N2 - Imatinib (IM) dramatically improved the prognosis of chronic myeloid leukemia (CML), particularly with newly diagnosed patients in a chronic phase (CP) [1]. The most robust source of data about IM efficacy in this setting is the IRIS trial. However, every day clinical practice data are still scarce. We analyzed IM efficacy and safety in the first-line therapy of 152 consecutive adult CP-CML patients from a defined region. The estimated 4-year cumulative incidences of complete hematologic, complete cytogenetic, major, and complete molecular responses were 95.3%, 80.6%, 65.4%, and 39.2%, respectively. The 4-year probability of overall and progression-free survival (PFS) defined as with the IRIS [2] was 91.5% and 78.1%, respectively. We thus confirmed very good IM efficacy also in patients not participating in clinical trials. However, the estimated 4-year event-free survival (EFS), which also counted failure events according to valid recommendations [3] or IM discontinuation due to intolerance, was only 60.7%. The 4-year probability of an alternative treatment-free survival, our newly defined parameter, which better reflects the proportion of patients remaining on IM despite an event, was 67.6%. Therefore, more appropriate selection and unification of survival analyses end-points is desirable to describe and compare IM real efficacy.
