MR-Adaptive Radiation Therapy for Anal Cancer With EScalated-Treatment in a Risk-Optimized Approach
The proposed study is a phase II, single arm, open-label trial of MR-guided radiation therapy (RT) with risk stratified RT dose selection in patients with anal cancer. Based on previous data, a risk adaptive treatment approached is proposed in 4 groups: Low risk, standard risk, intermediate risk, and high risk. Human papillomavirus (HPV) DNA will be analyzed to identify novel biomarkers that predict chemoradiotherapy (CRT) response and toxicity.
Study details:
After being informed about the study and potential risks, all patients giving written informed consent will undergo a risk-stratified dose of treatment (radiation dose and chemotherapy number of cycles) based on predefined clinical and biological biomarkers for anal squamous cell carcinoma (SCC). Radiotherapy will be delivered on the MR-Linac for image-guided-radiation therapy (IGRT). Patients will be followed for up to 5 years after radiotherapy and be required to complete questionnaires and clinic visits.
Patients have the option to complete blood and tissue samples during the study.

What is the study measuring?
Primary outcome
| Primary Outcome Measure | Primary Outcome Description | Primary Outcome Time Frame |
|---|---|---|
| Change in locoregional failure (LRF) at Year 2 | Any local or regional failure from the date of registration to the date of any of the local or regional failure. | 2 years |
Secondary outcome
| Secondary Outcome Measure | Secondary Outcome Description | Secondary Outcome Time Frame |
|---|---|---|
| Presence of distant metastasis (DM) | Clear clinical/radiographic evidence of distant metastases in the lung, bone, brain, liver or other distant sites. | 5 years |
| Colostomy rate | The presence of a colostomy until colostomy removal. | 5 years |
| Disease free survival (DFS) | The time from the date of registration to the date of first record of any of the following events including local, regional, distant failure, or death due to any cause. | 5 years |
| Overall survival (OS) | The time from the date of registration to the date of death for any cause. | 5 years |
| Physician-reported toxicities | Using the National Cancer Institute (NCI) Common Terminology Criteria of Adverse Events (CTCAE) V.5. | 5 years |
| Patient Reported Outcomes | Using the Common Terminology Criteria of Adverse Events | 5 years |
| Quality of life (QOL) | Based on the completion of the European Organisation For Research And Treatment Of Cancer (EORTC-C30) questionnaire. The EORTC-C30 questionnaire is a 30 item instrument meant to assess some of the different aspects that define the quality of life of cancer patients. | 5 years |
| Quality of life (QOL) | Based on the completion of the European Organisation For Research And Treatment Of Cancer (EORTC-AN27) questionnaire. EORTC QLQ-ANL27 includes four quality of life domains: pain, bowel, sexual and stoma care problems and five single item (frequent urination, keeping clean, proximity to toilet, lower limb oedema, planning activities) | 5 years |
