Objective:To investigate the effect of preoperative intraarterial infusion chemotherapy on the expression of Smad4 in colorectal carcinoma.Methods:15 cases of advanced colorectal carcinoma were treated with preoperative intraarterial infusion chemotherapy
18 cases treated with systemic chemotherapy and 21 cases treated with operation served as the control group.The expression of Smad4 was detected by immunohistochemic S-P method.Result:Among the three groups
the expression level of Smad4 gradually increased(P<0.05).Positive expression of Smad4 in three groups were 19.0%(4/21)(operation served)
61.1% (11/18) (vein chemotherapy) and hespectively 93.3% (14/15) (preoperative intraarterial infusion chemotherapy) (P<0.05). Conclusion:Preoperative intraarterial infusion chemotherapy could induce the high level of Smad4 expression
so it could be a more effective chemotherapy than systemic chemotherapy.
