胃癌生长中组织学类型和生长方式的变化

Changes of Histological Type and Growth Pattern during Development of Gastric Carcinoma

通过62例粘膜下层早期胃癌和342例进展期癌的光镜观察，发现：1，部分胃癌在向深层发展中，组织学类型可以转变；2，胃癌生长方式与癌组织所在部位（层次）、组织学类型有关，同一病例粘膜层癌和深层癌的生长方式可以不同。结论：胃癌的生长是一个动态变化过程．形态学上表现为组织学类型和生长方式的改变。

Through histological observation under light microscopy in 62 cases of early gastric carcinoma and 342 cases of advanced gastric carcinoma, we found that: 1. The histological type of some gastric carcinomas had changed as tumor invaded deeper layers of gastric wall. 2. The growth pattern of gastric carcinoma was associated with its histological type and the site (layer) where the carcinoma tissue was located, and so in the same case the growth pattern of carcinoma located in the mucosal layer might be different from that in deeper layers. It has been concluded that morphologically, the histological type and growth pattern of gastric carcinoma may undergo changes as the carcinoma develops.
