I need to correct @jeffmarc's comment. Pluvicto is a targeted therapy that binds to prostate-specific membrane antigen (PSMA), a protein found on prostate cancer cells.
Once bound, the radioactive component of Pluvicto releases radiation that kills the cancer cells, specially lutetium 177Lu, a highly radioactive compound. The treatment delivers gamma radiation that escapes your body and can reach others around you, especially within the first 3 days after each treatment.
I had a full 6 treatments of Pluvicto in 2021-22 as a clinical trial patient for Novartis Pharmaceutical. It was approved in the US shortly afterwards. In mid 2024, my cancer became active, again and I am one a just a handful of patients anywhere in the world repeating the 6 treatment program, completely at my own risk.
I've had numerous targeted beam radiation treatments including the prostate bed and countless PET CT scans and a recent SPECT scan. And, full chemo twice. Yes, lots of radiation. If you have reached the point of receiving Pluvicto, the LEAST of your concerns should be your life radiation accumulation. Yes, too much radiation can effect bone marrow and cause other issues, but those choices might already be out of your necessary, and life saving decision making moving forward. I'm 73, battling cancer for 10 years and so far, I'm doing remarkable well with none of the excessive radiation side effects. Good luck. Don't give up, do what you have to do.
