I am T3bN1 meaning the thing has broken out of the prostate into the seminal vesicles and at least 1 lymph node.
RP out of question, so oncologist had an easy decision, external beam radiation and High Dose Radiation therapy with HT for at least 2 years. Absolutely no choice but to go with that and brace myself for whatever side effect package comes. I did my digging up but most sources quite unclear, saying oh depends on individuals, some can be really bad, external beam only is adequate etc... Didn't know what to do. Go for external only and then find myself having to do the Brachy again later? or go for both at same time and risk those nasty side effects? So have started the external beam or EBRT and due to go for the brachy HDR beginning of November. If this is a mistake, please people, shout as I can still change and go for the EBRT and HT only. My oncologist insists on all three. I will keep you all posted.
So, in answer to your question, I agree, T3b would most likely mean there is a node affected. It does look like RT needs serious consideration?
Good luck.
