Résumé
Date de début de l'étude : 1 février 1998
Date à laquelle le premier participant a commencé l'étude.OBJECTIVES: I. Determine the safety of topotecan in combination with fludarabine, cytarabine, and filgrastim (FLAG) in patients with poor prognosis acute myeloid leukemia, myelodysplastic syndrome, or recurrent or refractory acute lymphocytic leukemia. II. Determine the maximum tolerated dose of topotecan in the FLAG regimen in these patients. III. Assess the complete remission rates in patients treated with this regimen. OUTLINE: Patients with complete response proceed to further therapy according to age. 65 and under: Patients receive etoposide by IV continuously for 5 days, cytarabine IV over 2 hours every 12 hours for 4 days, and filgrastim (G-CSF) subcutaneously. Peripheral blood stem cells (PBSC) are then harvested. Patients then receive oral busulfan every 6 hours on days -7 to -4 and etoposide IV over 10 hours on day -3. PBSC are reinfused on day 0. Over 65: Patients receive oral isotretinoin and vitamin E daily. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients are followed every month for 1 year and then every 3 months thereafter. PROJECTED ACCRUAL: A total of 15 patients will be accrued for this study within 3-4 years.
