[The long-term outcome and prognostic analysis of surgically treated patients with trachea tumors]

To investigate and evaluate the clinical features, diagnostic methods, surgical management of trachea tumors in order to improve patients outcome.

Clinical data of 32 patients with trachea tumors surgically treated from June 1986 to June 2005 were retrospectively analyzed. There were 22 male and 10 female patients. The age ranged from 14 to 63 years old with a median of 48 years old. The surgical procedures performed were resection and reconstruction of trachea in 10 cases, right or left pneumonectomy and carinal resection and reconstruction in 8 cases, right sleeve upper lobectomy, carinal resection and reconstruction of trachea and carina in 8 cases, and carina resection and reconstruction with tumor removal through tracheal windows 6 cases. The tracheal defect was repaired with a Teflon flap in two patients. Cardiopulmonary bypass was used in 2 patients during surgery.

The histological examination of resected lesions revealed squamous cell carcinoma in 19 cases, adenoid cystic carcinoma in 8 cases, adenocarcinoma in 2 cases, carcinoid in 2 cases, leiomyosarcoma in 1 case and adenoma in 1 case. One case had infection of thoracic cavity and 3 cases experienced temporary cardiac arrhythmia. There was no operative death. The follow-up periods were from 5 months to 3 years. The 1, 2 and 3 year survival rates were 93.7%, 59.4% and 50.0% respectively.

Squamous cell carcinoma adenoid cystic carcinoma are the most common in trachea tumors. Preoperative bronchoscope examination and chest CT scan can provide valuable diagnostic data. Proper choice of surgical procedure is important for improved patients' outcome.
