For patients with EGFR mutation-positive NSCLC, first-line treatment with EGFR tyrosine kinase inhibitors (TKIs; specifically gefitinib [IRESSATM], erlotinib [TARCEVA®], and afatinib [GIOTRIF®]) has been associated with superior objective response rates and progression-free survival compared with chemotherapy [5, 16–18]. Here, EGFR is linked to non-small cell lung carcinoma.
