First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will follow 225 blood cancer patients receiving CAR-T therapy, bispecific antibodies, or high-dose chemotherapy with stem cell transplant. Researchers will test memory, attention, and thinking skills before treatment and up to 3 years after. The goal is to understand how often cognitive problems occur and how they affect quality of life.
