肺腺癌新分类与低剂量螺旋CT诊断价值

New Classification of Lung Adenocarcinoma and Diagnostic Value of Low-dose Spiral CT

国际肺癌研究学会(IASLC)、美国胸科学会(ATS)、欧洲呼吸学会(ERS)三大机构联合发布了2011年版《肺腺癌的国际多学科新分类方案》。2015年WHO根据2011版新分类进行了相应更新,专家推荐低剂量(螺旋)CT(low-dose CT,LDCT)作为肺磨玻璃结节的筛查工具,强调尽可能在薄层图像上观察实性成分含量,观察有无分叶、脐凹征、毛刺、胸膜凹陷征、空泡征、空气支气管征等恶性征像,通过特征性影像表现判断肺腺癌亚型,为处理方式的选择提供参考以及判断预后等。综述肺腺癌新分类及LDCT影像的主要内容,供影像学医务人员及临床医生参考。

International Association for the Study of Lung Cancer(IASLC), American Thoracic Society(ATS) and European Respiratory Society(ERS) jointly released the 2011 edition of New International Multidisciplinary Classification Scheme for Lung Adenocarcinoma. In 2015, according to the new classification in 2011 edition WHO made the corresponding update. The experts recommended low-dose CT(LDCT) as the screening tool of pulmonary ground-glass nodules, and stressed that the content of solid components should be observed on the thin layer image. We should observe whether there are malignant characteristics, such as leaflet, notch sign, burr, pleural indentation, vocule sign or air bronchography sign. Through characteristic imaging performance, the subtype of lung adenocarcinoma should be judged, so as to provide a reference for the choice of the treatment method and judgment of prognosis. This paper reviews the new classification of lung adenocarcinoma and the main contents of LDCT imaging for the reference of medical personnel of imaging and clinicians.
