Intraarterial Therapies for the Management of Hepatocellular Carcinoma

Tushar Garg et al. Cancers (Basel). .

Abstract

Image-guided locoregional therapies play a crucial role in the management of patients with hepatocellular carcinoma (HCC). Transarterial therapies consist of a group of catheter-based treatments where embolic agents are delivered directly into the tumor via their supplying arteries. Some of the transarterial therapies available include bland embolization (TAE), transarterial chemoembolization (TACE), drug-eluting beads-transarterial chemoembolization (DEB-TACE), selective internal radioembolization therapy (SIRT), and hepatic artery infusion (HAI). This article provides a review of pre-procedural, intra-procedural, and post-procedural aspects of each therapy, along with a review of the literature. Newer embolotherapy options and future directions are also briefly discussed.

Keywords: bland embolization; drug-eluting beads–transarterial chemoembolization; hepatic artery infusion; hepatocellular carcinoma; selective internal radioembolization therapy; transarterial chemoembolization.

Patient with right lobe HCC with extension into the hepatic vein causing thrombosis. Pre-procedural investigation showed 30% shunt fraction, and therefore the patient was treated with cTACE. (A) Pre-procedural coronal CT shows right lobe HCC lesion with hepatic vein thrombosis. (B) A 99mTc-MAA SPECT/CT shows a lung shunt with a lung shunt fraction of 30%. (C) Intraoperative CT showing good lipiodol uptake in the treated lesion areas. (D) Follow-up MRI showing reduced non-enhancing HCC and hepatic vein thrombus due to good response after treatment.
