A Brain Scan Signal Shadows Lung-Cancer Survival
Lower cerebral glucose metabolism on existing PET scans was associated with higher one-year mortality in advanced disease.
Summary
Lower cerebral glucose metabolism on existing PET scans was associated with higher one-year mortality in advanced disease.
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.
Why it matters
Lower cerebral glucose metabolism on existing PET scans was associated with higher one-year mortality in advanced disease.
Limits and context
- The marker is an association from historical records, not proof that brain metabolism drives survival or that it should yet change treatment.
Key claims
