In the TFR phase, MR4.0 rates at 12 months (Arm 1: 31.9%, Arm 2: 37.5%; p = 0.383) and 24 months (Arm 1: 29.4%, Arm 2: 30.8%) revealed no differences in TFR success between 2 and 3 years of nilotinib. Irrespective of the consolidation duration, switching to nilotinib 300 mg BID provided the opportunity to achieve TFR if patients were unable to reach stable DMR with first-line imatinib.

The case highlights how delayed recognition of clonal eosinophilia can permit extensive organ injury, whereas early molecular testing and prompt initiation of imatinib yield dramatic clinical and hematologic remission. Persistent hypereosinophilia, particularly with cutaneous or gastrointestinal involvement, should prompt evaluation for PDGFRA-rearranged disease to enable early intervention and prevent irreversible tissue damage.

In summary, this study shows the critical role of selective targeting of components of the HIF1α signaling pathway for the complete eradication of chronic myeloid leukemia cells.

While imatinib revolutionized first-line therapy, resistance and specific mutation profiles necessitate subsequent generations of tyrosine kinase inhibitors (TKIs). Second- and third-generation TKIs have transformed the management of advanced GIST, extending survival and offering mutation-specific precision therapy. Ongoing research into resistance mechanisms, combination strategies, and novel inhibitors promises further optimization of patient-centered care.

Low-dose dasatinib is effective and tolerable in imatinib-resistant CML-CP, with nearly two-thirds achieving DMRs. Predictive biomarkers (T315I mutation, high ELTS risk, high baseline BCR-ABL1) can guide dose optimization.

Furthermore, patients with high serum IgG levels experienced significant therapeutic benefits. Our data show that local adaptive immunity dominated by TLS is a key factor in the efficacy of targeted therapy, and suggest that inducing IgG could be a feasible strategy for improving the prognosis of patients with GIST.

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.

Treatment of SUP-B15 cells with dexamethasone (Dex), Imatinib, or their combination significantly suppressed proliferation and promoted apoptosis, which was accompanied by increases in intracellular ATP, calcium, and glucose. Our findings indicate that P2RX1 may exert this function through modulating energy metabolism and calcium homeostasis, resulting in elevated intracellular calcium levels. Sustained elevation of calcium promotes apoptosis, whereas exogenous ATP activates P2RX1, enhances calcium influx, and attenuates the suppression of apoptosis associated with P2RX1 underexpression, ultimately correlating with improved treatment response.

Although Gleevec has been transformative for CML, blast crisis CML remains relatively drug resistant...These data suggest that MSI2-HOXA9 acts, at least in part, by increasing expression of the mitochondrial polymerase POLRMT and augmenting mitochondrial function and basal respiration in blast crisis. Collectively, our findings demonstrate for the first time that translocations involving the stem and developmental signal MSI2 can be oncogenic and suggest that MSI, which we found to be a frequent partner for an array of translocations, could also be a driver mutation across solid cancers.

Because of failure of imatinib therapy and multiple transarterial embolization procedures, sunitinib therapy was initiated, stabilizing the disease for nine months. Sunitinib therapy in NF1 patients requires strict blood pressure control. Additionally, pre-treatment vascular screening with CT angiography may be warranted.

SiRNA-mediated FN1 knockdown reduced the cell's susceptibility to all generations of TKIs employed in treatment of CML, including asciminib...Clinically, deregulation of FN1 was also observed in peripheral blood cells derived from CML patients. Our data indicate that FN1 may serve as a potential therapeutic target to address TKI resistance or as a suitable biomarker for the treatment.
