早期胃癌的临床病理特点

观察了192例早期胃癌的临床病理特点，其中粘膜内癌103例,粘膜下癌89例。结果显示，早期胃癌多位于胃窦部（42．71％），以凹陷型为主（67．19％），且多为髓样癌（53．13％），组织类型以分化型管状腺癌及印戒细胞癌为主，分别为41．67％及25．52％。浸润型占比例较低（9．90％），但易引起胃壁淋巴管浸润及淋巴结转移。本组早期胃癌胃壁淋巴管浸润率为30．73％，淋巴结转移率为12．50％。女性发病年龄及出现淋巴结转移的年龄均较男性提前。

THE CLINICOPATHOLOGICAL CHARACTERISTICS OF EARLY GASTRIC CANCER

The pathological characteristics of 192 early gastric cancer were observed. Of them 103limited to mucosa and 89 invaded into submucosa-The discovery showed that early gastric cancer was mainly located at antrum of stomach (42. 71 % ),grossly was mainly in depressed type (67. 19% ).and most of them were medullary type (53. 13% ),histologically well differentiated tubular adenocarcinoma (41. 67 % ) and signet ring cell carcilloma (25. 52% ) took large amount. Although infiltration type of growth took a little part (9. 90% ), it easily causes lymphatic vessel invasion of gastric wall and lymph node metastasis. In this group, the rates of lymphatic vesse1 invasion and lymph node metastasis were 30. 73% and 12. 5% respectively. The age of female, who had the disease and lymph node metas-tasis, was early compared with that of male.
