Study information
Scientific title
Biological magnetic resonance imaging parameters in oropharyngeal squamous cell carcinoma (BIOPIC): a non-randomised study
Acronym
BIOPIC
Study hypothesis
This study will investigate new MRI scanning techniques in patients undergoing radiotherapy treatment for squamous cell oropharyngeal (head and neck) cancer. We are looking at whether there are any changes in the cancer when the patient breathes in additional oxygen or carbogen (oxygen with carbon dioxide). This is important as tumours with low oxygen tend to be less responsive to treatment with chemotherapy or radiotherapy. We are also looking at a new method of imaging glucose (sugar) as this is taken up by cancer cells more than normal cells. We currently use FDG-PET/CT scans to image glucose but this involves radiation, unlike MRI. Patients will be asked to have an extra MRI scan before, during and after treatment to look at changes seen with the new MRI techniques we are investigating. We will also be taking blood samples and accessing tissue samples, such as routine biopsies taken as part of clinical care. We will look at the changes that occur with treatment, both under the microscope and through genetic testing. We will then compare this information to the findings from the MRI scans and other scans done routinely as part of patient care. We are interested to see if the new MRI techniques might be useful to monitor cancer patients having treatment or to predict whether they are likely to respond to therapy. In future this may allow us to choose the right treatment for a patient or to modify a treatment to improve response. This study is funded by the Oxford Cancer Imaging Centre and the Oxfordshire Health Services Research Committee. Recruitment will take place at the Churchill Hospital, Oxford.

Intervention
This is an observational study to assess novel MRI imaging techniques T1 and T2* with supplemental oxygen and carbogen breathing and CEST. Baseline scans will be compared to imaging during and post treatment in patients undergoing radiotherapy for oropharyngeal squamous cell carcinoma. For glucoCEST, comparison to DCE-MRI and contemporaneous clinical FDG-PET will also be undertaken. An exploratory study will investigate immunohistochemical and genetic markers related to factors influencing response to radiotherapy and compare these to findings on imaging.
Patient will be recruited from a single centre (Oxford University Hospital Foundation Trust) and will receive standard treatment and follow-up as part of routine NHS care. 15 patients (group A) will undergo study MRI lasting no more than one hour at three time points (baseline, during and after radiotherapy). A subgroup of participants (group B) will have an additional MRI at baseline i.e. 4 study MRI scans in total. Every patient who agrees to participate in the study and is felt by the investigator to be suitable will be asked if they are willing to be part of group B until a total of 5 participants is reached. From seeking informed consent, patients will be followed until post-treatment imaging which takes place 10-12 weeks after completion of radiotherapy. The duration of patients participation will be approximately 4 months.
