简要总结
RATIONALE: Drugs used in chemotherapy, such as clofarabine and daunorubicin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving clofarabine together with daunorubicin may kill more cancer cells.
PURPOSE: This phase II trial is studying how well giving clofarabine together with daunorubicin works in treating older patients with newly diagnosed acute myeloid leukemia.
详细描述
OBJECTIVES:
Primary
- Study complete response (CR) and CR without platelet recovery (CRp) following treatment with clofarabine and daunorubicin hydrochloride in older patients with newly diagnosed acute myeloid leukemia.
Secondary
- Study disease-free and overall survival of these patients following treatment with this regimen.
- Compare disease-free and overall survival of patients whose cells do or do not demonstrate apoptosis following treatment with this regimen.

结局指标
主要结局
Complete Remission (CR)
时间窗: 2 years
Complete Response/Remission (CR) was defined on morphologic criteria at a single response assessment as follows: A bone marrow aspirate or biopsy of \< 5% blasts, with evidence of normal hematopoiesis; Absence of Auer rods in the blast that are present; Absence of extramedullary disease \[imaging required only if obtained pretreatment for known site(s) of disease\]; If applicable and available, absence of a unique phenotype determined at the pretreatment specimen, as assessed by immunophenotyping; Recovery of peripheral counts (platelets ≥100x109/L, and ANC ≥1.0x109/L). Peripheral count recovery must be documented no earlier than 7 days prior to, and no later than 14 days following, the bone marrow assessment that provides evidence of the CR. Complete Response/Remission without platelet recovery (CRp) was defined as all criteria for CR except for thrombocytopenia (platelet count ≥75x109/L).
