Abstract
Objective: To study the expression of CD15 mRNA,CD44v6 mRNA and nm23H1 mRNA in colon carcinoma and its relationship with clinical pathological parameters and prognosis of colon carcinoma. Methods: In situ hybridization was used to detect the expression of CD15 mRNA, CD44v6 mRNA and nm23H1 mRNA in 90 cases of colon carcinoma, and 53 cases were followed up for more than 5 years. Results: In 90 cases of colon carcinoma, the expression of CD15 mRNA,CD44v6 mRNA and nm23H1 mRNA were 84.4%,68.9%,66.7%, respectively. The high level expression of CD15 mRNA, CD44v6 mRNA and the low level expression of nm23H1 mRNA were positively corelated with the Dukes staging,serosa infiltration,lymph node and liver metastasis of colon carcinoma.The expression of CD15 mRNA in colon carcinoma was positively associated with that of CD44v6 mRNA and negatively with that of nm23H1 mRNA. Conclusion: CD15 mRNA,CD44v6 mRNA and nm23H1 mRNA play an up-regulation and a down-regulation role, respectively, and have a synergistic action in metastasis of colon carcinoma. CD15 mRNA can be used as a new biological index to predict the invasive potential of colon carcinoma and objectively evaluate the prognosis of patients.
