Advances in Treatment of Transfusion-dependent Lower-risk Myelodysplastic Syndromes

At present, the patients with transfusion-dependent lower-risk myelodysplastic syndromes (MDS) have limited treatment options when erythropoiesis-stimulating agent is ineffective or relapsed. With more understanding of the pathological and molecular genetics characteristics of MDS, the development of precise medical treatment of MDS has been promoted. Small-molecule inhibitors, such as transforming growth factor β inhibiter, telomerase inhibiter and hypoxia-inducible factor prolyl hydroxylase inhibitor, provide novel therapeutic strategies for patients. This article reviews the treatment of transfusion-dependent lower-risk MDS patients and discusses the latest clinical research and development of novel targeted agents.
