Blood Test Detects 79% of Colorectal Cancers in Screening Study

A circulating tumor DNA (ctDNA) blood test demonstrated high sensitivity and specificity for colorectal cancer (CRC) detection in a large average-risk population, study finds.

Shield blood test offers hope for early colon cancer detection

Clinical Validation of a Blood Test Using Circulating Tumor DNA for

A recent groundbreaking study published in JAMA has evaluated the efficacy of a novel blood-based screening test designed for the early detection of colorectal cancer among average-risk populations. This development carries significant implications for both clinical practice and public health, considering the global burden of colorectal cancer as a leading cause of morbidity and mortality. The research underscores the potential of liquid biopsy …

Blood test could detect bowel cancer with 'acceptable accuracy'

A blood test which looks for bits of tumour DNA in the bloodstream has shown 'acceptable accuracy' in detecting bowel cancer, but the authors say the detection of advanced precancerous lesions remains a challenge. The test was able to correctly identify people with colorectal cancer 79.2% of the time (sensitivity), and it was able to correctly clear people who didn't have advanced colorectal tumours 91.5% of the time (specificity). However, the …
