EGFR (epidermal growth factor receptor) mutation is the most common type of gene mutation in lung cancer.21 EGFR mutations are present in the tumours of 30-40% of Asian and 10-20% of non-Asian patients with advanced NSCLC.22 Among all gene mutations, EGFR mutation has the highest prevalence rate in NSCLC patients, especially in Asian population.20 For people with advanced NSCLC, it is especially important to know whether their cancer cells have mutated EGFRs (mutation-positive), and understand available treatment options for EGFR-mutated lung cancer. New cancer treatments and medicines are always being developed so it is essential to know if one of them could be an option for treating the disease.
