Simple Summary: Prostate cancer presents significant challenges due to its high incidence and prevalence, as it is the most common non-skin cancer in men. The timely detection of prostate cancer and its metastasis is crucial for patient outcomes. Prostate-specific membrane antigen (PSMA) emerges as a promising biomarker for its early detection, due to its specificity and membrane localization on tumor cells. Utilizing PSMA-targeting particles in conjunction with positron emission tomography (PET) scans enhances the accuracy of tumor detection compared to PET alone. This advancement has led to innovative treatment modalities such as Prostate-specific membrane antigen-targeted radionuclide therapies (PSMA-TRTs), which have shown promise in reducing or eliminating tumors, as evidenced by declines in prostate-specific antigen (PSA) levels post treatment. However, PSMA-TRT carries both benefits and adverse effects, with the long-term ones as yet unknown. The short-term adverse effects include fatigue, nausea, pain flares, and potential radiation exposure to others. Further research is needed to explore PSMA-TRT's long-term efficacy and potential applications beyond prostate cancer. Prostate cancer is one of the most challenging malignancies due to its high incidence and prevalence, as it is the most frequently diagnosed non-skin cancer in men. The timely identification of prostate cancer and its metastasis is paramount for ensuring favorable outcomes for patients. Prostate-specific membrane antigen (PSMA) emerges as a promising biomarker for its detection, due to its specificity. This makes it an ideal target for the early identification of a metastatic phenotype. Situated on the membrane of tumor cells, PSMA facilitates the attachment of PSMA-targeting particles, enabling their detection through positron emission tomography (PET) scans with relative ease. Utilizing these imaging agents in conjunction with PET scans enhances the accuracy of prostate cancer tumor detection compared to PET scans alone. The advancement in prostate cancer imaging has paved the way for innovative treatment modalities. Prostate-specific membrane antigen-targeted radionuclide therapies (PSMA-TRT) exploit PSMA imaging agents to target identified prostate cancer malignancies with precise radiation, thereby reducing or eliminating the tumor mass. PSMA-TRT exhibits significant promise in prostate cancer therapy, evident from the notable declines in prostate-specific antigen (PSA) levels post treatment. However, PSMA-TRT carries both beneficial and adverse effects. While it represents a substantial leap forward in tumor cell imaging, PSMA-based antigens, being larger particles than ligands, offer prolonged imaging capabilities. Yet, the long-term effects of PSMA-TRT remain unknown, with the short-term adverse ones including fatigue, nausea, pain flares, and potential radiation exposure to others. [ABSTRACT FROM AUTHOR]
