Non–small cell lung cancer (NSCLC) accounts for 80%-85% of all lung cancers and nearly 25% of all cancer deaths, with adenocarcinoma, the predominant subtype. Patients with NSCLC often have no symptoms, and unfortunately often present initially with advanced disease, with only 20% of lung cancers presenting with localized disease. Thus, early detection through lung cancer screening in asymptomatic high-risk patients can offer a vital opportunity for early detection at an early stage with decreased mortality. Current recommendations include lung cancer screening using low-dose computed tomography for high-risk asymptomatic patients. The recommendations are on the basis of a regression risk model developed by the National Lung Screening Trial (NLST) Lung Screening Study (LSS) data and validated by NLST American College of Radiology Imaging Network data. The most common treatments for lung cancer include surgery, chemotherapy, radiation therapy, and/or targeted therapy, in combination or by themselves.
