Background and purpose: Gastric carcinoma is the second leading cause of cancer death worldwide and its incidence varies considerably according to geographical location. There are multiple etiologic factors such as infection with �BV that play a role in carcinogenesis of gastric cancer, yet there is not enough evidence about pathogenesis of �BV and its relationship with gastric cancer. Thus, recognizing pathogenic genes can help improve the prognosis of the patients. The purpose of this study is to explore the relationship between �BV and �BV-encoded B�RF-1 oncogene in gastric adenocarcinoma pathogenesis. Materials and methods: �n this analytical case-control study, 200 paraffin-embedded blocks of biopsies of patients with gastric cancer and those of healthy people were selected. �fter DN� extraction, polymerase chain reaction (P�R) was used to determine �BV genome and B�RF-1 oncogene by specific primers of B�RF-1. Grade and stage of the gastric cancer biopsies were also examined. Results: The results of P�R indicated that �BV genome was detected in three cases in the case group, whereas all samples in the control group were negative for �BV. Thus, no significant relationship was observed between the two groups (P>0.05). The �BV positive gastric cancers were negative for B�RF-1 oncogene. �t was also found that 41 of the cancers were grade �, 52 grade ��, and 7 grade ���. �onclusion: The findings suggest that gastric cancer has a high prevalence in the geographical region under study however, �BV plays a minor role in the carcinogenesis of gastric adenocarcinoma.
