title: Treatment with growth factors in myelodysplastic syndromes.
abstract: In myelodysplastic syndromes (MDS), pancytopenia leads to a high risk of infectious and hemorrhagic complications. The progression to acute myeloid leukemia adds to morbidity and mortality. While transfusions of red blood cells and platelets are still a cornerstone of the therapy, the clinical use of recombinant hematopoietic growth factors has enlarged the range of therapeutic applications in patients with MDS. It is possible to reverse neutropenia by administration of G-CSF (granulocyte colony stimulating factor) or GM-CSF (granulocyte-monocyte colony stimulating factor). In the case of a severe infection, therapeutic administration of G-CSF together with antibiotics might be justified in otherwise neutropenic MDS patients. Since especially patients with only slight impairment of erythropoiesis and no transfusion dependency have the highest response rates but need erythropoietin (EPO) the least, pharmacoeconomic analyses are urgently needed. Controlled randomized trials will have to ascertain wether combinations of EPO with G-CSF or GM-CSF are of benefit. Clinical studies with thrombopoietin (megakaryocyte growth and differentiation factor) have to be initiated to find out whether thrombocytopenia in MDS can be reversed.
