经支气管针吸活检在肺癌分期中的作用

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42例肺癌手术前X线和/或胸部CT疑有淋巴结转移的病例行TBNA并与手术后病理检查结果进行对比。结果 术前经TBNA证实N2淋巴结癌转移10例，术后病理检查全为N2阳性且与术前TBNA检查结果相符，术前经TBNA证实N1癌转移19例，术后病理阳性22例，TBNA假阴性3例，术前经TBNA后c-TNM分期与p-TNM分期对比正确率达85.7%(36/42)。全组仅有3例患者接受TBNA后有少量咯血，无气胸及其他严重并发症发生。结论 经TBNA进行肺癌分期方法简便，经济实用，其分期正确率高，有较高的临床应用价值。

The role of transbronchial needle aspiration in the staging of bronchogenic carcinoma

Objective To explore the role of transbronchial needle aspiration (TBNA) in the staging of bronchogenic carcinoma. Methods To 42 cases of primary bronchogenic carcinoma with suspected lymph node metastasis by X ray and CT scan of chest, the TBNA was performed before operation. The cytological results and c TNM by TBNA were compared with the pathological ones and p TNM after operation. Results The diagnosis of 10 cases with N 2 metastasis was completely corresponding by TBNA and pathological examination after operation. Nineteen out of 22 cases with N 1 metastasis were confirmed by TBNA, and the false negative results ocurred in 3 cases. The results of TBNA in lymph nodes' size from 2 to 3 cm was completely accordant with pathological ones after operation. For 1 to 2 cm lymphnodes, the accurate rate of TBNA was 88.5% (23/26). The overall accurate rate of c TNM by TBNA was 85.7% (36/42) compared with p TNM. A small amount of hemoptysis ocurred in 3 cases, no pneumothorax and other serious complications were observed. Conclusion The TBNA for staging of bronchogenic carcinoma is a simple and economic method with high correct rate and high clinical applicable value.
