Abstract
In Shizuoka city, endoscopic screening was introduced in April 2012, and approximately 5 years have passed. The percentage of examinees has increased from 7.1% in the year before its introduction to 10.6% in the current year, and the detection rate of gastric cancer using endoscopy has resulted in a significantly higher rate by 0.26% (ratio of early gastric cancer: 48.8%) than that by X-ray of 0.06% (ditto 69.4%). Although some tasks have been mentioned in the operation, securing the adequate number of endoscopists and countermeasures against the increasing screening costs are crucial issues among others. The gastric cancer screening accuracy control committee plans to add from 2018 the gastric cancer risk stratification test (the so-called ABC classification) at the same time of endoscopic examination for extracting the low-risk group (Helicobacter pylori-uninfected group) more accurately to perform examinations at an interval of once in 2 years or such that the burden of screening institutions could be reduced. Through the target aggregation of the high-risk group, it is expected that the limited resource of endoscopy can be operated more efficiently and the screening costs could also be reduced.
