We found out the preliminary results of the bone marrow matching today. We didn't originally realize that further tests would be required after these results in order to find the best match, but preliminarily the news was unexpectedly good.
Spencer has four siblings and based on these first tests, three of them are perfect matches (thus far in the process). The hospital said to have that many matches, even in this first step, is so unheard of that they double checked the results just to make sure.
Even while they were gushing about how they'd never seen that many matches before, they were also quick to tell us not to be too relieved yet, since more extensive (and expensive) testing still needs to be done.
We'll take what we can get.
Random Facts about Bone Marrow Transplants
The preliminary bone marrow matching tests 6 HLA markers in the blood. The remaining 4 markers are much more expensive to test for, so they do the preliminary testing to weed out the number that move on to further testing. All three girls will go onto the further testing. The most successful transplants have 10 out of 10 matches.
If an in-family perfect match is found, then round 4 of Spencer's chemo will be performed at Children's Hospital in Washington, DC. The chemo will be very intense and will basically destroy his immune system in its entirety before the transplant. The whole process is expected to take about 2 months in the hospital and another 2-4 months of recovery.
Bone marrow transplants are risky, but also give the greatest chance for a complete cure. Having an in-family match maximizes the chances for success.
A bone marrow donor can have a different type of blood than the recipient. In this case, after the transplant is done the recipient often changes blood types to match the donor.
The bone marrow recipient will also often develop similar allergies as the donor, since basically their immune systems will be the same afterward.
