Abstract

Introduction: Primary tracheal cancer is uncommon, with poor survival. While surgical resection is the mainstay of therapy, the role of chemotherapy and radiation is poorly defined. We aimed to study the impact of treatment modalities on survival. Methods: Patients with primary tracheal cancer were identified from the National Cancer Database over 12 years, 2004–2015. Patient characteristics, tumor characteristics, treatment modalities, and survival were recorded. Factors associated with survival were assessed using Cox Regression. Results: Of the 1726 patients identified, 59% were male, 83% White race, 62% had a comorbidity index of zero, median age 64 years, median tumor size 2.7 cm, and median survival was 28.5 months (89 months for patients undergoing surgical resection). Cox Regression for all patients found adenoid cystic carcinoma (ACC) (p < 0.001), radiation (p < 0.001), and surgical resection (p < 0.001) to be associated with improved survival, while increasing age (p < 0.001) decreased survival. For patients receiving resection, ACC (p < 0.001) was associated with improved survival, while increasing age (p < 0.001) and positive margins (p = 0.002) were associated with worse survival. For R0 resections, ACC (p < 0.001) was associated with improved survival, while increasing age (p < 0.001) decreased survival, with chemotherapy and radiation having no impact. For R1/2 resections, ACC (p < 0.001) and radiation (p < 0.001) were associated with improved survival, while increasing age (p < 0.001) decreased survival, with chemotherapy having no impact on survival. Conclusions: Primary tracheal cancer is highly lethal, with surgical resection leading to the best chance of survival. For patients undergoing resection, radiation provided survival benefits for R1/2 but not R0, while chemotherapy did not impact survival regardless of margin status.
