Key clinical point: Liquid biopsy is more effective and faster than tissue-based genotyping for identifying targetable mutations in advanced non–small cell lung cancner.
Major finding: The cell-free DNA test detected relevant mutations in 77 patients versus 60 patients with tissue testing – and at a median of 9 versus 15 days. Additionally, the cell-free DNA results were delivered significantly faster than the standard of care tissue results (median, 9 vs. 15 days).
Study details: A prospective multicenter study of 282 non–small cell lung cancer patients.
