Combination Chemotherapy Followed by Peripheral Stem Cell Transplantation in Treating Patients With Chronic Myelogenous Leukemia

Fred Hutchinson Cancer Center30 enrolled

Overview

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by G-CSF and peripheral stem cell transplantation in treating patients with chronic myelogenous leukemia.

OBJECTIVES: I. Evaluate the efficacy of MCE (mitoxantrone/cytarabine/etoposide) followed by granulocyte colony-stimulating factor to mobilize peripheral blood stem cells (PBSC) in patients with chronic myeloid leukemia (CML). II. Evaluate the toxicity of this regimen. III. Evaluate the cytoreductive effects of this regimen in CML as determined by the ability to mobilize Philadelphia chromosome-negative PBSC. IV. Assess the time of peak CD34+ and CD34+/CD38- cell concentrations in the peripheral blood of patients treated with this regimen. OUTLINE: The following acronyms are used: ARA-C Cytarabine, NSC-63878 DHAD Mitoxantrone, NSC-301739 G-CSF Granulocyte Colony-Stimulating Factor (source not specified) HU Hydroxyurea, NSC-32065 MCE DHAD/ARA-C/VP-16 VP-16 Etoposide, NSC-141540 Single-Agent Cytoreduction followed by 3-Drug Combination Chemotherapy/Stem Cell Mobilization. HU; followed by MCE; G-CSF. PROJECTED ACCRUAL: 30 patients will be entered over 3 years.
