Case in brief
A patient with adverse-risk acute myeloid leukemia (AML) and near-homozygous HLA haplotypes underwent double units unrelated umbilical cord blood transplantation (dUCBT) twice. After molecular relapses at one and two years post-first transplant, complete remission was achieved with venetoclax and azacitidine. A second transplant was performed after a hematologic relapse three years later, leading to clinical stability for one year without graft-versus-host disease.
Diagnostic / clinical pearl
This case illustrates the feasibility of a second umbilical cord blood transplantation in relapsed adverse-risk AML patients with near-homozygous HLA haplotypes.
