Abstract:
Objective:The aims of this study were to compare the efficacy between salvage liver transplantation (sLT) and rehepatectomy (RR) basing on the propensity score matching (PSM), and to explore the prognositc factors of patients with recurrent hepatocellular carcinoma (HCC).Methods:124 patients with intrahepatic recurrence after hepatectomy in our center from January 2012 to August 2018 were divided into sLT group( n=46) and RR group( n=78). 34 patients were selected for data analysis base on 1∶1 propensity score matching (PSM). The advantages and disadvantages of the two surgical methods and the prognostic factors of the patients were discussed by comparing the basic clinical data, OS and DFS of the two groups before and after matching. Results:Before matching, the pre-operative serum total bilirubin, the occurrence of multiple tumors, the proportion of preoperative TACE and the proportion of patients within Milan criteria of the sLT group were higher than those of the RR group, and the maximum tumor diameter of the sLT group was shorter than that of the RR group ( P<0.05); the time of operation, the amount of intra-operative blood loss, the positive of MVI and the proportion of postoperative Clavien grade Ⅲ and above of RR group were higher than those of RR group ( P<0.05). After matching, the operation time, intra-operative blood loss and the proportion of postoperative complications of sLT group were higher than those of RR group; there was nosignificant difference between 1-, 3- and 5- years OS of sLT group and RR group( P>0.05), the 1-, 3- and 5-years DFS of sLT group were better than those of RR group( P<0.05); AFP≥100 μg/L was the independent risk factor of OS, and the type of operation and AFP≥100 μg/L were independent risk factors of DFS. Conclusions:The pre-operative condition of sLT group was more severe, and the operation time, intra-operative blood loss and post-operative severe complication rate of sLT group were higher than those of RR group, and the DFS time of sLT group was longer than that of RR group, but there was no significant difference in OS between the two groups.
