Abstract

PURPOSE:

We evaluated the characteristics of and treatment outcomes in patients with benign tracheobronchial tumors.

MATERIALS AND METHODS:

We reviewed the records of patients with benign tracheobronchial tumors who underwent bronchoscopic intervention with mechanical removal and Nd: YAG laser cauterization, and evaluated the characteristics and treatment outcomes of 55 patients with hamartomas, leiomyomas, papillomas, typical carcinoids, or schwannomas seen between April 1999 and July 2012.

RESULTS:

The most common tumors were hamartoma (n=24), leiomyoma (n=16), papilloma (n=7), typical carcinoid (n=5), and schwannoma (n=3). Forty-one patients (75%) had symptoms. On chest computed tomography, 35 patients (64%) had round or ovoid lesions, accompanied by atelectasis (n=26, 47%) or obstructive pneumonia (n=17, 31%). Fatty components (n=9, 16%) and calcifications (n=7, 13%) were observed only in hamartomas, leiomyomas, and typical carcinoids. At bronchoscopy, the typical findings were categorized according to tumor shape, surface, color, and visible vessels. Fifty (91%) patients underwent complete resection. Forty patients (73%) achieved successful bronchoscopic removal defined as complete resection without complications or recurrence. Recurrences occurred in four papillomas, one leiomyoma, and one typical carcinoid. The proportions of tumor types (p=0.029) differed between the successful and unsuccessful removal groups, and a pedunculated base (p<0.001) and no spontaneous bleeding (p=0.037) were more frequent in the successful removal group.

CONCLUSION:

We described clinical, radiological, and typical bronchoscopic findings in patients with benign tracheobronchial tumors; these findings might help to differentiate such tumors. Bronchoscopic intervention was a useful treatment modality, and tumor type, pedunculated base, and vascularity may influence successful tumor removal.
