摘要: Background. Carbohydrate antigens in cancer cells are considered to be involved the binding of endothelium during metastasis. Methods. Seventy cases primary oral squamous cell carcinoma (SCC) were obtained from biopsy specimens and analyzed immunohistochemically using an antibody against sialyl Lewis (Le) a or Le x . Flow cytometry was performed detect expressed on SCC lines. Results. The expressions , but not tumors significantly correlated nodal metastasis; 71% metastatic express with positive no demonstrated high incidence metastasis (80%). A flow cytometric study line, which can metastasize nude mice, level Conclusion. expression may thus therefore predict poor prognosis SCC.
