原发性肺肿瘤(肺癌)是当今危害人们健康最常见的恶性肿瘤之一,其中70％就诊时已是中晚期患者,失去了手术的机会,而早期发现和诊断可使肺癌患者的5年生存率提高到80％。因而肺癌的早期诊断至关重要。近年来,肿瘤标记物的研究和发展迅速,为肺癌的早期诊断提供了依据,但单项指标的检测仍有一定的局限性,因此学者们强调多项肿瘤标记物
Primary lung cancer (lung cancer) is one of the most common malignant tumors that endanger people’s health. Among them, 70% of patients are middle-late patients and have lost the chance of surgery. Early detection and diagnosis can make lung cancer patients 5 years. The survival rate increased to 80%. Therefore, early diagnosis of lung cancer is crucial. In recent years, the rapid development of tumor markers has provided a basis for the early diagnosis of lung cancer, but the detection of individual markers still has some limitations. Therefore, scholars have emphasized a number of tumor markers.
