40-year trends in late mortality and life expectancy after allogeneic blood or marrow transplantation

A retrospective cohort study of 4741 patients who lived 2 or more years after allogeneic blood or marrow transplantation between 1974 and 2014, with follow-up to 2020, found that late mortality among recipients of of alloBMT has decreased over the past 40 years; however, life expectancy was not restored to expected rates compared with the general population. Furthermore, the reduction in risk of late mortality was confined to those who underwent transplantation at a younger age or those who received bone marrow.
