Clinical efficacy of locoregional therapy prior to living donor liver transplantation for hepatocellular carcinoma based on UCSF criteria
Abstract Background The study analyzed the loco-regional therapy outcomes prior to living donor liver transplantation (LDLT), to provide additional information for decision-making regarding therapeutic strategy for hepatocellular carcinoma (HCC) patients. Methods A total of 308 consecutive patients undergoing LDLTs for HCC between August 2004 and December 2018 were retrospectively analyzed. Patients subjected to loco-regional therapy prior to LT were grouped and the outcomes were compared. Results Overall, HCC recurrence after LDLT were detected in 38 patients (12.3%) during the follow-up period. By the end of the study, 205 patients, 6 of whom with recurrent HCC, were alive. Patients who had radiological imaging beyond the University of California at San Francisco (UCSF) criteria had significant inferior outcomes for both recurrence-free survival (RFS, p = 0.0005) and overall survival (OS, p = 0.0462) despite receiving loco-regional therapy as down-staging intention. Moreover, patients with profound tumor necrosis (TN) had a superior RFS at 3 and 5 years (97.4% and 93.8%, respectively), compared with others. Conclusion LDLT gains a satisfactory result based on the expanded UCSF criteria for HCC. However, the loco-regional therapy prior to LDLT does not seem to provide benefit unless a profound TN is noted.
