Detectability Of Uncommon Egfr Mutations In Nsclc Ngs Versus Pcr

Detectability Of Uncommon EGFR Mutations In NSCLC: NGS Versus PCR ...

Detectability Of Uncommon EGFR Mutations In NSCLC: NGS Versus PCR ... We describe the frequency of uncommon egfr mutations detected at our institution by next generation sequencing (ngs) and the ability of commonly used pcr assays to identify these alterations. By comparing the detection rate and type of targeted gene mutations in non small cell lung cancer (nsclc) between amplification refractory mutation system pcr (arms pcr) and next generation sequencing (ngs), the characteristics and application.

NGS Provides Improved Identification Of Uncommon EGFR Mutations Over ... Approximately 3% of nsclc patients have uncommon genetic alterations in the egfr gene. we report six new single mutations previously unidentified in nsclc patients. we report seven novel combinations of doublet mutations. Within the 18 month period, 45 patients were identified with uncommon egfr mutations via next generation sequencing (ngs). the patient samples were analyzed via pcr, which missed 30% of the uncommon egfr mutations that were detected by ngs. In patients with advanced nsclc detected by ngs, exon 19 deletion and exon 21 mutation were still the main types of egfr gene mutations, while mutation rates of exon 19 and 21 detected by ngs were significantly lower than which detected by arms pcr. Our findings suggest that the pcr tests evaluated would have missed more than 40% of patients with nsclc harboring egfr ex20ins mutations. ngs based genetic testing is preferable than standard pcr assays and can substantially improve the identification of the diverse profile of egfr ex20ins variants ….

We evaluated the diagnostic utility of ngs for egfr mutation detection in nsclc as a part of intra lab method validation in our center. This study analyzes the spectrum of egfr ex20ins variants in a large patient population from a global clinical trial and several real world cohorts and the ability of pcr kits to identify these alterations. Methods: in this study, we first evaluated the analytical performance of the ddpcr lung cfdna assay. we next analyzed the concordance of the results with tissue amplification refractory mutation system pcr (arms pcr) and plasma next generation sequencing (ngs) genotyping. Uncommon egfr mutations represent a rare subgroup of nsclc. data on the efficacy of different generations of tyrosine kinase inhibitors (tkis) in these rare mutations are scattered and limited to mostly retrospective small cohorts because these patients were usually excluded from clinical trials.
