Abstract Disclosures

Abstract:

Background: Lung cancer is the cause of 1 in 5 cancer deaths worldwide and is frequently driven by somatic mutations acquired in key genes. Targeted Next-Generation Sequencing (NGS) is a valuable tool for identifying mutations in these genes and has improved our understanding of disease progression. However, these mutations are not limited to just single nucleotide variants (SNV) or Insertion/Deletions (InDel) but also include complex chromosomal changes such as copy number variants (CNV) and fusions. Methods: The GeneRead QIAact Lung All-in-One Assay has been designed to include 549 DNA variants and 5 CNVs, plus 79 RNA fusions (including MET exon 14 skipping) known to be important in lung cancer. Samples used in this study were formalin-fixed paraffin embedded (FFPE) reference standards, CNV positive cell lines, and FFPE lung cancer samples. Following target enrichment of DNA and RNA using the GeneRead QIAact Lung All-in-One Assay the libraries were sequenced on the GeneReader and mutations assessed using QIAGEN Clinical Insight (QCI) Analyze. Results: To confirm both DNA and RNA mutation detection, Horizon® Discovery Reference Standards containing DNA (SNVs and InDels) and RNA (fusions) mutations, typical of FFPE samples (Quantitative Multiplex and ALK-RET-ROS1 Fusion RNA Reference Standard), and well-characterized cell lines were used. All expected DNA (5% allele frequency threshold appropriate for FFPE DNA) and RNA mutations were repeatedly identified both within and between runs. Testing of clinical samples consistently detected the expected RNA fusions (EML4-ALK) and DNA mutations (EGFR and KRAS mutations) previously identified by FISH or quantitative PCR (QIAGEN therascreen®), respectively. Conclusions: These data showcase the performance reliability of the QIAact All-in-One Assay on the GeneReader NGS System. This is the first study of its kind to systematically demonstrate the ability of a single assay to test for a wide range of mutations including complex chromosomal rearrangements. This allows a laboratory to accurately detect actionable lung cancer mutations with a single NGS assay in one seamless workflow, greatly improving efficiency and effectiveness.
