Carboplatin associated anemia treated with subcutaneous erythropoietin - a pilot-study.

ABSTRACT

In nineteen patients with carboplatin-induced anemia (hemoglobin less than 90 g/l), recombinant human erythropoietin was administered subcutaneously three times a week on an outpatient basis. The initial dose was 50 Units/kg of body weight. If response was not achieved within 3 weeks, dose was increased to 75 Units/kg. Using the same criteria further escalations to 100 and 150 Units/kg were performed. If there was no response erythropoietin was terminated. Two patients obtained an increase of hemoglobin levels greater than 100 g/l, which was considered as a clinical response in this study, with a dose of 75 U/kg; eleven patients needed an erythropoietin dose of 100 U/kg and three a dose of 150 U/kg. The other three patients required hemotransfusions and were considered non responders. Hemoglobin increases occurred despite continuation of carboplatin chemotherapy. In conclusion, subcutaneous eryhtropoietin is effective and safe in the treatment of carboplatin-induced anemia.
