OBJECTIVES: At our institution, limited surgical techniques are reserved only for suspected typical carcinoids, and nodal dissection and multimodality therapy are frequently used for atypical carcinoids. We describe the results of these differing management strategies based on initial clinicopathologic characteristics. METHODS: Retrospective review of patients treated for thoracic carcinoid from 1995 to 2009. Information was abstracted concerning surgical and nonsurgical treatments, pathology results, and outcomes. Event-free and survival endpoints were compared. RESULTS: The median follow-up was 5.0 years (range, 0.5 to 17.4 y). Fifty-two patients underwent resection. The 5-year event-free survival for typical carcinoid patients was 88.2%. Atypical carcinoids had a tendency for nodal involvement (50% vs. 15%) and greater likelihood for disease recurrence, with a 5-year event-free survival of 50%. CONCLUSIONS: These data support the appropriateness of divergent management strategies for typical versus atypical bronchial carcinoids. We propose the following: (1) nonanatomic resection is acceptable only for peripheral typical carcinoids; (2) extended mediastinal dissection should be limited to central presentations, clinically aggressive, or atypical carcinoids; (3) atypical histology, especially with nodal involvement, is prognostic for recurrence and metastasis; (4) nonsurgical therapies only rarely achieve long-term freedom from disease.
