摘　　要：肺癌是世界上最常见的恶性肿瘤,也是癌症相关死亡的主要原因。由于缺乏有效的早期诊断方法,肺癌预后较差,但与晚期肺癌相比,早期肺癌生存率大大提高。因此,早期诊断肺癌至关重要。作为一种主要的表观遗传学修饰,DNA甲基化在肺癌发生发展过程中发挥着重要作用。大量研究表明,抑癌基因甲基化检测是一种理想的肺癌早期诊断方法。随着检测技术的不断进步,可以实现多种基因的甲基化检测。研究发现多基因甲基化联合检测在穿刺病变组织、穿刺淋巴结组织等微创操作获取的组织样本以及外周血、支气管肺泡灌洗液、痰液等无创样本中均具有较高的检出率,并且较单一基因甲基化检测灵敏度及特异度更高,是一种理想的肺癌早期诊断方法。Lung cancer is the most common malignant tumor in the world and the leading cause of cancer-related death. Due to the lack of effective early diagnosis methods, the prognosis of lung cancer is poor, but compared with advanced lung cancer, the survival rate of early lung cancer is greatly improved. Therefore, early diagnosis of lung cancer is crucial. As a major epigenetic modification, DNA methylation plays an important role in the development of lung cancer. A large number of studies have shown that detection of tumor suppressor gene methylation is an ideal early diagnosis method for lung cancer. With the continuous improvement of detection technology, methylation detection of multiple genes can be achieved. And it is found that multi-gene methylation combined detection of tissue samples obtained by minimally invasive operation such as puncture of diseased tissue and puncture of lymph node tissue, as well as the noninvasive samples such as peripheral blood, bronchoalveolar lavage fluid and sputum have higher detection rate and higher sensitivity and specificity than single gene methylation. It is an ideal method for early diagnosis of lung cancer.
