Official Title: Hematopoietic Stem Cell Transplantation Using Alternate Donor Umbilical Cord Blood Options
Brief Summary: This study will determine the safety and applicability of experimental forms of umbilical cord blood (UCB) transplantation for patients with high risk hematologic malignancies who might benefit from a hematopoietic stem cell transplant (HSCT) but who do not have a standard donor option (no available HLA-matched related donor (MRD), HLA-matched unrelated donor (MUD)), or single UCB unit with adequate cell number and HLA-match).
