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 investigate the accuracy of chest X-ray, high-resolution CT, fiberoptic bronchoscopy, serum tumor markers and sputum exfoliative cytology in the diagnosis of peripheral lung cancer and their complementary advantages under combined application. Methods: A retrospective analysis of our hospital trans-thoracic X-ray showed peripheral pulmonary lesions in patients with 823 cases of different methods of positive predictive value of comparative analysis. Results: The positive predictive value of different methods in diagnosing peripheral lung cancer were: chest radiograph: 47.24%; HRCT: 95.77%; fibrobronchoscopy: 32.45%; sputum exfoliated cells examination: 12.83%; serum tumor markers: 81.43 %; Joint examination: 92.12%. Conclusion: There are several advantages of each examination methods can not phase, replace each other, joint detection, complementary advantages, can greatly improve the diagnostic accuracy of primary lung cancer and tumor classification.
