Hi Rod,
What was your original Gleason score ? My partner has a very aggressive disease, too late for RP but I would be inclined not to hang around and wait if possibility disease is in lymph glands, just my opinion of course. Bear in mind that PSA isnt always a good marker of the disease, it's possible to have spread and a low PSA, just as well to be mindful of all these things, having a look at others' threads soon demonstrates how complex PCa is. Hopefully , you will get some further comments,
Best wishes, Fiona.
