title: Prevention of chemotherapy-induced anemia by the use of erythropoietin in patients with primary malignant bone tumors (a double-blind, randomized, phase III study).
abstract: BACKGROUND
  Patients undergoing chemotherapy for treatment of malignancy frequently experience clinically significant anemia. Myelosuppressive chemotherapy impairs erythropoiesis, which may not fully recover between treatment cycles. Recombinant human erythropoietin (rHuEPO) has been effectively introduced in anemic patients suffering from chronic renal failure. The present study was designed to assess, first, whether rHuEPO treatment decreases transfusion requirements in chemotherapy-induced anemia and, second, whether high-dose rHuEPO application is safe.
  
  
  METHODS
  Thirty consecutive anemic patients (hemoglobin <11 g/dl) receiving combination chemotherapy for primary malignant bone tumors were studied in a prospective, double-blind, randomized, Phase III trial. Patients received chemotherapy according to one of two German protocols, depending on histologic diagnosis. All subjects enrolled were randomly assigned either to receive 600 IU of rHuEPO per kg of body weight intravenously twice a week or to receive a placebo during chemotherapy. To obtain comparable data, an observation period of 20 weeks was chosen. Twenty-nine patients fulfilled the criteria and were eligible for statistical evaluation.
  
  
  RESULTS
  Transfusion requirements were significantly decreased from Week 8 of therapy (p<0.05) in the treatment group. Therapeutic benefits were even more evident with continuation of therapy (Week 12, p = 0.03; Week 16, p = 0.016; Week 20, p = 0.002). The blood required was 2.1 units of red cells in the treatment group and 8.4 units of red cells in the placebo group. All patients tolerated rHuEPO with no serious side effects.
  
  
  CONCLUSIONS
  These findings suggest that rHuEPO is an effective and well-tolerated therapeutic option for decreasing the transfusion requirements in chemotherapy-induced anemia.
