LUNG CANCER, SMALL CELL LUNG CANCER
In this nonrandomized clinical trial, 150 patients with suspected advanced lung cancer underwent ctDNA testing during initial diagnostic workup; 90 patients had tissue confirmation of advanced nonsquamous non–small cell lung cancer. Median time to treatment was 39 days vs 62 days for a reference cohort, with faster turnaround time for genotyping results.
