Abstract: Lung cancer is the leading cause of cancer-related mortality worldwide.Currently, epidermal growth factor receptor and anti-vascular endothelial growth factor receptor have become first-line clinical application.But the lung carcinoma can tend to be resistant of targeted therapies and radiation. The researches have found that PI3K/AKT/mTOR pathway widely exists in many kinds of cancer cells and it plays an important role in the process of cell growth,proliferation and angiogenesis.We find that the pathways is closely associated with tyrosine kinase inhibitor and radiation resistance.The PI3K/AKT inhibitor could reverse the drug resistance of epidermal growth factor receptor-tyrosine kinase inhibitor. The same as the mTOR inhibitor for the radiation sensitivity.These findings may provide basic evidence for PI3K/AKT inhibitor and mTOR inhibitor applied in the treatment of lung cancer.
