Lenalidomide Is Effective Treatment Option for Patients with Refractory Anemia with Ring Sideroblasts and Thrombocytosis Megan Melody, BA, MS,,Najla Al Ali, M.Sc David A Sallman,

Refractory anemia with ring sideroblasts associated with marked thrombocytosis (RARS-T) is a hematological malignancy that combines features of both a myeloproliferative and myelodysplastic disorder. There have been recent reports of the successful treatment of anemia in 2 patients with RARS-T with lenalidomide.

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.

c) antalet Lenalidomide is efficient in reducing red blood cell transfusion dependency and markedly lowering platelet counts in MDS/MPN-RS-T in the context of major platelet counts. Efficacy of lenalidomide in myelodysplastic/myeloproliferative neoplasms with ring sideroblasts and an extreme platelet count 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 transfusion dependent, with lenalidomide. Background: Myelodysplastic/myeloproliferative neoplasms (MDS/MPN) with ring sideroblasts and thrombosis (MDS/MPN-RS-T), include the dysplastic features of Refractory Anemia with Ring Sideroblasts (RARS) and the myeloproliferative features of essential thrombocythemia (ET) and are characterized by a high rate (50%) of JAK2 V617F mutations or rarely by the presence of mutations in exon 10 of the MPL (myeloproliferative leukemia) gene or in exon 9 of the calreticulin gene. Refractory anemia with ring sideroblasts associated with marked thrombocytosis (RARS-T) is a hematologic malignancy that often results in transfusion dependency and a hypercoagulable state.

However, presence of ringed sideroblasts do not signify clonality, is sometimes reversible, and the percentage of RS do not correlate with prognosis. In the first patient, blood transfusions were initiated for one year, however, due to an increase in dependence on red blood cell transfusions, treatment with lenalidomide (5 mg daily 21/28days) was started and led to a decrease in the platelet count from 686 to 220 G/L associated with an regular improvement in hemoglobin levels from 80 to 100 g/L within the first 28 weeks of lenalidomide (only 6 units of red blood cells were transfused along this period). 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).
