New Blood Test Could Reshape Early CRC Screening

A simple blood test that looks for a combination of specific RNA snippets may become a novel way to screen for early-onset colorectal cancer, suggests a new study published online in Gastroenterology. Researchers identified four microRNAs that together comprise a signature biomarker that can be used to detect and diagnose the presence of colorectal cancer from a liquid biopsy in a younger population.
@dev-narayan MicroRNAs, or miRNAs, are small RNA molecules that do not encode proteins but are used instead to regulate gene expression. The study authors developed and validated a panel that detects four miRNAs occurring at higher levels in plasma samples from patients with early-onset colorectal cancer, with high sensitivity and specificity.
