Brain Radiotherapy Imaging for High-grade Glioma Using Hypoxia Targeting Through Oxygen-Enhanced Response (BRIGHTER)
High-grade gliomas (HGGs) are the most common type of brain cancer in adults. Life expectancy for patients with HGGs is low. Radiotherapy aims to cure the tumour, but this is hard because HGGs are resistant to treatment. Among the possible causes of resistance may be tumour cells with low-oxygen levels (hypoxia). The investigators know that hypoxia reduces tumour sensitivity to radiotherapy. Using a special imaging technique called oxygen-enhanced MRI (OE-MRI), the investigators can try to identify areas of the tumour with hypoxia. The investigators could then give those areas a higher dose of radiotherapy. This might improve tumour control. This study aims to see if OE-MRI can find low-oxygen areas in HGGs. The study will also assess whether higher radiotherapy doses can be simulated in these regions.
Project summary:
- Set up the OE-MRI process at Leeds Cancer Centre (LCC). OE-MRI settings will be tested on healthy volunteer participants to ensure the images are as good as possible.
- Participant Imaging. Patient participants with HGG will be recruited to take part. OE-MRI will be used to image participants during their treatment and track low-oxygen areas before treatment, halfway through treatment and 3 months after treatment has finished.
- Dose Escalation Assessment. Computer programs will be used to design radiotherapy treatments to test if higher radiation doses to the tumour's low-oxygen areas can better control the cancer. This will help understand if this targeted approach has potential benefits. This is modelling and will not alter routine clinical patient participant management.

실험적: OE-MRI in high-grade glioma
Participants with high-grade glioma undergo oxygen-enhanced MRI (OE-MRI) at multiple time points (pre-treatment, mid-radiotherapy, and post-treatment) to assess tumour hypoxia.
Oxygen is administered as a physiological stimulus during imaging.
Data are used to evaluate hypoxia and to perform radiotherapy dose escalation modelling.
No changes to standard clinical care are made.

Oxygen-enhanced magnetic resonance imaging (OE-MRI) is performed to assess tumour hypoxia.
Participants undergo MRI scanning while breathing oxygen administered as a physiological stimulus to generate contrast related to tissue oxygenation.
Imaging is conducted at multiple time points during standard treatment.
The procedure is used for assessment only and does not alter clinical management.

Quantification of tumour hypoxia using oxygen-enhanced MRI (OE-MRI)
기간: From enrolment to the 3 month post-radiotherapy follow-up imaging
|
This study aims to determine whether a special MRI- oxygen-enhanced magnetic resonance imaging (OE-MRI)- can effectively show regions of low oxygen in patients with aggressive brain tumours (high-grade glioma (HGG)), and whether this information can help doctors target radiotherapy more accurately and improve patient outcomes.
