The third-generation epidermal growth factor receptor (EGFR) inhibitor osimertinib is a promising therapeutic option for patients with advanced non-small-cell lung cancer (NSCLC) in second-line or first-line treatment because of its applications in selectively inhibiting EGFR T790M and EGFR-tyrosine kinase inhibitor sensitizing mutations.

KEY POINTS: CAPP-Seq is applicable to clinical samples for the identification of multiple somatic mutations.The T790M mutation of <i>EGFR</i> is associated with amplification of <i>MET</i>, <i>ERBB2</i>, or <i>EGFR</i> in NSCLC patients resistant to EGFR-TKIs.T790M-positive patients are molecularly heterogeneous, and genetic alterations coexisting with T790M may differ between patients treated with first-generation or second-generation EGFR-TKIs.

Osimertinib (AZD9291), a third-generation EGFR-tyrosine kinase inhibitor, can effectively prolong survival in non-small cell lung cancer (NSCLC) patients with EGFR mutations, particularly T790M mutations; however, acquired resistance to AZD9291 is inevitable, thus exploration of the targets of resistance is urgent.
