Abstract:
Despite a remarkable increase of deceased donors, organ shortage is the main hurdle of organ transplantation in Korea. Therefore, liver transplantation priority is a major issue of liver allocation. We confront a situation that needs to change in order to achieve more adequate and objective allocation of the system. We considered the MELD system as an alternative to the CTP score and Status system. For application of the MELD system, comparison between two systems is required; and a national-based retrospective review of liver transplantation candidates (waiting list) was conducted as a multi-center collaborative study. Eleven transplant centers participated in this national study. From 2009 to 2012, 2,702 waiting lists were enrolled. After mean 349+/-412 days follow-up, 967 patients (35.8%) of liver transplantation, 750 patients (27.8%) of drop-out/mortality, and 719 patients (26.6%) on waiting were identified. In analysis of patient mortality during waiting time, status system showed significant difference of waiting mortality by status at registration. However, differences of waiting mortality by MELD system were more prominent and discriminate. In comparisons by MELD score in exclusive Status 2A waiting patients, there was a significant difference of waiting mortality by MELD score. This means that the MELD system is a good predictor of short-term survival after listing compared with status system with CTP score. Korean national-based retrospective study showed the superiority of the MELD system in prediction of short-term mortality and usefulness as a determinant for allocation priority.
