Brief summary: RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with autologous bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells.

PURPOSE: Phase II trial to study the effectiveness of chemotherapy followed by autologous bone marrow transplantation in treating patients with chronic myelogenous leukemia.

Detailed description: OBJECTIVES: I. Evaluate the ability of c-myb antisense oligodeoxynucleotide to purge bone marrow cells of clonogenic chronic myelogenous leukemia tumor cells and repopulate the bone marrow with normal stem cells in patients treated with high-dose busulfan and cyclophosphamide followed by autologous bone marrow transplantation using marrow treated with c-myb antisense oligodeoxynucleotide. II. Determine the response rate, degree of hematopoietic reconstitution, overall survival, and relapse-free survival of patients treated with this regimen. III. Determine the toxicity of this regimen in these patients.

OUTLINE: Patients undergo bone marrow harvest. The bone marrow is treated with c-myb antisense oligodeoxynucleotide and cryopreserved. A portion of the marrow is cryopreserved untreated in case of engraftment failure. Patients receive oral busulfan every 6 hours on days -7 to -4 for a total of 16 doses. Patients receive cyclophosphamide IV over 1 hour on days -3 and -2. Bone marrow is reinfused on day 0. Patients receive filgrastim (G-CSF) subcutaneously daily beginning on day 0 and continuing until blood counts recover. Patients are followed every 2-3 months for 2 years.

PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study within 18-24 months.
