What this study is about

This trial is testing a new treatment called B7-H3-CAR T cells, combined with radiation therapy and chemotherapy, to see if it's safe for children with certain types of cancer. The goal is to determine the safety of this combination approach in young people whose cancers have returned after other treatments.
