Potential of dendritic-cell immunotherapy for relapse after allogeneic hematopoietic stem cell transplantation, shown by WT1 peptide- and keyhole-limpet-hemocyanin-pulsed, donor-derived dendritic-cell vaccine for acute myeloid leukemia

Am J Hematol. 2008 Apr;83(4):315-7. doi: 10.1002/ajh.21127.


Induction of leukemia-specific immune responses is a promising treatment for acute myeloid leukemia. A 58-year-old woman received Wilms' tumor 1 (WT1) peptide- and keyhole limpet hemocyanin (KLH)-pulsed, donor-derived dendritic cell (DC) vaccination for AML relapse after allogeneic stem cell transplantation. The vaccination induced immune responses to the naive antigen KLH, whereas definitive immune responses to WT1 were not detected. Leukemia gradually progressed despite of vaccination. This study indicates that DC vaccination can induce an antigen-specific immune response in a patient after allogeneic stem cell transplantation, thus representing a viable strategy to induce antigen-specific immune responses in such patients.
