The infectious agents may be the etiological factor of up to 15-20% of cancers. In stomach cancer, attention is paid to Helicobacter pylori and Epstein-Barr virus, both of which cause gastritis and can lead to tumor development. In co-infection, the inflammatory process is much more intense. We assessed the seroprevalence towards H. pylori and EBV in 32 patients with diagnosed gastric cancer. H. pylori antibodies were found in 69% patients, and anti-EBV - in all of them. The study confirmed that co-infection of H. pylori and EBV seems to be important in etiopathology of gastric cancer.
Keywords: EBV; Helicobacter pylori prevalence; co-infection; gastric cancer; infection agents in cancer.
