylorus had more frequent localizations. Most cases had an intestinal type and tubular patter and a tendency to better prognostic in comparison EBV negative cases.
