| Outline of Final Research Achievements |
CT and MRI examinations have increased more in Japan than mammography examinations. The supply of mammography units has not been sufficient compared with the supply of CT and MRI units. A rapid increase in the prevalence of gastritis was observed in individuals aged 45 to 64 years after health insurance coverage of *H.pylori* eradication for chronic gastritis among asymptomatic people by health insurance.
Estimation of proportion of overdiagonsise for cancer screening has been calculated based on the results of randomized controlled trials, cohort studies, time series and modeling approach.
Endoscopic screening for gastric cancer has been performed in Niigata city, but there are no system other municipalities. The decrease of mortality rates from gastric cancer was larger in Niigata City than in other municipalities in Niigata prefecture. The gap between localized and regional/distant gastric cancer suggests overdiaganosis of gastric cancer by endoscopic screening.
