My 73 year old father was diagnosed with AS a couple of years ago which prompted me to go searching for information and I discovered the treatment protocol as described on Dr. Mercola's website. My father's physician has him on a low dose of a chemotherapy drug and some Prednisone. I know Daddy suffers still and I worry about the side effects of the chemo, but he trusts that his doctor knows best and won't mention this other information. I live 10 hrs. away and so don't really have any influence over his diet, supplements etc. Very frustrating for me! Anyway, I offer the link so perhaps someone can benefit....
