Recombinant human erythropoietin reduces the need for erythrocyte and platelet transfusions in pediatric patients with sarcoma: A randomized, double-blind, placebo-controlled trial

OBJECTIVE: To evaluate the effect of recombinant human erythropoietin (EPO) and iron supplementation on transfusion requirements in pediatric patients with sarcoma who were receiving chemotherapy, we performed a double-blind, placebo-controlled, randomized trial. METHODS: Twenty-four pediatric patients with malignant solid tumors were randomly assigned to receive either placebo (saline solution) or EPO for a 16-week study period. The starting dose was 150 IU/kg per dose three times a week and was escalated by 50 IU/kg per dose increments monthly until packed red blood cell (PRBC) transfusion independence was achieved or a dosage of 300 IU/kg per dose was reached. Iron supplementation was prescribed at a dose of 6 mg of elemental iron per kilogram daily. The primary study end point was the comparison of PRBC transfusion requirements in the two groups. RESULTS: Of 24 patients, 20 were evaluable for response. The median PRBC transfusion requirement during the 16-week period was 23 ml/kg in EPO-treated patients versus 80 ml/kg in placebo patients ( p = 0.02). The median number of single-donor platelet units transfused was zero in the EPO-treated patients compared with four in the placebo group ( p = 0.005). No statistical difference in the intensity of bone marrow suppression was seen, as measured by the median number of complete blood cell counts with an absolute neutrophil count of
