近年来,随着周围环境的恶化,肺癌的发病率最高并且呈现逐年上升的趋势,且其早期表现隐匿,很容易被忽视,很多患者确诊时已属晚期,丧失去了治疗的最佳时机。.本文主要总结和比较了几种传统的肺癌诊断方法如X线片、CT、MRI、PET-CT,并介绍了几种肺癌的最新的诊断技术,比如肺泡灌洗液或血清肿瘤标记物的联合检测、呼出气中的有机化合物的构成分析以及纤维支气管镜镜检技术等。上述方法诊断肺癌的敏感性和特异性各有优势,临床医生在临床工作中应合理应用上述检测方法,必要时联用多种检测手段,尤其要重视支气管肺泡灌洗液癌胚抗原如Cyfra21-1和CEA的联合检测,利用其较高的敏感性以提早发现和诊断肺癌。
In recent years, with the deterioration of the surrounding environment, the incidence of lung cancer is the highest and shows an increasing trend year by year. Moreover, its early manifestation is easily overlooked. Many patients are diagnosed late and lose the best chance of treatment. In this paper, we summarize and compare several traditional diagnostic methods of lung cancer such as X-ray, CT, MRI and PET-CT and introduce the latest diagnostic techniques of lung cancer such as alveolar lavage fluid or serum tumor markers Joint detection, exhaled breath in the composition of organic compounds and fiberoptic bronchoscopy techniques. The above method to diagnose the sensitivity and specificity of lung cancer have their own advantages. Clinicians should apply the above detection methods in clinical work, if necessary, combined with a variety of detection methods, with particular attention to bronchoalveolar lavage fluid carcinoembryonic antigen such as Cyfra21- 1 and CEA joint detection, the use of its higher sensitivity to early detection and diagnosis of lung cancer.
