对32例常规检查不能确诊的周围型肺肿块,采用不同导向经皮肺活检。结果25例由病理确诊,7例经冲洗液涂片及测定肿瘤标记物而确诊;肺癌16例,肺结核13例,肺炎3例。肺癌组冲洗液中癌胚抗原(CEA)、糖链抗原153(CA153)、非小细胞肺癌抗原(LTA)水平明显高于炎症组(分别为P<001,P<005,P<001)。表明B超导向经皮肺活检安全、方便、准确,冲洗液中多项指标联检能提高组织细胞学诊断率,弥补纤支镜检查的不足。
32 cases of routine examination can not be diagnosed peripheral lung mass, using different guided percutaneous lung biopsy. Results 25 cases were diagnosed by pathology, 7 cases were diagnosed by washing smear and tumor markers; 16 cases were lung cancer, 13 cases were tuberculosis and 3 cases were pneumonia. The levels of carcinoembryonic antigen (CEA), carbohydrate antigen 153 (CA153) and non-small cell lung cancer antigen (LTA) in the lung cancer group were significantly higher than those in the inflammatory group (P <0.001, P <005, P <001, respectively). That B ultrasound guided percutaneous lung biopsy safe, convenient and accurate, a number of indicators in the washing fluid joint examination can improve the rate of histological diagnosis of cytology to make up for the lack of bronchoscopy.
