Abstract
Although there are some difficulties in the management of the ABC classification system of gastric cancer risk assessment, there have been few systematic reports on them. We evaluated the 5-year follow-up conditions of the examinees who had undergone the ABC classification system. We reviewed the follow-up status in our and other institutions for 706 examinees (427 of Group A, 202 of Group B, 68 of Group C and 9 of Group D) who had undergone the classification at our institution in 2010. We investigated other institutions by mail. The results were as follows; 1) the rate of collecting questionnaires was 46% and was low; 2) the rate of examinees who underwent endoscopy or X-ray examinations within the first one year was 80∼90% and was high in all groups; 3) But it decreased to 50∼60 % after the second year, and did not increase after the third year. Based on these results and the importance of the management, we think that we should encourage examinees who had undergone the ABC classification system to receive gastric cancer screening examinations after the third year. Furthermore, we have begun a randomized control trial to evaluate the efficacy of encouraging examinees to have screening tests.
