title: Liver transplantation for hepatocellular carcinoma: is there evidence for expanding the selection criteria?
abstract: A consequent application of the Milan criteria in patients undergoing liver transplantation for hepatocellular carcinoma (HCC) may lead to excellent long-term survival and a low incidence of recurrence. Expanding the selection criteria will result in more patients with hepatocellular carcinoma being potentially curative treated, but this approach is associated with at least a higher incidence of recurrence. Kaplan-Meier analysis of 110 patients, who underwent liver transplantation for HCC in our institution between 1987 and 2004, showed a significant improvement in patient survival with time. A change in criteria for patient selection may have contributed to the improved outcome. In 28 of 110 patients a recurrence of HCC was observed. In 82% of patients, who developed recurrence of carcinoma, the Milan criteria were not met. Dropout from the waiting list is common and several methods, including percutaneous ethanol injection, radiofrequency ablation, and chemoembolization, are used to prevent tumor progression and thus prevent dropout. As no randomized trials are available some uncertainty remains, whether these neoadjuvant procedures improve outcome. At present, there is no evidence that this approach enables expansion of the selection criteria. Hepatocellular carcinoma is a major indication for living related liver transplantation because the risk of dropout while waiting is negligible. Extension of the Milan criteria in the setting of living related liver transplantation may offer more patients a potentially curative treatment, without reducing the donor pool of organs for other patients on the waiting list with nonmalignant liver disease.
