Primary and acquired MET mutations in NSCLC exhibit distinct genomic characteristics. Patients harboring concurrent EGFR mutations in NSCLC may derive less benefit from MET-TKI and ICI, whereas those harboring TP53 co-mutations tend to experience more favorable outcomes compared with TP53 wild-type NSCLC patients when treated with MET-TKI.
Furthermore, evaluation of 7c in HCC827 (exon 19 deletion) mutation, which is a cell model highly sensitive to tyrosine kinase inhibitors, showed that the tested compound exhibited lower inhibition than erlotinib...Furthermore, 7c caused an increase in the levels of caspase 3 (4.68 folds) and caspase 9 (4.54 folds) in HCT-116 cells. Additionally, in silico studies of 7c showed a plausible binding mode that correlates with its potent inhibitory activity against the two enzymes, whereas ADME prediction revealed a favorable oral absorption.
Most patients preferred atezolizumab SC regardless of baseline characteristics, mean injection duration, and cumulative number of SC injections. The trend for a stronger preference was higher among patients who preferred SC than those who preferred IV. Our findings suggest that the proportion of preference for atezolizumab SC over IV is highest in patients aged > 74 years, and that administrator's experience could be an important factor influencing patient preference.
Several molecular mechanisms that can drive SCLC transdifferentiation have been identified. The treatment of transdifferentiated SCLC remains a significant challenge, although promising new strategies are currently under investigation. This review summarizes the current understanding of SCLC transdifferentiation.
Furthermore, patients with EGFR-mutant lung adenocarcinoma undergoing treatment with EGFR tyrosine kinase inhibitors exhibited a significantly extended survival rate compared with those with wild-type EGFR receiving chemotherapy. In conclusion, the present study demonstrated that immunohistochemistry with pleural effusion cell blocks can aid in clarifying the histological subtype of lung cancer, and enable EGFR mutation detection, which can effectively guide molecular targeted therapy.
We designed and synthesized a series of highly potent degraders based on the first-generation EGFR-TKI gefitinib and a cereblon (CRBN) ligand...In the HCC827 cell-derived xenograft model, compound 14 demonstrates substantial anti-tumor activity and effectively reduces EGFRDel19 protein levels in vivo. With its low molecular weight and excellent in vitro and in vivo efficacy, compound 14 could serve as a promising lead for developing degrader-based therapies targeting mutated EGFR.
We found that HPV infection and EGFR mutations seem to play opposite roles in ISP malignant transformation. HPV infection is a possible etiology of ISP and is also associated with its malignant transformation. EGFR mutations in ISP demonstrate prognostic significance with EGFR wild-type ISP being associated with earlier progression to SNSCC. Our meta-analysis demonstrates that there is not mutually exclusive between HPV infection and EGFR mutations in ISP. The result suggests that both HPV infection and EGFR mutations should be considered in the management of ISP.
This case illustrates the clinical value of liquid biopsy in detecting actionable mutations in patients with mixed histological lung cancers where tissue-based testing is inconclusive. Liquid biopsy enabled a personalized therapeutic approach without the need for further invasive procedures. Such strategies may be essential in managing histologically and genomically heterogeneous tumors.
The debate over STAS as a true invasion mechanism versus an artifact from surgical handling underscores the need for standardized pathological evaluation. This review aims to refine STAS detection, integrate it into multidisciplinary treatment decision-making, and assess its potential as a staging criterion in lung cancer management.
