Older patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) who underwent haplo/cord reduced intensity transplantation achieved similar outcomes as their counterparts who received HLA-matched unrelated donor cells, according to a study involving 109 individuals. Participants were ≥50 years of age and had AML or high-risk MDS. Between 2007 and 2013, they received either HLA-matched unrelated donor cells (n=68; MUD) or haplo/cord grafts (n=41), followed by reduced intensity conditioning with fludarabine/melphalan and antibody-mediated T-cell depletion. Among the results:
- 2-year progression-free survival rate was 38% in the group receiving MUD, vs 33% in the haplo/cord transplant contingent.
- Overall survival rates were 48% in each group.
- Graft-versus-host disease-free relapse-free rates were 32% and 34%, respectively.
- Acute grade 2-4 and chronic graft-versus-host-disease rates were similar in both groups.
- There were no outcome differences by donor type.
