The only potentially curative MDS treatment is hematopoietic stem cell transplantation, which is usually not even discussed because most patients with advanced age at diagnosis. Currently only three drugs are approved by US Food and Drug Administration (FDA) and European Medicines Agency for therapy of MDS. For low and intermediate-1 risk MDS del(5q) the novel immunomodulatory drug lenalidomide is asserted, and for intermediate-2 and high risk the two hypomethylating agents (azacitidine, decitabine) are approved. The results of completed clinical trials demonstrating the efficacy and safety of these agents are presented. The new data indicating that the successful future of MDS treatment rests in the combination of multiple treatments modalities to achieve improved clinical outcomes are discussed in this review.</p></abstract><trans-abstract xml:lang="ru"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>myelodysplastic syndromes</kwd><kwd>hypomethylating agents</kwd><kwd>lenalidomide</kwd><kwd>azacitidine</kwd><kwd>decytabine</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>миелодиспластический синдром</kwd><kwd>леналидомид</kwd><kwd>гипометилирующие агенты</kwd><kwd>азацитидин</kwd><kwd>децитабин</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
