Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
a) Single treatment arm
b) multi-parametric MRI (mpMRI) prostate followed either by MRI prostate biopsy and ultrasound prostate biopsy; OR ultrasound prostate biopsy alone
Decision to perform MRI guided biopsy is based on MRI findings using PIRADS scoring system (Eur Radiol. 2012 Apr;22(4):746-57. Epub 2012 Feb 10.
) - PIRADS 1 and 2 scored MRI patients only have TRUS biopsy
- patients with MRI scored 3,4 or 5 have both an MRI guided biopsy and TRUS biopsy
c) MRI prostate - 30min; MRI prostate biopsy 40 min; US biopsy of prostate - 15 min
d) Modes - MRI and ultrasound imaging of the prostate

Outcomes
Primary outcome [1] 287845 0
1. Accuracy in detection of the most aggressive prostate cancer present for mpMRI and mpMRI-guided biopsies vs. TRUS-guided biopsies for all patients by comparing biopsy results of mpMRI biopsies against TRUS guided biopsies in each patient with PIRADS score 3,4 or 5. For Patients with PIRADS score 1,2 only the mpMRI images will be compared to the biopsy results of the TRUS guided biopsies

Eligibility
Key inclusion criteria
1. Men referred to a urologist with a high or concerning PSA, or abnormal prostatic rectal examination. These men would normally proceed to TRUS biopsy under current guidelines.
Minimum age
No limit
Maximum age
No limit
Gender
Males
Can healthy volunteers participate?
No
Key exclusion criteria
1. Men who have had a TRUS biopsy in the past
2. Men taking 5 alpha reductase inhibitors.
3. Men who are unwilling or unfit to undergo prostate biopsies (in the opinion of the referring urologist)

Study design
Purpose of the study
Diagnosis
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients referred to the clinical trial by a urologist will be assessed by the trial team to ensure inclusion and exclusion criteria are met.
This is a non-randomzied trial in that every patient will receive both the current gold standard diagnostic test - TRUS guided prostate biopsy, as well as undergoing a mpMRI and mpMRI guided biopsy of any MRI detected lesions
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization not necessary as each patient will undergo both diagnositic interventions
Masking / blinding
Open (masking not used)

Summary
Brief summary
The study is evaluating a novel diagnostic technique for prostate cancer, known as multi-parametric magnetic resonance imaging (mpMRI).

Who is it for?
You may be eligible to join this study if you are a male who has been referred to a urologist with a high or concerning PSA (Prostate-specific antigen), or abnormal prostatic rectal examination.

Trial details
All participants in this study will undergo current treatment guidelines for diagnosis of prostate cancer, including PSA measurements and 12 core Transrectal ultrasound (TRUS) guided needle biopsies of the prostate. In addition, a highly specific imaging process, known as multi-parametric magnetic resonance imaging (multiparametric MRI or mpMRI), will be used to further assess the prostate gland and be used to take MRI guided biopsy of any MRI detected lesions. This examination takes 20-30 minutes and involves the administration of a gadolinium contrast agent.

It is anticipated that the results of this study will lead to better informed treatment of prostate cancer and suspected prostate cancer, for example by decreasing the number of men who need biopsies, decreasing the number of biopsy cores in those men who need them from 12 to 2 or 3, and decreasing the overtreatment of non-significant prostate cancer
