  20. 20. Haplo-cord vs MUD: Conclusions • Haplo-cord SCT in high-risk patients offers time to engraftment and survival rates comparable to those seen with myeloablative 8/8 HLA-matched unrelated donor transplantation, with significantly lower GVHD rates • In contrast to previous comparative studies including single CB transplantations, the Haplo-cord approach offers similar NRM rates as MUD transplantation • Haplo-cord SCT provides a valuable option for high-risk patients who lack a matched adult donor or who require urgent transplantation • Thus, this CB transplantation approach merits broader evaluation

  31. 31. Conclusions: Haplo-cord SCT • Provides a prompt myeloid reconstitution even using CB units with relatively low cell content • CB should be considered as a front line option for patients in need of an allogeneic SCT, especially for patients with acute leukemia • May allow the reduction of cell dose requirements, expanding CB availability and facilitating selection on the basis of HLA match (especially relevant for uncommon haplotypes, CCR5 mutation in HIV+ patients) • Efforts to improve immune reconstitution should continue since post-engraftment infections remain an issue
