title: [A study on low grade malignant tumors arisen in the trachea and the bronchus].
abstract: Twelve patients who suffered from low grade malignant tumors arisen in the trachea and the bronchus (6 of carcinoid, 4 of mucoepidermoid carcinoma, and 2 of adenoid cystic carcinoma) underwent surgical treatment from 1977 to 1996 in our department. Operations included 1 sleeve resection of the trachea, 1 patch plasty of the trachea, 3 sleeve lobectomies, and 7 lobectomies. Lymph node dissection was performed in 9 of 12 cases. Metastases in lymph nodes were not found in all 12 cases. Five year survival rate of low grade malignant tumors arisen in the trachea and the bronchus was 78.8% and better than that of stage I lung cancers.
