 Endoscopic submucosal Dissection(ESD)for early gastric cancer has become widespread in Japan and eradication therapy for Helicobacter pylori has become a standard treatment after ESD. In this study, we analyzed metachronous gastric cancer(MGC)after ESD and successful eradication therapy. 39lesions(33 second and 6 third lesions of gastric cancer)were detected as MGC in 33 patients after ESD and successful eradication therapy. The time to detection for secondary gastric cancer was 28.8 months on average, 15.0 months in median(range 5-120). Male/female ratio was 31/2, and the median size of MGC was 12.3mm(range 3-30). The interval between the time of detection for MGC and the time of the last examination was 8.5(5-19)months. Most of the MGC were the depressed type, intramucosal cancer and existed with severe gastric atrophy. For further analysis, we have to do long term follow up in patients after ESD.
