A Real World Study of Participants With Non-Small Cell Lung Cancer (NSCLC) With Epidermal Growth Factor Receptor Mutation (EGFRm)

This study aims to better understand people who have advanced or metastatic non-small cell lung cancer (NSCLC) with an EGFR mutation. NSCLC is an advanced stage cancer of the lung, occurring due to mutations (changes) in the EGFR gene. The study will assess the participant demographic background (that is age, gender etc.), the treatments they receive, how well those treatments work, and their health outcomes.

Inclusion criteria: * Histologically or cytologically confirmed diagnosis of advanced or metastatic unresectable non-small cell lung cancerNSCLC (TNM stages IIIB-IV), and a documented EGFR mutation, between 01 July 2018 and 31 March 2022 * Diagnosed and treated at one of the participating study centers within the defined study period Exclusion criteria: * Participants who received any systemic cancer treatment outside the participating treatment centers * Participants diagnosed with any other malignancy within the 5 years prior to or during the study period, with the exception of cutaneous basal cell carcinoma or squamous cell carcinoma * Participants enrolled in clinical trials during the study period.
