CURRENT STATUS OF NATIONWIDE GASTRIC CANCER REGISTRATION AND ITS IMPLEMENTATION IN THE NATIONAL CLINICAL DATABASE

A nationwide gastric cancer registration project was started in 1968 by the Japanese Research Society for Gastric Cancer. After a 10-year period of inactivity, the Registration Committee of the Japanese Gastric Cancer Association (JGCA) rebooted the program in 2001. Hospitals voluntarily sent patient data for 5 years after they had undergone surgery to the JGCA data center. In 2010, 24,983 patients with primary gastric carcinoma who had undergone gastrectomy were enrolled, which covered about 45％ of the total patients in Japan by extrapolating the data in the National Clinical Database (NCD). The JGCA also conducted a retrospective nationwide registry in 2013 to investigate the outcomes of endoscopic mucosal resection or endoscopic submucosal dissection in patients with gastric cancer treated from 2004 through 2006. In the clinically effective database project of the Ministry of Health, Labor and Welfare, gastric cancer registration was implemented in the NCD from 2018. The retrospective data enrollment of patients with gastric cancer in 2011 and the prospective enrollment of patients in 2018 started. This implementation in the NCD may facilitate comprehensive gastric cancer registration, which will produce more evidence on the results of gastric cancer treatment.
