Recently, several groups have begun to administer granulocyte colony-stimul
ating factor (G-CSF), a hematopoietic growth factor, with or without dexame
thasone to mobilize peripheral blood neutrophils. Granulocyte colony-stimul
ating factor (600 mu g subcutaneously) and dexamethasone (8 mg orally) give
n 12 hours before standard leukapheresis routinely results in the collectio
n of approximately 80 x 10(9) granulocytes. This number of cells is suffici
ent to increase the neutrophil count of a severely neutropenic patient to n
ormal and restore the recipients' ability to develop a neutrophil response
in tissues. Several trials are ongoing to establish the clinical benefit of
this new approach to supportive care for neutropenic patients. Curr Opin P
