Tyrosine kinase inhibitors (TKIs) have vastly improved long-term outcomes for patients with chronic myeloid leukemia (CML). After imatinib (a first-generation TKI), second- and third-generation TKIs were developed. With five TKIs (imatinib, dasatinib, bosutinib, nilotinib, and ponatinib) targeting BCR::ABL approved in most countries, and with the recent approval of asciminib in the USA, treatment decisions are complex and require assessment of patient-specific factors. Optimal treatment strategies for CML continue to evolve, with an increased focus on achieving deep molecular responses. Using clinically relevant case studies developed by the authors of this review, we discuss three major scenarios from the perspective of international experts. Firstly, this review explores patient-specific characteristics that affect decision-making between first- and second-generation TKIs upon initial diagnosis of CML, including patient comorbidities. Secondly, a thorough assessment of therapeutic options in the event of first-line treatment failure (as defined by National Comprehensive Cancer Network and European LeukemiaNet guidelines) is discussed along with real-world considerations for monitoring optimal responses to TKI therapy. Thirdly, this review illustrates the considerations and importance of achieving treatment-free remission as a treatment goal. Due to the timing of the writing, this review addresses global challenges commonly faced by hematologists treating patients with CML during the COVID-19 pandemic. Lastly, as new treatment approaches continue to be explored in CML, this review also discusses the advent of newer therapies such as asciminib. This article may be a useful reference for physicians treating patients with CML with second-generation TKIs and, as it is focused on the physicians' international and personal experiences, may give insight into alternative approaches not previously considered.
酪氨酸激酶抑制剂 (TKI) 极大地改善了慢性髓性白血病 (CML) 患者的长期预后。在伊马替尼(第一代 TKI)之后,开发了第二代和第三代 TKI。在大多数国家批准了五种针对 BCR::ABL 的 TKI(伊马替尼、达沙替尼、博舒替尼、尼洛替尼和泊那替尼),并且在美国最近批准了 ASCiminib,治疗决策变得复杂,需要评估患者的具体情况。CML 的最佳治疗策略不断发展,越来越注重实现深度分子反应。通过本综述作者开发的具有临床相关性的病例研究,我们从国际专家的角度讨论了三个主要情况。首先,本综述探讨了影响 CML 初始诊断时第一代和第二代 TKI 之间决策的患者特定特征,包括患者合并症。其次,深入评估了一线治疗失败(根据国家综合癌症网络和欧洲白血病网指南定义)的治疗选择,并考虑了监测 TKI 治疗最佳反应的实际考虑因素。第三,本综述说明了实现无治疗缓解作为治疗目标的考虑因素和重要性。由于写作时间的原因,本综述解决了在 COVID-19 大流行期间治疗 CML 患者的血液科医生普遍面临的全球挑战。最后,随着新的治疗方法在 CML 中不断被探索,本综述还讨论了新型疗法,如 ASCiminib 的出现。对于用第二代 TKI 治疗 CML 的医生来说,本文可能是一个有用的参考,并且由于它侧重于医生的国际和个人经验,可能会为以前未考虑过的替代方法提供见解。
