EGFR T790M mutation represents around 50% acquired resistance to first generation EGFR TKIs of patients with NSCLC. Its earlier detection is consequently becoming crucial. We here propose an improvement of the PNA-mediated PCR followed by pyrosequencing to develop a highly sensitive method that could in the future be used to confirm conflicting results obtained with the method of reference, next generation sequencing. Moreover, an evaluation of the putative prognostic effect of the p.Gln787Gln polymorphism on EGFR-TKIs response will be performed.
