Disease-specific analysis of liver transplant survival benefit, which encompasses both pre- and post-transplant events, has not been reported. Therefore, we evaluated the effect of alcoholic liver disease (AID) and hepatitis C virus (HCV) infection on waiting list mortality, posttransplant mortality, and the survival benefit of deceased donor liver transplantation using United States data from the Scientific Registry of Transplant Recipients on 38,899 adults placed on the transplant waiting fist between September 2001 and December 2006. Subjects were classified according to the presence/absence of HCV and ALD. Cox regression was used to estimate waiting list mortality and posttransplant mortality separately. Survival benefit was assessed using sequential stratification. Overall, the presence of HCV significantly increased waiting list mortality, with a covariate-adjusted hazard ratio (HR) for HCV-positive (HCV+) compared with HCV-negative (HCV-) HR = 1.19 (P = 0.0001). The impact of HCV+ was significantly more pronounced (P = 0.001) among ALD-positive (ALD+) patients (HR = 1.36; P < 0.0001), but was still significant among AID-negative (ALD-) patients (1411 = 1.11; P = 0.02). The contrast between ALD+ and ALD- waiting list mortality was significant only among HCV+ patients (HR = 1.14; P = 0.006). Posttransplant mortality was significantly increased among HCV+ (versus HCV-) patients (HR = 1.26; P = 0.0009), but not among ALD+ (versus ALD-) patients. Survival benefit of transplantation was significantly decreased among HCV+ compared with HCV- recipients with model for end-stage liver disease (MELD) scores 9-29, but was significantly increased at MELD >= 30. AlD did not influence the survival benefit of transplantation at any MELD score. Conclusion: Except in patients with very low or very high MELD scores, HCV status has a significant negative impact on the survival benefit of liver transplantation. In contrast, the presence of ALD does not influence liver transplant survival benefit. (HEPATOLOGY 2009; 50:400-406.)
