In unresectable hepatocellular carcinoma, TACE using Lipiodol/anti cancer agent emulsion is the standard treatment and reported as a significantly better treatment through randomized comparison study like Llovet, etc. than conservative treatment. Recently, doctors do transarterial chemoembolization with drug-eluting bead, and it is proved less side effect and better efficacy than conventional TACE using Lipiodol in Precision V study by Dr. Lammer, etc. But, it could not defined improved survival rate as expected. This study's purpose is evaluating treatment efficacy, survival rate and safety of TACE using drug eluting bead by comparing to conventional TACE using doxorubicin/Lipiodol emulsion for unresectable hepatocellular carcinoma.
