摘要
肺腺癌的发病率逐年升高,已成为最常见的肺癌组织学类型,2011版国际肺腺癌新分类法废除了传统支气管肺泡癌的命名,并提出了原位腺癌的概念。目前,低剂量CT是临床筛查及诊断肺癌的重要方法。早期肺腺癌在CT上主要表现为磨玻璃结节,且不同时期的肺腺癌结节其影像特征不一,CT诊断主要依据病灶的形态学特征,主要包括结节的大小、内部结构、边缘及与邻近结构关系等。收集和分析了近年有关磨玻璃结节各CT征象在诊断不同时期肺腺癌价值的有关文献,并对其进行综述。
The incidence of lung adenocarcinoma is continuously increasing, and it has become the most common type of lung cancer. The concept of alveolar cell carcinoma has been abandoned and adenocarcinoma in situ has been prosed by the 2011 New Lung Adenocarcinoma Multidisciplinary Classification. The importance of computed tomographic （CT） in the screening and diagnosis of early lung adenocarcinoma has been emphasized. Early lung adenocarcinoma usually presents as a ground-glass nodule （GGN） on CT. The diagnosis is based on the morphological characteristics of lesions, mainly including size of nodule, internal structure, edge, and relationship with the adjacent structure, etc. In this article we reviewed the recent literatures concerning the value of GGN CT findings in diagnosing lung adenocarcinoma in early stage.
