摘      要：BACKGROUND There is increasing interest in transplanting patients with hepatocellularcarcinoma (HCC) with tumors greater than 5 cm (Milan criteria).AIM To investigate possible prognostically-useful factors for liver transplantation inHCC patients with large *** In this clinical study, 50 patients with HCC who were transplanted at our LiverTransplant Center between April 2006 and August 2019 and had tumors greaterthan 6 cm maximum diameter were retrospectively analyzed. Their survival andfull clinical characteristics were examined, with respect to serum alphafetoprotein(AFP) and gamma glutamyl transpeptidase (GGT) levels. Kaplan-Meier survival estimates were used to determine overall survival and disease-freesurvival in these patients. The inclusion criterion was evidence of HCC. Exclusioncriteria were the presence of macroscopic portal vein thrombosis or metastasisand a follow-up period of less than 90 *** Using receiver operating characteristic curve (ROC) analysis, cutoff values of AFP200 ng/mL and GGT 104 IU/L were identified and used in this *** longer overall survival (OS) and disease-free-survival (DFS) were found in patients who had lower values of either parameter, compared withhigher values. Even greater differences in survival were found when the 2parameters were combined. Two tumor size bands were identified, in searchingfor the limits of this approach with larger tumors, namely 6-10 cm and 10 *** parameters in the 6-10 cm band reflected 5-year OS of 76.2% inpatients with low AFP plus low GGT vs 0% for all other groups. Patients withtumors greater than 10 cm, did not have low AFP plus low GGT. The mostconsistent clinical correlates for longer survival were degree of tumordifferentiation and absence of microscopic portal venous *** Serum levels of AFP and GGT, both alone and combined, represent a simpleprognostic identifier in patients with large HCCs undergoing liver transplantation.
