A clinical study of resected adenoid cystic carcinoma of the tracheobronchial tree

From 1973 to 1990, 7 patients presented with a adenoid cystic carcinoma of tracheobronchial tree that was treated surgically. The locations were larger airways; 4 in the trachea, 1 in the carina, 2 in the basal bronchus. Surgical treatments were performed in all cases. The following resections were done: trachea only 3; carina 1; trachea plus larynx 1; left lower lobe (sleeve lobectomy) 1; left lung (pneumonectomy) 1. Except for tracheolaryngectomy and left pneumonectomy, all cases were undergone primary anastomosis. Operative death was only one patient who died of anastomotic separation. Irradiation was performed in 6 patients before or after operation. Two patients were died due to lung metastases or leukemia. According to the Kaplan-Meier's method, the 5 years survival rate of all patients was 68.6%. Our experience suggests that surgical treatment and adjunctive radiotherapy is beneficial in patients with adenoid cystic carcinoma.
