Introduction
Hepatocellular carcinoma (HCC) is a primary tumor of the liver, which usually develops in the setting of chronic liver disease, particularly in patients with chronic hepatitis B and hepatitis C. Current guidelines recommend transarterial chemoembolization (TACE) as the standard treatment of Barcelona Clinic Liver Cancer-B patients. The aim of this work is to compare the efficacy, safety, feasibility, and cost-effectiveness of drug-eluting bead (DEB)-TACE versus combined conventional transarterial chemoembolization (c-TACE)+percutaneous ethanol injection (PEI) for improving the outcome of large HCC.
Patients and methods
In all, 75 patients with large HCC were included in this study: 30 patients were treated by combined c-TACE + PEI and 45 patients were treated by DEB-TACE.
Results
By comparison of the results of the combined c-TACE + PEI group with the DEB-TACE group, there was no significant difference in tumor response, with better results in the combined c-TACE + PEI group and significant decrease in the median value of the serum level of α-fetoprotein after treatment among patients treated with combined c-TACE + PEI ( = 0.004), and a statistically significant difference in the median value after treatment between the two groups ( = 0.036).
Conclusion
Results of combined c-TACE + PEI and DEB-TACE are comparable, but the cost of a DEB-TACE session is three times that of c-TACE + PEI, and thus cost-effectiveness analyses recommend the use of combined c-TACE + PEI (less cost) in the treatment of large HCC; in addition, there was a significant reduction in the level of α-fetoprotein after combined c-TACE+PEI treatment.
