Analysis of tumor characteristics revealed that the pre-transplant treatment (including transarterial chemoembolization (TACE), radiofrequency ablation (RFA), chemotherapy, cryoablation, surgery), number of tumors, largest tumor diameter, sum of tumor diameters, tumor staging, and pre-transplant α-fetoprotein (AFP) level were all similar among four groups. Here, AFP is linked to neoplasm.
