Introduction & Objective: Men with abnormal digital rectal examination or raised PSA usually undergo
transrectal ultrasound (TRUS) prostate biopsies. NICE guidelines do not recommend routine MRI prostate before prostate biopsy unless they have a previous negative prostate biopsy. However, all men with positive prostate biopsies will have MRI prostates. The recent publication of PROMIS (Prostate MR Imaging Study) trial suggests that MRI prostate can reduce unnecessary biopsies by a quarter and can improve detection of clinically significant cancer. In light of this, we would like to determine if performing MRI prostate before biopsy is likely to increase workload in our radiology department in a district general hospital in the UK. Materials and Methods: Patients who underwent TRUS prostate biopsy between 3 Dec 2015 to 28 April 2016 were identified. Their data were analysed retrospectively. 1 year follow-up was chosen to see how many patients would have had MRIs. Results: 173 patients were listed for prostate biopsies but only 158 patients had biopsies with an average age of 69.8 years old (range: 49-88 years old) and an average PSA of 48.1ug/l (range: 0.5-3283.1ug/l). 57 patients had a negative prostate biopsy during this period. 30/57 patients did not have a MRI at all; 12/57 patients had a MRI after biopsy; 1/57 patient had a MRI as an acute setting after biopsy to look for abscesses; and 14/57 patients had a MRI before biopsy. Conclusions: In our study, 30/158 (19.0%) did not have any MRI prostate in 1 year after their first prostate biopsy. However, it is possible that this group of patients will have a MRI prostate in the second year or later. If we were to perform a MRI prostate before TRUS prostate biopsy for all patients, it would increase 19.0% workload for our radiology department.
