title: Donor lymphocyte infusions for post-transplant relapse of refractory anemia with excess blasts and monosomy 7.
abstract: An 8-year-old male relapsed with refractory anemia with excess blasts (RAEB) and monosomy 7 and mixed chimerism (MC) 21 months after HLA-matched unrelated donor bone marrow transplant (BMT). He received three donor lymphocyte infusions (DLI) using an escalating dose schedule. He developed grade II acute graft-versus-host disease (GVHD) 9 days after the third DLI, but continued to deteriorate for 2 months with decreasing marrow cellularity but persisting blasts, MC, and monosomy 7, before exhibiting a delayed but complete response which has persisted for 5 years. This case suggests that DLI and graft-versus-myelodysplasia (GVMDS) may be beneficial in post-transplant relapse of pediatric myelodysplasia.
