β-catenin plays an important role in acquired resistance to EGFR-TKIs in NSCLC cell lines and may be a potential therapeutic target for NSCLC patients who have failed to respond to targeted therapy.
YPEL1 and YPEL5 may be related to the action of erlotinib, and down-regulation of ITGA2 may be associated with the development of acquired resistance to erlotinib in EGFR-mutant NSCLCs.
Yet 4 large randomized phase III trials of chemotherapy with or without an EGFR tyrosine kinase inhibitor in unselected patients with advanced-stage NSCLC, altogether totaling > 4000 patients, did not demonstrate improvement in clinical outcomes with the combination.
Yes-associated protein 1 (YAP1), a main effector of the Hippo pathway, is associated with adverse prognosis and disruption of EGFR TKI modulation of non-small cell lung cancer.
WSE was associated with NSCLC and adenocarcinoma histology, and was also more frequently associated with epidermal growth factor receptor-mutations than cigarette-smoking patients were (50.0% cf.
Within the power of this study, our findings suggest that the selected polymorphic variants in the estrogen biosynthesis and metabolism pathways are unlikely to be major genetic modifiers of the prevalence of EGFR-mutant NSCLC.
With the increased availability of EGFR-targeted therapy options, nonresectable, multifocal NSCLC with diverging KRAS and/or EGFR mutations are likely to show different treatment responses, underlining the need to separately analyse multifocal tumours.
With the above paradoxical evidence, it is prudent to understand the prognostic significance of baseline CEA in patients with EGFR-mutant NSCLC treated with first-line EGFR-TKIs.
With prolonged follow-up, first-line pembrolizumab monotherapy continues to demonstrate an OS benefit over chemotherapy in patients with previously untreated, advanced NSCLC without EGFR/ALK aberrations, despite crossover from the control arm to pembrolizumab as subsequent therapy.
With human serum samples, the compact SPR biosensor detected similar levels of exosomal EGFR in NSCLC patients and normal controls, and higher expression of exosomal PD-L1 in NSCLC patients than normal controls.
Whilst cytotoxic chemotherapy has been the backbone of advanced non-small cell lung cancer (NSCLC) treatment for decades, the development of targeted agents for driver mutations such as EGFR, ALK, BRAF and ROS1 has changed the treatment paradigm and natural history of this disease.
While these preliminary data open a new exciting scenario for the future development of anti-EGFR therapies in NSCLC, ongoing afatinib trials will definitively establish a role for this molecule in the treatment of advanced NSCLC.
While epidermal growth factor receptor and anaplastic lymphoma kinase inhibitors are only applicable to a minority of patients and benefits are almost invariably short-lived, current studies indicate that at least 50% of patients with NSCLC have a targetable mutation.
Which treatment is preferred for advanced non-small-cell lung cancer with wild-type epidermal growth factor receptor in second-line therapy? A meta-analysis comparing immune checkpoint inhibitor, tyrosine kinase inhibitor and chemotherapy.
Whether WBRT plus EGFR-TKIs has a greater survival benefit than EGFR-TKIs alone or WBRT alone remains controversial in NSCLC patients with multiple brain metastases.
Whether this process plays a role in epidermal growth factor receptor-tyrosine kinase inhibitors resistance in non-small-cell lung cancer has not been studied extensively.
When KRAS, PIK3CA, MET, and non-sensitizing EGFR mutations are concomitant, up to 96.0% of NSCLC patients unlikely to respond to TKIs can be identified, and they represented independent negative prognostic factors.
