Introduction: Although PSA screening has been rationalized, prostate cancer continues to have the highest incidence rate in 2021, and alone accounts for 26% of cancer diagnoses in men. A thorough review of the medical literature highlights a vast array of approved and investigational treatments for prostate cancer. Thus, selecting the best treatment option for the appropriate patient at the right time is crucial. Hence, biomarkers help in defining optimal patient stratification, revealing potential processes through which a drug might exert its impact and aid in the tailoring of treatments for efficient personalized medicine.
Areas covered: This article is a pragmatic review of novel prostate cancer therapies that can help guide clinicians in tackling prostate cancer with the latest treatments.
Expert opinion: Local radiotherapy has proven to be a game changer for low burden, de novo metastatic prostate cancer. Androgen deprivation therapy continues to be the ultimate treatment. Delaying resistance to these agents will undoubtedly be a breakthrough in the treatment of prostate cancer. When it comes to metastatic castrate-resistant disease, treatment options become narrower. PARP inhibitors and N-terminal domain inhibitors offer new hope and have a synergistic effect, with immunotherapy adding promising agents to the therapeutic arsenal.
