Abstract
For “early” hepatocellular carcinoma (HCC), surgery, orthotopic liver transplantation (OLT) and percutaneous ethanol injection (PEI) improve the natural history of the disease. We performed a retrospective study to evaluate the outcome of patients with cirrhosis and early HCC treated by PEI (n = 417) or OLT (n = 172). Overall, 589 patients with cirrhosis were studied. The proportion of patients in Child-Turcotte-Pugh (CTP) classes A, B, and C was 52.5%, 33.6%, and 13.9%, respectively. Most patients (78.9%) had solitary HCC. Overall 5-year and 10-year cumulative survival rates were 36.1% and 15.5% after PEI, and 66.3% and 49.1% after OLT, respectively (P < .0001). Overall 5-year and 10-year cumulative tumor-free survival rates were 25.3% and 18.0% after PEI, and 84.6% and 82.2% after OLT, respectively (P < .0001). When patients were sorted according to the severity of cirrhosis, mean survival times in PEI and OLT patients were 67 and 80 months in CTP class A (P = .05), 38 and 90 months in class B (P < .0001), and 31 and 95 months in class C (P = .0004). Similarly, mean tumor-free survival times in the 2 series of patients were 49 and 98 months in CTP class A (P < .0001), 39 and 121 months in class B (P < .0001), and 35 and 139 months in class C (P < .0001). In conclusion, this study challenges the therapeutic efficacy of PEI for patients with cirrhosis and early HCC, when compared to OLT: the proportion of both long-term survivors and tumor-free survivors was increased by OLT over PEI. The benefit of OLT extends to all patients, regardless of the degree of liver impairment. (Liver Transpl 2004;10:1355-1363.)
