Non-detection of Epstein-Barr virus and human papillomavirus in a region of high gastric cancer risk indicates a lack of a role for these viruses in gastric carcinomas

Abstract

Gastric mucosa tissue was collected from patients with gastroduodenal diseases in a region of norrteastern China showing a high risk of gastric cancer incidence. The presence of EBV and HPV were assayed to investigate the relationship between gastric carcinomas and virus infection. Neither EBV nor HPV DNA was detected in tissue from the patients. The role of EBV and HPV in gastric cancer is not well understood and still needs to be clarified.
