Plain English summary of protocol

Background and study aims
Almost half of cancer patients undergo radiotherapy as part of their treatment. Currently radiotherapy treatment planning involves using a CT scan to maximise radiation to the cancer whilst minimising radiation dose to healthy tissue. For many cancers the extent of the tumour is seen much better on Magnetic Resonance Imaging (MRI). This study will assess whether MRI can replace CT for radiotherapy planning for ano-rectal cancers.

Who can participate?
Adult patients (> 18 years) undergoing radiotherapy at Leeds Teaching Hospitals NHS Trust or the Northern Centre for Cancer Care (NHS) for anal and rectal cancers.

What does the study involve?
Patients who are already receiving radiotherapy as part of their treatment undergoing radiotherapy in Leeds Cancer Centre will be invited to participate in an imaging study where an additional MRI scan is obtained after informed consent have been taken. This study will have no impact on the participant’s treatment. The MRI scan will be used to compare the new method of treatment planning with the current method used routinely in patient care.

What are the possible benefits and risks of participating?
There are no direct benefits to taking part, however taking part will help patients in the future. There are some limited risks of taking part, associated with having an MRI scan. All risks will be clearly explained in the information sheets for the study.

Where is the study run from?
Leeds Teaching Hospitals NHS Trust (UK)

The researchers are collaborating with the Northern Centre for Cancer Care (NCCC) based at Freeman Hospital Newcastle-upon-Tyne, the Calvary Mater Newcastle Hospital (Australia), The Australian e-Health Research Centre (Royal Brisbane and Women's Hospital), a consortium of UK institutions supported by Cancer Research UK Centres Network Accelerator Award Grant (A21993) (ART-NET) and two medical companies: Spectronics Medical AB (Sweden) and Philips Healthcare (The Netherlands), to help develop this way of planning treatments. NCCC will participate in recruitment, the other collaborators will participate in the analysis of the anonymised data.

When is the study starting and how long is it expected to run for?
August 2018 to April 2021

Who is funding the study?
National Institute for Health Research (NIHR) (UK)

Study objectivesMR-only treatment planning is technically accurate, clinically implementable and has potential benefit for external beam radiotherapy treatments for ano-rectal cancer patients.
Ethics approval(s)Approved 01/08/2018, London - Surrey Research Ethics Commitee (Level 3, Block B, Whitefriars, Lewins Mead, Bristol, BS1 2NT, UK; +44 (0)207 1048058; nrescommittee.secoast-surrey@nhs.net), ref:19/LO/1298
Health condition(s) or problem(s) studiedColorectal Cancer
InterventionThis is technical process which will be carried out to assess whether MRI scans can be used to plan radiotherapy treatments, instead of the current standard of using CT scans, in patients with anal and rectal cancers who are due to undergo radiotherapy. This study will be investigating the clinical implementability of the whole treatment pathway for anal and rectal cancer patients including it's potential benefit.

A cohort of Leeds Cancer Centre and Northern Centre for Cancer Care patients due to undergo radiotherapy will have an additional, research only, MRI scan acquired. These patients will be identified by their clinical team or the research team as suitable when attending radiotherapy outpatient clinics. Suitable patients will be provided with a patient information sheet about the study and at the next visit to the radiotherapy clinic written informed consent will be obtained by the clinical or research team. The additional research MRI scan will be scheduled to coincide with radiotherapy appointments so that patients do not routinely need to come for an additional visit. All patient data will then be anonymised before analysis.

No IV contrast will be given with the MRI scans.

Anonymised patient MRI and CT scans from the Leeds Cancer Cencer and Northern Centre for Cancer Care patients will be shared under Information Governance authorisation to develop the technical process.

The researchers will not be collecting nor sharing any clinical information on patients.
