Gastric cancer is a significant health problem in Asia. Although the prevalence of Helicobacter pylori infection is similar in Bhutan,
\nVietnam, andMyanmar, the incidence of gastric cancer is highest in Bhutan, followed by VietnamandMyanmar.We hypothesized
\nthat H. pylori virulence factors contribute to the differences. The status of cagA, vacA, jhp0562, and 𝛽-(1,3)galT(jhp0563) was
\nexamined in 371 H. pylori-infected patients from Bhutan, Vietnam, and Myanmar. Each virulence factor could not explain the
\ndifference of the incidence of gastric cancer.However, the prevalence of quadruple-positive for cagA, vacA s1, vacA m1, and jhp0562-
\npositive/𝛽-(1,3)galT-negative was significantly higher in Bhutan than in Vietnam andMyanmar and correlated with gastric cancer
\nincidence. Moreover, gastritis-staging scores measured by histology of gastric mucosa were significantly higher in quadruplepositive
\nstrains.We suggest that the cagA, vacA s1, vacA m1, and jhp0562-positive/𝛽-(1,3)galT-negative genotype may play a role in
\nthe development of gastric cancer.
