多种活检在周围型肺癌诊断中的应用

目的研究CT引导下经皮肺活检（CT-PLB）与经支气管镜肺活检（TBLB）或经支气管针吸活检（TBNA）在周围型肺癌诊断中的应用。方法对143例周围型肺癌患者的诊断方法进行分析,其中137例通过单用或联合采用CT-PLB、TBLB、TBNA等检查手段取得病理学诊断,6例为术后病理学诊断。结果 CT-PLB确诊率为85.4%,TBLB确诊率为68.4%,TBNA确诊率为80%,联合应用总确诊率为95.8%。结论对于肺周围型病变,根据病灶大小、位置、与胸壁距离、有否纵隔淋巴结转移等具体情况选择合适的活检方式可取得病理学诊断,多种方法联合应用可提高检出率。

Application of CT-guided percutaneous lung biopsy and transbronchial lung biopsy or transbronchial needle as-piration in the diagnosis of peripheral lung cancer

Objective To study the application of CT-guided percutaneous lung biopsy （CT-PLB） and transbronchial lung biopsy （TBLB） or transbronchial needle aspiration （TBNA） in the diagnosis of patients with peripheral lung cancer. Methods The diagnostic method of 143 patients with peripheral lung cancer were retrospectively analyzed, which included 137 cases of pathology confirmed by sin- gle or combination of CT-PLB, TBLB, and TBNA examination, and 6 cases of postoperative pathological diagnosis. Results The diagno- sis rate of CT-PLB was 85.4%, TBLB 68.4%, and TBNA 80% respectively. The total diagnosis rate of the joint application was 95.8%. Conclusion For peripheral pulmonary lesions, the pathological diagnosis can be confirmed by selecting the appropriate biopsy method according the lesion size, location, the distance to chest wall, and if it has mediastinal lymph node metastasis. The application of combined methods can improve the detection rate.
