I re-read all your posts just to make sure I didn't miss anything. Nate's journey has been an unusual one with a rocky start, odd symptoms, secondary health problems, and questions over his CML Phase. Theseare the main reasons why the Onc wants to do the transplant. Plus Nate has a hard time staying on a drug (very low platelets) long enough to respond well.
But Nate's FISH reached 25% at one point, so he CAN RESPOND to the drugs (sorry for shouting -- a little joke there). And his blood counts normalized, but went too low. So there is still enough reason to believe that if he can stay on a drug, that he might respond well enough longer term. So is a BMT necessary, given the risks? I do not know, and neither does anyone else. It is a decision, not an algorithm with lots of known numbers and facts.
Regarding the transplant issue, it is not an easy answer. Oncs like BMTs in unusual cases since they do not know what lies ahead for Nate. But if an Onc had this choice for his own child, I wonder what he would do. Just wondering out loud. But offering a transplant means nothing if you do not have a very good match already identified. Nate's siblings are not a match, so he would need to find an unrelated donor. To me, I could never say yes or no to a BMT unless I saw the matches that were offered. But the Onc seems to want a commitment first, and then a matching process. I would say "show me the matching options, then I will decide".
For me personally, if I were in Nate's situation, I would likely resist the BMT since there is adequate response to the drugs, and reasonable hope that he can remain on one of them, although it may require transfusions. The other issue is that Nate's overall health may not be strong enough right now for a BMT. He has been having heart related issues (unknown cause) and has possible damage from the 600K WBC that caused oxygen deprivation to his organs. So overall, the Onc may think that a BMT is needed, but Oncs think a BMT is just another treatment option. To me it is a last resort. That is how I look at it.
