The aim of our work is to report the concordances between CTCs and ctDNA versus the primary FFPE tumour mutations using a NGS hotspot panel.
“Our results suggest on a next generation sequencing platform that the global genetic variant profile between DNA extracted from CTC had good agreement with FFPE primary tumour tissue, and the agreement between ctDNA and FFPE was much poorer!” said consultant thoracic surgeon Dr Eric Lim from Royal Brompton Hospital, London.
