Assessment
Primary outcomes 1. Changes in pulmonary function test results (peak expiratory flow) after vs. before airway stent removal
Key secondary outcomes 1. Changes in pulmonary function test results (FVC, FEV1) after airway stent removal
2. Changes in respiratory symptoms (frequency of coughing, amount of sputum, difficulty of expectoration, dyspnea) assessed by a visual analog scale after vs. before airway stent removal
3. Frequency of airway stent re-insertion
4. Incidence of adverse effects

Key inclusion criteria 1. Patients with an airway stent who require stent removal because of a response to tumor-specific therapy or stent-related respiratory symptoms
2. 20 years old or older
3. Informed consent
Key exclusion criteria 1. Patients expected to need stent re-insertion in the same setting as stent removal
2. Patients with multiple stents expected to undergo the removal of only some of them
3. Patients who cannot perform pulmonary function testing (e.g., patients with a tracheostomy or who are on mechanical ventilation)
4. Patients who cannot assess their respiratory symptoms using a visual analog scale
5. Patients who require stent removal due to stent migration
6. Patients who require bronchoscopic procedures other than stent removal (e.g., ablation of tumor or granulation tissue) in the same setting
