I Had A Prostectomy In November 2012. Post Surgery My

I had a prostectomy in November 2012. Post surgery my PSA was undetectable. About one year ago my PSA moved up .1, then seven months later to .2 and then after another seven months (a month ago) moved up to .3. I tried Lupron immediately after surgery, ugly in that I had tons of side effects. It appears that I am now facing salvage radiation. I am fearful of side effects, not so much now, but a couple of years down the line. Any clinical trials to your knowledge that does not include Lupron (or look alike) or radiation?
