My experience was fairly similar to Lags husband.

Went through all six treatments, then got a psma pet scan to check on results.

A couple of years ago I had a five session targeted radiation treatment. The psma pet scan showed one new cancerous spot coming just off the edge of one of the previous targeted radiation treatment spots (not related to the Pluvicto treatment).

Other then that, the psma pet scan showed the larger cancerous areas diminished by about half, the smaller areas of cancer gone, and no other new growth areas.

I am currently undergoing another series of five targeted radiation treatments for the one area which has appeared just off the old area that was previously treated with targeted radiation.

As far as PSA is concerned I have had eligard shots to keep my testosterone low. The theory is low testosterone results in low cancer growth, but I not found that to be true. All the eligard seems to do for me is keep my testosterone down. I see no effect one way or the other on my cancer. My testosterone is currently high, in the seventies, but I don't take that as a reliable market of imminent cancer doom.

I will have to see how I am in a few weeks after my current series of five targeted radiation treatments have run their course and settled in to determine what comes next. I know others who have successfully handled the Pluvicto treatment have now started on a second set of six rounds of Pluvicto. I am very open to going that route, but also want to see what, if anything else, allopathic medicine may have to offer.
