[Current approaches of treatment for myelodysplastic syndrome (MDS)].
The number of treatment modalities for patients with myelodysplastic syndromes (MDS) has increased, but curative options are still limited. For the majority of patients with low risk there is no standard therapy other than appropriate supportive care. In selected patients anabolic steroids, differentiation inducers such as cis-retinoic acid (RA), interferon alpha or gamma have been claimed to be active. Application of growth factors such as granulocyte-macrophage colony stimulating factor (GM-CSF), granulocyte colony stimulating factor (G-CSF), and interleukin 3 (IL-3) improves neutrophil count and diminishes frequency of infectious complications, but responses are incomplete and of short duration. Preliminary results of erythropoietin (Epo) applied in therapeutical doses are disappointing, giving an improvement in 15-20% patients. Epo in large doses produces greater and sustained responses, but this treatment is too expensive. Low-dose cytosine arabinoside (Ara-C) induces a response rate in 25-30% patients, however, no survival advantage has been obtained. Addition of RA or GM-CSF produces response rates comparable to Ara-C alone, but also with no prolongation in survival. Bone marrow transplantation (BMT) offers a good chance of long-term disease-free survival if is performed in an early stage of the disease or in complete remission, however, it is limited to patients below 55 years with an HLA-identical donor. Relatively young, high risk patients not eligible for allogeneic BMT should be considered for treatment with intensive polychemotherapy.
