We reviewed the records of 12 patients with primary tracheobronchial tumors and various clinical characteristics treated at our institution to investigate our overall management experience with disease. Over a 21-year period, we treated 1405 cases of primary pulmonary neoplasms, of which 12 (0.9%) patients had primary tracheobronchial tumors with eight different histological types, including three adenoid cystic carcinomas, two bronchial carcinoids, two papillomas, one squamous cell carcinoma, one mucous gland adenoma, one inflammatory pseudotumor, one schwannoma, and one mucoepidermoid carcinoma. Eleven of the patients had symptoms of airway obstruction and/or secondary infection or bleeding. A complete resection was performed in ten, which included a sleeve lobectomy in seven, sleeve pneumonectomy in one, tracheal resection in one, and left main stem resection without lung resection in one. Median survival following complete resection was 91 months. When possible, a complete resection provides the best potential benefits and symptomatic relief for patients with tracheo-endobronchial tumors. Further, various options related to tracheobronchoplasty including conservative resection can be applied for surgical intervention.
