Katherine,
My pre-transplant regimen was very different from yours, but with the exception of Fludarabine, I had the same stuff:
Day -7 through Day -4 - Total Body Irradiation
Day -3 and Day -2 - Cytoxan
Day -1 - Rest (no treatments)
Day 0 - Transplant
I was very worried about the cytoxan because of all the ugly things we know about what chemotherapy does to people. Some people breeze through radiation and then get quite sick from chemo. I was the opposite, very sick during TBI treatment, but fine during chemo. The amount of radiation you will have is substantially less that what I got -- in part because the protocols have continued to improve and less harsh doses are possible.
I also had Methotrexate on a slightly different schedule, but I don't remember any particular side effects of that.
My story is posted
here. Don't hesitate to ask me about any of it.
Regards,
Ruth
