That time span is good to hear. I'm so frightened of the time when my mCSPC eventually turns castrate-resistant, and to hear that you've been going for 10 years with mCRPC lets me hope a little more.

Another thing to remember is that "overall survival" (OS) means the median time to end of life from ANY cause, not just cancer or side-effects from cancer treatments like chemo. In one prostate cancer study I read, the average age of participants was in the mid 70s. While mid 70s is by no means ancient these days (runners that age used to pass me on the jogging path when I was in my 30s), and people are right to expect lots of active, healthy years ahead, many study participants will have passed away from causes other than the prostate-cancer itself during the research period For those of us diagnosed in our 50s or 60s, the median OS numbers are a little tickier to make sense of.
