Spots Global Cancer Trial Database for Whole Body Magnetic Resonance Imaging Study

Study Description

Brief Summary: In prostate cancer bone is the most common site for cancer spread, causing pain, fractures, nerve compression and death. New therapies are available for treating bone disease from cancer and this means that by maintaining patients on drugs that are effective and switching patients to other drugs when current treatment becomes ineffective, patients can be maintained 'better for longer'. However, to do this, it is necessary to accurately tell whether a given treatment is working or not. In this study, the investigators will perform whole body MRI scans, which include a special scan called diffusion-weighted MRI (DWI MRI) that can provide more information about the participants extent of disease. The investigators aim to show that this test is better than the standard tests of CT and bone scan currently used in the NHS to monitor bone disease. The information from this study will be used to test a special software so that the test may more widely benefit patients across the NHS in the future.

Detailed Description: In patients with prostate cancer the current methods to assess treatment response of bone disease such as computer tomography (CT) and bone scan (BS)are unreliable, insensitive to bone disease and have limited criteria to assess disease response confined to bones. Blood tests are inaccurate although some newer tests (e.g. circulating tumour cells tests) show promise but are still under investigation and nuclear medicine investigations such as PET/CT imaging have higher sensitivity, meaning they can detect more sites of disease who are indeed disease than CT or BS but they are more costly and less widely available compared with MRI within the NHS. For this study the Whole body MRI (WB-MRI) includes a measurement called diffusion-weighted imaging (DWI) which is relatively new and has a high sensitivity for bone metastases. This technique can be used to measure total bone disease volume (TDV) and the disease apparent diffusion coefficient (ADC) which reflects the tumour tissue cell density. Previous studies have shown good reproducibility of both these measurements and a significant increase in the mean tumour ADC is observed in patients who are responding to effective treatment. However WB-MRI application across the NHS is ad-hoc, CT and BS techniques are entrenched within clinical practice despite their known limitations. Another factor that limits wider adoption of WB-MRI is the lack of sophisticated analysis software to enable disease across the body to be quickly evaluated. This multi-centre imaging study will provide the opportunity to evaluate the performance of WB-MRI with a novel software diagnostics for evaluating the treatment response of advanced prostate cancer patients. This prototype can used to evaluate WB-MRI data from different scanners and address a current major unmet need for the treatment and follow-up of patients with bone disease from cancers, so that the test may more widely benefit patients across the NHS in the future.
