胃癌CEA免疫组织化学和粘液组织化学的研究

CEA IMMUNOHISTOCHEMICAL MUCOUS HISTOCHEMICAL STUDY FOR GASTRIC CANCER

从胃大部份切除证实胃癌118例中,CEA产生性胃癌占86.14％,CEA非产生性胃癌占13.56％。胃癌组织类型与CEA阳性率有关,印戒细胞癌、粘液腺癌阳性率100％;管状腺癌阳性率92.86％;乳头状腺癌阳性率88.98％;低分化腺癌阳性率85.2％;未分化癌阳性率50％。CEA产生性胃癌,经粘液组织化学染色证实属酸性粘液者41.2％,CEA非产生性胃癌属酸性粘液者18.8％,两者比较存在着显著差异。

One hundred and eighteen subtotal gastrectomy samples proved to be gastriccarcinoma pathologically were studied with HE stain. The results indicated thethe histological types of gastric carcinoma were related to CEA positive rate, suchas the CEA positive proportion of the mucous adenocarcinoma and the signet cellcarcinoma were the highest (100%) and the undifferentiated carcinoma was thelowerest(50%). In addition, the acid mucous of CEA produced gastric cancer andnon-CEA produced gastric cancer also had significanet difference.
