Could some rectal cancer patients avoid chemo? new trial investigates
NCT ID NCT07688135
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This pilot study explores whether patients with margin-clear stage II or III rectal cancer who do not need a permanent colostomy can safely go straight to surgery instead of receiving chemotherapy first. Participants are randomly assigned to either 12 weeks of chemotherapy followed by surgery or surgery alone. The main goal is to see if enough patients agree to join the study, which would support a larger trial to determine if skipping pre-surgery chemotherapy is a safe and effective option.
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 lead to a larger trial that may change standard care, allowing some rectal cancer patients to avoid chemotherapy and its side effects.
- What could go wrong
- This is a small pilot study testing feasibility, not effectiveness. It may not prove that skipping chemotherapy is safe, and results may not apply to all patients.
