Normally, sideroblasts are present in the bone marrow, and enter the circulation after maturing into a normal erythrocyte. The presence of sideroblasts per se does not define sideroblastic anemia. Only the finding of ring (or ringed) sideroblasts characterizes sideroblastic anemia.

It can take 4 or more cycles to know if this drug is working for you. Most MDS patients who respond to lenalidomide do so for 1 or 2 cycles (1 to 2 months).

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.

AU - Patnaik, Mrinal M. PY - 2018/1/1. 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.

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.

Blood. 2010; 116(2):180-2 (ISSN: 1528-0020) 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.
