肺癌是最常见的起源于支气管粘膜或腺体的恶性肿瘤,其发病率和死亡率呈上升趋势,早期诊断是提高疗效的关键。至今尚无单项肿瘤标志物能有效地用于肺癌的早期临床诊断,探讨多项联合检测显得尤为重要。同时不同肿瘤标志物的检测还有助于区别肺鳞癌和腺癌。本研究对97例肺癌患者进 Lung cancer is the most common malignant tumor that originates from bronchial mucosa or gland. The incidence and mortality of lung cancer are on the rise. Early diagnosis is the key to improve the curative effect. So far no single tumor markers can be effectively used for early clinical diagnosis of lung cancer, to explore a number of joint testing is particularly important. At the same time the detection of different tumor markers also help to distinguish between squamous cell carcinoma and adenocarcinoma. The study of 97 patients with lung cancer into
