Objective. Targeted next-generation sequencing (t-NGS) has revolutionized clinical diagnosis allowing multiplexed de­tection of genomic alterations. This study evaluated the profile of somatic mutations by t-NGS in Mexican patients with non-small cell lung cancer (NSCLC). Materials and methods. Genomic DNA was extracted from 90 lung adenocarcinomas and sequences were generated for a panel of 48 cancer ge­nes. Epidermal Growth Factor Receptor (EGFR) mutations were detected in parallel by quantitative PCR. Results. The mutational profile of NSCLC revealed alterations in 27 genes, where TP53 (47.8%) and EGFR (36.7%) exhibited the highest mutation rates. EGFR Q787 mutations were present in 14 cases (15.6%), 10 cases had exon 19 deletions (11.1%), seven cases had L858R (7.8%). The mutational frequency for genes like EGFR, MET, HNF1A, HER2 and GUSB was different compared to caucasian population. Conclusion. t-NGS improved NSCLC treatments efficacy due to its sensitivity and specificity. A distinct pattern of somatic mutations was found in Mexican population.
