  • Acute myeloid leukemia (AML) meeting any of the following criteria:

    • First complete remission with high-risk karyotype

      • Translocations t(15;17) allowed only if failed first-line induction therapy OR molecular evidence of persistent disease exists
      • Translocations t(8;21) and inv(16) allowed only if failed first-line induction therapy

  • Acute lymphoblastic leukemia meeting any of the following criteria:

    • Failed induction therapy and has minimal residual disease* by salvage therapy
    • First complete remission with high-risk karyotype (e.g., t[4;11] or t[9;22])
    • Relapsed disease allowed provided a second or subsequent complete remission or minimal residual disease* is achieved

  • Chronic myelogenous leukemia meeting any of the following criteria:

    • Persistent or relapsed disease after 1 year of imatinib mesylate therapy

    • Accelerated phase or blast crisis

      • Blast crisis allowed after reinduction chemotherapy places disease in chronic phase

  • Myelodysplastic syndromes meeting any of the following criteria:

    • Refractory to medical management
    • Cytogenetic abnormalities predictive of transformation into acute leukemia, including 5q-, 7q-, monosomy 7 and trisomy 8, or evidence of evolution to AML (e.g., refractory anemia with excess blasts (RAEB) or RAEB in transformation)

  • Non-Hodgkin's lymphoma or Hodgkin's lymphoma meeting any of the following criteria:

    • Beyond first complete remission or failed primary induction therapy and demonstrated sensitivity to therapy during the 6 months before transplantation

    • Recurrent disease after autologous stem cell transplantation

      • Must be at least 3 months posttransplantation
    • Cyclin D1+ mantle cell lymphoma allowed after induction therapy and in first remission

  • Multiple myeloma meeting either of the following criteria:

    • Refractory or relapsed disease
    • Residual disease after autologous transplantation

  • Chronic lymphocytic leukemia (CLL) meeting all of the following criteria:

    • Peripheral blood absolute lymphocyte count greater than 5,000/mm^3
    • Small to moderate size lymphocytes and less than 55% pro-lymphocytes, atypical lymphocytes, or lymphoblasts morphologically
    • B-cell or T-cell

    • Philadelphia negative
• Availability of a HLA-A, B, and DR identical family donor OR HLA-A, B, and DR genetically matched unrelated donor

• Must meet 1 of the following criteria:

  • At least 55 years of age at time of transplantation
  • Received extensive prior therapy (i.e., more than 1 year of alkylator therapy or more than 2 different prior salvage regimens) or stem cell transplantation with myeloablative conditioning (either autologous or allogeneic)
  • Presenting with comorbid condition (e.g., abnormal cardiac, pulmonary, or renal function and/or prior life-threatening infection) that precludes eligibility for enrollment in allogeneic transplantation protocols with full ablation conditioning
• No active CNS disease NOTE: *Defined as having no circulating blasts, absolute neutrophil count greater than 1,000/mm3 and less than 10% blasts in bone marrow at least 3 weeks after last systemic chemotherapy
