RATIONALE: Giving chemotherapy before a donor bone marrow transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclophosphamide, mycophenolate mofetil, or tacrolimus after transplant may stop this from happening. PURPOSE: This clinical trial is studying how well giving combination chemotherapy together with tacrolimus and mycophenolate mofetil works in treating patients who are undergoing a donor bone marrow transplant for hematologic cancer.

Study summary:

OBJECTIVES: Primary - Determine the optimal dose of post-transplant immunosuppression comprising high-dose cyclophosphamide, tacrolimus, and mycophenolate mofetil administered after myeloablative conditioning chemotherapy comprising busulfan and cyclophosphamide followed by allogeneic bone marrow transplantation in patients with high-risk hematologic malignancies. - Determine the incidence and severity of acute graft-versus-host disease in patients treated with this regimen. - Determine other toxic effects of this regimen in these patients. Secondary - Determine immune reconstitution in patients treated with this regimen. - Determine disease control in patients treated with this regimen. OUTLINE: This is a pilot study. Patients are stratified according to age (≤ 19 years old vs > 19 years old). - Myeloablative conditioning chemotherapy: Patients receive busulfan IV or orally 4 times daily on days -7 to -4 OR days -6 to -3 and cyclophosphamide IV over 1 hour once daily on days -3 to -1 OR days -2 and -1. - Allogeneic bone marrow transplantation: Patients undergo allogeneic bone marrow transplantation on day 0. - Immunosuppression therapy: Patients receive high-dose cyclophosphamide IV over 1 hour on days 3 and 4. After completion of study transplantation, patients are followed at 30 and 60 days, 6 months, 1 year, and then annually thereafter.
