Understanding Non-small Cell Lung Cancer (NSCLC) Patient Characteristics, Treatment Patterns and Outcomes Via Cross-sEctional Physicians suRvey-based Chart Audit

This is a retrospective, cross-sectional, non-interventional, multi-country survey-based chart audit study to evaluate real-world treatment patterns, patient clinical profiles, and clinical outcomes among a NSCLC patients receiving at least 1L SACT (Systemic anticancer therapy)

This is a retrospective, cross-sectional, non-interventional, multi-country survey-based chart audit study to evaluate real-world treatment patterns, patient clinical profiles, and clinical outcomes among aNSCLC patients receiving at least 1L SACT in Argentina, Brazil, Mexico, Australia, India, Taiwan, Malaysia, Hong Kong, and Turkey. All patient-level data, including patient demographic and clinical characteristics, treatment history, and clinical outcomes, will be collected retrospectively from existing patient medical records provided by participating physicians, without interference with treatment decisions.
