作者对49例经内镜检查后活检和摘除的胃息肉标本进行组织学分类和抗胃癌单克隆抗体MG7免疫组化研究。结果49例中炎性息肉12例(24.5％),增生性息肉19例(38.8％),腺瘤性息肉18例(36.7％)。癌变3例(61％)。MG7染色总阳性率为34.7％(17/49),其中腺瘤性息肉与炎性息肉MG7染色阳性率差异有显著性
The authors performed histological classification and immunohistochemical study on anti-gastric cancer monoclonal antibody MG7 in 49 cases of gastric polyps after biopsy and extirpation. Results In 49 cases, 12 cases (24.5%) were inflammatory polyps, 19 cases (38.8%) were hyperplastic polyps, and 18 cases (36.7%) were adenomatous polyps. 3 cases of cancer (61%). The total positive rate of MG7 staining was 34.7% (17/49). There was a significant difference in the positive rate of MG7 staining between adenomatous polyps and inflammatory polyps.
