 Background:In esophagogastric junction adenocarcinoma, both GCA(gastric cardiac adenocarcinoma)and BEA(Barrett's esophageal adenocarcinoma)originated in short-segment Barrett's esophagus are included. This study aimed to compare background factors and clinical outcomes of ESD(endoscopic submucosal dissection)between GCA and BEA.

 Materials and Methods:We enrolled 139 patients who underwent ESD between 2006 and 2014 at the cancer institute hospital. We compared background factors, endoscopic features, and clinical outcomes of endoscopy between 54(38.9%)patients with BEA and 85(61.1%)patients with GCA.

 Results:The curative resection rate of GCA was higher than that of BEA. There were no significant differences in background factors between the two groups. The risk factor for non-curative resection, lymphovascular invasion, and depth of invasion was higher in the BEA group than in the GCA group.

 Conclusion:Although there were no significant differences in background factors, BEA was found to be a risk factor for the non-curative resection of ESD.
