Background:
Lung cancer is one of the leading causes of cancer mortality in the US. The use of precision medicine in the past 10 years has significantly changed the therapeutic landscape of lung cancer. Management of advanced non-small cell lung cancer (NSCLC) has transitioned from a chemotherapeutic approach to targeted treatments and immunotherapeutic agents. Several tyrosine kinase inhibitors (TKIs) have been approved for patients with targeted mutations while patients who do not have driver mutations; immunotherapy has been recently approved as frontline therapy,which has resulted in marked improvement in overall survival and added a new tool in our armamentarium.
