Chemotherapy and Total-Body Irradiation Followed by Donor Umbilical Cord Blood Transplant, Cyclosporine, and Mycophenolate Mofetil in Treating Patients With Hematologic Cancer

• Status: Completed
• Trial end date: 2006-01-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Giving low doses of chemotherapy, such as cyclophosphamide and fludarabine, 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. 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 cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

PURPOSE: This clinical trial is studying how well giving chemotherapy together with total-body irradiation followed by donor umbilical cord blood transplant, cyclosporine, and mycophenolate mofetil works in treating patients with hematologic cancer.

Criteria

DISEASE CHARACTERISTICS:

• Diagnosis of a hematologic malignancy of 1 of the following types:

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

• In complete remission (CR) by morphology (< 5% blasts in the bone marrow), as defined by 1 of the following:

• In first CR (CR1) and meets ≥ 1 of the following high-risk criteria:

• High-risk cytogenetics (e.g., those associated with myelodysplastic syndromes [MDS] or complex karotype)

• Preceding MDS

• More than 2 courses of therapy was required to obtain CR

• In second or greater CR

• No morphologic relapse

• Cytogenetic relapse or persistent disease allowed

• Acute lymphocytic leukemia (ALL), meeting the following criteria:

• In CR, as defined by 1 of the following:

• In CR1 and meets ≥ 1 of the following high-risk criteria:

• Unfavorable high-risk cytogenetics [t(9;22), t(1;19), t(4;11) or other MLL rearrangements]

• More than 1 course of therapy was required to obtain CR

• In second or greater CR

• No morphologic relapse or persistent disease

• Chronic myelogenous leukemia (CML), excluding refractory blast crisis

• Advanced myelofibrosis

• Advanced myelodysplasia (blasts < 10% [otherwise need AML induction pre-transplant]), meeting ≥ 1 of the following criteria:

• Refractory anemia with excess blasts (RAEB)

• RAEB in transformation

• Refractory anemia with severe pancytopenia

• High-risk cytogenetics

• Non-Hodgkin's lymphoma (NHL), meeting the following criteria:

• One of the following histologic subtypes:

• Mantle cell NHL

• Disease progression after initial therapy (e.g., CHOP)

• Beyond CR1 or beyond first partial remission (PR)

• Intermediate-grade NHL in second or greater CR or PR

• High-grade NHL

• Stage III or IV disease AND received initial therapy

• Stage I or II disease at diagnosis that subsequently progressed after a prior response duration of < 1 year

• No chemotherapy-refractory NHL (i.e., < progressive disease after > 2 salvage regimens)

• Donor available, meeting the following criteria:

• No other existing HLA-identical related donor available

• 4-6/6 HLA-A, -B, and -DRB1, matched unrelated donor by molecular techniques

• A and B to antigen level resolution

• DR to allele resolution

• Umbilical cord blood (UCB) graft may consist of one or two UCB units NOTE: A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. 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.
