简要总结
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.
PURPOSE: Phase II trial to study the effectiveness of arsenic trioxide in treating patients who have relapsed or refractory chronic myelogenous leukemia.
详细描述
OBJECTIVES: I. Determine the antileukemic efficacy of arsenic trioxide in patients with relapsed and/or refractory, chronic, accelerated, or blastic phase chronic myelogenous leukemia. II. Determine the pattern of clinical adverse experience in this patient population administered this drug.
OUTLINE: Patients are stratified according to disease stage (chronic phase vs accelerated phase or blastic phase). Patients receive arsenic trioxide IV over 1 hour on consecutive days or weekdays only for a total of 25 days followed by 3-5 weeks of rest. Treatment continues for a maximum of 6 courses in the absence of unacceptable toxicity or disease progression. Patients with responding disease are followed at least monthly.
PROJECTED ACCRUAL: A total of 10-27 patients will be accrued for the chronic phase stratum of this study within 2 years. A total of 17-37 patients will be accrued for the accelerated and blastic phases stratum of this study within 2 years.
