Study Arms:
- Fluorescence/Narrow Band Bronchoscopy (Type: None): All patients in the group are examined by Fluorescence Bronchoscopy and Narrow Band Bronchoscopy to make a early detection of lung cancer.
- Routine Bronchoscopy (Type: None): All patients in this group are examined by routine bronchoscopy to make a early detection of lung cancer.

Based on this trial design, predict the completion outcome and termination type (if applicable).
