Pegfilgrastim in pediatric cancer patients

Chemotherapy-induced neutropenia is a major dose-limiting side effect of intensive chemotherapy in cancer patients. Recently, pegfilgrastim (a product with a long half-life, resulting in once-per-cycle dosage) was introduced to prevent neutropenia in adults. The authors report 32 episodes of pegfilgrastim use in seven pediatric cancer patients to diminish chemotherapy-induced neutropenia. Feasibility was assessed by adherence to treatment protocol and safety was assessed by adverse effects. There were only two treatment delays (6%) due to neutropenia. No short-term adverse effects were recorded. The use of pegfilgrastim is feasible in pediatric cancer patients, without short-term adverse effects or major treatment delay due to neutropenia.
