 A total of 500 patients who received initial endoscopic submucosal dissection(ESD)for early gastric cancer were evaluated retrospectively. Patients were followed-up by endoscopy for 1〜10years(median, 5.2years). Synchronous multiple cancers were detected in 119 patients(24%), and 61patients(12%)developed 76 metachronous multiple cancers. Of 76metachronous cancers, three(4%)were detected as being SM2 cancers. The Kaplan─Meier curve of the cumulative incidence of metachronous cancers was significantly increased in patients with synchronous cancers. No difference was observed between Helicobacter pylori-negative and H. pylori-positive patients. In endoscopic examination before and after ESD for patients with early gastric cancer, we should consider synchronous and/or metachronous cancers, as they may account for approximately 30% of cases.
