Among 272, 397 cases who underwent primary photof luorogram in gastric mass survey during a period of 5 years between 1982 to 1986, 37, 658 (13.8%) cases were diagnosed to require close examinations. Among them, 11, 802 cases received close examinations at the Asahikawa Cancer Detection Center, and 218 cases of stomach cancer were detected. The analyses of these stomach cancers resulted in the following classifications: 154 cancer cases detectable with photofluorogram, 39 cases with upper GI series, and 25 cases with endoscopy. Of 7, 702 males aged between 30 to 79, who underwent close examinations, 5, 052 cases initially received routin upper GI series (X-ray group), and 2, 650 initially examined with endoscopy (endoscopy group). Cancers were detected with endoscopy in 9 cases (0.18%) of the X-ray group and in 10 cases (0.38%) of the endoscopy group. This indicated that on close examinations during gastric mass survey, the application of endoscopic examinations at the initial stages showed higher cancer detection ratio compared with performing direct X-ray tests at the initial stages.
