低剂量CT引导肺活检对肺炎型肺癌的诊断价值

目的 评价低剂量CT(low-dose CT,LDCT)引导经皮肺穿刺活检对肺炎型肺癌(pneumonic type carcinoma of lung,PTCL)诊断的临床价值.方法 对2008年1月～2012年8月13例首诊为肺部感染性病变,后经病理证实为PTCL的临床资料进行回顾性分析.结果 LDCT引导肺活检均取得较理想的组织标本,操作时间14 ～ 29 min,平均21.5 min.9例(69.2％)发生并发症:6例(46.2％)气胸,3例(23.1％)咯血.肺活检病理:13例均为腺癌.7例胸腔镜术后病理:微浸润性腺癌2例,浸润性腺癌5例.结论 LDCT引导经皮肺穿刺活检对PTCL的定性诊断有重要价值.

Diagnostic Value of Low-dose CT-guided Transthoracic Needle Lung Biopsy in Pneumonic-type Lung Carcinoma

Objective To evaluate the clinical value of low-dose CT （LDCT）-guided transthoracic needle lung biopsy for diagnosis of pneumonic type carcinoma of lung （ PTCL）. Methods A retrospective analysis was made on the clinical data of 13 patients diagnosed as pulmonary infectious disease during the first visit, and confirmed by pathology as PTCL from January 2008 to August 2012. Results Ideal tissue samples were obtained by LDCT-guided transthoracic needle biopsy. The procedure was completed in a mean time of 21. 5 rain （ range, 14 - 29 min）. Nine patients （69. 2% ） developed postoperative complications, including pneumothorax （6 cases, 46.2% ） and asymptomatic hemoptysis （3 cases, 23. 1% ）. Lung biopsy histological diagnosis showed all 13 cases were adenocarcinoma. Postoperative pathological examination of 7 cases of vldeo-assisted tboracoscopic surgery showed microinvasive adenocarcinoma in 2 cases and infiltrating adenocarcinoma in 5 cases. Conclusion LDCT-guided transthoracic needle lung biopsy has significant value for the qualitative diagnosis of PTCL.
