Long-term outcomes (beyond 5 years) of liver transplant recipients-A transatlantic multicenter study

The long-term (> 5 y) outcomes following liver transplantation (LT) have not been extensively reported. The aim was to evaluate outcomes of LT recipients who have survived the first 5 years. A multicenter retrospective analysis of prospectively collected data from 3 high volume LT centers (Dallas-USA, Birmingham- UK, and Barcelona-Spain) was undertaken. All adult patients, who underwent LT since the inception of the program to December 31, 2010, and survived at least 5 years since their LT were included. Patient survival was the primary outcome. A total of 3682 patients who survived at least 5 years following LT (long-term survivors) were included. Overall, median age at LT was 52 years (IQR 44-58); 53.1% were males; and 84.6% were Caucasians. A total of 49.4% (n = 1820) died during a follow-up period of 36,828 person-years (mean follow-up 10 y). A total of 80.2% (n = 1460) of all deaths were premature deaths. Age-standardized allcause mortality as compared to general population was 3 times higher for males and 5 times higher for females. On adjusted analysis, besides older recipients and older donors, predictors of long-term mortality were malignancy, cardiovascular disease, and dialysis. Implementation of strategies such as noninvasive cancer screening, minimizing immunosuppression, and intensive primary/secondary cardiovascular prevention could further improve survival.

Automated summary

This study evaluated the long-term outcomes of liver transplant recipients who survived the first 5 years. The study found that the mortality rate was higher for males compared to the general population, as well as for older recipients and donors. Predictors of long-term mortality included malignancy, cardiovascular disease, and dialysis. Implementing strategies such as non-invasive cancer screening and cardiovascular prevention could improve survival.
