    Abstract:
    The objective of this article is to determine the relevance of close postresection surveillance for bronchopulmonary carcinoid. From 2006 to 2013, 57 patients underwent lung resection for bronchopulmonary carcinoid. They were assessed for effects of clinical presentation, subtype, stage, and tobacco use on survival and recurrence. Utility of bronchoscopy and radiographic surveillance was reviewed. Mean follow-up was 2.1 ± 1.7 years. Carcinoid patients presented at a young age (51 ± 15 years) with normal spirometry regardless of smoking status (forced 1-second expiratory volume, 88% ± 19% for never smokers vs 87% ± 16% for smokers). Thirty-nine patients underwent a lobectomy (2 sleeve resections) and 11 pneumonectomy or bilobectomy. Most carcinoids were of the typical (n = 53, 93%) rather than atypical (n = 4, 7.0%) subtype. Staging from pathology was unaffected by smoking status. Eight patients had positive lymph nodes at resection (13% of typical and 25% of atypical subtypes). One recurrence was an atypical pN0 carcinoid. Of 57 patients, 18 were surveilled postoperatively with bronchoscopy, which revealed no recurrences. Furthermore, 146 follow-up computed tomography scans were performed on 53 of 57 patients. No typical carcinoid recurrences were identified by any postresection surveillance technique, regardless of stage. Bronchopulmonary carcinoid is a different entity from non-small cell lung cancer and has low recurrence and mortality risks independent of smoking status. It is hard to justify close surveillance following complete resection of typical carcinoid. Computed tomography scans at 5-year intervals might be reasonable and more cost effective.
