简要总结
This randomized phase III trial is studying tretinoin and combination chemotherapy to see how well they work compared to tretinoin, combination chemotherapy, and arsenic trioxide in treating patients with acute promyelocytic leukemia that has not been treated previously. Drugs used in chemotherapy, such as daunorubicin, cytarabine, mercaptopurine, methotrexate, and arsenic trioxide, work in different ways to stop cancer cells from dividing so they stop growing or die. Tretinoin may help leukemia cells develop into normal white blood cells. It is not yet known which regimen is more effective for acute promyelocytic leukemia.
详细描述
PRIMARY OBJECTIVES:
i. To compare the efficacy (event-free survival) and toxicities of two induction/consolidation therapies for patients with untreated APL: ATRA/ara-C/daunorubicin with or without arsenic trioxide (As2O3).
II. To evaluate the efficacy (disease-free survival) and toxicities of maintenance therapy with intermittent ATRA vs intermittent ATRA plus 6-MP/MTX for patients with APL who achieve a complete response.
III. To explore the relationship between CD56 expression at diagnosis and clinical outcomes.
IV. To evaluate the cardiac toxicity of intensive daunorubicin therapy, as given in this study, to pediatric patients.

入选标准
- •Patients must have a clinical diagnosis of acute promyelocytic leukemia (APL) with proof of APL morphology (FAB-M3) confirmed by RT-PCR assay; a patient may be entered prior to completion of RT-PCR studies, but a patient who is subsequently found to be PML-RARα negative and RARα-PML negative will be removed from protocol treatment
- •FAB clasification: the aspirate smear must show M3 characteristics and at least 30% of cells must be abnormal promyelocytes with heavy granulation; the overall marrow cellularity must be normocellular or hypercellular; patients with the microgranular variant (M3V) are eligible, and the diagnosis will be based on characteristic morphologic findings (e.g., reniform or bilobed nuclei)
- •RT-PCR assay: submission of samples for RT-PCR assays for PML-RARα/RARα-PML transcripts is mandatory; the results do not have to be known prior to initiation of therapy; if the assay is subsequently found to be negative, the patient will be removed from protocol treatment and treated at the discretion of the responsible physician
- •Prior treatment: the patient must not have received any systemic definitive treatment for APL, including cytotoxic chemotherapy or retinoids; prior therapy with corticosteroids, hydroxyurea or leukapheresis will not exclude the patient
- •Non-pregnant, non-nursing: treatment under this protocol would expose an unborn child to significant risks; patients should not be pregnant or plan to become pregnant while on treatment; women and men of reproductive potential should agree to use an effective means of birth control; there is an extremely high risk of fetal malformation if pregnancy occurs while on ATRA in any amount even for short periods

研究组 & 干预措施
Arm I
Induction: All patients receive oral tretinoin every 12 hours beginning on day 1 until complete response or for a maximum of 90 days. Patients also receive daunorubicin IV on days 3-6 and cytarabine IV continuously on days 3-9.
Consolidation: All patients achieving CR or PR after completion of tretinoin, proceed to consolidation within 2 weeks of achieving CR or PR, but not prior to 30 days from the start of induction. Patients are randomized to 1 of 2 treatment arms.
Patients receive oral tretinoin every 12 hours on days 1-7 and daunorubicin IV on days 1-2 or days 1-3, depending on age. Patients may receive an additional course. Treatment begins no earlier than 2 weeks and no later than 4 weeks after hematopoietic recovery.
