Ngs Provides Improved Identification Of Uncommon Egfr Mutations Over Pcr In Nsclc

By hairstyler On Apr 25, 2025 Last updated

Detecting Egfr Mutations In Patients With Non Small Cell Lung Cancer In this research, we have analyzed the clinical pathological characteristics and egfr gene mutations of 4467 patients with nsclc in southwest of china, and then analyzed the correlation between the clinical pathological characteristics and egfr gene mutations which could help to provide data support for targeted drug use. Detection of sensitive mutations to egfr tkis has stimulated the interest in studying multiple oncogenic drivers. previous results suggested that somatic mutations in egfr, kras, braf, nras, pik3ca, her 2 and tp53 have been associated with efficacy of egfr tkis, metastasis or overall survival (3–6).

Egfr Mutations In Patients With Non Small Cell Lung Cancer From Among egfr pcr negative cases, ngs detected uncommon egfr mutations (l861r l833f, a750fs, g779f) in 3 cases. cohen’s kappa coefficient for egfr mutation detection between pcr and ngs was 0.96 [95%ci 0.917 to 1.005]. ngs and gene fusion panel pcr recognized an additional 37 155 cases (23.9%) harboring other oncogenic driver alterations (table). 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. nsclc samples that underwent ngs at the clinical genomic lab at the royal marsden hospital were assessed to identify cases with egfr mutations in exons 18 21. In this study, we verified the technical efficiency of a novel dpcr platform (qiacuity™ digital pcr system, qiagen; hilden, germany) by applying it to a retrospective series of archived nsclc liquid biopsy specimens (n = 25 egfr kras wild type, n = 25 egfr kras mutated cases) previously tested with ngs. comparative results between the two. Aims: the emergence of sophisticated next generation sequencing (ngs) based technologies in routine molecular diagnostics has paved the way for robust and accurate detection of variants which may otherwise be missed on single gene testing. this study aims at highlighting the same premise in egfr mutated non small cell lung carcinoma (nsclc).

This was a systematic review on the efficacy of tkis in patients harboring uncommon egfr mutations, defined as mutations other than exon 20 insertions mutations or t790m. response rates (rrs) for different generations of tkis were determined for individual uncommon mutations, compound mutations, and according to classical like and p loop alpha. In this research, we have analyzed the clinical pathological characteristics and egfr gene mutations of 4467 patients with nsclc in southwest of china, and then analyzed the correlation between the clinical pathological characteristics and egfr gene mutations which could help to provide data support for targeted drug use. Background the advent of novel therapeutic agents has advanced biomarker characterization in non small cell lung cancer (nsclc), driving increased adoption of next generation sequencing (ngs) technologies for molecular testing. however, comprehensive data addressing the clinical utility of different ngs platforms for nsclc remains limited. methods this retrospective study analyzed real world. In our study, the targeted ngs assay showed a number of superior features over the single gene qpcr in detection and identification of druggable egfr variants (exact identification of egfr variants, calculation of allelic frequency, high analytical sensitivity), which might enhance the basic diagnostic report.
