AIM: To clarify the risk-benefit point of the Model for End-stage Liver Disease (MELD) score in patients waiting for deceased-donor liver transplantation (DDLT). METHODS: The present study retrospectively investigated 213 patients registered on the waiting list at Kyoto University (Kyoto, Japan) between 2005 and 2016. Patients were stratified by MELD score (6-9/10-14/15-20/21-30/31-40) and classified into two groups: the DDLT group (30 patients) and the waiting group (183 patients). Their post-registration mortality risk and long-term survival were compared. RESULTS: For all MELD categories, the mortality risk was lower in the DDLT group than in the waiting group. The hazard ratio of post-registration mortality decreased in the DDLT group compared to the waiting group as the MELD score increased (0.36/0.12/0.06/0.042/0.004). Survival was significantly better among patients in the DDLT group with a MELD score of 15 or more than among patients in the waiting group. CONCLUSION: For all MELD categories, DDLT reduced the mortality risk of patients on the waiting list.
