Hi Billy
My OH was on stampede arm G which was Hormone treatment and Abiraterone as well as Radiotherapy - so similar to what you are on, plus as we are a few years ahead of you our results have been published.
The Arm G results were very encouraging and I believe that men are now being given Abiraterone earlier in their treatment as a direct result of this trial.
We too stayed on HT for 3 years, so like you, a year after finishing the other drug/s.
For us the PSA remained the same as it was all along even after stopping taking the additional drugs. Whilst on the HT the PSA remained at its lowest level.
I hope that this helps you.
All the best
Alison
