Abstract

Pegfilgrastim has equivalent efficacy to daily G-CSF in enhancing neutrophil recovery after chemotherapy, but conclusive data concerning its use for peripheral blood stem cell (PBSC) mobilization are lacking. From 2003 to 2008 we used high-dose chemotherapy in 64 lymphoma patients. At mobilization chemotherapy (ESHAP) the first 26 patients used unconjugated G-CSF, while the remaining 38 patients received Pegfilgrastim. At the time of harvest 25 patients collected stem cells after the use of G-CSF and 36 in the Peg group. No statistical by significant differences were observed in median peripheral CD34+ cells mobilized (77μL versus 71μL) and in collected PBSC (12.3×106/kg versus 9.4×106/kg p=0.76). In the PEG group all patients collected the target PBSC with a single apheresis with a greater proportion of " optimal" mobilizers (83% versus 64%; p=0.05). In conclusion a single dose of Pegfilgrastim could be a valid alternative to unconjugated G-CSF to mobilize PBSC in lymphoma patients.
