@lyricw He is correct; positive margins are the biggest factor in the possibility of recurrence.
What it’s saying is that cancer cells are present even at the very edge of the specimen; so there are probably some cells still there in the bed and possibly beyond.
As previously stated you could initiate adjuvant therapy now by starting ADT to prevent spread and growth and then have radiation about 3 months post surgery. Or you can monitor PSA’s at 3 month intervals and start ADT/SRT after 3 consecutive increases in PSA even before it reaches 0.2.
The choice is really yours depending on how proactive you want to be or how you deal with anxiety and the emotional upheaval of living from blood test to blood test.
My own personality demands that I go all in early on, since the waiting is more harmful to my health than the disease itself! Best,
