Prostate cancer is common, but PSMA-targeted radiotheranostics offer new diagnostic and therapeutic options. This review explores their mechanisms, applications, and challenges in treating prostate cancer.
Area of Science:
- Oncology
- Nuclear Medicine
- Radiopharmaceutical Therapy
Background:
- Prostate cancer affects millions, necessitating advanced treatment strategies.
- Prostate-specific membrane antigen (PSMA) is a key molecular target for prostate cancer.
- Radiotheranostics combine diagnostic imaging and targeted radionuclide therapy.
Purpose of the Study:
- To review the molecular mechanisms of PSMA in prostate cancer.
- To explore the clinical applications of PSMA-targeted radiotheranostics.
- To examine the challenges in implementing these advanced therapies.
Main Methods:
- Review of approved and investigational PSMA-targeted radiodiagnostic and radiotherapeutic agents.
- Discussion of various radionuclides (e.g., 177Lu, 225Ac, 223Ra) and their characteristics.
- Analysis of clinical trial data and regulatory approvals.
Main Results:
- Several PSMA-targeted agents ([18F]DCFPyL, [18F]rhPSMA-7.3, [68Ga]Ga-PSMA-11, [177Lu]Lu-PSMA-617) are approved for prostate cancer.
- [177Lu]Lu-PSMA-617 (PLUVICTO®) approval marks a significant advancement for metastatic castration-resistant prostate cancer.
- Multiple radionuclides are under investigation for broader clinical implementation.
Conclusions:
- PSMA-targeted radiotheranostics represent a significant advancement in prostate cancer management.
- Further research and clinical trials are crucial to overcome implementation challenges.
- These therapies hold promise for personalized treatment of prostate cancer.
