Greetings, I haven't posted before, but have been impressed by the courage and care shown by so many of you. I was diagnosed in 2007 (yeah, ten years ago) and had a robotic prostatectomy that November - they almost got it all. Gleason 5+4=9. Since then, I have failed salvage radiation, ADT, Casodex, radiation to the left humerus (incipient fracture), Zytiga+prednisone, Xtandi, and full replacement of the left shoulder. Now the cancer has changed to a soft tissue cancer - I have a number of lumps on my chest wall and in one case biopsy verified prostate cancer. There is a bone met in one rib, which is broken, likely pathological. PSA is at 31 with a doubling time of about 40 days. Good news: genetic analysis of the biopsy disclosed that it displays the MSI-H marker, which means that I can take Keytruda, which is FDA approved for that use. Bad news: Medicare B declines to cover it, they regard it as "experimental". Indeed, so far as I can tell, Keytruda has never been tested >alone< against PCa, only in combination, so their position is not totally irrational. And there seem to no ongoing trials alone either, so it probaby won't change soon.
If I have to pay for it, it's $9600 every three weeks, $166,000 per year, indefinitely. Can't do that.
Can one argue with Medicare? How? Their position does seem to be inconsistent with FDA.
Thanks for any advice!
I'm not a doctor, but I will offer my opinion. I think Keytruda has long odds for prostate cancer, plus I think you are unlikely to be successful with Medicare covering it.
I don't see that you've done any chemotherapy. The fact that the cancer has moved to soft tissue could be a sign that you've developed some "treatment related" neuroendocrine features. If that's the case, Platinum chemotherapy could be the best option for you. You can have your blood tested for Chromogranin A which is a substance commonly produced by neuroendocrine cancer cells. You can discuss all of this with your doctor. That's my 2 cents.
