Review of conditioning regimens for haplo-identical donor transplants using post-transplant cyclophosphamide in recipients of G-CSF mobilised peripheral stem cell

Haplo-identical transplant is being increasingly used in patients who do not have a readily available matched related or unrelated donor. Post-transplant cyclophosphamide's use due to its simplicity and documented efficacy has made this approach readily employable across diverse transplant centres across the globe. The outcomes of regimens used for conditioning in recipients of bone marrow are at times in variance to that from more commonly employed G-CSF mobilised peripheral stem cell (PBSC). This review highlights various conditioning regimens used in PBSC recipients, with emphasis on toxicities, practicalities and transplant related outcomes of relapse, non-relapse mortality and graft versus host disease.
