Abstract:
To analyze the unpredicted event of hematological improvement (HI) during iron-chelation therapy (ICT), we reviewed a series of 53 myelodysplastic patients with transfusion dependency in a retrospective study involving 8 centers afferent to the “Rete Ematologica Lombarda”. According to the IWG response criteria published in the year 2000, we observed erythroid responses in 19 patients (35.1%), 5 major (9.2%) and 14 minor (25.9%). In the assessable patients, platelet response was 8/13 (61%) and neutrophil response was 13/17 (76.4%). Only in patients with erythroid improvement, multilineage responses were observed. Apparently, patients with greater erythropoiesis dysfunction may take more advantage.
