title: Allogeneic and autologous stem cell transplantation in myelodysplastic syndromes.
abstract: Allogeneic bone marrow transplantation is the only currently available curative treatment for myelodysplastic syndromes (MDSs) but can be used only in the minority of patients (10%) who are younger than 55 years or so and for whom an HLA-identical donor is available. Each year in Europe, about 100 patients with MDSs receive an autologous bone marrow transplant. This procedure is usually indicated as first-line treatment, except in patients without excess of blasts or complex cytogenetic abnormalities. In forms with excess of blasts, chemotherapy prior to bone marrow transplantation deserves discussion. Autologous bone marrow transplants or the more recent technique involving transplantation of autologous peripheral stem cells can be considered in patients who have achieved a complete remission under aggressive chemotherapy. This method has been followed by higher recurrence rates in patients with MDSs than in those with de novo acute myeloblastic leukemia, and randomized studies are under way to compare it with aggressive maintenance chemotherapy.
