Emerging Relationship between the Gut Microbiome and Prostate Cancer

Area of Science:

• Microbiology
• Oncology
• Gastroenterology

Background:

• The human gut microbiota composition is influenced by environmental and genetic factors, impacting overall health.
• The gut microbiome's role in non-intestinal diseases, particularly cancer, is a growing area of research.
• A connection between the gut microbiota and prostate cancer, including its progression and treatment response, is increasingly recognized.

Purpose of the Study:

• To review the current evidence on the relationship between the gut microbiome and prostate cancer.
• To explore the mechanisms by which the gut microbiome may influence prostate cancer biology.
• To introduce the concept of the "gut-prostate axis".

Main Methods:

• This review synthesizes findings from existing basic and clinical research studies.
• Evidence from studies examining bacterial composition in relation to prostate cancer characteristics was considered.
• Mechanisms involving microbial metabolites and their impact on prostate cancer were analyzed.

Main Results:

• Gut microbiota composition varies with prostate cancer characteristics, such as histological grade and castration resistance.
• Specific intestinal bacteria are implicated in testosterone metabolism, potentially affecting prostate cancer.
• Microbial metabolites and components play a role in prostate cancer biology through various pathways.

Conclusions:

• A significant "gut-prostate axis" exists, linking the gut microbiome to prostate cancer.
• The gut microbiome influences prostate cancer progression and therapeutic efficacy.
• Further research into the gut-prostate axis could reveal novel diagnostic and therapeutic strategies.
