[Progress in the Study of Mechanisms Clinically Relevant to Insulin Resistance 
and Lung Cancer]

At present, the incidence and mortality rates of lung cancer rank top among malignant tumors. The early diagnosis, treatment and drug resistance of lung cancer still remain as problems in the management of lung cancer. Researchers are dedicated to identifying reliable biomarkers as predictive indicators or effective therapeutic targets for lung cancer. Insulin resistance (IR), a disorder characterized by reduced biological activity of insulin, leads to increased insulin secretion. In recent years, more and more studies have revealed the association between IR and the occurrence and development of cancer, with the insulin/insulin-like growth factor signaling pathway possibly playing a crucial role. In this article, we will focus on the relationship between IR and lung cancer, explore the impact and mechanism of IR on the development, progression and drug resistance of lung cancer. It may guide the development of new predictive tools and therapeutic strategies, and provide new ideas for research dedicated to reducing the incidence and mortality of lung cancer.
