Prostate Tissue BioBank
(PTBB)
What this study is about
Prostate cancer is also the most common cancer in men with inherited pathogenic variants in BRCA1 and BRCA2. Beyond BRCA1/2, other genes are known to increase the risk of prostate cancer, including ATM, TP53 and HOXB13.
View original scientific description
Prostate cancer is also the most common cancer in men with inherited pathogenic variants in BRCA1 and BRCA2. Beyond BRCA1/2, other genes are known to increase the risk of prostate cancer, including ATM, TP53 and HOXB13. The investigators have shown that 5% of men diagnosed with prostate cancer localized to their prostate gland and up to 10-15% of patients with metastatic prostate cancer gland are carriers of an inherited gene mutation. The Prostate Tissue BioBank is a prospective study which aims to create a biorepository of prostate tissue samples from prostate biopsies and prostatectomies and matched germline DNA from pathogenic mutation carriers in addition to age-matched control samples. Our primary goal is to investigate prostate cancer development and treatment response in carriers of germline DNA repair mutations, as compared to non-carrier controls.
Primary outcome measures
Clinical and pathological data for patients with prostate tissue samples
Time frame: 5 years
Data will be collected on consented patients who undergo prostate biopsy, prostatectomy or metastatic biopsy.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
