Abstract
Liver transplant (LT) is the standard therapy for end-stage liver disease. Advances in surgical techniques and immunosuppression protocols improved the results of LT by increasing long-term survival. Nevertheless, an adequate match between the donor and recipient is paramount for avoiding futile liver transplants. We aimed to identify the prognostic factors in donor-recipient LT matching. Retrospective analysis of adult LT was conducted from January 2006 to December 2018, which included the following transplant modalities: deceased donor LT (DDLT), living donor LT (LDLT), combined liver-kidney transplant (CLKT), and domino LT (DLT). Among 1101 patients who underwent LT, 958 patients underwent DDLT, 92 patients underwent LDLT, 45 patients underwent CLKT, and 6 patients underwent DLT. The overall survival (OS) in 1, 5, and 10 years were 89%, 83%, and 82%, respectively. For DDLT, OS in 1, 5, and 10 years were 91%, 84%, and 82%, respectively. For LDLT, OS in 1, 5, and 10 years were 89%, 72%, and 69%, respectively. For CKLT, OS in 1, 5, and 10 years were 90%, 71%, and 71%, respectively. None of the DLT patients died. For DDLT, the factors that affected OS were the presence of fulminant liver failure (odds ratio [OR], 2.23; 95% CI, 1.18-4.18; P=.001), hemodialysis before LT (OR, 2.12; 95% CI, 1.27-3.5; P=.004), retransplant (OR, 4.74; 95% CI, 2.75-8.17; P=.000), and recipient age >60 years (OR, 1.86; 95% CI, 1.27-2.73; P=.001). For hospitalization before LT (due to an acute-on-chronic liver failure), the OR was 2.10 (95% CI, 1.29-3.42; P=.003). Donor intensive care unit time >7 days (OR, 1.46; 95% CI, 1.04-2.06; P=.02) was also associated with overall mortality. We identified prognostic factors in donor-recipient LT matching. Furthermore, we demonstrated that an adequate organ allocation with donor-recipient selection might increase graft survival and reduce waiting list mortality.
