| Abstract: | From January, 1961, to July, 1985, 50 patients in the Peking Union Medical College Hospital with intraluminal tracheobronchial tumors were operated on. There was no gender or age predominance either in the 24 patients with tracheal tumor or in the 26 patients with bronchial tumor. The 13 cell types found in these patients' specimens were divided into four groups: malignant, low-grade malignant, benign with tendency to recur and benign without tendency to recur. Squamous cell carcinoma and adenoid cystic carcinoma were the most common tumors of the trachea. Carcinoid and adenoid cystic carcinoma were the most common tumors of the bronchus in this group of patients. Conservative excision with postoperative irradiation may be sufficient for patients with advanced lesions of low-grade malignancy. |
