In 2021, the US Preventive Services Task Force (USPSTF) called for increased efforts at tobacco control, smoking-cessation treatments, and annual lung cancer screening with low-dose computed tomography (LDCT), targeted at high-risk populations. In January 2024, the American Cancer Society (ACS) published an update on the previous 2013 lung cancer screening guidelines and recommends annual lung cancer screening with lung LDCT for individuals aged 50-80 years who are asymptomatic but who currently smoke or have previously smoked. Although rates of tobacco smoking have been falling in some countries, the incidence of lung cancer in individuals who have never smoked now represents the 7th most common cancer and the 5th leading cause of cancer-related death. Because there is evidence that lung cancer screening with LDCT reduces lung cancer mortality in individuals with a substantial smoking history, there is now increasing interest in evaluating LDCT for lung cancer screening in those who have never smoked. In 2024, the International Association for the Study of Lung Cancer (IASLC) published a five-year (2023-2027) roadmap for the global use of LDCT in screening for lung cancer. This editorial aims to highlight some recent guidelines and current approaches to lung cancer screening in smokers and non-smokers.
2021年，美国预防服务工作组（USPSTF）呼吁加大烟草控制、戒烟治疗力度，并针对高危人群开展年度低剂量计算机断层扫描（LDCT）肺癌筛查。2024年1月，美国癌症协会（ACS）发布了对上一版2013年肺癌筛查指南的更新内容，建议对年龄在50至80岁、无症状但目前吸烟或曾经吸烟的个体进行年度LDCT肺癌筛查。尽管一些国家的吸烟率一直在下降，但从不吸烟个体的肺癌发病率目前已成为第七大常见癌症和第五大癌症相关死亡原因。由于有证据表明，LDCT肺癌筛查可降低有大量吸烟史个体的肺癌死亡率，因此目前越来越多的人关注评估LDCT在从不吸烟人群中的肺癌筛查效果。2024年，国际肺癌研究协会（IASLC）发布了一份关于全球使用LDCT进行肺癌筛查的五年（2023 - 2027年）路线图。本社论旨在强调近期一些关于吸烟者和非吸烟者肺癌筛查的指南及当前方法。
