MRI-Guided radiation tailors treatment for anal cancer patients
NCT ID NCT06050707
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tests a new way to deliver radiation therapy for anal cancer using MRI guidance to adjust doses based on each patient's risk level. About 80 adults with anal squamous cell carcinoma will receive different radiation schedules depending on their tumor risk group. The study aims to see if this personalized approach can improve local tumor control and reduce side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Radiation therapy (MR-guided, risk-adapted dosing)
- What this could lead to
- If successful, this could offer a more personalized radiation approach for anal cancer, potentially improving tumor control and reducing side effects.
- What could go wrong
- This is a small, early-phase trial (80 participants) without a comparison group. The approach may not improve outcomes over standard treatment, and radiation side effects remain a risk.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients with pathologically proven diagnosis of anal SCC. This may include tumors of non-keratinizing histology such as basoloid or cloacogenic histology. Individuals with squamous cell carcinoma of the anal margin are eligible. * Clinical stage T1-4 N0-1 M0 (the Union for International Cancer Control (UICC) / the American Joint Committee on Cancer (AJCC) 8th Ed) * Patients must be eligible for definitive RT or CRT * Must be ≥ 18 years of age * Must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 Exclusion Criteria: * Previous chemotherapy, RT or curative-intent surgical treatment (i.e. APR) for anal cancer. * Any previous RT to the abdomino-pelvic region that would result in overlap of RT volume for the current study. * Individuals with a history of a different malignancy except if they have been disease-free for at least 2 years and are deemed by the investigator to be at low risk for recurrence. Individuals with the following cancers are eligible if diagnosed and treated within the past 5 years: cervical cancer in situ, and basal cell or squamous cell carcinoma of the skin.
