    Abstract:
    BACKGROUND AND OBJECTIVE: The aim of this study is the clinical value of preoperative routine surgical staging to mediastinal lymph nodes on lung cancer. METHODS: Seventy-six cases underwent lymph nodes biopsy with mediastinoscopy. The diagnostic efficacy of thoracic CT scan and mediastinoscopy on mediastinal lymph nodes metastasis were compared. RESULTS: The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of thoracic CT scan and mediastinoscopy on diagnosing mediastinal lymph nodes metastasis were 68.5%, 66.7%, 68.4%, 84.6%, 16.7% and 87.5%, 100%, 84.2%, 100%, 60%, respectively. CONCLUSION: Routine preoperative mediastinoscopy had obvious advantage compared with thoracic CT scan on mediastinal lymph nodes staging. The routine preoperative surgical staging of mediastinal lymph nodes on lung cancer had high clinical value. 背景与目的: 探讨肺癌术前常规纵隔淋巴结外科分期的临床价值。 方法: 76例肺癌患者开胸术前常规行纵隔淋巴结活检，以术后病理为金标准，比对术前胸部CT和纵隔镜对肺癌纵隔淋巴结转移的诊断效能。 结果: 术前胸部CT对纵隔淋巴结转移的诊断敏感性、特异性、准确性、阳性预测值和阴性预测值分别为68.5%、66.7%、68.4%、84.6%和16.7%。纵隔镜检查术则分别为87.5%、100%、84.2%、100%和60%。 结论: 肺癌术前常规纵隔镜检查术对纵隔淋巴结分期的优势明显，具有极高的临床实用价值。
