Pathological characteristics of early gastric cancer in Chinese patients were analyzed. The 1477 cases were collected from 55 hospitals in China. The peak age of early gastric cancer patients was between 50-59 years old. The incidence in female before 50 years old was higher than that in male but reversely after this age. Highly differentiated carcinomas were more frequently found in those cancer foci of < or = 0.5 cm in diameter. It was also detected that the bigger of its size the deeper of its infiltration was in those cancer foci between < 6 cm. In these early gastric cancers, type IIc was the commonest one (39.5%) whereas the least one was type I (4.0%). The most common site was in lower part of the stomach and less found in the upper part. Prognosis of the highly differentiated carcinoma was better than that of others. More signet ring cell carcinomas were found in early gastric cancer than in advanced cases, especially in the intramucosal cancers. Lymphatic metastasis was more (17.0%) in type IIc+III and the least is in type I (3.6%). Comparing with the Japanese cases of early gastric cancer, it was found that the peak age of early gastric cancer patients in Chinese was 10 years younger than that in Japanese patients. In the latter, its highest incidence age was 70 years old and most of them occurred in middle part of the stomach. In Japanese patients, type III and mucinous adenocarcinoma of EAG was hardly found.
分析了中国患者早期胃癌的病理特征。收集了来自中国55家医院的1477例病例。早期胃癌患者的年龄高峰在50 - 59岁之间。50岁之前女性的发病率高于男性，但50岁之后则相反。直径≤0.5 cm的癌灶中高分化癌更为常见。还发现，直径<6 cm的癌灶，其大小越大浸润越深。在这些早期胃癌中，IIc型最为常见（39.5%），而I型最少（4.0%）。最常见的部位是胃下部，上部较少见。高分化癌的预后优于其他类型。早期胃癌中发现的印戒细胞癌比进展期病例更多，尤其是在黏膜内癌中。IIc + III型的淋巴转移更多（17.0%），I型最少（3.6%）。与日本早期胃癌病例相比，发现中国早期胃癌患者的年龄高峰比日本患者年轻10岁。在日本患者中，其最高发病年龄为70岁，大多数发生在胃中部。在日本患者中，几乎未发现EAG的III型和黏液腺癌。
