CT导向纵隔淋巴结针吸活检对肺癌的诊断意义

目的探讨CT导向纵隔淋巴结经皮针吸活检对支气管肺癌的诊断意义.方法1992-10～1998-09期间随机选择142例临床疑为原发性肺癌并有纵隔淋巴结增大(直径≥10mm)的病例,在CT扫描监控下,使用国产秦氏针进行185次针刺活检与细胞学检查.结果经手术(98例)、尸检(6例)与1年以上随访(25例)证实敏感性为82%,特异性为100%.结论CT导向经皮针刺纵隔淋巴结活检是一简便而又可靠的诊断方法,对支气管肺癌的诊断与分期有重要价值.

CT Guided Percutaneous Needle Aspiration Biopsy of Mediastinal Lymph Nodes

Objective The purpose of this study was to evaluate the diagnostic significance of CT guided percutaneous needle aspiraion biospy of mediastinal lymph nodes for primary lung cancer.Methods 142 cases of clinical suspected N2-3 primary lung cancer were examined.After supine or prone posistioning,CT was performed with a 5 mm thickness and a 5 mm interval.Under local anesthesia,the enlarged mediastinal lymph node(>10 mm) was punctured,using intermittent CT monitoring and samples were studied cytologically.Results Node status was evaluated pathologically at operative resectic (98) or autopsy(6) or follow up(25) afterward.The overall sensitivity and specificity were 82% and 100% respectively.Conclusion CT guided percutaneous needle aspiration biopsy of mediastinal lymph is useful,less expensive an effective technique for diagnosis and staging of primary lung cancer.
