Sideroblastic anemia (SA) includes a group of inherited and acquired anemias of ineffective erythropoiesis characterized by an accumulation of ring sideroblasts (RS) in the bone marrow and decreased production of mature red blood cells. 1 Ring sideroblasts are nucleated erythroblasts with a pathologic accumulation of iron granules in the mitochondrial matrix.

Median time from diagnosis to treatment was 12.4 months (range 2.1-47.4). Median number of prior therapies was 1 (range 0-3). Three patients received lenalidomide frontline therapy. Overall, 3/7 patients (43%) responded to lenalidomide therapy. Four patients were red cell transfusion dependent at the time of lenalidomide initiation.

Foster School of Lenalidomide is active against several hematologic malignancies, including lower-risk MDS with or without the 5q− cytogenetic abnormality. 15-17 Clinical trials using 10 mg lenalidomide have reported cytogenetic responses of 44% and 10%, respectively, in MDS with or without 5q−.

CONTEXT AND OBJECTIVE: Refractory anemia with ring sideroblasts and thrombocytosis (RARS-T) is a provisional entity included in the MDS/MPN overlap syndromes with features of refractory anemia with ring sideroblasts (RARS) and thrombocytosis (platelet count 450 x 10/L). 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.
