分析２０９例早期胃癌临床病理学现象，认为４０～４９岁为早期胃癌好发的年龄段；浅表凹陷型（Ⅱｃ型）为代表类型，组织学类型中管状腺癌虽占优势，但低分化腺癌和印戒细胞癌已显示出上升趋势；讨论不同检诊手段对早期胃癌发现的价值。 209 cases of early gastric cancer were analyzed for clinicopathological findings. 40 to 49 years of age were considered to be the prevalent age of early gastric cancer; superficial depressed type (IIc type) was the representative type. Tubular adenocarcinoma was predominant in histological type, but poorly differentiated. Adenocarcinomas and signet-ring cell carcinomas have shown an increasing trend; the value of different examination methods for the detection of early gastric cancer has been discussed.
