Key clinical point: Intensive index endoscopy in individuals with high risk for gastric cancer does not reduce the detection rate of new gastric cancers after 1 year.
Major finding: The rate of early gastric cancer detection by index endoscopy was similar to that of new gastric cancer detection by surveillance endoscopy within 15 months after index endoscopy (3.0% vs 2.6%).
Study details: This case-control secondary analysis of the data of 4523 individuals with high risk for gastric cancer from a randomized clinical trial who received index endoscopy comprising two examinations of the stomach with white light and narrow-band imaging.
Disclosures: This study was sponsored by Kyoto University, Japan, and Olympus Medical Systems. Some authors reported receiving grants or personal fees from various sources, including Olympus Medical Systems.
