Y1 - 2018/1/1 §Ring sideroblasts ≥ 15% were present in 142 (71.7%) of 198 sequenced patients with gene mutation data (see text for SF3B1 gene mutation incidence). RBC Transfusion Independence The proportion of patients who achieved RBC-TI ≥ 8 weeks was significantly higher in the lenalidomide group (26.9%) than in the placebo group (2.5%; Fisher exact P < .001; Table 2 ). 2016-01-01 · The accurate classification of 5q minus syndrome with a JAK2 V617F mutation is yet not determined, especially in patients with additional presence of ring sideroblasts. The case described above responded well to the treatment with lenalidomide, which is commonly seen in patients with isolated 5q minus deletion MDS but much less often in patients with other types of low grade MDS [9] , [13] . 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.

Author information: (1)Department of Medicine, Texas Tech University Health Sciences Center Paul L. 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−. 16,17 This suggests that lenalidomide can eliminate to certain degree the abnormal MDS clone.

There have been recent reports of the successful treatment of anemia in 2 patients with RARS-T with lenalidomide. Patient has ring sideroblasts < 15%; AND Used in combination with an erythropoiesis-stimulating agent [ESA] (i.e., epoetin alfa, darbepoetin alfa) following no response or loss of response to an ESA alone; OR Patient has ring sideroblasts ≥15%; AND Patient failed therapy with an ESA and a granulocyte-colony stimulating (HealthDay)—Lenalidomide produces hematologic responses in myelodysplastic syndrome (MDS)/myeloproliferative neoplasm (MPN) with ring sideroblasts (RS) and thrombocytosis (MDS/MPN-RS-T 2021-03-23 · 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 2020-01-08 · Among the study population of regularly transfused (median 5 units over 8 weeks) lower-risk MDS patients with ring-sideroblasts, 95% had previously received ESAs. Key findings included: The primary endpoint of transfusion independence over 8 weeks during weeks 1 to 24 of the study was met in 38% of luspatercept-treated patients compared with 13% in the placebo arm ( P <0.001).
