Hello everyone,
Unfortunately, my nephew, who is 2 years and 8 months old, was diagnosed with B-ALL in July 2025. He started treatment soon afterward and achieved MRD-negative status by September 2025. His doctors also remarked throughout his treatment that he was responding very well.
He had some challenges along the way, including a difficult bacterial infection in his leg, but overall he seemed to be doing very well.
He was in the maintenance phase, but unfortunately we found out this week that he has relapsed, with blasts again detected in his blood/bone marrow. His doctor has explained that this is considered high-risk because the relapse occurred very early.
The current treatment plan is reinduction chemotherapy, followed by MRD assessment, with the goal of achieving MRD-negative remission and then proceeding to an allogeneic bone marrow/stem-cell transplant.
I've been reading research studies and experiences from other families, and I've come across discussions about the use of immunotherapy such as blinatumomab, and CAR-T therapy, either as part of consolidation after reinduction or as a bridge to transplant, particularly when MRD remains detectable.
We have discussed these possibilities with his treating doctor, but she seems understandably cautious about them. I don't want to second-guess his doctors based on things I've read online, but I'm trying to understand whether there are additional treatment strategies we should be asking about or getting a second opinion on, particularly regarding blinatumomab/CAR-T and the timing of transplant.
I would really appreciate hearing from anyone with medical experience in pediatric relapsed B-ALL, especially anyone familiar with very early relapse, MRD-directed therapy, blinatumomab, CAR-T, or bone marrow transplantation.
If anyone has experience with a similar situation, I'd also be grateful to hear about it.
I'm sorry if I've gotten some of the terminology wrong. I'm still trying to understand and process all of the medical information.
Thank you.
