Comparing two radiation treatment approaches for stage II rectal cancer
Official title: A Phase III Study Testing Two Dose Escalation Strategies to Increase the Population of Complete Responders After Radiation Therapy in the Context of Organ Preservation for Patients With Rectal Cancer
Run by Sir Mortimer B. Davis - Jewish General Hospital · NCT03051464 · Data updated 2026-11-12
This study is testing two different ways of giving radiation treatment to see which one helps older patients with stage II rectal cancer better avoid surgery and keep their rectum.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults over 18 with clinically staged T2-3 N0 rectal cancer who meet specific tumor size and location criteria.
✕Probably not a fit
Patients with advanced disease stages, distant metastasis, or those who have previously undergone pelvic radiation will not benefit from this study.

What this trial studies
This study is a randomized clinical trial involving 131 patients with clinical T2-3 N0 rectal cancer. Participants will be assigned to one of two treatment arms: one receiving standard chemoradiation followed by an external beam radiation boost, and the other receiving the same chemoradiation followed by a brachytherapy boost. The aim is to optimize non-surgical treatment options and achieve complete clinical response, particularly important for older patients with multiple health issues. The study will evaluate the effectiveness of these two radiation dose escalation strategies in preserving the rectum.
Why it matters
Potential benefit: If successful, this study could provide a non-surgical treatment option that preserves the rectum for patients with stage II rectal cancer.
How similar studies have gone: Other studies have shown promise in optimizing non-surgical approaches for rectal cancer, making this a relevant and potentially impactful investigation.
