Description of intervention(s) / exposure
Eligible study participants will be treated with stereotactic ablative radiotherapy (SBRT) at the department of Radiation Oncology. SBRT is the standard of care for patients with limited areas of progressive disease. The process of the radiotherapy includes simulation, radiation planning and delivery.
During the simulation, all patients will undergo CT and MR of the region of interest encompassing the disease to be treated. Patient’s positioning and immobilisation device will also be determined.
Based on planning CT and MRI, the gross tumour volume, the number of the oligo-progressive sites that can be treated and targetable with SBRT will be determined by one of the investigators (consultant radiation oncologists). Dose and fractions will be prescribed according to the tumour site, total radiation dose may span from 16 to 60 grays, the number of fractions can be between 1 and 8, and the dose for each treatment session (fraction) will be between 6 to 34 grays.
SBRT will be delivered by 2 qualified and experienced radiotherapists. One fraction will be delivered each day, the total dose will be given on consecutive weekdays or every 2nd day.

The PET scan will be done at Austin PET centre, the department is well equipped and is able to generate 89Zr labelled antibodies. The radiotracer will be administered via IV injection, and the scan will take 60 to 90 minutes.

Outcomes
Primary outcome [1] 330675 0
The changes in CD8+ T cells biodistribution in the body and tumour after SBRT.

To detect whole body and tumour immune cells (CD8 T cell) distribution in patients with head and neck cancer, PET imaging study using an anti-CD8 radiolabelled minibody 89Zr-Df-IAB22M2C will be performed at baseline and 2-week post radiotherapy. Biodistribution changes post radiotherapy from baseline will be analysed.
Timepoint [1] 330675 0
2 weeks after SBRT
Secondary outcome [1] 407165 0
To assess the utility of anti-CD8+ PET imaging and to correlate imaging finds with circulating T cell profile

At the same time of PET imaging, the blood samples will be collected to assess the circulating immune cell (CD8 T cell) level. Correlation of whole body CD8 distribution by PET imaging with circulating CD8 T cell levels may confirm the effectiveness of anti-CD8+ PET imaging.
Timepoint [1] 407165 0
2 weeks after SBRT
