abstract

  • 11016 Background: NGS techniques enable the identification of actionable mutations in clinical tumor samples. The objective of this study is to assess feasibility and explore the impact of real-time targeted NGS on therapeutic decision-making. Methods: Patients (pts) with advanced solid tumors underwent a biopsy of a metastatic lesion. The first phase was performed with Sequenom MassARRAY somatic genotyping and Pacific Biosciences RS-targeted NGS. The second phase broadened genomic coverage in both Sequenom and Illumina MiSeq. All pts had a molecular profiling (mp) report issued after identified actionable mutations were verified by Sanger sequencing in a CLIA-lab and reviewed by an expert panel. “Actionability” was defined as having prognostic, predictive or diagnostic implications on patient management. Details of clinical outcomes and subsequent matched therapy, if applicable, were captured. Referring physicians were surveyed on the impact of mutation results on their treatment recommendations. Results: These are summarized in the Table. Conclusions: Broader mp platforms resulted in more identified actionable mutations which required a longer time for verification prior to reporting, but may yield a greater impact on clinical decision-making. However, the matching of pts to drugs based on their molecular profiles depends highly on drug access. For mp to be clinically relevant, it must be coupled with access to approved drugs or to investigational agents on clinical trials. Clinical trial information: NCT01345513. [Table: see text]
