#4505 NET-IMPRESS: A novel methylation-based assay to diagnose and monitor NET patients using liquid biopsies

Introduction: Previously, we showed that analysing copy number alterations (CNAs) in cell-free DNA (cfDNA) of NET patients using shallow whole genome sequencing (sWGS) is a potential biomarker for diagnosis and follow-up (PMID: 34759042). We now present NET-IMPRESS, an easy, cost-effective methylation-based assay for detecting circulating tumour DNA (ctDNA) in NET samples.
