@dwolden thanks for the good wishes. He had a stem cell transplant (his own cells) almost 10 years ago for Multiple Myeloma, which went fairly smoothly and got the Myeloma under control. The Leukemia is a result of one of the chemo drugs he was taking to keep the Myeloma in remission, which it is. So far the Car-T is going well so far, and we have good hopes for it. The docs want to do a BMT just a few months after the Car-T. Sigh, that does seem like a lot for him to handle, but thankfully he's basically in good shape, so we'll see. I was kind of hoping we could see how the Car-T does a bit longer term. This cancer thing is quite the roller coaster ride! It's great to have this community to put things into perspective.
