简要总结
This is a prospective pilot study to investigate the potential clinical value of oxygen-enhanced magnetic resonance (OE-MRI) biomarkers in head and neck radiotherapy.
详细描述
This is a prospective pilot study funded by the NIHR. Healthy participants and patients will be recruited in The Christie NHS Foundation Trust and will be asked to undergo oxygen-enhanced magnetic resonance imaging (OE-MRI) and dynamic contrast-enhanced MRI (DCE-MRI). This study builds on the work recently been completed in lung cancer. Clinical data will be collected from patients notes.
Tumour hypoxia is common in solid tumours and associated with poor response to radiotherapy, poor loco-regional control and survival outcomes in head and neck cancer. There is a need to develop non-invasive tests that can measure tumour hypoxia to improve radiotherapy for these patients. The study will involve 3 components:
- Reproducibility and feasibility: The reproducibility of OE-MRI in head and neck cancer is unknown. Ten healthy participants will be asked to undergo two baseline OE-MRI scans with either nasal cannula or facial mask to breathe air and oxygen throughout. The order of which non-invasive breathing method will be used first will be randomized.
Following this initial pilot OE-MRI will be tested in 30 patients with solid head and neck tumours. To assess reproducibility in patients 2 OE-MRI will be performed at baseline. 2. Effect of radiotherapy on tumour and normal tissue: OE-MRI and DCE-MRI signals will be measured at baseline before standard radiotherapy treatment begins and at the end of week 2 week and week 4 following the start of radiotherapy. Comparison of hypoxia measurements will be taken. 3. Biological validation: All 30 patients will undergo a diagnostic biopsy as standard of care at their local hospital. Tissue samples will be requested and multi-gene hypoxia signatures will be tested. OE-MRI signals will be compared with tissue sample from the same patient and the presence of changes in tumour known to be associated with hypoxia will be analysed.

入选标准
- •Aged 18 or over
- •Able to receive and understand verbal and written information regarding the study and given written informed consent
- •Eastern Cooperative Oncology Group (ECOG) performance status 0-2
- •Adequate renal function: Calculated creatinine clearance (Cockcroft-Gault) ≥30mL/min
- •Be able to lie comfortably on back for up to 1 hour
- •Be able to tolerate a thermoplastic shell
- •Female patients must meet one of the following criteria:
- •i. Postmenopausal for a minimum of one year ii. Surgically sterile iii. Not pregnant, confirmed by B-HCG blood test. iv. Not breastfeeding
- •Cohort A (healthy participants): Up to 10 will be recruited to validate the use of nasal cannula
- •Cohort B (patients): Any patient with HNSCC who is due to start definitive radiotherapy +/- chemotherapy. Up to 30 will be recruited. Each patient prior to recruitment will undergo a diagnostic biopsy at their local hospital as standard of care. The formalin fixed paraffin embedded (FFPE) tumour biopsy sample blocks will be requested from each site and stored in the Manchester Cancer Research Centre (MRCR) and tested for a multi-gene signature.
排除标准
