We got a call today from the Transplant Coordinator, telling us that the donor has been selected. They actually select the third of the three donors we had been undergoing testing — the last one to come in. This is good news — when we saw Dr. Rossetti, he had liked that second one a lot. And he likes this one better. This first choice is a young female, not from the U.S., same blood type as Bethany. She will be contacted with the news, and if she agrees to do it, she will be scheduled for a complete physical exam. She will also be given a list of tentative dates for the procedure; the earliest of these will be about three weeks after the physical exam.
The donor goes through a five-day regimen of injections to (a) increase her production of stem cells and (b) force the stem cells out of the marrow and into the bloodstream. On the day of the transplant, the donor will be hooked up to a machine like a dialysis machine: blood will flow out of one arm, through the machine, which will “harvest” the stem cells, and the remaining blood will be put back into the other arm. This is about a 6-8 hour process for the donor. The stem cells will be stored in a bag very much like a regular unit of blood. Since the donor is outside of the US, they will be put on an international flight to Pittsburgh, and transported to the hospital.
By that time, Beth, also, will have undergone an 8-day regimen of intensive chemotherapy and full body radiation. The intention, again, is to destroy all of her damaged bone marrow. The hope is that the new stem cells will “engraft”, or set up shop, within 30 days, and begin to form new bone marrow within Beth’s bones. About that point, Beth will begin to face “rejection” issues — “graft vs host”. Some of this effect is good — the immunity effect of the new “graft” will, it is hoped, destroy any remaining damaged bone marrow and leukemia cells. This is vital, in fact, in preventing relapse. The unfortunate side is that the “graft vs host” also can have side effects that can be very serious, and can even lead to death (i.e., pneumonia and other infections become a very real danger.). And this danger lasts about a year.
Needless to say, Beth is very apprehensive about this. But at least we are moving forward now.
