Other
Other related information Healthy people who received H. pylori eradication in or after Feb. 2013 are enrolled. Biopsy samples are taken by endoscopy from 2 fixed points in the antrum and gastric body (the lesser curvature) for DNA methylation analysis at least 10 months after successful H. pylori eradication therapy. Methylation levels of preselected genes are measured by quantitative methylation-specific PCR. Blinded to methylation information, people are followed up annually by endoscopy for 5 years to detect primary gastric cancers. An association between DNA methylation levels and the incidence of primary gastric cancer is analyzed.
