周围型肺癌经X线摄影、气管镜等检查仍不能确诊或即使确诊,但组织类型不明时,可经皮肺穿刺行细胞学检查。本文中有40例临床肺癌有36例经本法检出,无一例假阳性。癌细胞的检出率随穿刺次数的增加而递增。癌细胞分型以鳞癌及小细胞癌较准确,腺癌细胞分型误差较大。肿瘤较大者易于检出癌细胞。在73人次穿刺中有4例发生少量气胸(2例经对症处理),2例咯血,1例肋间神经痛,均自行痊愈。
Peripheral lung cancer can still be diagnosed by X-ray photography, tracheoscope, etc., or even if confirmed, but when the tissue type is unknown, cytology can be performed by percutaneous lung puncture. In this article, 40 cases of clinical lung cancer have been detected by this method, and 36 cases have no false positives. The detection rate of cancer cells increases with the number of punctures. The classification of cancer cells is more accurate in squamous cell carcinoma and small cell carcinoma, and the type of adenocarcinoma cells has larger errors. Larger tumors are easy to detect cancer cells. Among the 73 punctures, 4 cases had a small amount of pneumothorax (2 cases were treated symptomatically), 2 cases had hemoptysis, and 1 case had intercostal neuralgia, all of which healed on their own.
