Advanced prostate cancer is treated with lutetium PSMA therapy, sometimes referred to as lutetium-177 prostate-specific membrane antigen therapy or lutetium-177 PSMA therapy. The protein known as PSMA, or prostate-specific membrane antigen, is present on the outer surface of prostate cancer cells.
Lutetium In PSMA therapy, a chemical that precisely targets and binds to the PSMA protein on prostate cancer cells is used in conjunction with the radioactive isotope lutetium-177. This minimises radiation harm to neighbouring healthy tissues while allowing precision radiation delivery to the cancer cells
