Prostate Screening Study Using MRI in BRCA Carriers
Sponsor: Toronto Sunnybrook Regional Cancer Centre
Summary
Men with a BRCA1 or BRCA2 mutation are at increased risk for early onset, aggressive prostate cancer compared to men in the general population. Standard of care screening for men with a BRCA mutation includes PSA testing and digital rectal examination (DRE), the same as with men in the general population. This study is being done to assess whether there is value in using MRI as a screening tool to detect prostate cancer at an earlier stage than may otherwise be detected using standard of care screening (PSA, DRE). It is unclear whether MRI has utility as a screening tool in this specific population at high risk for aggressive disease.

MS3TMRI / TRUS Guided Biopsy
Patients would undergo MS3TMRI and then have a transrectal ultrasound (TRUS) biopsy performed within one month after the MRI. The initial cores would be obtained using TRUS without MRI information (TRUSBx). During the same biopsy session, the MS3TMRI information would be given to the physician performing the biopsy and additional cores specifically targeted to suspicious areas would be performed (MS3TMRI-TRUSBx).
MS3TMRI / TRUS Guided Biopsy
Multispectral 3T MRI (MS3TMRI) is a device that uses a 3T MRI system without an endorectal receiver coil and with a surface phased array coil. 3T MRI in addition to established computer aided diagnosis (CAD) has been used to perform guided biopsies in an active surveillance population and demonstrated a positive predictive value and negative predictive value of 83% and 81%. A recently completed a study looking at repeat prostate biopsies in men followed on an active surveillance population at Sunnybrook has shown that the PPV of MS3TMRI guided biopsy to be 85%, while the negative predictive value was 100% (Haider, Vesprini and Milot, unpublished).
