*Purpose: The inherent risk of livers from donors after circulatory death (DCD) is well known such as primary non-function (PNF) and increased rates of biliary complications. Due to the high graft dysfunction rate in a relatively early phase after the initial liver transplant (LT), many patients who received DCD organ needs re-transplant and were re-listed. However, the clinical characteristics and prognostic factors of those re-listed patients have not been fully elucidated.
*Methods: Adult patients who received DCD LT between 2002 and 2019 were identified from the UNOS database. Predictors of drop out due to too sick/death in re-listed patients were examined using Fine-Gray model. Predictors of overall survival (OS) after re-LT were examined using Cox regression model.
*Results: Among 5734 patients, 1332 patients died without re-listing (23.2%) and 712 patients were re-listed after initial LT (12.4%). Among 711 re-listed patients, 480 patients received second LT (8.4%) and 128 patients were removed from list because of too sick/death (2.2%). Among 480 re-LT patients, 187 patients (39.0%) died after re-LT. The median days between first LT and re-listing was 99 days (IQR: 12-331). The distribution of initial graft lost causes/percentage of re-LT patients/median waiting time form re-listing are summarized (Table). In re-listed patients, older recipient (> 50) and graft loss caused by primary non-function or HAT/PVT were predictors of dropout. In re-LT patients, younger recipient (≤50) at first-LT, male, lower MELD at time of second-LT, and younger donor age were favorable factors of patient survival after LT. The OS from first-LT was compared according to recipient age in patients who were re-listed and not re-listed. The 5-years survival rate in younger patients was 5.0% better in patient without re-listing, which was much higher in re-listed patients (14.9%) (Figure).
*Conclusions: Nearly 10% of DCD LT patients received re-LT mainly due to complications related to DCD organs. Younger recipient age is an important factor to survive in case patients need re-listing after LT using DCD organ.
