Treatment of Newly Diagnosed Patients With Acute Promyelocytic Leukemia (PETHEMA LPA 2005): Remission Induction With ATRA + Idarubicin. Risk-adapted Consolidation With ATRA and Anthracycline-based Chemotherapy (Idarubicin/Mitoxantrone) With Addition of Ara-C for High-risk Patients. Maintenance Therapy With ATRA + Low Dose Chemotherapy (Methotrexate + Mercaptopurine).

Overview
Brief Summary
Primary objectives
- To evaluate the efficacy and toxicity of a risk-adapted protocol that use idarubicin for induction and consolidation therapy in patients with APL.
- To evaluate the impact of mitoxantrone reduction on the event-free, disease-free, and overall survival, as well as on the duration of remission and cumulative incidence of relapse in low- and intermediate-risk patients with APL.
- To evaluate the impact of the addition of ara-C to idarubicin courses of consolidation for high-risk patients (administered as in the original GIMEMA protocols) on the event-free, disease-free, and overall survival, as well as on the duration of remission and cumulative incidence of relapse.
- To evaluate the toxicity of the induction, consolidation, and maintenance chemotherapy in the whole series and in each treatment group in patients with APL.
Secondary objectives
• To compare all outcomes with those achieved with the PETHEMA LPA99 protocol.
Detailed Description
Treatment of induction with the simultaneous administration of ATRA (45 mg/m2 day until the RC) and idarubicine (12 mg/m2 days 2, 4, 6 and 8), 3 monthly cycles of consolidation with ATRA (45 mg/m2 days 1-15) and idarubicine (5 mg/m2 days 1-4) in the cycle #1, mitoxantrone (10 mg/m2 days 1-3) in the cycle #2 and idarubicine (12 mg/m2 day 1) in the cycle #3. The consolidation was reinforced for the group of patients with intermediate risk by means of an increase of the idarubicine to 7 mg in the cycle #1 and to 2 days in the cycle #3. In the patients of high risk, the consolidation was reinforced with the addition of altar-c in the cycles #1 and #3. For the maintenance treatment, one will administer to intermittent ATRA (15 days every 3 months) and chemotherapy low doses with methotrexate and 6-mercaptopurina during two years

Eligibility Criteria
Inclusion Criteria
- •Age ≤ 75 years.
- •Morphologic Diagnosis of LPA (FAB M3 or variant M3). Those cases without typical morphology but with PML-RARα reordering also must be including.
- •Genetic Diagnosis: t (15; 17) demonstrated by cariotipo conventional, FISH, PML-RARα reordering detected by RT-PCR or a pattern microspeckled demonstrated with antibody anti-PML (positive PGM3). Obvious, it will be had the result of these tests once initiated the treatment on the basis of a suspicion diagnoses morphologic
Exclusion Criteria
- •Age \>75 years (the treatment with this protocol can be considered individually)
- •Absence of PML-Rare reordering.
- •To have received previously some type of treatment for LPA, including chemotherapy or retinoides. The previous treatment with corticoids, hidroxiurea or leucoaféresis is not reason for exclusion.
- •To have received chemotherapy or x-ray for the treatment of a disease vitiates previous.
- •Associate Neoplasia.
- •Serious psychiatric Disease.
- •Seropositividad for VIH.
- •Contraindication to receive intensive chemotherapy, specially antraciclinas.
- •Sérica Creatinina ≥ 2,5 mg/dL (≥ 250 μmol/l).
- •Bilirrubina, fosfatasa alkaline, or GOT \> 3 times the normal limit
