Epstein-Barr virus (EBV) has been known to be associated with a wide variety of neoplastic conditions including nasopharyngeal carcinoma, Hodgkin's disease, and non-Hodgkin's lymphoma. Recent studies reveal the presence of EBV in certain subtypes of gastric carcinoma in which EBV appears to be pathogenetically related. To evaluate the relationship between EBV and gastric adenocarcinoma, we examined EBV DNA using direct in situ polymerase chain reaction, and expression of p53 protein and bcl-2 protein using immunohistochemical staining method on paraffin embedded tissues. The materials consisted of one hundred twenty-eight gastric adenocarcinomas and twenty benign peptic ulcers. EBV DNA was detected in 14 of 128 gastric adenocarcinomas (10.9%). p53 protein was positive in 10 of 14 EBV positive adenocarcinomas (71.4%) and in 61 of 114 EBV negative adenocarcinomas (53.5%). Bcl-2 protein was positive in 2 of 14 EBV positive adenocarcinomas (14.3%) and in 19 of 114 EBV negative adenocarcinomas (16.7%). The above results indicate that EBV is associated with gastric adenocarcinoma, and p53 protein may play a role in carcinogenesis of EBV in gastric adenocarcinoma.
