[Risk of gastric cancer dependent on serological markers of atrophic gastritis: cohort study].

In a prospective study the risk of subsequent gastric cancer (GC) was assessed in persons aged 45-69 over 5 years after the initial testing with a set of serological tests (pepsinogen I, pepsinogen II, gastrin-17, antibodies to Helicobacter pylori). The presence of gastric atrophy markers was a significant predictor of GC in the forthcoming years. Non-invasive techniques may be used in the formation of high-risk groups, followed by GC active surveillance.
