Early epoetin alfa treatment in children with solid tumors

Combination chemotherapy is often used for long periods in children with solid malignancies, leading to anemia and necessitating intervention with red blood cell (RBC) transfusions. Transfusions, however, are associated with a variety of adverse events and risks. Recombinant human erythropoietin (rHuEPO, epoetin alfa) has been shown to reduce the need for transfusions and to ameliorate the symptoms of anemia in adults, but few studies have been conducted thus far in pediatric patients.

Thirty-seven children with solid tumors receiving treatment with platinum- or nonplatinum-based chemotherapy were treated with epoetin alfa and supplemental iron in a single-center, open-label, 28-week, case-control study.

Epoetin alfa significantly reduced the need for RBC (P = 0.007) and platelet (P = 0.01) transfusions, and prolonged the time to first RBC transfusion (P = 0.0004) as compared to the control group. Moreover, epoetin alfa was effective in maintaining mean hemoglobin levels during the course of the study, whereas they declined below baseline after week 9 in the control group.

Epoetin alfa is effective and safe in reducing transfusion requirements and maintaining adequate hemoglobin levels in children with solid tumors undergoing combination chemotherapy.
