经支气管针吸活检对肺癌术前TNM分期与术后分期的对比分析

Comparative analysis of transbronchial aspiration and post-operative pathology in TNM staging of lung cancer

目的探讨经支气管针吸活检(TBNA)在肺癌分期中的临床应用价值。方法对2002年1月至2004年8月间术前胸部CT疑有淋巴结转移的46例肺癌病人行TBNA检查94组纵隔淋巴结并与术后病理检查结果进行对比。结果术前TBNA后cTNM分期与术后pTNM分期对比正确率达86.9%(40/46),全组病人TBNA后均未发生严重并发症。结论经TBNA进行肺癌分期方法简便、安全,经济实用,分期正确率高,具有较高的临床实用价值。

Objective To evaluate the clinical value of transbranchial needle aspiration (TBNA) in the pre-operative staging of lung cancer.Methods From January 2002 to August 2004, TBNA was performed preoperatively in forty-six cases of primary lung cancer with suspected lymph node matastasis examined by chest CT-scan. Cytological examination of ninety-four groups mediastinal nodes in these patients were compared with post-operative pathology in TNM staging.Results The accuracy of TBNA was 86.9%(40/46), as compared with post-operative pathology. No serious complications occurred during TBNA.Conclusion TBNA for the staging of lung cancer is a safe simple and economic method with high accuracy and high clinical application value.[
