Radioligand Therapy in Prostate Cancer – Summary
Geoffrey B. Johnson, MD, PhD, Chair of the Division of Nuclear Medicine at the Mayo Clinic in Rochester, MN, discusses radioligand therapy in prostate cancer. Dr. Johnson briefly reviews the specific activity of this therapy, with a focus on Lutetium-177-PSMA-617.
Dr. Johnson highlights the benefits and tolerable side-effects of Lutetium-177-PSMA-617, and mentions the therapy is approved for patients with metastatic castrate-resistant prostate cancer who have been previously treated with androgen receptor pathway inhibition and taxane-based therapy.
The presentation further explores the process of patient selection for PSMA imaging, with the requirement of at least one lesion that shows higher PSMA expression than the liver. Dr. Johnson showcases post-therapy imaging examples, and discusses the potential of advanced scanning techniques, such as CZT-based scanners, which offer higher sensitivity and faster scans for accurate tracking of therapy response.
Dr. Johnson emphasizes the promising future of radionuclide therapy. He mentions the potential combinations of PSMA therapy with hormonal therapy, chemotherapy, immunotherapy, and external radiation. Additionally, he mentions ongoing trials exploring the use of alpha and beta emitters and the incorporation of different targets.
