Abstract
Comparative studies between total body irradiation (TBI)-based and busulfan-based myeloablative conditioning (MAC) regimens for cord blood transplantation (CBT) have been limited. We retrospectively analyzed the results of single-unit CBT in 333 adult patients who received either TBI-based (n = 258) or busulfan-based (n = 75) MAC regimens at our institute. After adjusting for significant variables in the univariate analysis, there were no significant differences in neutrophil recovery (hazard ratio (HR), 0.88; p = .460), grade III-IV acute graft-versus-host disease (GVHD) (HR: 1.40, p = .410), extensive chronic GVHD (HR: 0.73, p = .380), relapse (HR: 0.61, p = .270), non-relapse mortality (HR: 1.38, p = .420), overall survival (HR: 1.18, p = .637), or event-free survival (HR: 1.08, p = .773), although platelet recovery was lower with marginal significance for the busulfan-based regimen (HR: 0.67, p = .068). In subgroup analysis, TBI-based regimens were superior to busulfan-based regimens in terms of survival for acute lymphoblastic leukemia, but not for myeloid malignancies. Further investigation is warranted even for CBT.

A novel reduced-intensity umbilical cord blood transplantation using a recombinant G-CSF combined with high-dose Ara-C for active myeloid malignancies. Bone Marrow Transplant 2014; 49:955-60. [PMID: 24732960 DOI: 10.1038/bmt.2014.66] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2014] [Revised: 02/19/2014] [Accepted: 02/20/2014] [Indexed: 02/03/2023]
Abstract
Non-remitting patients with hematologic myeloid malignancies have poor prognosis. To overcome this problem, we investigated the use of reduced-intensity preconditioning umbilical cord blood transplantation (RICBT) combined with recombinant G-CSF (rG-CSF) with high-dose Ara-C, fludarabine, melphalan, and 4 Gy of TBI in a phase I/II study in patients with non-remitting myeloid hematologic malignancies. Thirteen patients were enrolled, including 12 with non-remitting AML and one patient with blastic crisis CML (CML-BC). The patients' median age was 45 years, with a median comorbidity index of 4. All patients received 4/6 serological HLA-antigen matched unrelated umbilical cord blood. All patients were engrafted within 30 days after RICBT (median, 20 days; range, 14-29) and achieved complete remission without prior hematopoiesis. Common grade III non-hematologic toxicities included eight cases of transient mucositis (62%) and six cases of febrile neutropenia (46%). Transplant-related mortality was 7.7%. The 1-year overall survival was 28.6% in cases without post-RICBT treatment and 83.3% in cases with post-RICBT treatment. These data suggest that in active AML and CML-BC, the combination of rG-CSF with high-dose Ara-C and fludarabine/melphalan/4 Gy TBI with a reduced-intensity preconditioning regimen is well tolerated, secures engraftment and has significant anti-leukemia activity. In addition, performing post-RICBT treatment may provide high-quality long-term survival and remission.

Abstract
Growing evidence supports the efficacy of cord blood transplantation (CBT) to treat patients with haematological malignancies, and the number of CBTs is rapidly increasing. Herein, we review considerations regarding conditioning regimens for CBT, the impact of double unit transplantation on CBT outcomes, and data regarding infectious complications following CBT.

Abstract
PURPOSE OF REVIEW To review the available data on the outcomes of pediatric and adult patients with acute myeloid leukemia, myelodysplastic syndrome and chronic myelogenous leukemia after umbilical cord blood transplantation. RECENT FINDINGS The literature shows that after umbilical cord blood transplantation the relapse rate, disease-free survival and overall survival of patients with myeloid malignancies is similar to other hematopoietic stem cells sources. Disease status at the time of transplantation is found in several studies to be a very important determinant of long-term outcome. Newer strategies such as double umbilical cord blood transplant and utilization of nonmyeloblative conditioning regimens show promising results. SUMMARY Umbilical cord blood is a valuable alternative source of hematopoietic stem cells for transplantation of patients with myeloid malignancies who need an allogeneic transplant, but lack a suitable sibling donor.

Abstract
Cord blood is currently used as an alternative to bone marrow as a source of stem cells for hematopoietic reconstitution after ablation. It is also under intense preclinical investigation for a variety of indications ranging from stroke, to limb ischemia, to myocardial regeneration. A major drawback in the current use of cord blood is that substantial morbidity and mortality are associated with pre-transplant ablation of the recipient hematopoietic system. Here we raise the possibility that due to unique immunological properties of both the stem cell and non-stem cell components of cord blood, it may be possible to utilize allogeneic cells for regenerative applications without needing to fully compromise the recipient immune system. Issues raised will include: graft versus host potential, the immunogenicity of the cord blood graft, and the parallels between cord blood transplantation and fetal to maternal trafficking. The previous use of unmatched cord blood in absence of any immune ablation, as well as potential steps for widespread clinical implementation of allogeneic cord blood grafts will also be discussed.
