The development of less toxic pretransplant conditioning regimens, more effective prophylaxis of graft-versus-host disease (GVHD), improved infection control, and other advances in transplant technology have resulted in a rapidly growing number of transplant recipients surviving long-term free of the disease for which they were transplanted. The changes over decades in the transplant recipient population and in the practice of HCT will have almost inevitably altered the composition of the long-term survivor population over time. Apart from an increasingly older transplant recipient cohort, the pattern of transplant indications has shifted from the 1990s when chronic myeloid leukemia made up a significant proportion of allo-HCT indications. Changes in cell source, donor types, conditioning regimens, GVHD prophylaxis, and supportive care have all occurred, with ongoing reductions in both relapse and non-relapse mortality (NRM) have been demonstrated. .eText ISBN: 9781119612735
