I think this sums it up (from the NIH study):

My daughter recovered from Leukemia (ALL). She's healthy now, but it was a nightmare. She was in the "high risk" category until the doctors realized the chemo triggered a rare kidney disorder. Once that was treated, the chemo started to work.
I've observed some issues with her memory and cognition, but I'm happy she's alive and optimistic that she'll learn to work around the challenges.
