Immune cell shifts after colorectal surgery may predict who stays Cancer-Free
NCT ID NCT05015296
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This study tracks 7,000 colorectal cancer patients to see how their immune cells change during the period around surgery. Researchers want to know if these changes can predict survival, disease-free survival, and recurrence one year after surgery. The goal is to find simple, real-world indicators that could help guide treatment decisions without adding extra burden on patients or healthcare resources.
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 could help doctors predict which colorectal cancer patients are at higher risk of recurrence after surgery, potentially guiding personalized follow-up care.
- What could go wrong
- This is an observational study, not a treatment trial. It can show links but cannot prove that changing immune cells would improve outcomes. Results may not apply to all patients.
