Bone marrow transplantation for hemoglobinopathies
1University of California at San Francisco, USA.
In patients with hemoglobinopathy who are treated by allogeneic matched sibling bone marrow transplantation before the onset of disease-associated organ damage, long term, disease-free survival currently stands at approximately 90%, and transplant-associated mortality is 5% or less. Less toxic nonmyeloablative conditioning regimens that have the potential to reduce procedure-related mortality to even lower levels are under active investigation. Expansion of the donor pool by use of unrelated matched donors awaits improvement in HLA-typing methodology.
