Hello mate.
Welcome to the forum, thanks for posting.
I'm sorry to hear about your father and brother. Both my dad and my younger brother were also diagnosed with it. Fortunately, my dad died with it, rather than from it, and my brother, like me, appears to be recovering from it.
Your case shows that PSA testing is only an indicator. We've seen cases where high PSA levels have no or low grade cancer, and others where low PSA levels have shown high grade disease. I think research is being done to try and improve PSA testing and reduce these apparent anomalies.
My post prostatectomy showed I was T3a, N0 M0. Gleason 9 (4+5) yet for years my PSA levels were lowish fluctuating between 4 and 5. I always thought that there would be a direct correlation between PSA and Gleason score, but this obviously not always the case.
Unfortunately, high grade PCa producing low PSA tends to lead to worse outcomes. As recent research shows:

I see that your were a T2c staging, which indicates the cancer was in both lobes but prostate confined. I'm a bit confused how you can have lymph node involvement with a T2 staging. Perhaps someone would be kind enough to inform me.
When do you finish your Abiraterone and Zoladex?
I very pleased to see that your PSA level has remained undetectable for over a year now, long may it continue.👍
