Demographic, clinical and laboratory variables were recorded. RESULTS Median age for all patients was 53 years and 66% were men. Median model for end stage liver disease(MELD) score was 15. Median follow-up was 7- years. For retransplant patients, 84(56%) had ≥ 1 comorbidity. The most common comorbidity was renal impairment in 66(44.3%). WL mortality was higher in patients with ≥ 1 comorbidity(76% vs 53%, P = 0.044). CCI(OR = 2.688, 95%CI: 1.222-5.912, P = 0.014) was independently associated with WL mortality. Patients with MELD score ≥ 18 had inferior WL survival(LogRank 6.469, P = 0.011). On multivariate analysis,CCI(OR = 2.823, 95%CI: 1.563-5101, P = 0.001), MELD score ≥ 18(OR 2.506, 95%CI: 1.044-6.018, P = 0.04), and requirement for organ support prior to LRT(P < 0.05) were associated with reduced post-LRT survival. Donor/graft parameters were not associated with survival(P = NS). Post-LRT mortality progressively increased according to the number of transplanted grafts(Log-Rank 18.455, P < 0.001). Post-LRT patient survival at 1-, 3- and 5-years were significantly inferior to those of PLT at 88% vs 73%, P < 0.001, 81% vs 71%, P = 0.018 and 69% vs 55%, P = 0.006, respectively. CONCLUSION Comorbidity increases WL and post-LRT mortality. Patients with MELD ≥ 18 have increased WL mortality. Patients with comorbidity or MELD ≥ 18 may benefit from earlier LRT. LRT for ≥ 3 grafts may not represent appropriate use of donated grafts.展开更多
