Prostate cancer may be preventable by targeting infection and inflammation, key drivers of its development. Later stages can be managed by targeting androgen signaling pathways.

Area of Science:

  • Oncology
  • Cancer Biology
  • Preventive Medicine

Background:

  • Prostate cancer is a significant cause of morbidity and mortality globally.
  • Understanding the mechanisms of prostate cancer development is crucial for prevention.
  • Recent insights into human prostatic carcinogenesis offer new avenues for prevention strategies.

Purpose of the Study:

  • To review prostate cancer prevention in light of new mechanistic insights.
  • To explore the roles of infection and inflammation in prostate cancer development.
  • To identify potential targets for prostate cancer prevention and treatment.

Main Methods:

  • Review of current scientific literature on prostate cancer.
  • Analysis of mechanistic insights into prostatic carcinogenesis.

  • Synthesis of evidence implicating infection, inflammation, and genetic alterations.

    • Main Results:

    • Infection and inflammation are increasingly implicated in prostate cancer development.
    • Inherited susceptibility genes are linked to host responses to infection.
    • Proliferative inflammatory atrophy serves as a precursor lesion, connecting inflammation to carcinogenesis.
    • Somatic epigenetic alterations and TMPRSS2-ETS gene fusions are observed in prostate cancer.
    • Androgen dependence of prostate cancer cells may be explained by specific gene fusions.

    Conclusions:

    • Prevention strategies should focus on infection control, inflammation amelioration, and reducing oxidative stress.
    • Targeting androgen signaling pathways, potentially with 5-alpha-reductase inhibitors, is a viable approach for later-stage prostate cancer.
