About

RATIONALE: Giving low doses of chemotherapy and radiation therapy before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells when they do not exactly match the patient's blood. The donated stem cells may replace the patient's immune system and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving antithymocyte globulin before transplant and cyclosporine and mycophenolate mofetil after transplant may stop this from happening.

PURPOSE: This phase I/II trial is studying the side effects of giving combination chemotherapy together with total-body irradiation before donor umbilical cord blood transplant and to see how well they work in treating patients with advanced hematologic cancer, metastatic breast cancer, or kidney cancer.

Full description

OBJECTIVES:

Primary

• Determine the safety of nonmyeloablative preparative regimen comprising cyclophosphamide, fludarabine, and total-body irradiation with or without anti-thymocyte globulin, in terms of non-relapse mortality at day 100 post-transplantation, in patients with advanced hematologic malignancies, metastatic breast cancer, or renal cell cancer who are undergoing umbilical cord blood transplantation from an unrelated donor.

Secondary

• Determine the hematopoietic recovery and degree of chimerism on days 21, 60, 100, 180, and 360 post-transplantation.
• Determine the incidence of grade II-IV and III-IV acute graft-versus-host disease (GVHD) by day 100 post-transplantation and chronic GVHD at 1 year post-transplantation.
• Evaluate the risk of relapse at 1 year post-transplantation.
• Determine overall survival at 1 year post-transplantation.

OUTLINE:

• Nonmyeloablative preparative regimen: Patients receive cyclophosphamide IV over 2 hours on day -6 and fludarabine IV over 1 hour on days -6 to -2. Patients also undergo total-body irradiation on day -1. Some patients* may also receive anti-thymocyte globulin (ATG) IV twice daily on days -6 to -4.

NOTE: *Patients who have not had prior combination chemotherapy within the past 3 months OR who only received 1 prior induction course for the treatment of acute lymphoblastic leukemia, acute myeloid leukemia, myelodysplastic syndromes, or chronic myelogenous leukemia in blast crisis receive ATG during the preparative regimen.

• Umbilical cord blood transplantation (UCBT): Patients undergo UCBT from an unrelated donor on day 0.
• Graft-versus-host disease prophylaxis: Patients receive cyclosporine IV over 2 hours or orally 2-3 times daily beginning on day -3 and continuing until day 100 followed by a taper until day 180. Patients also receive mycophenolate mofetil IV or orally twice daily beginning on day -3 and continuing until day 30 or until 7 days after engraftment.

After transplantation, patients are followed periodically for 2 years.

PROJECTED ACCRUAL: A total of 120 patients will be accrued for this study.

Enrollment: 148 patients

Inclusion and exclusion criteria

DISEASE CHARACTERISTICS:

• Diagnosis of 1 of the following:

  • Acute myeloid leukemia (AML), meeting 1 of the following criteria:

    • In first complete remission (CR1) by morphology AND at high risk, as evidenced by 1 of the following:

      • AML secondary to myelodysplastic syndromes (MDS)
      • High-risk cytogenetics, such as those associated with MDS or complex karyotype
      • More than 2 courses of therap were required to obtain a CR

    • In second or greater CR by morphology

    • In morphologic relapse or persistent disease, defined as > 5% blasts in normocellular bone marrow OR any percentage of blasts if blasts have unique morphologic markers (e.g., auer rods)

    • In cytogenetic relapse (without morphologic relapse)

  • Acute lymphoblastic leukemia (ALL), meeting 1 of the following criteria:

    • In CR1 by morphology AND at high risk, as evidenced by 1 of the following:

      • High-risk cytogenetics, such as t(9;22), t(1;19), t(4;11), or other MLL rearrangements
      • More than 1 course of therapy was required to obtain a CR

    • In second or greater CR by morphology

    • In morphologic relapse or persistent disease as defined for AML

    • In cytogenetic relapse (without morphologic relapse)

  • Chronic myelogenous leukemia

    • All types allowed except refractory blast crisis

  • Non-Hodgkin's lymphoma (NHL)

    • No intermediate- or high-grade NHL or mantle cell NHL that is progressive on salvage therapy
    • Stable disease allowed provided it is non-bulky

  • Hodgkin's lymphoma

    • No progressive disease on salvage therapy
    • Stable disease allowed provided it is non-bulky

  • Chronic lymphocytic leukemia

  • Multiple myeloma

  • MDS

    • Any subtype allowed, including refractory anemia if there is severe pancytopenia or complex cytogenetics

    • Less than 5% blasts

      • If patient has blasts ≥ 5% then they must undergo induction therapy before transplantation

  • Metastatic breast cancer

    • Disease must have responded to recent chemotherapy OR in plateau after response to chemotherapy

  • Renal cell cancer

  • Acquired bone marrow failure syndromes

• Small percentage of blasts that is equivocal between marrow regeneration vs early relapse allowed provided there are no associated cytogenetic markers consistent with relapse (for patients with AML or ALL)

The terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. However, this protocol uses the former terminology.
