Allogeneic peripheral blood stem cell collection as of 2008

The rapid growth of the use of recombinant human granulocyte colony-stimulating factor (rhG-CSF) to mobilize and collect allogeneic peripheral blood stem cells (PBSCs) for transplantation has made it a new international standard. While the procedure remains safe, older donors, donors with significant comorbidities and pediatric donors are now often employed. This brings a new set of challenges in the donor evaluation, medical clearance, informed consent and collection process. Rare and unexpected severe adverse events related to rhG-CSF administration and PBSC apheresis have been described. Proper PBSC donor counseling, evaluation and care have become even more important.
