Advancing chronic myeloid leukemia research with next-generation sequencing: potential benefits, limitations, and...

Next-generation sequencing (NGS) has emerged as a powerful tool for advancing research in chronic myeloid leukemia (CML) by providing a deeper understanding of its genetic complexity. Beyond detecting the hallmark BCR::ABL1 fusion gene, NGS has enabled the identification of additional mutations associated with disease progression, therapy resistance, and clonal evolution. NGS also facilitates the detection of rare BCR::ABL1 fusion variants and cryptic rearrangements, offering a more refined genetic characterization of the disease. Additionally, it enhances the study of minimal residual disease (MRD) and evolving resistance patterns, which are crucial for developing targeted therapeutic strategies. However, challenges such as data interpretation, standardization, and cost constraints continue to limit the widespread application of NGS in routine research and clinical settings. This review explores the contributions of NGS to CML research, highlighting its role in uncovering novel genetic alterations, tracking clonal evolution, and identifying potential therapeutic targets. As sequencing technologies evolve, NGS is expected to further shape the future of CML research, providing critical insights that may ultimately refine disease management strategies.
