Dose optimization of tyrosine kinase inhibitor therapy in chronic myeloid leukemia.

The therapeutic outcomes of chronic myeloid leukemia (CML) have improved dramatically since tyrosine kinase inhibitors (TKIs) became available in clinical practice. Life expectancy of patients with CML is now close to that of the general population. Patients with CML who achieve sustained deep molecular response may discontinue TKI therapy. However, most patients still require TKI therapy for long periods without sustained deep molecular response. Given the awareness of increased incidence of arterial occlusive events in patients on TKI therapy, the optimal TKI selection should be based on age, comorbidities, risk classification, and goals of treatment. Dose optimization of TKI therapy reduces the incidence of adverse events while maintaining efficacy in CML.
