BACKGROUND: Hepatocellular carcinoma (HCC) with portal vein tumour thrombus (PVTT) signifies advanced disease, whether LT confers any survival superiority over resection remains uncertain. METHODS: A propensity score matched (PSM) analysis of liver transplantation (LT) and liver resection (LR) for HCC with PVTT was performed. RESULTS: A consecutive series of 88 patients who received either LT (10 DDLTs and 3 LDLTs) or LR (n=75) respectively were recruited. Before PSM, the LT group has a higher MELD score (17.3 vs. 7.8, P<0.001), lower serum AFP levels (96 vs. 2,164 ng/mL, P=0.017) and smaller tumour size (4 vs. 10 cm, P<0.001). The 5-year overall survival for LT and LR were 55.4% and 15.9% respectively (P=0.007). After matching for serum AFP levels and tumour size, 1-, 3- and 5-year overall survival for LT were 81 ng/mL, 3.9 cm, 80%, 70% and 70% and the corresponding rates for LR were 1,417 ng/mL, 5.3 cm, 51.8%, 19,6% and 9.8% (P value =0.12, 0.27 and 0.009 respectively). CONCLUSIONS: LT is associated with significantly better oncological outcomes in HCC patients with PVTT involving the lobar or segmental level. A modest expansion of selection criteria to include small HCC with segmental PVTT should be considered. 2021 Hepatobiliary Surgery and Nutrition. All rights reserved.
