Objective To summarize the advancement on Lewis-Selectin metastasis pathway and anti-tumor treatment of cimetidine in colorectal cancer.
Methods Domestic and international publications involving Lewis-Selectin metastasis pathway and antitumor role of cimetidine in recent years were collected and reviewed.
Results The expression of sialyl Lewis X (sLeX) was most significant in Lewis-Selectin metastasis pathway in colorectal cancer. Cancer cells could interact with E-selectin and P-selectin of activated vascular endothelial cells by sLeX ligand on the cell surface, thereby prompting invasion and metastasis. Cimetidine could inhibit the growth of tumor, improve immune response of the host to tumor cell, inhibit angiogenesis of tumor and metastasis. The curative effect of cimetidine on colorectal cancer patients with positive sLeX expression was better than that with negative sLeX expression.
Conclusion Lewis-Selectin metastasis pathway is one of the important metastasis pathway in colorectal cancer. Cimetidine can prevent metastasis of colorectal cancer by blocking sLeX expression.
