| Examine whether the implementation of a pediatric protocol under a prospective registry can increase 3-year event-free survival in this population from 45% to 60%. | — |
Secondary
| Measure | Time frame |
|---|---|
| To compare OS and EFS of this cohort with other publications from developed countries and with our historical cohort before this study. ;To develop a cooperative network for ALL treatment, aiming to Exchange experiences and ranking of priorities regarding this disease in our country. ;Provision of molecular and cytogenetic complementation for all included patients, allowing an increased classification of newly diagnosed cases. ;To address the prognostic impact of MRD on EFS and OS when measured in two timepoints throughout the treatment. ;To evaluate the cumulative incidence of allogeneic hematopoietic stem-cell transplantation (HSCT) over the treatment for all eligible patients. ;To determine prognostic factors for EFS, OS and relapse in adult ALL. To describe main death causes and predictors of non-relapse mortality. ;To build a biorepository of leukemia samples at the diagnosis, aiming to develop further translational studies on this population. | — |
