MET (MET proto-oncogene, receptor tyrosine kinase)

MET amplification alters the balance of EGFR/MET/ERBB3 dimerization, leading to a shift in signaling dependence from EGFR to MET. These findings provide insight into therapeutic strategies for EGFR-mutated NSCLC.

These findings demonstrate that H. pylori can infect the 3D liver model and induce apoptosis and signaling alterations in hepatocytes, suggesting a potential pathological impact on the liver. Further studies are required to determine whether similar effects occur in the human liver in vivo.

In routine practice, first-line osimertinib shows robust effectiveness but lower rwOS than expected and substantial post-progression attrition. These findings underscore the need for risk-adapted treatment strategies and support prospective evaluation of OPD management approaches, including integration of LAT alongside contemporary systemic options.

On this basis, we developed IR788-Crizotinib, a c-Met-targeted near-infrared window-II (NIR-II) fluorescent probe, and evaluated its imaging performance in subcutaneous xenograft, 4-NQO-induced oral lesion, orthotopic tongue OSCC and lymph node metastasis mouse models...In cervical lymph nodes, it detected micro-metastatic foci as small as 342 μm, with 100% sensitivity. c-Met-targeted NIR-II imaging provides an integrated visualization strategy for premalignant lesion screening, primary tumor delineation and metastatic lymph node detection in OSCC, with translational potential for precision management of oral cancer.

Crizotinib showed no significant difference in progression-free survival (PFS) or overall survival (OS) between first-line and post-chemotherapy use (PFS: p = 0.803; OS: p = 0.761). For second-generation ALK-TKIs, first-line treatment had numerically longer PFS compared to post-chemotherapy (alectinib: 41 vs 24 months; ceritinib: 30 vs 8 months), but these differences were not statistically significant after adjustment (p = 0.120 and 0.284, respectively)...Among patients treated with alectinib, there appears to be a trend toward shorter PFS and OS in those with MET overexpression. In a limited number of matched samples, PD-L1 expression did not change significantly after TKI resistance, although a slight increase was observed.

Teliso-V monotherapy 1.9 mg/kg elicited durable responses, irrespective of the type of previous therapy received, and maintained a manageable safety profile in patients with c-Met protein overexpressing EGFR wild-type, nonsquamous NSCLC. NCT03539536.

EGFR tyrosine kinase inhibitors (TKIs) have transformed management, with first-line osimertinib demonstrating a median progression-free survival (PFS) of 18.9 months and overall survival (OS) of 38.6 months in the FLAURA trial...Understanding these mechanisms is critical for optimizing patient outcomes and guiding personalized therapeutic approaches. This review discusses current strategies to delay or overcome resistance and highlights emerging therapeutic avenues with the potential to reshape the management of EGFR-mutant NSCLC.

This comprehensive molecular profiling study illustrates the real-world utility and limitations of targeted next-generation sequencing of BTC and affirms the use of precision medicine in patients with these diseases. Characterization of genomic heterogeneity and therapeutic resistance has the potential to inform ongoing drug development efforts for BTC.

Rare actionable genomic alterations are recurrently identified in NGS-assessed NSCLC cohorts. These findings support the clinical value of broad genomic profiling, provide realistic expectations for diagnostic yield in routine practice, and may inform precision oncology implementation, molecular-testing pathways, and resource allocation.

These findings demonstrate that MET dysregulation is a recurrent molecular event in ampullary carcinoma and support further investigation of MET and HER2 co-expression as a basis for future mechanistic and therapeutic studies.

This report describes the first documented case of NK associated with Teliso-V therapy. The temporal association between Teliso-V exposure, bilateral corneal hypoesthesia, persistent epithelial defects, and concurrent peripheral neuropathy suggests a potential neurotoxic mechanism related to the drug's monomethyl auristatin E payload. Clinicians should maintain a high index of suspicion for NK in patients receiving ADCs who present with painless visual decline and corneal epithelial disease. Early diagnosis and prompt treatment with cenegermin may facilitate corneal healing and prevent vision-threatening complications.
