Startech, my stats are similar to yours and I wrestled with the same issue for a while...to do ART or wait for BCR and go for SRT. I consulted a couple of different docs and was told that if you have continence issues before ART you will be incontinent after ART. ED issues here as well and now I have a chance. After ART very unlikely that will work again. Then because I am 53 there was concern that bowel issues or bladder cancer may pop up down the road as a SE of radiation. The most recent study indicates that there is an advantage to ART over SRT for TX of PCa. 40% will benefit while 60% will not experience BCR even without further treatment. So, to save 40%, 60% would be treated unnecessarily and have do risk the SEs that go with it. I finally decided to wait for BCR and let the chips fall where they may. It isn't an easy decision but that's where I stand and my reasoning for it. Neither of the docs I consulted recommended ART for me. Not sure if that will help but I feel your dilemma...it really bothered me for quite a while until I made my own decision.
