RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining bone marrow or peripheral stem cell transplantation with chemotherapy may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus either bone marrow or peripheral stem cell transplantation in treating patients with myeloproliferative disorders.

Study summary:

OBJECTIVES: - Assess disease free survival in patients with idiopathic myelofibrosis treated with a preparative busulfan/cyclophosphamide regimen followed by allogeneic bone marrow or peripheral blood stem cell transplantation. - Determine the risk of primary graft failure in these patients. OUTLINE: Patients receive a preparative regimen consisting of oral busulfan every 6 hours on days -7 through -4 and cyclophosphamide on days -3 and -2. Patients then receive allogeneic bone marrow or peripheral blood stem cells on day 0. Patients registered on protocol FHCRC-1106.00 randomized to stem cell transplant receive unmodified G-CSF-mobilized stem cells from an HLA-identical donor. Patients receive cyclosporine/methotrexate or tacrolimus/methotrexate as prophylaxis for graft-versus-host disease (GVHD). Patients receiving marrow from unrelated donors are eligible for appropriate GVHD prophylaxis studies. Patients are followed at 6 and 12 months after transplant. PROJECTED ACCRUAL: A maximum of 20 patients will be accrued for this study over approximately 3.5 years.
