Background: The aim of this study was to assess improvements in long-term survival of pediatric patients after liver transplantation by analyzing outcomes in transplant recipients who survived beyond 1 year after transplantation. There has been a marked increase in the 1-year survival of pediatric patients, from 78% in transplant recipients between 1987 and 1990 to 95% in transplant recipients between 2011 and 2017. The long-term outcomes have not seen a similar trend, creating a disparity that warrants analysis., Methods: We analyzed 13 753 pediatric patients who survived for 1 year after receiving orthotopic liver transplantation between 1987 and 2017. The study period was divided into six eras. Outcomes were analyzed using the Kaplan-Meier method for time-to-event analysis, and multivariable Cox regression., Results: There were no significant gains in long-term outcomes among 1-year survivors over the past three decades. Log-rank tests for equality of survivor functions between each era and 1987-1990 were not statistically significant. Cause of death analysis revealed that although infections caused 20.6% of deaths in patients transplanted between 1987 and 1990, this number dropped to 5.6% in those transplanted between 2011 and 2017 (p = .01). Malignancy caused 10.6% of deaths in 1987-1990 but caused 22.2% of the deaths in 2011-2017 (p = .04)., Conclusion: Despite the gratifying gains in short-term survival of pediatric patients, 1-year survivors have no significant improvements in long-term survival after undergoing a liver transplantation. Long-term sequelae of immunosuppression, such as malignancy and infection, continue to be the most common causes of death. This study highlights the necessity for better long-term management of immunosuppression., (© 2021 Wiley Periodicals LLC.)
