Taken together, these results are consistent with the well-established notions that, regardless of ethnicity, the frequency of EGFR-mutations is higher among women, never/light smokers, and with NSCLC of ADC type, and that the exon 19-microdeletions and the p.L858R substitution in exon 21 are the most frequent EGFR-mutations in NSCLC [1]. This evidence concerns the gene EGFR and non-small cell lung carcinoma.
