Abstract
Ever since it was recognized that Helicobacter pylori (hereinafter referred to as Hp) was deeply associated with the onset of gastric cancer, efforts have been made to establish a new and more effective check-up approach in gastric cancer screenings toward indentifying individuals in the high-risk group using a serologic method, so that gastric cancers can be detected in the early stages. Even though there is clear evidence that the mass screening of gastric cancer by means of the ongoing radiological method has been contributing to the lowering of the mortality rate for gastric cancer, it is still necessary to make changes by introducing a new approach to the current screening method employed in gastric cancer examinations by the radiological investigation of the upper GI tract. In this age of Hp, we would like to propose a new diagnostic criterion for indentifying high-risk cases based on radiological findings on the gastric mucosa in gastric cancer screenings to be conducted in Nara Prefecture.
