Brief Summary
Multinational observational study to describe diagnostic stage shift in patients with lung cancer using medical records. Increased lung cancer screening programs and increased utilization of other screening modalities such as large increase in community chest radiography referral rates in response to public awareness campaigns, as well as unintentional detections through cardiac CT(computed tomography) angiograms, or screening for coronary disease may help in detecting the disease at earlier curable stages. Availability and increased access to novel therapies increase the likelihood of an early-stage diagnosis aiming for improved survival.

Eligibility Criteria
This study does not involve direct recruitment of the patients. Aggregated data from the databases for each consecutive year starting from the baseline year until End of study. Patients with lung cancer meeting the following criteria will be included in the study.
You may qualify if:
- Adult female and male patients ≥18 years old.
- Confirmed diagnosis of lung cancer (either cytologically or histologically)
You may not qualify if:
- Patients presenting with recurrent or relapsed lung cancer.
- Patients with a concomitant cancer at the time of diagnosis of lung cancer, except for nonmetastatic nonmelanoma skin cancers, or in situ or benign neoplasms: a cancer will be considered concomitant if it occurs within 5 years of lung cancer diagnosis.
