肺癌术前常规纵隔淋巴结外科分期的临床价值

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.
