Abstract:
Targeted therapy has ushered in a new era of precision medicine for non-small cell lung cancer (NSCLC). Currently, epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) stand as the recommended first-line therapy for advanced NSCLC harboring sensitive EGFR mutations. Nevertheless, most patients inevitably confront the challenge of drug resistance. This phenomenon arises not solely from intrinsic alterations within cancer cells but also from the intricate dynamics of the tumor microenvironment and the complex interactions that occur between cancer cells and their immediate surroundings. This review consolidates the current knowledge regarding EGFR-TKI resistance mechanisms, with a specific emphasis on unraveling the role played by the tumor microenvironment. In addition, the review delineates strategic approaches to surmount TKI resistance, thereby enriching the understanding of the interplay between therapeutic agents and the intricate milieu surrounding cancer cells.
