Quality of life, physical function and MRI T2*in elderly low-risk MDS patients treated to a haemoglobin level of andgt;= 120 g/L with darbepoetin alfa +/- filgrastim or erythrocyte transfusions

• Objective: Anaemia in low-risk myelodysplastic syndromes (MDS) is associated with reduced quality of life (QoL). Response to treatment with erythropoietin +/- granulocyte colony-stimulating factor (G-CSF) is associated with improved QoL, but whether transfusion therapy with higher haemoglobin (Hb) target levels has similar effects is unknown. The objective for this prospective phase II Nordic multicentre trial was to assess QoL, response rate and physical function in elderly anaemic MDS patients treated to a target Hb level of andgt; 120 g /L. Methods: Thirty-six elderly patients with low-and intermediate-1 risk MDS received darbepoetin (DA) 300 mu g/wk, with the addition of G-CSF if no response. If the Hb target was reached at 16 wk, treatment was maintained until week 26. Remaining patients were transfused to reach the target level for at least 8 wk. Results: Twenty-seven patients completed the study. Response rate to DA +/- G-CSF was 67% in evaluable patients and 56% according to intention to treat. Eighteen patients reached the target Hb level according to protocol. QoL scores for fatigue, dyspnoea, constipation, and physical, role and social functioning improved significantly during study, with similar results for transfused and untransfused patients. Maintaining Hb andgt; 120 g /L did not confer a higher transfusion rate, once the target was reached. In two of fourteen patients, magnetic resonance imaging T2* indicated cardiac iron overload, however, without association with ferritin levels. Conclusions: In elderly anaemic MDS patients, an increment in haemoglobin is associated with improved QoL, whether induced by growth factor treatment or transfusion therapy.
