Evidence of the Link between Stroma Remodeling and Prostate Cancer Prognosis

Area of Science:

• Oncology
• Cancer Biology
• Biomarker Discovery

Background:

• Prostate cancer (PCa) is a leading cancer diagnosis in men globally, posing challenges for accurate prognosis.
• Current PCa management faces drawbacks, fueling research for molecular biomarkers to prevent overtreatment of indolent tumors.
• Understanding cancer pathogenesis now includes examining the tumor microenvironment, not just cancer cells.

Purpose of the Study:

• To provide an updated overview of prognosis-oriented microenvironment biomarkers in prostate cancer.
• To highlight key markers from reactive processes like tissue adaptation, inflammation, and metabolic reprogramming in PCa pathogenesis.
• To identify biomarkers for improved clinical management and reduced overtreatment in PCa patients.

Main Methods:

• Review and synthesis of current literature on PCa tumor microenvironment biomarkers.
• Focus on markers derived from stromal cell differentiation, cancer-normal cell crosstalk, angiogenesis, ECM remodeling, and energy metabolism.
• Analysis of biologically significant and highly cited prognostic markers.

Main Results:

• The tumor microenvironment of PCa offers promising prognostic biomarkers.
• Key reactive processes in PCa pathogenesis yield significant markers related to stroma, inflammation, and metabolism.
• Identified biomarkers target stromal cell differentiation, cell communication, blood vessel formation, tissue structure, and cellular energy.

Conclusions:

• The tumor microenvironment is a critical source for novel prostate cancer prognostic biomarkers.
• These biomarkers can aid in distinguishing aggressive PCa from indolent forms, guiding treatment decisions.
• Further research into these microenvironment markers holds potential for refining PCa management and avoiding overtreatment.
