With the availability of TKI and proper management, the expected survival of patients with chronic phase CML (CML-CP) is approaching that of the general population.Any of the four TKIs approved for frontline therapy of CML-CP may be selected. These include imatinib, dasatinib, nilotinib, and bosutinib. Second-generation TKIs are superior to imatinib in achieving faster and deeper responses compared with imatinib, but survival is similar because of the availability of effective TKI salvage therapies.Factors considered in choosing TKI therapy in the frontline setting include patient age, comorbidities, adverse events profile, and disease risk score, as well as the TKI-associated schedule of administration and cost. Kinase domain mutation profile plays no role in selecting an initial TKI but becomes relevant in relapse.Most TKIs are reasonably well tolerated with close observation and supportive care. However, each TKI therapy has a distinct toxicity profile that should be considered when deciding on therapy.Second- and third-generation TKIs have not been compared head to head. Mutational analysis is required after failure of imatinib or second-generation TKIs, or after progression to accelerated phase CML (CML-AP) or blastic phase (CML-BP). Baseline mutational analysis are not recommended in newly diagnosed CML-CP because it does not help predict treatment outcome.Allogeneic stem cell transplant should be considered in patients who progress from CML-CP to CML-AP/CML-BP after TKI therapy failure and who fail second- or third-generation TKI while still in CML-CP.
