Expression of vascular cell adhesion molecule-1 in breast carcinoma and its clinical significance / 中国普通外科杂志

ABSTRACT

Objective To investigate the relationship between the expression of VCAM-1 and oncogenesis, tumor angiogenesis and metastasis in breast carcinoma. Methods Using semi-RT-PCR and immunohistochemistry technique, specimens from 63 patients of breast cancer,20 of fibroadenoma were detected for expression of VCAM-1.Microvessel density(MVD) was counted by endothelial cells immunostained using monoclonal antibody CD34.Circulating sVCAM-1 concentrations were measured by enzyme linked immunosorbent assay. Results Of 63 breast cancer tumor tissues VCAM-1 mRNA was detected in 37 cases. The rate of VCAM-1 mRNA in the primary breast cancer tissues were significantly higher than that in the adjacent non-cancerous tissues and benign fibroadenoma tissues (?2=43,P
