Abstract
PURPOSE: The aim of the study was to evaluate whether glycosylated granulocyte colony-stimulating factor (G-CSF) (lenograstim) offers a benefit over non-glycosylated G-CSF (filgrastim) in clinically relevant end points after high-dose chemotherapy (HDC) and autologous peripheral blood stem cell transplantation (PBSCT). METHODS: We retrospectively analyzed the outcome of 261 patients treated with either lenograstim (n=68) or filgrastim (n=193). Time to blood cell recovery, toxicities, and infectious complications were analyzed in a total of 469 G-CSF treatment cycles. RESULTS: Mean time to leukocyte recovery was 10.7 days (SD+/-0.9) (lenograstim) and 10.8 days (SD+/-0.6) (filgrastim), respectively. Likewise, time to thrombocyte engraftment, febrile days, duration of therapeutic antibiotic treatment, severity of non-hematological toxicities, duration of in-hospital stay, and duration of G-CSF treatment were similar in both groups. Owing to the physicochemical and pharmacokinetic properties of lenograstim, the required dose until leukocyte recovery was significantly smaller as compared to filgrastim (38.5 vs 54.0 microg/kg of body weight). CONCLUSIONS: Collectively, our data indicate that both G-CSF preparations are equally effective in hastening leukocyte recovery in the setting of high-dose chemotherapy followed by autologous PBSCT.
