Blood-Based Genetic Testing for Colorectal Cancer Screening

July 28, 2016

Screening for colorectal cancer (CRC) allows for the early detection and removal of cancers or precancerous polyps, resulting in improved overall survival. Despite current screening recommendations and screening tools, compliance is low. In an attempt to increase compliance, several blood-based genetic tests have been developed and are offered commercially. However, before this testing is used in clinical practice, it is important to establish whether it results in changes to clinical management and improves patient outcome. This report examines the clinical utility of blood-based screening tests for CRC.
