Thank you jeff. I am also doing this research and finding my answers. There other patient who is 10 years younger then my dad. Probably 57 years old his gleason score was 9. He has started his treatment journey by taking testosterone ruduction injection every 3 months and then started zytiga for few months and then change to enzalutamide and he has been taking enzalutamide for 2 years now. He is so far doing good.
Only different thing he has done from us is not doing Orchidactomy instead 3 monthly injections and haven't gone on a chemo path.
