Non-Small Cell Lung Cancer with Epidermal Growth Factor Receptor (EGFR) Common Mutations: New Strategies

Epidermal growth factor receptor (EGFR) mutations are described in 10–15% of Caucasian patients and in 50% of Asian patients with non-squamous non-small cell lung cancer (NSCLC). The introduction of tyrosine kinase inhibitors (TKIs) has revolutionized the therapeutic scenario and has changed the natural history of the disease. Despite the results obtained with osimertinib, a third-generation TKI, most patients experience disease progression. The search for new therapeutic strategies both to enhance first-line treatment and to ensure adequate second-line therapies represents an unmet medical need, towards which all efforts are being concentrated. In this review, we describe the main strategies identified to improve the prognosis of patients with EGFR-mutated NSCLC.
