Cancer Screening: Colorectal (Cologuard vs Colonoscopy)
Sunday, February 22, 2026
|
🔬 Practice‑Changing Findings
Evidence from RCTs and meta‑analyses published in the last 12 months.
|
JAMA Internal Medicine (2025) - Randomized Clinical Trial
Key Findings
- FIT invitation produced higher initial screening completion vs direct colonoscopy invitation in average-risk adults.
- Colonoscopy showed higher advanced-neoplasia yield per completed test vs FIT, confirming a reach-versus-yield tradeoff.
📋 Practice Implication: Use shared decision-making to default reluctant or access-limited patients to FIT-first pathways, with rapid colonoscopy follow-up only for positive tests.
|
JAMA Network Open (2025) - Randomized Clinical Trial
Key Findings
- Proactive outreach at ages 45-49 increased completed CRC screening vs usual opportunistic care.
- Earlier invitation pathways improved first-screen uptake without a worse short-term safety profile vs standard timing.
📋 Practice Implication: Build standing workflows that trigger outreach at the 45th birthday so screening starts on time instead of waiting for annual visits.
|
Journal of Medical Screening (2025) - Randomized Controlled Trial
Key Findings
- Risk-adapted assignment increased detection efficiency vs uniform screening by directing colonoscopy to higher-risk groups.
- Cost-effectiveness improved vs one-size-fits-all strategies, with lower resource use per advanced lesion detected.
📋 Practice Implication: Adopt a risk-stratified intake step (family history, prior findings, comorbidity profile) before selecting FIT vs colonoscopy referral.
|
Radiology (2025) - Randomized Controlled Trial
Key Findings
- Single CT colonography and biennial FIT produced different advanced-adenoma and cancer detection patterns vs each other.
- The modality comparison showed meaningful participation differences, affecting population-level case finding vs relying on one test type.
📋 Practice Implication: When colonoscopy capacity or patient acceptance is limited, offer CT colonography as a structured alternative rather than deferring screening.
|
Annals of Internal Medicine (2025) - Randomized Controlled Trial
Key Findings
- Personalized risk messaging increased completed screening vs generic reminders in overdue adults.
- Behaviorally tailored communication reduced nonresponse vs standard outreach language in lower-adherence groups.
📋 Practice Implication: Replace generic portal reminders with personalized risk-framed scripts for patients who remain unscreened after first outreach.
|
JAMA Network Open (2025) - Randomized Clinical Trial
Key Findings
- Text-plus-video prompts increased stool-kit return rates vs text-only reminders.
- Drop-off between mailed kit receipt and sample completion decreased vs standard digital prompting.
📋 Practice Implication: Add a 30-60 second prep/return explainer video to automated texting campaigns to raise stool-test completion without extra clinic staff time.
|
Cancer Epidemiology (2025) - Randomized Controlled Trial
Key Findings
- Navigation support improved completed colonoscopy adherence vs usual scheduling processes.
- No-show and prep-failure rates were reduced vs standard care among patients with known completion barriers.
📋 Practice Implication: Reserve navigator referral for patients with prior missed colonoscopy or social barriers to convert referrals into completed procedures.
|
BMJ Open (2026) - Randomized Trial Safety Analysis
Key Findings
- Claims-linked follow-up identified measurable post-colonoscopy adverse events vs baseline utilization periods.
- Serious complications remained uncommon, but nonzero event rates support balanced counseling vs stool-based options.
📋 Practice Implication: In consent conversations, present absolute colonoscopy complication risk alongside benefits so patients can choose modality with realistic expectations.

New colorectal screening evidence favors strategy selection by participation, risk, and local capacity rather than one universal pathway. Randomized data continue to show a tradeoff: colonoscopy has higher per-test lesion yield, while FIT-based programs improve reach and population-level completion. For primary care, the most practice-changing updates are risk-adapted triage, age-45 operational outreach, and targeted interventions that measurably increase completed screening.
