Plain English summary of protocol
Background and study aims
Prostate cancer is the most common male cancer and 1-in-23 men will die from the disease. In recent years, prostate cancer deaths have overtaken those from breast cancer. The PROSTAGRAM trial is designed to look at new imaging techniques to screen for aggressive prostate cancer. The aim is to find an imaging technique, like mammograms for breast cancer, which can be used to screen for prostate cancer.
Who can participate?
Men aged between 50 and 69 years who are able to an MRI and ultrasound examination of the prostate
What does the study involve?
Men who agree to participate in the PROSTAGRAM study will attend a screening clinic and complete all tests during a single visit. This will include
1. A fast MRI. This uses magnetic pulses, which can take detailed pictures of the prostate. It does not use radiation.
2. Prostate ultrasound. This measures the stiffness of the prostate and is more cost effective than a MRI scanner
3. A PSA test which is the current standard test. This will be used so that we can compare the new tests against the existing tests
If any of these tests are positive, a prostate biopsy will be performed in a separate visit.
What are the possible benefits and risks of participating?
There is no guarantee that taking part in this study will benefit participants personally. The possible benefits include that participants may have prostate cancer picked up more quickly than it would have been if they were not taking part in the study. This could mean that the cancer is more treatable and the chance of surviving is better. However, participants will also be providing important information to help find out if these imaging tests work well.
The risks of taking part include that some men and their families may get very anxious and worried while they are waiting for their tests results. Also, we might find slow-growing or non-aggressive cancers that might not cause any symptoms or problems in your lifetime. Alternatively the tests can sometimes be positive in men who do not have aggressive prostate cancer. Finally, like all medicines, the medications used during the MRI scan can sometimes cause side effects. These include blurred vision, dry mouth, dizziness, increased heart rate, constipation and pain at the injection site.
Where is the study run from?
The study is run from Imperial College London, UK and the screening clinic will take place at Hammersmith Hospital, Imperial NHS Healthcare Trust, UK
When is the study starting and how long is it expected to run for?
September 2017 to December 2020
Who is funding the study? (who will be paying the costs that the trial will incur during its lifecycle?)
1. Wellcome Trust Senior Clinical Research Fellowship (UK)
2. The Urology Foundation (UK)
3. British Medical Association Foundation for Medical Research (UK)

| Scientific title | PROstate cancer Screening Trial using A Group of Radiological Approaches including MRI and ultrasound |
| Study acronym | PROSTAGRAM |
| Study objectives | 1. Biparametric MRI and/or prostate ultrasound have acceptable positive test rates and balance the detecting clinically significant and insignificant prostate cancers to justify evaluation as screening tests. 2. Biparametric MRI and/or prostate ultrasound are acceptable screening tests to men aged 50 to 69 years in the general population |
| Ethics approval(s) | National Research Ethics Service Committee London - Camberwell St Giles, 10/09/2018, ref: 18/LO/1338 |
| Health condition(s) or problem(s) studied | Prostate cancer |
| Intervention | Participants will be recruited from the community and attend a screening clinic (visit 1) where they will undergo the following screening tests: 1. Bi-parametric MRI, reported by a radiologist and CAD-AI system 2. Multiparametric ultrasound, including shearwave elastography A systematic +/- targeted biopsy will be performed if any tests are positive (visit 2), independent of the other tests. At visit 3, participants will be informed of their test results and follow standard of care treatment according to the outcomes of their test. There will be a 3 month follow-up period. |
| Intervention type | Other |
| Primary outcome measure | The proportion of men with a positive MRI defined by a Likert or PI-RADS (Prostate Imaging Reporting and Data System) score of 3 or greater on MRI report |
| Secondary outcome measures | 1. The proportion of men with screen-positive prostate ultrasound defined by a score of 3 or greater, assessed at visit 1 2. The proportion of participants within each MRI score or US score of 1, 2, 3, 4 or 5, assessed at visit 1 3. An evaluation of proportion of participants across each MRI and US score with no cancer, insignificant cancer and significant cancer with each test, assessed at visit 2 4. A comparison of the proportion of participants with a positive result for each screening test. A comparison of the proportion of men subsequently diagnosed with a clinically significant prostate cancer as defined by pre-specified histological definitions, assessed at visit 2 5. Comparison of different testing combinations in terms of biopsy rates, detection of insignificant cancer and significant cancers, assessed at visit 2 6. The correlation between imaging findings and digital rectal exam (DRE), assessed at visit 1 to compare the difference in cancer detection of US, MRI and DRE 7. The proportion of men who go onto definitive local or systemic treatment (in men who undergo radical prostatectomy the proportion who are upgraded at final histology). This will be assessed at visit 3 by the treatment decision on men diagnosed with prostate cancer. 8. The proportion of participants within a positive Episwitch biomarker panel and distribution of score, assessed at visit 1 9. Feasibility, measured based on a point-estimate of recruitment rates across different recruitment strategies, assessed at visit 1 10. Eligibility, assessed against pre-defined eligibility criteria with reasons for ineligibility recorded and compared across each screening test, assessed at visit 1 11. Retention and compliance rate, defined as the number of participants completing screening tests and any follow-up biopsy recommendation. The reasons for withdrawal will be documented with an optional survey offered to individuals. This will be assessed at visit 3 12. Individual costs for recruitment and screening, recorded in a resource utilisation log. These will be scaled up to provide an estimate of the cost for the subsequent study. This will be assessed at visit 3 13. Sensitivity analysis of the CAD/AI system, with histology and/or radiologist consensus as the reference standard, assessed at visit 2 14. Comparison of radiologist diagnostic performance for detection of clinically significant cancer with and without the CAD/AI, assessed at visit 1 15. Interobserver agreement with and without the use of CAD/AI as second reader, assessed at visit 1 16. Receiver operating characteristic (ROC) to compare the diagnostic performance of CAD/AI at different MAI scores, assessed at visit 1 17. Changes in Health-related quality of life (HRQOL), assessed using the 12‐item Short‐Form Health Survey (SF-12) at the baseline and follow-up at visit 1 18. Changes in worry and anxiety scores, assessed at visit 3 using: 18.1. Cancer Worry Scale (CWS) 18.2. State-Trait Anxiety Inventory (STAI) 19. Rates of biopsy related adverse events (infectious complications, urinary retention, haematuria requiring admission), assessed at visit 2 |
