A significant advancement in the detection of colorectal cancer has emerged from a recent clinical study, marking a significant step forward in expanding screening options for this potentially fatal disease.
Advancement in Colorectal Cancer Screening
Published in the renowned New England Journal of Medicine on Wednesday, the study revealed that a blood test designed to identify colorectal cancer performed admirably. It accurately identified colorectal cancer in 83% of individuals at average risk and devoid of symptoms, paving the way for more accessible and effective screening methods.
Promising Study Findings
Dr. William M. Grady, a gastroenterologist at Fred Hutchinson Cancer Center and the corresponding author of the study, expressed optimism about the results. He highlighted the test’s potential to detect colorectal cancer early, when it’s more treatable, offering an alternative to current screening options.
Comparison with Existing Screening Tests
Dr. Jon LaPook, CBS News chief medical correspondent and a gastroenterologist at NYU Langone Health, emphasized the significance of this blood test in providing an alternative to conventional screening methods like colonoscopy and stool testing. He underscored its attractiveness due to ease of administration and absence of discomfort associated with traditional tests.
Clinical Trial Insights
The study, conducted across multiple sites and involving nearly 8,000 participants aged 45 to 84, compared Guardant’s Shield blood test with colonoscopy, the current gold standard for colorectal cancer screening. Guardant Health, the test’s developer, led and funded the trial.
Importance of Screening
Despite colorectal cancer’s preventability through screening, a significant percentage of eligible individuals remain unscreened. Dr. Grady emphasized the importance of offering diverse screening options to encourage participation and early detection.
Rising Incidence of Colorectal Cancer
Colorectal cancer’s prevalence has surged in recent years, particularly among younger demographics, necessitating adjustments in screening guidelines to facilitate early detection and intervention.
Innovation in Screening Technologies
Both Guardant Health and Exact Sciences are pioneering advancements in colorectal cancer screening. Exact Sciences’ Cologuard Plus, an upgraded version of its stool-based test, demonstrates improved accuracy in detecting colorectal abnormalities.

Potential Market Impact
Despite recent pressure on Exact Sciences’ stock, the market for colorectal cancer screening remains substantial. Advances in screening technology, including blood-based tests like Shield, offer hope for increased screening uptake and improved patient outcomes.
Future Outlook
The potential FDA approval of Shield and Cologuard Plus could revolutionize colorectal cancer screening, providing patients with non-invasive, convenient, and effective options for early detection and intervention.
Summary
The emergence of innovative screening technologies underscores the ongoing efforts to combat colorectal cancer effectively. With promising advancements on the horizon, early detection and proactive intervention can become more accessible, potentially saving countless lives from this deadly disease.
