Transcatheter chemoembolization of unresectable hepatocellular carcinoma: current knowledge and future directions

Transarterial chemoembolization (TACE) is considered the gold standard for the treatment of unresectable hepatocellular carcinoma (HCC) in patients with a preserved liver function and in the absence of clear extrahepatic tumor spread. This review article deals with the radiological and clinical workup, the interventional technique of chemoembolization for HCC and gives an overview of the common as well as some rare and dramatic complications of TACE. Finally, some new trends and advances in clinical research with regard to the interventional management of HCC are discussed.
