ABSTRACT
Objective To evaluate the short-term curative effect and the safety of transcatheter arterial chemoembolization (TACE) therapy by using microspheres and lipiodol for hepatocellular carcinoma (HCC).Methods A total of 87 patients with pathologically proved HCC were randomly divided into the study group (n=44,using embospheres of 100-300 μm in diameter together with lipiodol) and the control group (n=43,using gelfoam particles of 350-560 μm in diameter together with lipiodol).Postopertaive biochemical (liver function and AFP) findings and imaging (CT and/or MRI) manifestations were recorded,and the clinical efficacy and adverse reactions were analyzed.Results TACE was performed in all 87 patients.After the treatment,both the disease benefit rate and the postoperative reduction in AFP level in the study group were remarkably better than those in the control group (P＜0.05),but postoperative liver function indexes were not significantly different from the preoperative ones (P＞0.05).The average number of interventional therapy within the follow-up period of 6 months in the study group was smaller than that in the control group (P＜0.05).No statistically significant differences in 6-,12-and 18-month survival rates existed between the two groups (P＞0.05).Conclusion In treating HCC,TACE by combination use of microspheres and lipiodol is safe,its short-term curative effect is more obvious than TACE by combination use of gelfoam particles and lipiodol,and it can reduce the times of interventional procedure.Before TACE,careful planning of the pre-treatment of hepatic artery-portal vein fistula and the superselective catheterization with micro catheter should be taken into consideration.
