Info on AML?

My wife was recently diagnosed with acute myelogenous leukemia. Everything I look up has different information. One thing I read said the 5 yr survival rate was only 15% whereas another thing said anywhere from 30-50%. It also said after chemo, remission rate was around 85% but long term prognosis was not good. Her hemotologist won''t give a straight answer (yes we're going to see a different one...myself, an oncologist in our family, and her GP aren't even 100% convinced it is AML at all) I realize there are different forms of AML, and I think it's monocytic, but again, the doctor refuses to talk in "everyday language". Does anyone have any solid information on this? I'm going crazy here. She's a white 65y/o with a history of b12 deficiency, one minor stroke, Lyme disease and severe anemia(long time ago). But other than that, no other health issues.
