Chronic myeloid leukemia (CML) is driven by the BCR::ABL1 fusion gene, and the introduction of tyrosine kinase inhibitors (TKIs) has dramatically improved long-term survival. In Japan, five agents—imatinib (Glivec®), dasatinib (Sprycel®), nilotinib (Tasigna®), bosutinib (Bosulif®), and STAMP inhibitor asciminib (Scemblix®)—are currently approved for first-line therapy. Each has distinct efficacy and toxicity profiles, requiring individualized treatment decisions based on age, comorbidities, cardiovascular risk, fertility, adherence, and financial factors. Recent advances have shifted treatment goals from disease control to treatment-free remission (TFR), with imatinib, dasatinib, and nilotinib supported by robust clinical trial data. Emerging strategies, such as low-dose regimens and step-up dosing of TKI, highlight the importance of balancing efficacy with tolerability and quality of life. Looking forward, immunologic determinants of TFR and novel therapeutic approaches, including targeting CML stem cells with agents such as asciminib or demethylating drugs, may offer prospects for cure. This review summarizes the current evidence and practical considerations in selecting first-line therapy for chronic-phase CML, with a focus on optimizing long-term outcomes and advancing toward individualized and potentially curative strategies.
