Detection of Colorectal Cancer Using a Blood-based, Six-Gene Biomarker Set

At the annual meeting of the American Association for Cancer Research (AACR) last month, researchers from GeneNews Corp. reported that the probability of colorectal cancer (CRC) in asymptomatic patients can be accurately stratified by RNA expression profiling of six genes in whole blood [1]. The company focuses on developing blood-based biomarker tests for the early detection of diseases and personalized health management.
