100,000-Person registry targets cancer screening gaps in underserved communities
NCT ID NCT07461493
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This observational study will enroll 100,000 adults aged 35 and older to build a registry and biorepository focused on cancer health disparities. Participants will provide health information, complete questionnaires, and donate blood, saliva, and stool samples over five years, with an additional five-year follow-up. The goal is to identify barriers to early cancer detection and support future research in communities at higher risk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this registry could help identify barriers to early cancer detection and guide future research to reduce health disparities.
- What could go wrong
- This is an observational study, not a treatment trial. It collects data and samples but does not test any intervention, so direct patient benefits are not guaranteed.

Who is studied
Participants ages 35 years and older from underserved communities, populations living near Superfund sites, designated cancer clusters, and areas affected by industrial contamination to be followed longitudinally over a decade to track cancer screenings and early detection of cancer. Sites will recruit and accrue patients from their clinic sites or at community outreach events community events, churches, health fairs, Federally Qualified Health Centers (FQHCs) and other venues.
