Impact of the timing of Helicobacter pylori eradication on the risk of development of metachronous lesions after treatment of early gastric cancer: a population-based cohort study

Abstract

Prescription of H pylori eradication therapy within 1 year after gastric cancer treatment reduces the risk of development of metachronous gastric neoplasms compared with a late prescription of eradication therapy in patients undergoing endoscopic resection and those undergoing surgery.
