Key clinical point: Tyrosine kinase inhibitor (TKI) discontinuation in patients with chronic-phase chronic myeloid leukemia (CML-CP) is common in routine clinical practice and is as successful as when performed within a clinical trial.

Major finding: TKI discontinuation of longer than 1 month was reported in 235 patients. Overall, 128 patients discontinued as they achieved a deep molecular response, of which 70.3% discontinued outside a clinical trial. Among patients discontinuing TKI outside a clinical trial, 62.2% remained treatment free after a median follow-up of 1.6 years, which compares favorably to that observed in clinical trials.

Study details: This was a retrospective, population-based study of 584 patients diagnosed with CML-CP between 2007 and 2012 from the Swedish CML registry.

Disclosures: No funding source was identified. U Olsson-Stromberg reported honoraria from Ariad. The other authors had no disclosures.
