Pan-cancer blood plasma cell-free RNA profiles reveal cancer type and patient-specific changes

PhD student Annelien Morlion presents her recent work on plasma cell-free RNA profiles in cancer type and patient-specific changes. Background: Circulating nucleic acids in blood plasma form an attractive resource to study human health and disease. While the presence of extracellular RNAs in plasma has been firmly established, their origin and clinical utility for management of cancer patients is less understood. Methods: In this study, we applied messenger RNA capture sequencing of blood plasma cell-free RNA from 266 cancer patients and cancer-free controls (discovery n=208, 25 cancer types; validation n=58, 3 types).
