Improvement in survival of acute myeloid leukemia and myelodysplastic syndrome patients following allogeneic transplant: a long-term institutional experience

BackgroundAllogeneic stem cell transplant (allo-SCT) plays a key role in the treatment of patients with both acute myeloid leukemia (AML) and myelodysplastic (MDS). Outcomes of allo-SCT have improved with optimization of transplant practices. We sought to evaluate trends in survival in AML and MDS patients undergoing allo-SCT at our institution from 1984 to 2018.MethodsA retrospective analysis of 900 consecutive AML and MDS patients undergoing allo-SCT was performed. Patients were divided by year of transplant for analysis. Primary endpoints were progression free survival (PFS) and overall survival (OS). Secondary endpoints included non-relapse mortality (NRM), graft-versus-host disease (GVHD), GVHD-free relapse free survival (GRFS), and transplant complications.ResultsWe found a significant improvement in survival from 1984 to 2018 with 5-year PFS and OS improving from 17% to 49% and 17% to 53%, respectively (statistically significant difference since 2004; p
