    Concordance of Actionable Mutations in Liquid Biopsies and Matched Tumor Tissue of Brazilian Non-small Cell Lung Cancer (NSCLC) (LALCA 2023)
    The NGS panel could successfully detect actionable mutations in liquid biopsies with a high concordance rate and sensitivity. The detection of variants in cfDNA, but not in tDNA, suggests a greater representativeness of the mutational tumor spectrum in samples of liquid biopsies opening perspectives for employing this approach in the routing setting. The NGS assay for liquid biopsy may decrease tissue biopsies and turnaround time for report release, accelerating therapeutic strategies for NSCLC patients.
