Influence of preoperative transcatheter arterial chemoembolization on disease-free survival rates and overall suvival rates in patients with resectable large hepatocellular carcinoma

Abstract

Objective To investigate influence and significance of preoperative transcatheter arterial chemoembolization (TACE) on disease-free survival rates and overall suvival rates in patients with respectable large hepatocellular carcinoma(HCC). Methods One hundred and eight patients with respectable large primary liver cancers were prospectively randomized into two groups: preoperative TACE group(n=52) and one-stage operation group(n=56). We compared between two groups according to daughter nodules and tumor thrombus. Results There were no significant differences in the incidence of disease-free survival rates and overall suvival rates in the two groups. Conclusion Preoperative TACE for resectable large HCC should be used on bases of strict selection because it does not decrease the recrudescence rates and results in delayed surgery in some cases.
