Abstract

Objective: Prostate Cancer (PCa) is a leading cause of cancer-related mortality in men, especially in Western societies. The objective of this research is to address the unmet need for effective treatments in advanced or recurrent PCa, where current strategies fall short of offering a cure. The focus is on leveraging immunotherapy and cancer vaccines to target the tumor's unique immunological microenvironment.

Main results: Despite immunotherapy's success in other cancers, its effectiveness in PCa has been limited by the tumor's immunosuppressive characteristics. However, cancer vaccines that engage Tumor-Specific Antigens (TSA) and Tumor-Associated Antigens (TAA) have emerged as a promising approach. Preclinical and clinical investigations of Dendritic Cell (DC) vaccines, DNA vaccines, mRNA vaccines, peptide vaccines, and viral vectors have shown their potential to elicit anti-tumor immune responses. The exploration of combination therapies with immune checkpoint inhibitors and the advent of novel adjuvants and oral microparticle vaccines present innovative strategies to improve efficacy and compliance.

Conclusion: The development of cancer vaccines for PCa holds significant potential. Future directions include optimizing vaccine design, refining combination therapy strategies, and creating patient-friendly administration methods. The integration of interdisciplinary knowledge and innovative clinical trial designs is essential for advancing personalized and precision immunotherapy for PCa.
