Tests from BJ's bone marrow biopsy are back, and they saw lots of blast cells in his marrow. We knew this would be the case, because there were some blast cells in his peripheral blood on Friday.
They are still running tests to determine the percentage of blasts in the marrow. Initially, they saw no white blood cells in his spinal (CSF) fluid from the LP yesterday...this is great news.
We'll know tomorrow if there are blast cells in his CSF.
Because he relapsed while he was still in treatment from his initial diagnosis, he is considered high risk, and an early relapse, and will need a bone marrow transplant.
Leading up to the transplant, he will undergo high doses of chemo to wipe out his marrow.
The goal is to have no leukemia cells left in his marrow leading up to the transplant.
