This trial is testing whether increasing the radiation dose in a short-course treatment — given before surgery — can help treat advanced rectal cancer more effectively. You would receive either standard, medium, or higher radiation doses over 5 days, followed by mFOLFOX6 chemotherapy. The goal is to see which dose level works best and is safest.
Current short-course radiation therapy has lower success rates at completely eliminating cancer cells compared to longer radiation courses, but takes less time. This trial is exploring whether higher radiation doses can improve these success rates while still keeping treatment quick and manageable.

You would be assigned to one of three groups receiving different radiation doses (all given over 5 consecutive days), followed by 4 rounds of chemotherapy spaced over several weeks. After the chemotherapy is complete, you would have surgery to remove the tumor. Throughout the trial, you'll have regular check-ups, blood tests, and imaging scans to monitor your health and how well the treatment is working.
