Clinical Utility of Genomic Sequencing for Hereditary Cancer Syndromes: An Observational Cohort Study

PURPOSE: Genomic sequencing (GS) is increasingly used to improve diagnoses and inform targeted therapies. GS can also be used to identify the 10% of cancer patients with an underlying hereditary cancer syndrome (HCS), who can benefit from surveillance and preventive surgery that reduce morbidity/mortality. However, the evidence on clinical utility of GS for HCS is limited: we aimed to fill this gap by assessing yield of all cancer results and …
