Bgharvery,
I was diagnosed with stage 4 prostate cancer in January of this year, three months after my prostate had been removed. It had spread to two lymph nodes and my bladder. Starting in February of 2020, I begun three treatments of chemotherapy which were not effective, and my PSA continued to rise. I had also started on hormone therapy.
Since the chemotherapy was not working, and with little precedent, I was put on immunotherapy (Opdivo), and my PSA went from 21 to 0.11 after one treatment. My treatment and PSA readings are done once every four weeks. After the 0.11 reading, my next three PSA readings were “undetectable”.
So, my oncologist and I are in uncharted waters with this treatment, but it does seem to be working. I will undergo a pelvic scan in October, which will be six months from the time of my first immunotherapy treatment. We are hoping to get more information about what exactly is going on with the cancer. The length of my treatment of immunotherapy and hormone therapy are to be determined. However, my side affects are minimal so continuing treatment for a year or more is not a problem.
My message is to not give up hope! When my chemotherapy was not working, and I had so much blood in my urine, I did not expect to recover. However, there are clinical trials and new treatments which might work for you. Keep trying!
