Epstein-barr virus infection closely associated with the occurrence and development of gastric cancer. Epsteinbarr virus-associated gastric carcinomas accounted for about 8.2% of all gastric cancers, in which EBER positive in cancer cell nucleus was confirmed by the in situ hybridization (ISH). In 2014 according to the molecular phenotype, TCGA divided gastric carcinomas into four subtypes: EBV-positive; microsatellite instability (MSI); genomically stable (GS) and chromosomally instability (CIN), which opened the new era of targeted therapies in the gastric carcinomas. Based on the uniqueness of its biological behavior, this paper reviewed the research advances about the epidemiology, clinical manifestation, histopathologic features, pathogenesis, treatment and prognosis of EBV-associated gastric cancers.
