I, too, had triplet therapy and Radiation to isolated met to my lumbar spine and whole pelvic radiation as well. After second chemo treatment over a year ago my PSA became undetectable. Now off all medications. Monitoring PSA and testosterone.
The diagnosis is obviously anxiety provoking to me and anyone with this disease. I was treated at Johns Hopkins with the Radiation Therapy at Emory. My very experienced MO at Hopkins said I have 5 years for sure but he didn't know about 10. He is honest and blunt. However, I am hopeful about the longer term outlook. Should my PSA go up and PSMA PET reveal another met or 2, the plan is to use SBRT to kill the tumor and perhaps a short (3 month) term course of ADT. As the treatment is progressing at such a rapid rate, there really is no definitive SOC and that is why I wanted an experienced MO with prostate specialization directing my care. I want aggressive treatment but I also want quality of life.
Good luck to you and all on this going through this journey.
