肺癌筛查方法现状

Lung cancer is the leading cause of cancer mortality currently. 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.
