The PCa Tumor Microenvironment.

Area of Science:

• Oncology
• Cancer Biology
• Immunology

Background:

• The tumor microenvironment (TME) is a complex ecosystem comprising diverse cells, matrix, and soluble factors.
• Prostate cancer (PCa) progression is intricately linked to the crosstalk between tumor cells and the TME.
• The TME influences PCa by responding to tumor signals and actively shaping the tumor through its own factors.

Purpose of the Study:

• To review the host-derived components of the TME that influence prostate cancer progression.
• To provide a foundation for understanding the TME's role in PCa from the host's perspective.
• To highlight the TME as a potential therapeutic target for PCa.

Main Methods:

• Literature review focusing on host factors within the TME.
• Analysis of immune effector cells, specialized niches (vascular, bone marrow), and key protein factors.
• Synthesis of current understanding regarding TME-PCa interactions.

Main Results:

• The TME comprises host cells and recruited cells that interact dynamically with prostate cancer cells.
• Specific TME components, including immune cells and protein factors, mediate host effects on PCa.
• The TME orchestrates an evolutionary dialogue with the tumor, influencing its establishment and advancement.

Conclusions:

• The host-derived TME plays a critical role in prostate cancer progression.
• Targeting the TME offers a promising therapeutic strategy for managing PCa.
• Further research into TME components can uncover novel avenues for PCa treatment.
