为了早期发现和诊断≤2 cm 边缘型肺癌,本文分析了108例手术切除患者的术前确诊情况。男69,女39例,平均年龄59岁。其中腺癌91例、鳞癌9例,小细胞肺癌4例、大细胞肺癌3例、腺鳞癌1例。56例无转移,52例有远区或淋巴结转移.本组108例中101例经支气管检查作出诊断(用纤支镜者85例,Metras 导管16例),经皮针吸活检19例,另2例经痰检确诊.经纤支镜刮检的85例患者中,首次镜检取得阳性诊断者65例(76.5%),经数次镜检确诊者71/85例(83.5%)。凡癌瘤<1.1cm,用刮取方法取样时,透视的荧光屏上看不到肿瘤的影像,肿瘤位于胸膜下或肺外肿瘤压迫支气管者,这些经纤支镜刮检均达不 For the early detection and diagnosis of borderline lung cancer ≤2 cm, this article analyzed the preoperative diagnosis of 108 patients undergoing surgical resection. 69 males and 39 females, with an average age of 59 years. There were 91 cases of adenocarcinoma, 9 cases of squamous cell carcinoma, 4 cases of small cell lung cancer, 3 cases of large cell lung cancer, and 1 case of adenosquamous carcinoma. 56 cases had no metastases, 52 cases had distant metastasis or lymph node metastasis. 101 cases were diagnosed by bronchial examination (85 cases with fibrobronchoscopy and 16 cases with Metras catheter) in 108 cases. Percutaneous needle biopsy was performed in 19 cases. Two cases were confirmed by sputum examination. Of the 85 patients who were examined by fibrobronchoscopy, 65 (76.5%) were diagnosed positive by microscopy for the first time, and 71/85 (83.5%) were diagnosed by microscopy several times. When the tumor was < 1.1cm, the image of the tumor could not be seen on the fluoroscopy screen when sampling with the scraping method. The tumor was located under the pleura or the extrapulmonary tumor was oppressed by the bronchus.
