Abstract:
Despite chemotherapy and novel androgen-receptor signalling inhibitors (ARSi) have been approved during the last decades, metastatic castration-resistant prostate cancer (mCRPC) remains a lethal disease with poor clinical outcomes. Several studies found that germline or acquired DNA damage repair (DDR) defects affect a high percentage of mCRPC patients. Among DDR defects, BRCA mutations show relevant clinical implications. BRCA mutations are associated with adverse clinical features in primary tumors and with poor outcomes in patients with mCRPC. In addition, BRCA mutations predict good response to poly-ADP ribose polymerase (PARP) inhibitors, such as olaparib, rucaparib, and niraparib. However, concerns still remain on the role of extensive mutational testing in prostate cancer patients, given the implications for patients and for their progeny. The present comprehensive review attempts to provide an overview of BRCA mutations in prostate cancer, focusing on their prognostic and predictive roles.
Insights
Germline DNA damage repair (DDR) defects, particularly BRCA mutations, impact metastatic castration-resistant prostate cancer (mCRPC) outcomes. These mutations predict response to PARP inhibitors but raise concerns regarding genetic testing implications.
Area of Science:
- Oncology
- Genetics
- Medical Research
Background:
- Metastatic castration-resistant prostate cancer (mCRPC) has poor outcomes despite current therapies.
- DNA damage repair (DDR) defects, including BRCA mutations, are prevalent in mCRPC.
- BRCA mutations are linked to adverse tumor features and poor prognosis in mCRPC.
Purpose of the Study:
- To review the prognostic and predictive roles of BRCA mutations in prostate cancer.
- To discuss the clinical implications of BRCA mutations in mCRPC.
- To explore the utility of mutational testing for prostate cancer patients.
Main Methods:
- Comprehensive literature review.
- Analysis of studies on BRCA mutations in prostate cancer.
- Evaluation of prognostic and predictive data.
Main Results:
- BRCA mutations are associated with poor outcomes in mCRPC.
- BRCA mutations predict a favorable response to poly-ADP ribose polymerase (PARP) inhibitors.
- Concerns exist regarding the implications of widespread genetic testing for patients and families.
Conclusions:
- BRCA mutations have significant prognostic and predictive value in prostate cancer.
- PARP inhibitors offer a targeted therapy option for mCRPC patients with BRCA mutations.
- Further consideration is needed for the ethical and clinical aspects of genetic testing in prostate cancer.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
