Cutibacterium acnes: An Emerging Prostate Cancer Pathogen

Area of Science:

• Microbiology
• Oncology
• Immunology

Background:

• Cutibacterium acnes (C. acnes) is increasingly implicated in prostate cancer (PCa) pathogenesis.
• The precise mechanisms by which C. acnes influences PCa remain largely undefined.

Purpose of the Study:

• To review the prevalence, persistence, and mechanistic impact of C. acnes in the prostate.
• To evaluate the functional consequences and diagnostic potential of C. acnes infection in PCa.
• To clarify the role of C. acnes in PCa development and patient management.

Main Methods:

• Literature review of studies on C. acnes colonization in premalignant and malignant prostate tissue.
• Analysis of factors like hypoxia and low pH that may promote C. acnes persistence.
• Examination of research on C. acnes's modulation of inflammatory, immune, and cellular pathways.

Main Results:

• C. acnes colonizes both premalignant and malignant prostate tissues.
• Prostate tumor microenvironment characteristics may facilitate C. acnes persistence.
• C. acnes influences immune responses, DNA damage, host metabolism, and extracellular matrix.
• C. acnes presence in microbiome and circulation suggests diagnostic potential.

Conclusions:

• Further research is needed to determine if C. acnes is a biomarker, bystander, or driver of PCa.
• Understanding the C. acnes-PCa relationship can inform personalized diagnostics and screening strategies.
• Clarifying this link advances microbiome-cancer dynamics knowledge for improved patient care.
