Protocol For the Treatment Acute Lymphoblastic Leukemia With Ph 'Negative in Elderly Patients (> 55 Years)

Brief description of study

The protocol objective is providing adequate treatment and based on broad consensus in elderly patients with Acute Lymphoblastic Leukemia (ALL). Apply uniform treatment that enables a joint analysis of results strong enough to make conclusions on specific subgroups of patients (genotypic subtypes, particularly LAL Bcr/abl positive, phenotype, or strata of age or associated diseases). Provide results of a treatment to consider standard against which to compare the results of phase II trials of experimental drugs that undoubtedly will be activated in the coming years

Detailed Study Description

Prephase (days -5 to -1) Dexamethasone 10 mg/m2 bolus day IV for 5 days (-5 to -1). Supplementary treatment: hydration minimum 2000 ml/day, allopurinol 300 mg / day, gastric protection (as center), daily monitoring of blood glucose, daily monitoring of renal function. Intrathecal treatment (diagnosis and prophylactic) day -5: 12 mg were administered intrathecal methotrexate. The morphological study of the CSF will be defining initial CNS involvement by LAL. Although it is recommended immunophenotypic study of CSF, the definition of CNS involvement by LAL (and its therapeutic consequences) based on morphological observation of blasts in CSF cytocentrifuge.

Remission induction:

Tolerance prephase period can be used to establish the final indication of treatment (standard protocol or frail patients). Day 0 is free of treatment and is considered as +1 the first day of induction. The total duration of the induction is 30 days, consists of two phases (Phase I, days +1 to +14 and phase II, days +15 to +30). Mandatory testing is considered counting the percentage of blasts in peripheral blood +8 day of induction, a myelogram to day +14 to assess early response and a day +35 to assess the complete remission
