Xtandi for the win (I hope)

For some strange reason I have a hard time believing this, but it is what it is.

Da Vinci RP in June 2007. All good until August 2014.

Beginning in August of last year my PSA readings began to increase and it's been steadily upward ever since, reaching 49.7 last month.

I've been taking Zytiga for the last four months which has had no affect at all on my PSA levels. I started on Xtandi a week ago. Monday of this week I went to the lab to have blood drawn for my monthly PSA test.

Today (Wednesday) I went to see the oncologist and he told me that my PSA had dropped from 49 to 31 !!!!!!!

So four days on Xtandi = an 18 point drop in PSA.

I'm having a difficult time with this. Four days on a new med drops my PSA 18 points !!!??? So is this a fluke, a statistical aberration of some kind?

The oncologist didn't question this, so the only way to be sure this isn't an anomaly of some kind is to have another PSA test. That will happen in 4 weeks and then I will know for sure.

Wish me luck.
