<i>MET</i> Amplification Status in Therapy-Naïve Adeno- and Squamous Cell Carcinomas of the Lung

Abstract

MET amplification is not a mutually exclusive genetic event in therapy-naïve non-small cell lung cancer. Our data suggest that it might be useful to determine MET amplification (i) before EGFR inhibitor treatment to identify possible primary resistance to anti-EGFR treatment, and (ii) to select cases that harbor KRAS mutations additionally to MET amplification and, thus, may not benefit from MET inhibition. Furthermore, our study provides comprehensive epidemiologic data for upcoming trials with various MET inhibitors.
