Hello, Cindy. So sorry that your dear Lauren is ill. My husband was diagnosed april 04 and stayed in Gleevec 400 for 18 months. Now they increased to 600, but at long last he decided to undergo Bmt in short. I can imagine how hard it must be for you, children hurt a lot but probably and fortunately they don't suffer as much as we do. Mine are 10 and 12, two boys.
I read in many places that BMT is more succesful the younger you are and the sooner you do it. I suppose you don't have a perfect match donor for her(a sibling is the best, but if there isn't, stop thinking about this possibility). Then I suppose docs should be looking for an unrelated donor. This will most probably work beacause she's a child 0nly 19 years). It will be hard but it will pass and you'll forget the nightmare. If there's a cure BMT is the only way.
I teach maths, I have a pupil 15 years old with CML for long, she had a BMT from an unrelated donor several years ago. Then, at some stage, illness reappeared. She's now on Gleevec 400 and doing well. Her bad cells have dissapeared and the donor's good cells have come again. Doesn't sound like a miracle!
Try BMT, if it doesn't work, you'll always have Gleevec. But do thint it will work. You and your Lauren will win. This is my opinion.
I'll keep you in my prayers and love to your dear Lauren, strength and faith for yourself. Alicia.
