Lung cancer is the most common malignant tumor in the world. The five-year survival rate is 19.7%, which seriously threatens human health. Lung cancer screening is an effective measure to reduce lung cancer mortality. Existing studies have shown that screening with low-dose computed tomography (LDCT) can reduce lung cancer deaths by 20%. Currently, lung cancer screening is recommended internationally and nationally. Studying the development status of lung cancer screening helps us to identify the high-risk groups of lung cancer, explore reasonable screening programs, improve the cost-effectiveness of screening and reduce the economic burden. Therefore, this article summarizes the current status of lung cancer screening, the cost-effectiveness of lung cancer screening and the existing problems as follows. .
【中文题目：肺癌筛查研究进展】 【中文摘要：肺癌是世界上最常见的恶性肿瘤，其5年生存率仅为19.7%，严重威胁人类健康。肺癌筛查是降低肺癌死亡率的有效措施，已有的研究证明用低剂量螺旋计算机断层扫描（low-dose computed tomography, LDCT）进行筛查可降低20%的肺癌死亡，目前国际和国内均建议进行肺癌筛查。研究肺癌筛查的发展现状有助于我们明确肺癌的高危人群，探索合理的筛查方案，提高筛查的成本效益，减轻经济负担。因此本文就肺癌筛查现状、肺癌筛查的成本效益以及存在的问题综述如下。 】 【中文关键词：肺肿瘤；筛查；成本效益】.
