Summary
Peripheral blood stem cells are increasingly used for allogeneic transplantation. While associated with more chronic graft-versus-host disease, adults show improved survival with G-CSF-mobilized peripheral blood allografts.
Area of Science:
- Hematology
- Transplantation Immunology
Background:
- Peripheral blood stem cells are standard for autografting.
- The optimal stem cell source for allografting remains debated, with comparisons between bone marrow and G-CSF-mobilized peripheral blood.
Purpose of the Study:
- To evaluate the outcomes of G-CSF-mobilized peripheral blood versus unstimulated bone marrow for allogeneic transplantation.
- To assess the impact on graft-versus-host disease and survival in sibling allograft recipients.
Main Methods:
- Review of randomized studies comparing unstimulated bone marrow with G-CSF-mobilized peripheral blood in sibling allogeneic transplantation.
- Analysis of graft-versus-host disease incidence and patient survival.
Main Results:
- A trend towards more chronic graft-versus-host disease was observed with peripheral blood stem cells.
- Adult recipients of G-CSF-mobilized peripheral blood allografts showed improved disease-free or overall survival.
- The impact on acute graft-versus-host disease remains uncertain.
Conclusions:
- G-CSF-mobilized peripheral blood may offer survival benefits for adults undergoing sibling allografting.
- Further research is needed to clarify risks of acute graft-versus-host disease and benefits in pediatric or unrelated donor settings.
