Evaluation of Overall Survival and Disease-Free Survival in Patients Receiving Liver Transplantation for Hepatocellular Carcinoma and Comparison of Living Versus Deceased Donor Liver Transplants: Results of 15 Years of Experience

Objective: Research comparing patients who received liver transplantation (LT) for hepatocellular carcinoma (HCC) has produced varying outcomes regarding survival and disease-free survival. The objective of this study is to determine the factors that influence the disease-free and overall survivals of those who have undergone LT for HCC and to compare the outcomes of living versus deceased donor liver transplants.

Materials and Methods: We retrospectively analyzed data on patients aged 18 and above who received LT for HCC from 2006 to 2022. Patients with a follow-up period of less than 6 months and who did not meet the University of California San Francisco criteria were excluded. The data from 58 patients were analyzed. We split the patients into living donor liver transplantation (LDLT) (group 1) and deceased donor liver transplantation (DDLT) (group 2).

Results: The mean age was 56 ± 8.1 years. There were 49 males and 9 females. The median of the alphafetoprotein (AFP) level and model for end-stage liver disease score was 10.1 ng/mL and 11, respectively. The 1-, 3-, 5-, and 10-year disease-free survival rates were 86%, 76.5%, 76.5%, and 76.5%, respectively. The survival rates for the same periods were 94.8%, 74.9%, 70.6%, and 67.4%. The receiver operating characteristic analysis revealed that AFP > 31.8 ng/mL and a total tumor size >3.85 cm raise the likelihood of HCC recurrence post-LT.

Conclusion: Based on the current literature, the overall survival and disease-free survival rates are influenced by factors such as AFP value, total tumor number, and total tumor diameter. In our study, the AFP value and total tumor size had an impact on the recurrence of HCC, and the survival rates were comparable on LDLT and DDLT.
