My father has had 10 rounds of chemo (his last one is this week), he went from a psa of 2000 to his current psa of 0.2, we started this journey in December last year and he has been on lupron since pretty early on (had some kidney issues and had it delayed the first month) he also was on casodex in the beginning.
His oncologist has mentioned starting him on zytiga after his infusions are over. I have read that zytiga is usually given further along and im worried about what the implications are. And if there are less treatment options after it?
Thank you for any feedback about the drug/treatment plan
