AML

hi i could sure use some advise, insight if anyone has had this experience, my sister was admitted to icu from doctors office 9/10/12, diagnosed with aml 9/11/12 and began chemo that day as she was very sick and told she would die within a couple of days without the chemo at the rate her wbc were increasing, i believe she was on a 7 day iv drip not sure of the chemo name. To make a long story short she is still in hosp.as of today 11/12/12 and has been in and out of icu to oncology floor with complications of fluid on lungs and heart, having to have the fluid drained off several times, she is in remission but has never been able to build up her own platelets, they have to give her blood and or platelets daily, she was unable to breath and walk until a couple of days ago after they drained her lung again (she was horribly sick for a couple of days) then finally her lungs were clear and she was dizzy but made it down the hall, the first in 2 months. She is diabetic on an insulin pump 58 yo, has no apetite. the doctor told me a couple weeks ago he is afraid he will lose her an now he says he wants to get her well enough to come home for a couple of days then send her to a bigger hosp to see about bone marrow transplant. This is very hard for me to understand why she cant build up platelets an get somewhat healthy after the chemo.
