Optimizing Unrelated Donor Cord Blood Transplantation

In contrast to the very high transplant-related mortality (TRM) associated with the early experience of cord blood (CB) transplantation (CBT), recent transplant series have been associated with comparable survival to that of human leucocyte antigen (HLA)-matched unrelated donor transplantation in children with similarly promising results in adults. Consequently, the use of CB as an alternative stem cell source and the global inventory of units in public banks are rapidly increasing although challenges remain. This review will address efforts to optimize CBT from 3 different perspectives: that of the transplant center, the CBT registry, and the CB bank.
