METHODS: Patients transplanted for HCV and NASH at our institution from January 2000 to April 2011 were analyzed. All explanted liver histology and pre-trans- plant liver biopsies were examined by two specialist liver histopathologists. Patient demographics, disease free survival, explant liver characteristics and HCC features (tumour number, cumulative tumour size, vascular invasion and differentiation) were compared between HCV and NASH liver transplant recipients. RESULTS: A total of 102 patients with NA^SH and 283 patients with HCV were transplanted. The incidence of HCC in NASH transplant recipients was 16.7% (17/102). The incidence of HCC in HCV transplant recipients was 22.6% (64/283). Patients with NASH-HCC were statisti- cally older than HCV-HCC patients (P 〈 0.001). A signif- icantly higher proportion of HCV-HCC patients had vas- cular invasion (23.4% vs 6.4%, P = 0.002) and poorly differentiated HCC (4.7% vs 0%, P 〈 0.001) compared to the NASH-HCC group. A trend of poorer recurrence free survival at 5 years was seen in HCV-HCC patients compared to NASH-HCC who underwent a Liver trans- plantation (P = 0.11). CONCLUSION: Patients transplanted for NASH-HCC appear to have less aggressive turnout features com- pared to those with HCV-HCC, which likely in part ac- counts for their improved recurrence free survival.展开更多
