Abstract: | Recently, the association of Epstein-Barr virus (EBV) with undifferentiated lymphoepithelioma-like carcinoma and adenocarcinoma of the stomach has been described. In this study of 55 primary gastric lymphomas, most of them belonging to the group of MALT lymphomas, the question of possible EBV involvement has been addressed using in-situ hybridization (ISH) and blot techniques. EBV DNA and/or DNA sequences were found in only two of 24 centroblastic and B-immunoblastic lymphomas and in one anaplastic large cell lymphoma of null cell phenotype. In a further centroblastic lymphoma, a few positive nontumorous (bystander) cells were identified by ISH. |
