From what I can decipher of the French, I believe your dad has positive margins, which means the cancer has spread outside the prostate.
What this probably means with Gleason 8 is that he will most likely require radiation also. Some would advise the radiation within 4 months of surgery, or adjuvant treatment, some would say wait until the PSA rises to a certain level, and then do it, called salvage radiation.
Gleason 8,9, and 10 are termed aggressive PC. They behave differently than the other Gleasons, and will need careful attention. He should be seeing the doctor every 3 months, and getting PSA tests. If you don't feel he is getting enough attention, a second opinion from an oncologist may be a good idea.
Good luck and welcome to HW.
