Summary

The study will be a phase 2, open-label study in patients with solid tumours to explore the relationship between short-chain fatty acid uptake using \[18F\]FPIA PET/CT and tumour proliferation

Detailed description

Cancers have increased energy demands to allow for their rapid growth compared to healthy cells. Glucose is the main source of energy for many cells in the body, and clinicians routinely use a scan which looks at glucose metabolism to assess if cancer treatment is working. However, some cancer cells can create energy to survive and grow in a different way, using fatty acids. In this study, the investigators are using a PET/CT scan to look at a variety of cancer types to see which cancers use fatty acids for energy and if this can be measured. The PET/CT scan will be carried out twice on 2 separate visits so that the investigators can check that both scans give the same result. The investigators will also carry out special tests on the tumour tissue taken during routine cancer surgery. These tests will look for specific substances in the cancer cells that are related to cancer biology and growth. The investigators will then compare the results from the surgical tissue to the results of the scan to see if there is a relationship between them. The study will look at 21 patients with solid tumours conducted in 4 NCITA accredited centres, which have different strengths in recruiting specific patient/tumour-type cohorts. Each patient will have two scan visits (between 2-15 days apart) prior to any new treatment starting to check that the scan measurements are repeatable.
