Plain English Summary

Background and study aims
Radiotherapy is a treatment involving the use of high-energy radiation. It is commonly used to treat advanced cancers of the head and neck, aiming to cure while preserving patients’ quality of life including their ability to speak and swallow. In order to reduce the potentially major side effects of treatment, it is essential that the highest doses of radiotherapy are targeted to the main bulk of the tumour. At present a computerized tomography (CT) scan is used by the cancer specialist to identify the tumour for planning the radiotherapy treatment. We know that other types of scan including magnetic resonance imaging (MRI) and positron emission tomography (PET) scans are better than CT scans at showing areas invaded by the cancer. However, radiotherapy cannot be directly planned on these types of scans. The aim of this study is to explore whether PET and MRI scans can be combined with CT scans to more accurately identify the tumour target. In addition, this study will explore whether PETCT and MRI scans may be used to adjust radiotherapy to how well a tumour is responding during a course of radiotherapy.

Who can participate?
Patients aged 18 or over with cancers of the head and neck undergoing a course of radiotherapy.

What does the study involve?
All patients within the study will undergo a PETCT and an MRI scan prior to starting treatment as part of the study. A subgroup of patients will undergo additional imaging at two timepoints during the course of their radiotherapy.

What are the possible benefits and risks of participating?
If the radiotherapy planning process can be improved in these ways, we hope future patients will benefit by more chance of cure with a reduction in the side effects of treatment. The participants’ standard treatment will not be affected by their participation in the study.

Where is the study run from?
St James's University Hospital (UK).

When is the study starting and how long is it expected to run for?
From July 2011 to May 2013.

Who is funding the study?
Leeds Teaching Hospitals Charitable Foundation (UK).

Study typeTreatment
Scientific titleAssessment of the use of co-registered 18-fluorodeoxyglucose-PET-CT and MRI for radiotherapy planning in locally advanced head and neck squamous cell carcinoma: a pilot study
Study hypothesisAn imaging study, with no change made to patients' treatment:
1. To explore whether PET and MRI scans can be combined with CT scans to more accurately identify the tumour target for radiotherapy planning
2. To explore whether PET-CT and MRI scans may be used to detect alterations in the tumour during a course of radiotherapy, to allow the future design of studies to look at adapting treatment according to tumour response
Ethics approval(s)National Research Ethics Service, Yorkshire and Humber (UK), 25/07/2011, reference: 11/YH/0212
ConditionRadiotherapy for head and neck cancer
Intervention1. Patients will have an MRI scan and an 18-fluorodeoxyglucose (18FDG)-PET-CT scan in a radiotherapy mask before the start of radiotherapy treatment
2. A subset of patients within the study will have repeat MRI and 18-FDG-PET-CT scans after 2 weeks and 4 weeks of radiotherapy treatment
Intervention typeProcedure/Surgery
Primary outcome measureAccuracy of imaging with a 18FDG-PET-CT and MRI for identification of head and neck
tumours for radiotherapy planning, assessed with intraobserver and interobserver comparison of delineation of tumour target by radiologists and radiation oncologists using PET, MRI and CT imaging; analysis will be done when recruitment is complete
Secondary outcome measures1. To determine whether CT scan routinely used to plan radiotherapy can be accurately merged with an MRI scan
2. To determine the feasibility of performing MRI and PET-CT imaging during a course of radiotherapy
3. To identify the most useful timepoints for imaging during radiotherapy to track tumour changes
4. To determine whether changes on MRI and PET-CT taken during radiotherapy could be used to improve the radiotherapy plan during treatment

These endpoints will be evaluated with quantitative contour comparison tools. Analysis will be done when recruitment is complete.
