PROMIS - Prostate MRI Imaging Study: Evaluation of Multi-Parametric Magnetic Imaging in the Diagnosis and Characterisation of Prostate Cancer
Can MRI improve the diagnosis of prostate cancer?
  • What is this study about?

    There are over 40,000 new cases of prostate cancer each year in the UK. The dramatic increase in diagnoses over the last 20 years is mainly due to serum Prostate Specific Antigen (PSA) testing in healthy men. At present, men with a raised PSA level are usually advised to have a transrectal ultrasound (TRUS) guided biopsy. Most men undergoing TRUS biopsy will not have prostate cancer and sometimes these biopsies can miss cancers or underestimate how serious they are. However, at the present moment, TRUS biopsy is the standard of care for men with a raised PSA who are advised, and agree to have, further investigations.

    PROMIS will test the value of Multi Parametric Magnetic Resonance Imaging (MP-MRI) for men who have been recommended to have a prostate biopsy. It will investigate whether MP-MRI can be used (i) to advise whether or not men might safely avoid biopsy and (ii) to help us do better biopsies for men who have them.

    The study involves all men attending for 4 hospital visits over approximately 4 months (see also the trial schema at the bottom of the page):

    1. Registration - to check eligibility and obtain consent
    2. MRI scan
    3. Combined Biopsy Procedure (CBP)
    4. Follow up - patients find out and discuss the results of the MRI scan and biopsies with a clinician.

    Men who participate in PROMIS will have biopsies. This is called the Combined Biopsy Procedure (CBP). The CBP will be performed under general or spinal anaesthetic and includes both a template prostate mapping (TPM) biopsy and a TRUS biopsy. TPM is a more accurate biopsy which is not usually offered to patients at present. It involves taking biopsies from the whole prostate. TPM is included so that we can compare the results of the MRI scans with a more accurate biopsy (TPM) and the current standard (TRUS). The MRI scans, TPM and TRUS biopsies will be assessed independently.

    Overall, we hope this will improve the future accuracy of prostate cancer diagnoses and the subsequent management and treatment of patients.
  • Who is included?

    Men currently advised to have a prostate biopsy
  • When is it taking place?

    PROMIS began recruitment in March 2012 and will continue until 2015.
  • Where is it taking place?

    The pilot phase was run in two centres and successfully completed with no safety concerns and a recommendation to continue to the main phase.

    The following centres are open:

    - University College London Hospital NHS Foundation Trust (original pilot centre)
    - North Hampshire Hospitals NHS Trust, Basingstoke Hospital (original pilot centre)
    - Imperial College Healthcare NHS Trust
    - Musgrove Park Hospital, Taunton
    - Maidstone Hospital, Kent
    - Southmead Hospital, Bristol
    - Whittington Hospital, London

    There are 4 additional centres that are currently going through set-up and will open soon.
