Impact of DNA damage repair alterations on prostate cancer progression and metastasis

Area of Science:

• Oncology
• Genetics
• Molecular Biology

Background:

• Prostate cancer is a leading global disease with significant unmet needs in advanced stages.
• Current treatments offer limited success for patients with advanced prostate cancer.
• Understanding molecular drivers is crucial for improving treatment strategies and clinical trials.

Purpose of the Study:

• To review the prevalence of DNA damage response (DDR) alterations in prostate cancer.
• To discuss the impact of DDR alterations on aggressive disease phenotypes and patient prognosis.
• To explore the association between germline DDR gene alterations and prostate cancer risk.

Main Methods:

• Literature review of studies on DNA damage response (DDR) pathways in prostate cancer.
• Analysis of the prevalence of DDR alterations in primary and advanced prostate cancer.
• Examination of the clinical implications of DDR alterations, including prognosis and risk association.

Main Results:

• Alterations in the DNA damage response (DDR) pathway, including homologous recombination repair (HRR) genes like BRCA1/2, are prevalent in advanced prostate cancer.
• These DDR alterations are particularly common in metastatic disease.
• Germline pathogenic alterations in DDR genes are associated with an increased risk of developing prostate cancer.

Conclusions:

• DNA damage response (DDR) pathway alterations are significant molecular determinants in prostate cancer progression.
• Understanding DDR alterations can inform the development of targeted therapies and improve clinical trial design for advanced prostate cancer.
• Investigating DDR gene alterations offers insights into prostate cancer risk and aggressive phenotypes.
