    "body_text": "A retrospective study of patients with advanced non-small cell lung cancer examined FDG-PET scans acquired between 2010 and 2023. Lower brain glucose metabolism was associated with higher one-year mortality and added prognostic information beyond established clinical variables. The marker is an association from historical records, not proof that brain metabolism drives survival or that it should yet change treatment.",
