Afatinib for the first-line treatment of patients with metastatic EGFR-positive NSCLC: a look at the data.

INTRODUCTION: Epidermal growth factor receptor (EGFR) mutations are detected in about 10-15% of Caucasian and 30-40% of Asian patients with advanced or metastatic non-small-cell lung cancer (NSCLC). In patients harbouring EGFR mutations, the treatment with different available EGFR tyrosine kinase inhibitors (TKIs) showed to be more effective and safe than platinum-based chemotherapy regimens. Areas covered: The current evidences about the role of afatinib for patients with EGFR-positive NSCLC are reviewed and discussed. We report a review based on a MEDLINE/PubMed, searched for randomized phase II or III trials evaluating afatinib in EGFR-positive NSCLC. Expert commentary: Afatinib is the third EGFR TKI approved for the treatment of NSCLC harbouring EGFR mutations, showing high efficacy in this setting of patients.
