Individual case reports suggested lenalidomide may be effective in treating RARS-T. In non-del 5q, low-risk Recently described SF3B1 mutations appear to be associated with myeloid neoplasms with ring sideroblasts [4, 5]. Lenalidomide is an immunomodulatory thalidomide analogue (IMiD) that has been shown to have some efficacy in the treatment of anemia in other myelodysplastic syndromes [6, 7], particularly when associated with deletions of chromosome 5q, where transfusion independence occurs in some two-thirds of patients . Patients with refractory anemia with ring sideroblasts and thrombocytosis (RARS-T) are difficult to treat because the cytoreductive treatment might be beneficial for the thrombocytosis component but harmful for the RARS component. As lenalidomide has shown to be efficacious in both myelodysplastic syndromes and myeloproliferative neoplasms, we have treated 2 RARS-T patients, who were Lenalidomide is Effective Treatment Option for Patients with Refractory Anemia with Ring Sideroblasts and Thrombocytosis Megan Melody ,1,2 Najla Al Alu,1 David Sallman,1 Eric Padron,1 Alan List,1 Jeffery Lancet,1 Rami Komrokji1 1H.
