Low-dose CT screening for lung cancer is effective but expensive. Therefore, cheaper or more focused screening strategies may be required. LungSEARCH is a randomised prospective trial of 1568 high-risk individuals (ie, current or former moderate to heavy smokers with mild/moderate COPD) who undergo either annual sputum cytology/cytometry testing or no screening. Those with abnormal sputum then receive annual CT and fluorescent bronchoscopy for the remainder of 5 years, to identify early stage lung cancer. It is hoped that these simple initial tests could identify those requiring expensive CT scans, and the aim is to demonstrate a stage shift towards early stage cancers.Trial registration numbers

低剂量CT肺癌筛查有效但成本高昂。因此,可能需要更便宜或更具针对性的筛查策略。LungSEARCH是一项针对1568名高危个体(即目前或既往中度至重度吸烟者合并轻度/中度慢性阻塞性肺疾病)的随机前瞻性试验,这些个体要么接受年度痰细胞学/细胞计数检测,要么不进行筛查。痰检异常者在接下来的5年中每年接受CT和荧光支气管镜检查,以发现早期肺癌。希望这些简单的初始检测能够识别出需要进行昂贵CT扫描的人群,目标是证明向早期癌症的分期转变。试验注册号
