Enrollment

250 participants

Start Date

Jun 26, 2024

Plain Language Summary

Simplified for easier understanding

This trial tests whether a less aggressive treatment strategy — chemotherapy followed by local surgical removal of a rectal tumor, then monitoring — can avoid the need for full bowel removal surgery in patients with early-stage rectal cancer. **You may be eligible if...** - You have a confirmed early-stage rectal cancer (stage cT1–T3b, node-negative, no distant spread) - Your tumor is in the middle or lower part of the rectum and can be accessed for local removal (transanal excision) - You have not received any prior treatment for rectal cancer - You are medically fit for surgery and at least 18 years old - Your tumor is microsatellite stable (pMMR) — a specific tumor type - Your blood counts and organ function are adequate **You may NOT be eligible if...** - Your tumor is poorly differentiated, mucinous, or signet ring type - You have visible lymph node spread on MRI - You have had prior pelvic radiation - You have a tumor that has already been partially removed before joining the study without remaining visible disease - You have a known enzyme deficiency affecting fluorouracil metabolism (DPYD deficiency) Talk to your doctor to see if this trial is right for you.
