[Allogeneic stem cell transplantation]

Over the last two decades, four major therapeutic approaches have dramatically changed the prognosis in chronic myelogenous leukemia(CML). Those include allogeneic stem cell transplantation, interferon-alpha based regimen, donor-leukocyte infusions, and the revolutionary BCR/ABL tyrosine kinase inhibitor such as STI571. Each modality has exploited and targeted different aspects of CML biology, and is associated with different risk-benefit ratios. In this section, we update the results of both related and unrelated donor transplantation, donor lymphocyte infusions, and non-myeloablative stem cell transplantation in CML in comparison with the other treatment modalities.
