Stool and saliva tests could revolutionize colorectal cancer detection
NCT ID NCT07494201
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is collecting stool and saliva samples from 2,500 people with colorectal cancer to look for patterns in bacteria and genetic material (microRNA). The goal is to improve how doctors diagnose and predict the course of the disease. Participants provide samples at key points during their treatment and follow-up. This research does not test a new treatment but aims to find better ways to use existing tools.
