CRC Research Update

American Cancer Society updates colorectal cancer screening to include blood-based testing
On May 27, 2026, the American Cancer Society updated its colorectal cancer screening guidance to include blood-based testing for some adults, expanding screening options beyond colonoscopy and stool tests. (The Lancet Oncology)
Study examines colorectal cancer risk following colonoscopy in older adults
A study by Sunil Samnani and Nauzer Forbes published in Gastroenterology on May 26, 2026, examines the risk of colorectal cancer following colonoscopy in older persons. (Gastroenterology)
Computer-aided detection devices tested in real-world colonoscopy settings
A cluster randomized study at Veterans Health Administration facilities examined whether computer-aided detection (CADe) devices improve adenoma detection rates during colonoscopy, addressing the gap between controlled trial results and real-world effectiveness. (Gastroenterology)
Mismatched symptom perceptions between patients and caregivers affect quality of life
A study of 271 colorectal cancer patient-caregiver pairs found significant disparities in how patients and caregivers perceive symptoms like sleep disturbance, which were associated with negative mood, relationship quality, and overall quality of life. (Journal of Patient-Reported Outcomes)

🔬 Under 50 Spotlight

Research relevant to early-onset and younger CRC patients

Meta-analysis quantifies adenoma rates in adults aged 40–49
A systematic review analyzed colonoscopy studies to estimate adenoma detection rates and advanced neoplasia prevalence in average-risk individuals aged 40–49, providing data to inform screening decisions for younger adults. (Gastrointestinal Endoscopy)

💙 Living with CRC

Survivorship, quality of life, and supportive care

Review identifies gaps in measuring patient experience during surveillance colonoscopy
A scoping review found no standard set of patient-reported outcomes or measures for individuals undergoing regular surveillance colonoscopy, despite guidelines recommending these assessments as quality indicators. (Quality of Life Research)

Research continues to expand screening access and improve the patient experience throughout the CRC journey.
