    Journal: Lung; 2016 Dec; 194(6):905-910. PubMed ID: 27544227.
    Abstract:
    PURPOSE: Bronchoscopic biopsy of pulmonary carcinoid tumors has been controversial, and no study to date is dedicated to investigate diagnostic yield or safety. We reviewed our single center experience with pulmonary carcinoid tumors over a 10-year time period and assessed the diagnostic yield and safety of bronchoscopic biopsy of these tumors. METHODS: A retrospective analysis was conducted of all bronchopulmonary carcinoid tumors from January 2003 through January 2014 for patients treated at or referred to our tertiary care facility, including patient and tumor characteristics, diagnostic yield, and complications of bronchoscopy. RESULTS: Forty-nine patients with bronchopulmonary carcinoid tumors were identified. 75.5 % of our patients were female, and the median age was 60.7 years. 85.7 % patients were white, and 53.1 % were smokers. 83.7 % had typical carcinoid tumors or tumorlets, and 85.7 % had centrally located tumors. The median tumor size was 2.0 cm. Thirty patients underwent bronchoscopy for diagnostic evaluation. 76.7 % were diagnosed via bronchoscopic biopsy. Bronchoscopic yield was calculated at 65.7 % yield, and two complications of moderate to severe bleeding occurred with no emergent thoracotomies, transfusions, or deaths. No other complications occurred from bronchoscopy. CONCLUSION: The diagnosis of pulmonary carcinoid tumors via bronchoscopic biopsy is safe and effective, and bronchoscopy is recommended as the initial diagnostic modality for these tumors.
