I asked because you wrote "pT3aN0M0." I guess you meant NX.
Well then, if you were trying to figure out your odds of LN invasion based on your Gleason score and initial PSA, it would be 2/3 x 8.4 + (7-6)x10 = 5.6 + 10 =15.6%. Roach recommends LN radiation when your odds are over 15 - so you are right at the cusp (no clear decision from that). Your PET/CT showed no enlargements there, so it seems
to be clear. That's about
all I can tell you. I see why your doctor left it up to you - only you can decide if that risk of cancer there is worth the risk of SEs from the radiation.
