As has already been mentioned, get the following asap:
- PSMA
- Genetic test
- Decipher

This will give you important additional information as you see other doctors.

Does your Biopsy report mention cribriforms or intraductal?

Being in Germany, also look at the Martini Klinik in Hamburg (belongs to the university of Hamburg) and the Klinik für Urologie in Gronau (NRW). Germany has some of the very best specialists for PCa. Unfortunately, there are also some private clinics peddling unproven treatments, stay clear of those.
