Haploidentical Stem Cell Transplantation Using Post-Transplant Cyclophosphamide

Historically, the best results of allogeneic SCT have been obtained when the stem cell donor is a human leukocyte antigen (HLA)-matched sibling, however, this is only available for approximately 30 percent of patients in need for SCT. Alternative donor sources include matched unrelated donor utilizing the donor registry, cord blood transplant and mismatched donor transplant. A human leukocyte antigen (HLA)-haploidentical donor is one who shares, by common inheritance, exactly one HLA haplotype with the recipient, and includes the biologic parents, biologic children and full or half siblings. There is strong body of evidence supporting the use of haplo-SCT in patient who lack a matched sibling or unrelated donor with high rates of successful engraftment, effective Graft Versus Host Disease (GVHD) control and favorable outcomes comparative to those seen using other allograft sources, including HLA-matched sibling SCT. Furthermore, it provides a cost-efficient donor option in a timely manner especially for patients who need to proceed quickly to transplant due to concern of disease relapse/progression.
