Since the treatment after dasatinib and blinatumomab is not uniform and highly dependent on medical decisions, the primary aim of this ancillary trial is to evaluate the long-term follow-up of patients enrolled in the GIMEMA 2116, in terms of overall survival (OS). Furthermore, the secondary objectives are the collection of data and survival outcomes relative to the therapeutic choices carried out after dasatinib and blinatumomab (i.e. allo-SCT, autologous transplant, TKI maintenance, etc), duration of CMR, DFS, long-term safety profile. A correlation of survival outcomes (OS, DFS, etc) with the clinical and biological findings will be carried out with data collected at diagnosis and during the follow-up within the LAL2116 trial.
