Myelodysplastic syndromes (MDS) are neoplastic diseases of the hematopoietic stem cells, caused by genetic mutations. The clinical courses of MDS are highly variable based on the underlying genetic aberrations, ranging from slowly progressing cytopenia to rapidly-manifesting fatal diseases, including the development of acute myelogenous leukemia. The management of lower-risk MDS, which is risk-stratified based on the revised International Prognostic Scoring System (IPSS-R), mainly consists of a supportive therapy, including blood transfusion to treat anemia and thrombocytopenia. Recently, three novel drugs were approved, which became available in Japan. These include darbepoetin alfa, an erythropoiesis-stimulating agent; lenalidomide, which is specifically active for anemia of 5q- syndrome; and deferasirox, an oral iron-chelating agent. Decision analyses also provide evidence in determining the optimal timing for the potentially curative allogeneic hematopoietic stem cell transplantation for lower-risk MDS. Thus, the management of lower-risk MDS should be optimized using these novel agents and newly available evidence.
