Liver transplantation for hepatocellular carcinoma in cirrhosis: prognostic parameters

Selection of patients suffering from hepatocellular carcinoma (HCC) in cirrhosis for liver transplantation is based upon the number and diameter of tumor nodules but not with vascular invasion. From 1989 to 2003, 1619 liver transplantations were performed in 1471 patients, including 163 patients with an HCC in cirrhosis. Selection criteria were a maximal diameter of up to 5 cm when the tumor appeared to be uninodular, or up to 3 cm in the case of two or three nodules and no vascular invasion prior to transplantation. The postoperative mortality rate was 1.7%. One-, 5- and 10-year survivals were 88%, 62%, and 51%, respectively. Among 1307 transplantations without HCC, the rates were 90%, 84%, and 76%, respectively (P < .0001). Multivariate analysis identified histopathological grading and vascular invasion to predict survival. A subgroup analysis showed 5-year survivals of 67% and 57% for well versus moderately differentiated tumors with vascular invasion. Liver transplantation is a safe and effective long-term treatment for small HCC in cirrhosis. Exeptions from the morphometric rules may be justified for patients with HCC in cirrhosis who show well or moderately differentiated tumors with vascular invasion.
