To investigate the clinical characteristics and treatment outcomes in Chinese pediatric and adolescent patients with primary tracheobronchial tumors by focusing upon the exploration of prognostic factors.
A retrospective review of medical records collected from January 1996 through June 2009 was conducted within a single institution, inclusive of the total 19 treated pediatric and adolescent patients (3 benign tumors, 16 malignant tumors). A parallel comparison of adult cases with tracheobronchial tumor was performed to the pediatric and adolescent cases.
The chart review of pediatric and adolescent case reports revealed 19 cases with primary tracheobronchial tumors. Final pathologic diagnosis included 14 (73.68%) mucoepidermoid carcinoma (ME), 2 (10.53%) carcinoid tumor, 2 (10.53%) papillomatosis and 1 (5.26%) neurofibroma. Median age upon diagnosis was 12 years (range 4–18 years). Chest imaging revealed common abnormal radiographic atelectasis (12/19). Patients with localized disease received surgical tumor resection. There were a total of 8 (42.1%) sleeve resections, 4 (21.1%) resection of anatomically related lung parenchyma (1 bilateral lobectomies, 2 lobectomies, 1 pneumonectomy) and 7 local tumor resections. No surgery-related deaths or complications were observed. 16 patients (84.2%) remained disease free with a median follow-up of 70.5 months (range 44–168 months).
Our hospital data indicated a high incidence of ME, presenting the difference in the incidence rates between Chinese and western populations. Sleeve lobectomy provides efficient treatment with excellent prognosis among Chinese pediatric and adolescent patients.
