简要总结
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. It is not yet known which combination chemotherapy regimen is more effective in treating young patients with acute lymphoblastic leukemia.
PURPOSE: This partially randomized phase III trial is studying how well combination chemotherapy works in treating young patients with relapsed or refractory acute lymphoblastic leukemia.
详细描述
OBJECTIVES:
Primary
- Evaluate the progression-free survival (defined as the time from study entry to the first occurrence of progression, relapse, death while in complete clinical remission, or second malignancy) of United Kingdom patients with relapsed or refractory acute lymphoblastic leukemia stratified by risk group.
- Evaluate whether a minimal residual disease (MRD) level of 10^-4 is a suitable criterion at the end of induction therapy on which to decide whether chemotherapy or stem cell transplantation will be most beneficial to patients with intermediate-risk disease.
Secondary
- Use MRD as a surrogate marker for response to therapy.
