I was diagnosed in Dec 2014 with a psa of 199 which went up to 235by the time I started treatment.
I was told my PCa had spread and that I could not have radiotherapy or any ops.
The option was HT.
I was also offered a place on a Stampede Trial which included Abiraterone and Enzalutamide.
I started the Trial in January.
The abiraterone didn't agree with me so I dropped it.
Ever since I've been taking HT plus enzalutamide.
My psa dropped very quickly to .06 and has remained there ever since.
My next Oncologist appointment is next week.
I've had most of the side effects but for me enzalutamide has worked so far
Best of luck with your Dads treatment
