经硬气管镜作隆突活检——不管隆突的外观是否有异常——已被证实为肺癌分期的有效方法。作者在给59例病人作纤维支气管镜检查时作隆突活检,每个病人用不同活检钳在隆突后部至少作2处活检。隆突有明显肿物侵犯者不包括在本组,纤支镜检查完全正常者不作活检。该检查无不良反应。59例中有5例为良性疾病,6例为组织学未能确定的恶性病。余48例经组织学诊断为肺癌,其中鳞癌30例,未分化癌8例,燕麦细胞癌7例,腺癌、腺鳞癌和大细胞癌各1例。48例中5例(10%)隆突活检发现异常,其中4 Hard tracheal biopsy - regardless of the appearance of the carina - has been proven to be an effective method for lung cancer staging. The authors performed a carotid biopsy on 59 patients undergoing fiberoptic bronchoscopy. Each patient had at least 2 biopsies at the back of the carina with different biopsy forceps. Those with a prominent hematoma in the carina were not included in this group. No biopsy was performed when the bronchoscopy was completely normal. There is no adverse reaction to this inspection. Of the 59 cases, 5 were benign and 6 were histologically unreliable malignancies. The remaining 48 cases were diagnosed as lung cancer by histological examination, including 30 cases of squamous cell carcinoma, 8 cases of undifferentiated carcinoma, 7 cases of oat cell carcinoma, and 1 case of adenocarcinoma, adenosquamous carcinoma and large cell carcinoma. Of the 48 cases, abnormalities were found in 5 cases (10%) of the carotid biopsy, of which 4
