My path was very similar to your father's - went from very healthy to (within a couple of months) stage IV prostate cancer, similar Gleason and off the chart PSA. It has since metastazide throughout my bones. I light up like a Christmas tree.
I am now eighty years old and four years into this journey. My treatments of Elegard, Keytruda, etc. have basically all run their course and are no longer effective. I opted to not have chemotherapy because it made no sense to me to kill off the good with the bad and hope that the good comes back faster than the bad.
I have just had my first treatment of Pluvecto, the latest version of radiation treatment, which does NOT work like chemotherapy but instead is targeted to the cancer cells. This treatment is a painless IV but it makes you radioactive for a while and you need to pretty much isolate and quarantine yourself for a week or so . Treatments are once every six weeks for a total of six times. I got through the isolation period ok with the biggest problem being boredom and constipation. My pain level has gone from a constant four to just mildly annoying and negligible, so I have to say that for me this treatment is working well.
Mental attitude, diet and continued exercise all play a major role in your well being. I also do non FDA approved energy healing with the spooky2 rife technology. I value quality of life over quantity of life.
The cancer has taken my strength and stamina levels down to maybe 20% of what they used to be, but other than that I feel relatively ok. Just can't do a whole lot and need to be very conscious of pacing myself in any physical activities.
Hope my experiences are helpful to you.
