Background: Hepatocellular carcinoma (HCC) is the leading primary liver tumor and a main indication for transplant. Transplant criteria are based on clinicopathologic features, meanwhile adequate downstaging and molecular mechanisms are getting more attention in evolving therapeutic algorithm of HCC. The aim of our study was to overview the results of the Hungarian Liver Transplant Program in the field of HCC and introduce new aspects of personalized treatment options.
Methods: We performed retrospective analysis of survival and tumor recurrence of HCC-associated liver transplant recipients between October 2013 and December 2020. Patients were categorized in Milan criteria (MC), beyond MC but within University of California, San Francisco (UCSF), and beyond UCSF criteria groups after pathologic examination of the explanted liver. Demographic data and preoperative locoregional treatments were assessed.
Results: A total of 529 primer liver transplants were performed, 88 because of HCC. A total of 87 patients had underlying cirrhosis because of hepatitis C (54%), alcohol-related liver disease (33.7%), hepatitis B (4.5%), or unknown etiology. A total of 55.6% of the patients had at least one locoregional treatment. A total of 67.4% of the patients were within MC, 5.6% were within UCSF criteria, and 27% were beyond UCSF criteria. The 1-, 3-, and 5-year survival rates were 80%, 79%, and 75%. The outcome was better in early-stage tumors, but the difference was not significant (P = .745) CONCLUSIONS: The favorable survival in our department legitimates the strict transplant criteria of HCC. Adequate locoregional therapy as downstaging can expand recipient pool. Molecular tumor profiling may lead to personalized treatment of HCC.
