OBJECTIVETo explore the clinical experience of surgical treatment of primary malignant tumors of the trachea and main bronchus.

METHODSThe clinicopathological data of 18 patients with primary malignant tumors of the trachea and main bronchus surgically treated from February 1994 to August 2007 were reviewed retrospectively. The surgical management included sleeve tracheal resection in 8 cases, lower trachea and carina resection with carina reconstruction in 4 cases, local enucleation of the tumor in 4 cases, left or right carino-pneumonectomy and carina reconstruction in 2 cases, and resection of the tracheal or bronchial tumor and reconstruction of the airway under cardiopulmonary bypass in 6 cases.

RESULTSAmong the 18 cases, there were 7 adenoid cystic carcinomas, 9 squamous cell carcinomas, 1 lymphoepithelial-like carcinoma and 1 follicular non-Hodgkin lymphoma. All the cases recovered well except one who died of endotracheal bleeding and asphyxia at the 10(th) postoperative day.

CONCLUSIONSurgical resection is the most effective treatment for primary malignant tumors of the trachea and main bronchus. The selection of operation modes should be individualized according to patients' condition. Both complete resection and safety should be taken into consideration simultaneously.
