Not always the case, my father became castrate resistant in 2 months with Casodex but is currently on almost his 5th month on Zytiga and doing well so far, so if you fail first line ADT it doesn't necessarily mean that 2nd line ADT will last less. Every patient is unique and responds differently to different drugs.
I was wondering if someone is on the same path as my father, where second line ADT lasted more than first line ADT.
Thanks in advance.
