First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 92 adults who had chemotherapy for bone tumors (osteosarcoma or Ewing sarcoma) as children or teenagers. Researchers used surveys to measure thinking, memory, and concentration problems years after treatment. The goal was to understand which patients are most at risk for long-term brain side effects, not to test a new treatment.
