Quantitative Evaluation of the Impact of Relaxing Eligibility Criteria for Lung Cancer Based on Real-world Data

This is a real-world data analysis study (not a treatment trial) that examines whether loosening the standard eligibility criteria used in lung cancer clinical trials would allow more patients to participate and still produce valid results. Researchers look at a database of patients with advanced non-small cell lung cancer (NSCLC) to simulate what would happen if stricter inclusion rules were relaxed. **You may be eligible if...** - You are a patient in a real-world clinical database with a confirmed diagnosis of NSCLC (stage IIIB, IIIC, or IV) based on ICD-10 coding - You were diagnosed between January 2013 and December 2022 - You had at least two documented clinical visits after January 2013 **You may NOT be eligible if...** - Your NSCLC is stage I, II, or IIIA (only later stages are included) - Your records do not meet the minimum documentation requirements in the database Talk to your doctor to see if this trial is right for you.
