Malignant portal vein thrombosis is a contraindication to liver transplantation for hepatocellular carcinoma because of the high risk of its recurrence and the poor patient survival. With a newly developed immunosuppressant and a chemotherapeutic agent, however, living donor liver transplantation can be considered for a patient of hepatocellular carcinoma, showing a slow growth rate and good response for transarterial chemoembolization. We report a HBV related liver cirrhosis patient with HCC and portal vein tumor thrombus who underwent living donor liver transplantation and survived without recurrence of hepatocellular carcinoma for 18 months in our center.
