肺癌是肺部恶性肿瘤中的一种特殊类型。本文观察了将近3,000例肺癌,癌肉瘤8例,占0.27%。均经手术切除。主要临床表现为阻塞性肺炎的体征。6例作支气管镜检查,发现1例支气管内肿瘤阻塞左主支气管。作支气管镜活扦4例,1例阳性,但支气管吸引分泌物均未找到恶性细胞。5例作全肺切除,3例作肺叶切除。3例手术后半年内死亡,径尸体解剖证实有局部肿瘤复发和远处脏器转移,后 Lung cancer is a special type of lung cancer. This article has observed nearly 3,000 cases of lung cancer, 8 cases of carcinosarcomas, accounting for 0.27%. All have been surgically removed. The main clinical manifestations are signs of obstructive pneumonia. Six patients underwent bronchoscopy, and one case of bronchial tumor obstructed the left main bronchus. For bronchoscopic surgery in 4 cases, 1 case was positive, but no malignant cells were found in the bronchial suction secretions. Five patients underwent pneumonectomy and three patients underwent lobectomy. Three cases died within six months after surgery. The autopsy confirmed that there was local tumor recurrence and distant organ metastasis.
