Activating mutations in the epidermal growth factor receptor (EGFR) are present in approximately 15% of US patients with lung adenocarcinoma. EGFR tyrosine kinase inhibitors are associated with high response rate and progression-free survival for patients with non-small cell lung cancer with this genotype. Gefitinib, erlotinib, and afatinib are the EGFR tyrosine kinase inhibitors that are presently in clinical use. Understanding resistance mechanisms has led to the identification of a secondary mutational target, T790M, in more than half of patients, for which osimertinib has been approved. This article reviews the current treatments, resistance mechanisms, and strategies to overcome resistance.

Marine heatwaves are starting to occur several times a decade, yet we do not understand the effect this has on corals across biological scales. This study combines tissue-, organism-, and community-level analyses to investigate the effects of a marine heatwave on reef-building corals. Adjacent conspecific pairs of coral colonies of and that showed contrasting phenotypic responses (, bleached .

Introduction: Non-small cell lung cancer (NSCLC) constitutes approximately 80-85% of cancer-related fatalities globally, and direct and indirect comparisons of various therapies for NSCLC are lacking. In this study, we aimed to compare the efficacy and safety of immune checkpoint inhibitors (ICIs) in patients with epidermal growth factor receptor (EGFR)-mutated NSCLC.
Methods: The electronic databases were systematically searched from inception until March 18, 2024.

The search for effective anti-cancer therapies has led to the exploration of dual inhibition strategies targeting multiple key molecular pathways. In this study, we aimed to design a novel candidate capable of dual inhibition targeting both EGFR (Epidermal Growth Factor Receptor) and PARP-1 (poly(ADP-ribose)polymerase-1), two crucial proteins implicated in cancer progression and resistance mechanisms. Through molecular hybridization and structure-based drug design approaches, we synthesized a series of compounds based on spirooxindole with triazole scaffolds with the potential for dual EGFR and PARP-1 inhibition.

Traditional treatments such as radiotherapy and surgery offer limited clinical benefits and are often accompanied by cognitive dysfunction and a decline in quality of life. In recent years, novel small molecule tyrosine kinase inhibitors targeting epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), and other pathways have been developed, effectively penetrating the blood-brain barrier while enhancing intracranial drug concentrations and improving patient outcomes.

Background: First-line treatment for advanced gastric adenocarcinoma (GAC) with human epidermal growth factor receptor 2 (HER2) is trastuzumab combined with chemotherapy. In clinical practice, HER2 positivity is identified through immunohistochemistry (IHC) or fluorescence in situ hybridization (FISH), whereas deep learning (DL) can predict HER2 status based on tumor histopathological features. However, it remains uncertain whether these deep learning-derived features can predict the efficacy of anti-HER2 therapy.
