Trial Title: Prevalence and Incidence of Central Airway Obstruction in Advanced Lung Cancer

Study Design Characteristics:
- Allocation: None
- Intervention Model: None
- Observational Model: COHORT
- Primary Purpose: None
- Time Perspective: PROSPECTIVE
- Masking: None
- Phase: None
- Number of Arms: None

Eligibility Criteria:
Inclusion Criteria:~* Advanced lung cancer with indication for chemotherapy or chemotherapy + radiation therapy~Exclusion Criteria:~* Age \< 18 year~* Pregnancy~* Refusal to sign informed consent

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 85 Years
- Healthy Volunteers: f

Study Arms:
- Lung Cancer (Type: None): All patients with advanced lung cancer candidate for chemotherapy or chemotherapy + radiation therapy will be enrolled and followed-up for 1 year clinically and radiologically (Chest CT) to verify whether or not central airway obstruction is present at the time of diagnosis or occurs in the year following diagnosis (or in the life span from diagnosis and death in patients who die before 1 year of diagnosis). Furthermore, predictor variables possibly associated with central airway obstruction will be studied.

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