Forty-nine cases of gastric polyp (GP) were studied by histologic classification and immunohistochemical localization of monoclonal antibody MG 7 against gastric carcinoma. There were 12 cases (24.5%) of inflammatory polyp; 19 cases (38.8%) of hyperplastic polyp and 18 cases (36.7%) of adenomatous polyp. 3 cases (6.1%) of GP were malignant, among which 2 (11.1%) were adenomatous polyp and 1 (5.3%) was hyperplastic polyp. Seventeen cases (34.7%) of GP were MG 7 positive by ABC method, including 7 (36.8%) of hyperplastic polyp and 10 (55.5%) of adenomatous polyp. The inflammatory polyps were negative, and all of the cases with malignancy were strongly positive. The results showed that both GP and gastric carcinoma express MG 7 related antigen. These suggest that adenomatous polyp and hyperplastic polyp are closely related with gastric carcinogenesis.
对49例胃息肉(GP)进行了组织学分类及抗胃癌单克隆抗体MG 7的免疫组化定位研究。其中炎性息肉12例(24.5%);增生性息肉19例(38.8%);腺瘤性息肉18例(36.7%)。胃息肉恶变3例(6.1%),其中腺瘤性息肉2例(11.1%),增生性息肉1例(5.3%)。采用ABC法检测显示,17例(34.7%)胃息肉MG 7阳性,其中增生性息肉7例(36.8%),腺瘤性息肉10例(55.5%)。炎性息肉为阴性,所有恶变病例均呈强阳性。结果表明胃息肉与胃癌均表达MG 7相关抗原。提示腺瘤性息肉和增生性息肉与胃癌发生密切相关。
