A recent study has found that a cfDNA blood test has shown promising results in detecting colorectal cancer (CRC) early. The test had a sensitivity of 83% for CRC and 13% for advanced precancerous lesions. This noninvasive screening method could provide a more convenient alternative for patients who may decline current screening options.
The cfDNA blood test had 83% sensitivity for CRC, 90% specificity for advanced neoplasia, and 13% sensitivity for advanced precancerous lesions . Other noninvasive screening methods have sensitivity from 67% to 94% for CRC and 22% to 43% for advanced precancerous lesions .
"The results of the study are a promising step toward developing more convenient tools to detect colorectal cancer early while it is more easily treated," said senior author William Grady, MD, medical director of the Gastrointestinal Cancer Prevention Program at the Fred Hutchinson Cancer Center in Seattle, Washington.detection similar to stool tests used for early detection of cancer, could offer an alternative for patients who may otherwise decline current screening options," he sai
