PERfusion CT in the FOXFIRE Trial to Study Blood Flow to Liver Metastases

Early Phase 1

• Conditions: Metastatic Colorectal Cancer

• Registration Number: NCT01410760
• Lead Sponsor: University of Oxford

Brief Summary

The PERFORM study is a pilot study investigating the feasibility and usefulness of performing a novel CT (Computed Tomography)scanning technique called Perfusion CT(CTP) as an addition to normal CT scanning in patients recruited to the FOXFIRE trial. All patients recruited to FOXFIRE at the Oxford Radcliffe Hospitals and University Hospitals of Leicester will be invited to take part. FOXFIRE is a national randomised controlled trial in which patients with unresectable liver tumours secondary to colorectal cancer will receive treatment with standard chemotherapy alone, or with chemotherapy in combination with an internal radiotherapy treatment which delivers radioactive particles(SIR-spheres) to the liver via its own blood supply (radioembolisation). In the FOXFIRE study a normal CT scan would usually be performed prior to the start of treatment and also three months after the commencement of treatment to assess the cancer's response to treatment, particularly whether the tumour has changed in size as a result of treatment. Perfusion CT gives the normal information on changes in tumour size but also assesses whether the blood flow to the cancer has changed, which may allow earlier identification of treatment success compared to normal CT scans. All patients consenting to participate in the PERFORM study will undergo four perfusion CT scans: one before the treatment starts, and one at the start of each of the second, third and fifth cycles of chemotherapy. The aim is to determine the feasibility of measuring tumour perfusion for data analysis using perfusion CT and to establish if the tumour perfusion pattern at baseline or shortly after the start of therapy can predict response to radioembolisation or chemotherapy. This research is funded by the National Institute for Health Research Biomedical Research Centre in Oxford and Oxfordshire Health Services Research Committee.
