Successful Embolization of Hepatocelluar Carcinoma With Yttrium-90 Glass Microspheres Prior to Liver Transplantation

We report a case of a patient with end-stage liver disease secondary to hepatitis C, complicated by a large hepatocellular carcinoma. Because of the size of the tumor exceeded the Milan criteria, he was not a candidate for liver transplantation. However, after two treatments with yttrium-90 glass microsphere infusions, the tumor became smaller and the patient's α-fetoprotein level dropped to normal range. He was listed for transplantation and subsequently received a deceased donor liver transplant. Two years after his transplantation, he remains tumor free and has normal α-fetoprotein levels. This is the first reported case in the literature of using yttrium-90 microspheres as a bridge to liver transplantation in a patient with a large hepatocellular carcinoma. This therapy should be considered in patients with cirrhosis and large hepatocellular carcinomas exceeding current size criterion, who would otherwise be good candidates for transplantation.
