Can a chemo boost outsmart lingering colon cancer cells?

NCT ID NCT05534087

First seen Jul 31, 2026 · Last updated Aug 11, 2026 · Updated 2 times

Summary

This trial is testing whether giving a stronger chemotherapy regimen (mFOLFIRINOX) early can improve outcomes for people with stage II-III colon cancer who still have signs of cancer DNA in their blood during standard adjuvant chemo. Participants are randomly assigned to either receive the intensified treatment or continue with standard chemo. The goal is to see if the intensified approach can reduce the chance of cancer returning or spreading.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Intensified chemotherapy with modified FOLFIRINOX regimen
What this could lead to
If successful, this approach could offer a more effective treatment strategy for colon cancer patients at high risk of recurrence, potentially improving their chances of staying cancer-free.
What could go wrong
The intensified regimen may cause more side effects, and it's uncertain whether it will improve survival compared to standard treatment. The trial is still ongoing, and results are not yet available.
