Key clinical point: Creatine kinase (CK) elevation was associated with superior survival in patients with newly diagnosed chronic-phase chronic myeloid leukemia (CML-CP) receiving first-line tyrosine kinase inhibitor (TKI) therapies.
Major finding: Overall, 71.7% patients had CK elevation after TKI initiation. Patients with vs. without elevated CK levels had improved overall survival (adjusted hazard ratio [aHR] 0.31; P < .001) and event-free survival (aHR 0.51; P = .003).
Study details : This retrospective study included 283 patients with newly diagnosed CML-CP treated with first-line TKI therapies.
