结直肠癌中 ICAM-1和 VCAM-1的表达和临床意义

摘要

Objective To investigate the expression of ICAM-1 and VCAM-1 in colorectal carcinoma and the rela-tionship between ICAM-1, VCAM-1 and the occurrence, the metastasis of colorectal carcinoma, and to analyze the significance. Methods Immunohistochemistry staining(S-P method) was used to detect the expression of ICAM-1 and VCAM-1 on consecutive section in 78 cases of colorectal carcinoma and normal mucosa and 42 cases of colorec-tal adenomas. Plasma was obtained from 78 patients with colorectal carcinoma and 40 healthy volunteers prior sur-gery, by an enzyme-linked immunosorbent assay (ELISA). Results There was significant difference between the high expression of ICAM-1 and VCAM-1 in colorectal carcinoma and the low expression in normal mucosa and ade-noma(P 0. 05),but had significantly statistical difference between lymph node metastasis and Dukes stage(P 0．05)，但与淋巴结转移及 Dukes 分期有相关性(P <0．01)。结论 ICAM-1和 VCAM-1在 CRC 原发病灶组织和外周血中均呈高表达，且随着肿瘤浸润转移的发展而增加，其可能对肿瘤的进展、恶性程度的判断及发生机制具有重要意义。
