From 1963 to 1985, 1038 cases of early gastric cancer were treated at Fukui Prefecture Hospital. From a study that was undertaken, the incidence of early gastric cancer in cases of a resected gastric cancer was found to have increased. The age distribution and the sex ratio of early gastric cancer patients had not changed annually, though early gastric cancers that were detected by a mass survey or comprehensive physical examinations had increased. Macroscopically, early gastric cancers of the elevated type decreased while those of the depressed type increased. With regard to size, lesions smaller than 1.0 cm have increased during the past 5 years. Histologically, well-differentiated tubular adenocarcinomas have increased annually. The grade of intestinal metaplasia in the stomach has not changed.
1963年至1985年期间，福井县医院共治疗了1038例早期胃癌患者。通过一项研究发现，在切除的胃癌病例中，早期胃癌的发病率有所上升。早期胃癌患者的年龄分布和性别比例每年没有变化，不过通过大规模调查或全面体检检测出的早期胃癌有所增加。从宏观上看，隆起型早期胃癌减少，而凹陷型早期胃癌增加。在大小方面，过去5年中小于1.0厘米的病变有所增加。从组织学上看，高分化管状腺癌每年都在增加。胃的肠化生程度没有变化。
