Abstract:
Objective To investigate the expression and distribution of sialyl Lewis X in colorectal carcinoma and its relationship with carcinogenesis, progression and metastatic proclivity.Methods Microwave LSAB immunohistochemical technique was used to detect the expression of sialyl Lewis X in colorectal carcinoma and in normal mucosa. Immunoelectromicroscopic localization of sialyl Lewis X labelled by colloidal gold was also observed.Results The positive rate of sialyl Lewis X expression in primary colorectal cancer was 92 2%(83/90), and 16 7%(5/30) in normal mucosa. The positive rate was 100% in patients with lymphatic nodes metastasis, compared with that of negative nodes of 82 1% ( P
