Inclusion criteria

  • Age 22 - 50 years

  • Patients will have one of the following hematological malignancies:

    • Acute myelogenous leukemia (AML): Complete first remission (CR1) at high risk for relapse or Complete second remission (CR2)
    • Acute lymphoblastic leukemia (ALL): Complete first remission (CR1) at high risk for relapse or Complete second remission (CR2)
    • Acute undifferentiated leukemia (AUL) or biphenotypic leukemia: CR1 or CR2
    • Myelodysplastic Syndrome (MDS) with one of the following: Low and Intermediate-1 International Prognostic Scoring System (IPSS) score with Life-threatening neutropenia or thrombocytopenia; or Platelet transfusion dependence Intermediate-2 or High IPSS score Therapy-related disease: patient with history of chemotherapy and current evidence of MDS
  • Patients with adequate organ function and performance status criteria

  • Two Suitable Umbilical Cord Blood Units: a cryopreserved dose of at least 1.5 x 107 TNC/kg. If the unit contains red cells at time of cryopreservation, the cryopreserved dose must be at least 2.0 x 107 TNC/kg. Each unit must be at least 4/6 HLA-A and B antigen, and DRB1 allele matched with the recipient. Each unit must be at least 3/6 HLA-A, B DRB1 antigen matched to each other.

Exclusion criteria

  • Patient with suitable related donor

  • AML, ALL, AUL, biphenotypic leukemia beyond CR2

  • AML evolved from myelofibrosis

  • Any acute leukemia with:

    • Morphologic relapse or persistent disease in the BM
    • Active extra-medullary leukemia including active CNS leukemia
    • Requiring greater than two cycles of chemotherapy to obtain present remission status
  • Bone marrow aplasia (defined as BM cellularity < 5% at transplant work-up)

  • MDS with 10% or greater bone marrow blasts at pre-transplant workup

  • Prior autologous or allogeneic HSC transplant at any time

  • Prior radiation therapy rendering patient ineligible for TBI

  • Any uncontrolled infection at time of study enrollment

  • Seropositive or NAT positive for HIV or HTLV1

  • Females who are pregnant or breast feeding

  • Patient unable to give informed consent or unable to comply with the treatment protocol including appropriate supportive care, follow-up, and research tests
