Second allogeneic transplantation for myeloid malignancies is feasible for a group of patients.
Active disease and time from first transplantation (<430 days) are associated to a poor outcome
Using a different donor at second allogeneic transplantation did not appear to change outcome
The use of an HLA-identical sibling donor at second allogeneic hematopoietic cell transplantation appears to be associated with better survival
