In December 2017 my father had TURP . After biopsy we came to know that he has adenocarcinoma with Gleason score 2+4=6
Bone scan confirm the bone mets.
His PSA was 228 (high due to surgery)
We consult oncologist he prescribed
Zoladex +calutide for January
Zoladex+calutide for February
Then he put only him on calutide
His PSA on April 2018 is 0.978
His PSA on September is 2.5
His PSA on November is 11.3
Doctor said he has now Castration resistance prostate cancer hormone therapy not working more
He now prescribed on December
Casodex + zoladex
His PSA today 31 dec 2018 is Reduced to 9.5
Is he really Castration resistance stage ??
In Castration resistance the can PSA drop 2 points in a month?
What is the treatment at castration stage?
