Endpoint primari e secondari
Main Objective: ?Achieving an EFS, which is not inferior to the ML-DS 2006 trial: 5yr-EFS; 87?3%;Secondary Objective: ?Reduction of toxicity: severe adverse events (CTCAE v4.0 grade III or higher)
?Identification of prognostic factors concerning the risk of relapse, toxicity and poor outcome
?Evaluate the role of different methods in the determination of minimal residual disease measurement
?Evaluation of somatic SNVs as a predictive biomarker: relation of patients? outcome to the specific somatic SNVs
?Exploration of the role of trisomy 8 as a predictive biomarker
?Exploration of molecular resistance/relapse mechanisms
;Primary end point(s): Event-free survival (EFS), defined as time from diagnosis to the first event or last follow-up. Events are death from any cause, failure to achieve remission, relapse, and secondary malignancy. Failure to achieve remission is considered as an event on day 0.
;Timepoint(s) of evaluation of this end point: After 150 are included and the 5-yrs-follow up is over. (ICTRP)

Secondary end point(s): ?Overall survival (OS), as defined as the time of diagnosis to death from any cause or last follow-up.
?Disease-free survival (DFS)
?Early Response Rate (CR, CRp, CRi)) after induction
?Treatment-related mortality (TRM)
?Minimal residual disease (FACS and NGS)
?Adverse events (according to NCI CTCAE v4.0)
?Duration of myelosuppression
;Timepoint(s) of evaluation of this end point: After 150 are included and the 5-yrs-follow up is over. (ICTRP)
