不同检测方法对周围型肺癌诊断的意义

Diagnostic Value of Different Detection Methods for Peripheral Pulmonary Carcinoma

目的:探讨胸部X线片、高分辨CT、纤维支气管镜、血清肿瘤标记物及痰液脱落细胞学检查等几种方法在周围型肺癌诊断中的准确性以及联合应用情况下的优势互补性。方法:回顾分析我院经胸部X线片提示周围型肺部病变患者823例不同检查方法的阳性预测值对比分析。结果:不同方法诊断周围型肺癌的阳性预测值:胸部X线片:47.24%;HRCT:95.77%;纤维支气管镜检查:32.45%;痰液找脱落细胞检查:12.83%;血清肿瘤标记物:81.43%;联合检查:92.12%。结论:几种检查方法各有其优点不能相,互取代,联合检测,优势互补,可大大提高原发性肺癌诊断和肿瘤分型诊断的准确度。

Objective To evaluate the diagnostic value of peripheral pulmonary carcinoma by chest X - ray, HRCT, fibrobronchoscope tumor marker and sputum Cytology. Methods 427 cases of primary pulmonary cancer patients and 396 cases of benign lesion patients confirmed by pathology were reviewed and analyzed ret- rospectively from Septembe,2002 to September 2009. All cases had underwent chest X -ray, HRCT, flbrobron- choscope and sputum cytology. Results The masculine pretest of periheral pulmonary carcinoma by X - ray, H RCT, sputumcytology, fibrobronchoscopy, tumor marker was 47.24%, 95.77 %, 32.45 %, 12.83 % and 81. 43% , respectively. The masccline pretest of combined measuremen was 92.12%. Conclusion The serial test, chest X -ray, HRCT fibrobronchoscope tumor marker and sputum cytology can greatly improve the diagnostic accuracy of lung cancer.
