During a 17-year period

38 patients with primary tracheobronchial tumors received surgical treatment in PUMC Hospital. Arnong the 38. 12 had low-malignancy tracheal tumors

11 had benign tracheal tumors

14 had low malignancy bronchial tumors and 1 had a benign bronchial tumor. Fifteen operations were perforrned on 12 patients with low-malignancy tracheal tumors

including local resection of the tumor and tracheal wall in 4 and curettage of the tumor plus electrical cauterization in 10. Postoperative radiotherapy was used as an adjuvant treatment in 8 patients with adenocystic carcinoma. Eight patients have survived for more than 5 years and 3 patients have survived for longer than 10 years postoperatively. All 11 patients with benign tumors received curettage of the tumor and were followed up for an average of 6. 5 years. Among them

9 are still alive. Of the 14 patients with low malignancy bronchial tumors

5 underwent curettage of the tumor plus electrical cauterization through incision of the main bronchus or intermedial bronchus

and 7 underwent lobectomy or pneumonectomy. The authors conclude that the correct diagnosis rate can be increased by enhancing recognition of this disease and applying tracheal tomography and bronchoscopy.
