REIMAGINE Trial Information

One in eight men will develop prostate cancer and the risk increases with age. Most will not die of it, but some do. Our ability to identify those men whose cancer will decrease either their quality or quantity of life remains poor. Nowhere else in modern medicine are the errors of over-diagnosis, over-treatment, missed-diagnoses and poor risk-stratification more extreme. These four errors - which impact directly on the 1 million men who undergo prostate biopsy each year in Europe alone - result in the application of treatments that have little or no benefit, leave men suffering with significant life-long harms and waste valuable healthcare resources.

The Re-IMAGINE Consortium has been created to undertake discovery that will correct these four key errors. The project will combine the underlying molecular changes in the cancer with state-of-the-art imaging. This will allow the prediction of prostate cancer status for the individual (low, medium or high risk) without recourse to biopsy. It will also allow prediction of which prostate cancers are likely to progress over time and which are not, this has largely eluded scientist so far. By doing so, men will be subject to fewer but better biopsies, improved risk stratification, appropriate treatment allocation, more benefit, less harm and more cost-effective care.

Re-IMAGINE achieve this by building on established partnerships between patients, advocacy organisations, clinicians, imaging experts, molecular biologists, methodologists and a broad range of industrial partners. The vision of Re-IMAGINE is built on recently published work showing that magnetic resonance imaging (MRI) of the prostate was 100% better at identifying men at risk compared to the standard prostate biopsy, and moreover missed no men with potentially fatal disease. MRI is now certain to become the future cornerstone of the risk-stratification process for men at risk of early prostate cancer. However, little is known about the use of MRI in combination with other markers in the body. The Re-IMAGINE programme consists of a number of work-strands (WS).

WS1 will create the first group (cohort) of men who receive a prostate cancer diagnosis by means of an MRI-based pathway. These men will, after appropriate consent, donate some tissue, blood and urine for marker analysis. They will be recruited from a number of major centres in London (about three to start of with), that have high quality MRI in place.

WS2 will test the performance of MRI in a population where cancer is less common - in men who have not had a PSA test. This will allow us to predict the exact proportion of men at risk within the community.

These work streams will generate a lot of data (clinical information, imaging data, as well as information from markers in blood, tissue, and urine). We will combine all this data for each patient using a secure database, in line with the General Data Protection Regulations (GDPR), analysis will include mathematical techniques.

Such a complex project will require high levels of project management and coordination. This will be achieved by building on existing and fruitful collaborations.  The Re-IMAGINE programme will have a strong PPI work strand.

Re-IMAGINE will transform the management of early prostate cancer from an era in which imprecision and uncertainty is the norm to one in which any patient can expect and benefit from a precise prediction of his own risk and better care as a result.
