Notably, during treatment with tyrosine kinase inhibitors (TKIs), she became intolerant to first- and second-generation TKIs, including the branded and generic imatinib, nilotinib, and dasatinib, followed by progression into lymphoid blast phase. This case highlights the diagnostic challenges and therapeutic complexity of managing CML in the setting of multi-TKI intolerance. Importantly, it underscores the persistent molecular silence despite repeated RT-qPCR testing and the successful introduction of asciminib as a novel therapeutic alternative.

The introduction of imatinib in the early 2000s revolutionized CML treatment, transforming a fatal disease into a chronic condition with near-normal life expectancy for most patients...Emerging therapies such as vamotinib, KF1601, and combination regimens are being explored. Furthermore, new insights into non-kinase functions of BCR::ABL1 and the role of microRNAs in resistance open additional therapeutic avenues. This review provides a concise overview of CML from a historical and molecular perspective, highlighting diagnostic advances, evolving response criteria, and future directions in treatment.

In Japan, five agents-imatinib (Glivec®), dasatinib (Sprycel®), nilotinib (Tasigna®), bosutinib (Bosulif®), and STAMP inhibitor asciminib (Scemblix®)-are currently approved for first-line therapy. 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.

TFR patients exhibited distinct enrichment in complement and coagulation cascades (C3, C4B, F9, F11) and metabolic pathways. Plasma EV proteomes reflect CML clinical status, revealing immune and cytoskeletal alterations associated with treatment response, remission, and resistance, suggesting potential biomarkers for disease monitoring.

This case underlines the importance of considering rare but severe arterio-occlusive complications, such as retinal artery thrombosis, among the cardiovascular toxicities of nilotinib. Careful cardiovascular monitoring and early recognition of such events are crucial to optimize patient safety and treatment outcomes in CML management.

This case adds to the limited literature reporting cup-like nuclear morphology in B-ALL, which is typically associated with varied cytogenetic abnormalities, including BCR::ABL1 fusion and hyperdiploidy [3, 4]. The findings emphasize the critical role of FCI and molecular studies in distinguishing AML from B-ALL or mixed phenotype acute leukemias.

Hence, this minimalistic approach may be further validated in future studies. The online version contains supplementary material available at 10.1007/s12288-025-01968-2.

KLC2-MT overexpression in BCR::ABL1-positive K562 and KU812 CML cells promoted cell proliferation and clonogenic potential, decreased imatinib sensitivity, and reduced apoptosis...KLC2-WT and KLC2-MT interacted with mothers against decapentaplegic homolog 2 (SMAD2); however, the latter impaired transforming growth factor-beta (TGF-β)-mediated SMAD2/3 activation while enhancing STAT3 phosphorylation. This study demonstrates the biological and functional importance of KLC2 mutation in CML cells, potentially enabling the development of better treatment strategies for CML patients carrying KLC2 mutations and providing enhanced understanding of the disease progression.

CD97, CD73, CD86, and CD58 are the best amongst newer markers in B-ALL MRD assessment. Our findings support integrating these into MRD panels to enhance post-therapy MRD detection, thus improving prognostication and guiding treatment decisions.

The incorporation of gene expression analysis, with confirmation using orthogonal methods, may help improve diagnostic yield. Developing practice guidelines will help harmonise reporting content and minimise interlaboratory variations.
