Transcatheter Hepatic Arterial Chemoembolization

DESCRIPTION

Transcatheter arterial chemoembolization (TACE) was developed as an alternative to conventional systemic or intra-arterial chemotherapy. Transcatheter hepatic arterial chemoembolization has been investigated as a treatment of isolated liver metastases and for unresectable hepatocellular carcinoma.

The rationale for TACE is that infusions of viscous material will occlude arterial blood, causing an infarct and subsequent necrosis of tumors in the infarcted region. The cytotoxic effect of arterial occlusion can be potentiated by labeling the infusion with radioactive isotopes or by adding cytotoxic drugs. The liver is especially amenable to such an approach given the distinct lobular anatomy of the liver, the existence of two independent blood supplies, and the ability of healthy hepatic tissue to compensate for tissue mass lost during chemoembolization. Another rationale is that TACE provides for effective local dose intensity while avoiding systemic toxicities associated with intravenous chemotherapy. However, TACE of the liver is associated with its own constellation of potentially life threatening toxicities and complications, such as severe postembolization syndrome, hepatic insufficiency, abscess, or infarction.

The chemoembolization procedure requires hospitalization. Prior to the procedure, the patency of the portal vein must be demonstrated in order to ensure an adequate post-treatment hepatic blood supply. Under local anesthesia and mild sedation, a superselective catheter is inserted via the femoral artery and threaded into the hepatic artery. Angiography is then performed to delineate the hepatic vasculature, followed by injection of the embolic chemotherapy mixture. Embolic material varies, but may include a viscous collagen agent, polyvinyl alcohol particles, or ethiodized oil. Typically, only one lobe of the liver is treated during a single session, with subsequent embolization procedures scheduled from 5 days to 6 weeks later. In addition, since the embolized vessel recanalizes, chemoembolization can be repeated as many times as necessary.

Note:  This policy does not apply to requests for venous occlusion of the portal vein.

ADDITIONAL INFORMATION

Child-Pugh score is a scoring system for liver function based on the presence of encephalopathy and/or ascites, and laboratory measures of bilirubin, albumin, and prothrombin time.

MELD (Model for End-Stage Liver Disease) is a scoring system for liver function based on a numerical scale. The scale ranges from 6 (less ill) to 40 (gravely ill). It is used for liver transplant candidates’ age 12 years and older. It gives an individual score based on how urgently a liver transplant is needed within the next three months. The number is calculated using the most recent laboratory tests for bilirubin, INR (formerly known as the prothrombin time) and serum creatinine.
