Welcome to HW. Sorry to hear about your rapid PSA rise.
It would appear that your PCa is systemic, and may have started growing in another location. With your capuslar penetration, and seminal vessical invasion, you have multiple area for it to escape.
I would find an oncologist soon, and start to discuss the next steps, which most likely will be some form of hormone therapy. Be sure and find someone who is experieced in HT. most likely not your urologist. HT is a specialty that not everyone is well versed in.
We have guys on here who had PSA's greater than 3000 who are still doing well. This is not the time to panic. By using HT correctly, you can fight this thing for nmany years.
Good luck on your journey. This is a great place to be.
