The main aim of this study is to examine the percentage of people with lung cancer who carry a certain gene mutation (epidermal growth factor receptor exon 20 insertions - EGFR ex20ins) and their frequency in Chinese participants with Non-small cell lung cancer (NSCLC) after having been tested for the gene mutation. Data from the participant's electronic medical records at the hospital will be collected.
