Tumor-associated antigen targets for novel immune-based strategies in prostate cancer

Prostate cancer remains the most common malignancy among men in the United States. Advancements in androgen receptor signaling blockade have led to landmark approvals for its use in patients with locally advanced and metastatic disease. However, additional novel therapeutic strategies for both hormone -sensitive and castration -resistant diseases remain ongoing areas of study. Thus, we turn to the growth of immuno-oncology, which has led to improved treatment outcomes for a variety of hematologic and solid tumor malignancies. Prostate cancers have shown only modest results with immune checkpoint inhibition in published trials, and innovative strategies are now looking into enhancing cytotoxic T -cell activity against cancer cells. This review provides a thorough evaluation of tumor -associated antigens that are integrated into novel chimeric antigen receptor T -cell and bispecific T -cell engager therapies. Our review will evaluate the most recent advancements in immunotherapies, while also illustrating major obstacles and underlying limiting factors.
