Relationship between multiple adhesion molecules expression in gastric carcinoma and organic selection of gastric carcinomatous metastasis / 中国实用内科杂志

ABSTRACT

Objective To evaluate the effect of multiple adhesion molecules ICAM-1、CD_ 44 V6、CD_ 28 、E-cad and CEA in organic selection of gastric carcinomatous metastasis.Methods Eighty-four gastric carcinoma cases(32 cases without metastases,52 cases with transfer to liver、marrow、lymphonode、lung、kidney or belly cavity),were take operation sample or tissue under gastroscopy,being made cells single by primary culture,then were detected the expression of 5 kinds of adhesion molecules by ABC immunohistochemistry,positive rate was recorded.Results ICAM-1 had high expression in cases with marrow or lung metastasis,while low expression in cases with lymphonode metastasis.CD_ 44 v6 had high expression in cases with lymphnode or liver metastasis.CD_ 28 had high expression in cases with liver、lung or kidney metastasis.E-cad had high expression in cases with marrow metastasis,while low expression in cases with other metastasis.CEA had especially high expression in cases with liver、belly cavity or lymphnode metastasis.Conclusion High or low expression of adhesion molecules ICAM-1、CD_ 44 V6、CD_ 28 、E-cad and CEA plays a certain role in organic selection of gastric carcinomatous metastasis.
