Early diagnosis is crucial to the good prognosis of lung cancer. Evidence has shown that low-dose computed tomography (CT) screening can make the decline in the mortality of lung cancer. However, there are still many problems in the screening, such as, high false-positive rates, overdiagnosis and radiation exposure. As another non-invasive tumor screening method, blood-based tumor markers showed a high sensitivity and specificity in early diagnosis of lung cancer in recent years. How to establish a comprehensive mode for lung cancer screening by use existing screening methods, we need more clinical research. %K Lung neoplasms %K Screening %K Low-dose computed tomography %K Circulating tumor cells %K Autoantibodies %U http://www.lungca.org/index.php?journal=01&page=article&op=view&path%5B%5D=10.3779%2Fj.issn.1009-3419.2016.10.14
