After a 10 year battle with PCa, I started Keytruda last December. UofM genetic analysis indicated Keytruda would probably work. After one infusion and three weeks time, my four subcutaneous tumors (yes! biopsy verified) had shrunk noticeably. Three weeks after the second infusion, the tumors had basically disappeared and PSA had dropped from 60 to 0.15! Today, three weeks after the third infusion, PSA was at " <.01 ". Undetectable.
I have had no ill effects during infusion and no side effects otherwise.
Medicare has covered 80% and private insurance the other 20%. Moral: if you have to have a biopsy done, consider having the genetic analysis done!
Best of luck to all you guys, there is hope!
