Objective: To analyze the clinical features in adults with tracheal neoplasm and to evaluate the efficacy of interventional bronchoscopic treatment. Methods: We retrospectively analyzed the clinical features of 43 adults undergoing therapeutic bronchoscopy for tracheal neoplasm diagnosed in Changhai Hospital affiliated to the Second Military Medical University from January 2004 to July 2014.The degree of stenosis, the grade of dyspnea, and Karnofsky performance status scale were evaluated before and after the last procedure. All cases were followed up for 2 years. Results: The 43 cases took (4.6±3.9) months on average to be diagnosed since initial symptom. The initial misdiagnosis rate was 41.9%(18/43), and 11 cases were mistaken for asthma (11/43). Malignant tumors were more common than benign tumors for tracheal neoplasm in adults. Squamous cell carcinoma and adenoid cystic carcinoma were the top 2 histological types. Central airway obstruction was completely or partially alleviated with significant relief of dyspnea after the procedures, and all 6 cases of tracheal benign tumors got complete alleviation (the overall response rate was 100%). The grade of dyspnea was 3.2±0.7 before and 1.5±0.8 after the procedures(t=6.63, P<0.05). The value of KPS was 63±12 before and 83±11 after the procedures(t=5.78, P<0.05). The 2-year survival rate of 6 cases of tracheal benign tumors was 100.0%, and 1 case of papillomatosis had a relapse. The 1-year survival rate and 2-year survival rate of 37 cases of tracheal malignant tumors were 59.5% and 43.2% respectively with a median survival of 13.6 months. Conclusion: Therapeutic bronchoscopic interventions provide significantly alleviation of central airway obstruction and result in improvement in shortness of breath and quality of life for tracheal neoplasm.
