Hepatocellular carcinoma and portal vein invasion: results of treatment with transcatheter oily chemoembolization.

Abstract

When a tumor is limited in extent and hepatic function is preserved, transcatheter oily chemoembolization is effective and safe for the palliation of hepatocellular carcinoma and major portal vein invasion. However, when a parenchymal tumor is extensive, chemoembolization is associated with a poor response and a risk of hepatic failure.
