Thanks, Gary- like I said -Duhhh- I did some looking too and got just about as helpful information- don't know anyone here who got a stem cell transplant. But I have seen "Induction chemo" posted alot here, so I was curious. Maybe Tom can get a defination that applies to Head and Neck cancer that we can relate to. Mark D's answer made sense to me. And I appreciated his post because I know he is busy doing the laundry. Amy
