Lung cancer has become the leading cause of cancer mortality globally, and 5-year survival rate is very poor. Screening and early detection are vital to improve survival and decrease mortality of lung cancer. In recent 20 years, low-dose spiral CT (LDCT) screening has become a research focus in this area. Randomized controlled trials have confirmed that LDCT can decrease lung cancer mortality. However, there are still some problems of LDCT. In this paper, we summarized the controversy that whether low-dose helical CT screening can reduce lung cancer mortality or not before its effectiveness was been confirmed, the results and problems in the randomized controlled trials and gave a prospect of low-dose helical CT screening's future application.
肺癌已成为全球癌症死亡的主要原因,其5年生存率很低。筛查和早期发现对于提高肺癌生存率和降低死亡率至关重要。近20年来,低剂量螺旋CT(LDCT)筛查已成为该领域的研究热点。随机对照试验已证实LDCT可降低肺癌死亡率。然而,LDCT仍存在一些问题。本文总结了在低剂量螺旋CT筛查有效性得到证实之前,其能否降低肺癌死亡率的争议、随机对照试验的结果及问题,并对低剂量螺旋CT筛查的未来应用进行了展望。
