title: Comparative effect of 100 versus 250 micrograms/m2/day of G-CSF in pediatric patients with neutropenia induced by chemotherapy.
abstract: In pediatric patients with various malignancies, the effect of two different doses of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on chemotherapy-induced neutropenia was examined. Each patient was treated with two courses of the same chemotherapeutic regimen. Following each course, either 100 micrograms/m2 or 250 micrograms/m2 of rhG-CSF was infused daily starting 48 hours after the cessation of chemotherapy and continuing for 14 consecutive days. A total of 29 patients (34 cycles of therapy) were eligible for the study. Both the duration of neutropenia (< 0.5 x 10(9)/l) and median days from the nadir of neutrophils to recovery, > 0.5 x 10(9)/l, were significantly shorter when 250 micrograms/m2 was given. Moreover, the nadir counts of neutrophils and the duration of fever with neutropenia were, although not significant, in favor of 250 micrograms/m2 administration. No differences were observed in the frequency and severity of side effects.
