Brief summary
This will be a prospective diagnostic trial of screening for prostate cancer among men with genetic predisposition.
Detailed description
This will be a prospective diagnostic trial of screening for prostate cancer among men with genetic predisposition. The target population is males (40-70 year old) carrying a BRCA1 and/or BRCA2 germ line mutation. They will be identified via our Genetic counseling unit. All men after signing an informed consent will undergo the following tests: PSA, free to total PSA, MRI of prostate and prostate biopsy. The primary endpoint will be to estimate the prevalence, stage and grade of prostate cancer in this population. Additionally, the study aims to estimate the impact of these germ line mutations on benign prostatic hyperplasia. Furthermore, this study aims to create a bio-bank of tissue, urine and serum of this unique cohort for future investigations. Finally, this study will identify an inception cohort for future interventional studies of primary and secondary prevention.
Interventions
PSA. Serum & plasma will be stored for future investigations
the validated International Prostate Symptom Score
physical examination for the prostate gland
The post void residual will be recorded by using ultrasound. Creatinine level will be checked.
The MRI will be reported on a 5 point Likert Scale
12 core Trans-rectal prostatic biopsy for diagnostic purposes

Eligibility
Inclusion criteria
* Male carrier of mutation in BRCA 1\\2 or germ-line mutations in the MMR genes (MLH1, MSH2 , MSH6 or PMS2). * WHO performance status 0-2 (Appendix 2) * Absence of any psychological, familial, sociological or geographical situation potentially hampering compliance with the study protocol and follow-up schedule. * Individuals that cannot undergo the MRI exam due to high creatinine level or claustrophobic will be disc loud from the MRI part. * Informed written consent must be sought according to ICH/EU GCP, before subject registration.
Exclusion criteria
* Previous cancer with a terminal prognosis of less than five years. * Previous prostate cancer
