Stereotactic body radiotherapy (SBRT) for non-small cell lung cancer (NSCLC): Is FDG-PET a predictor of outcome?

Pre-SBRT SUVmax on FDG-PET/CT correlated most strongly with distant failure. A cut off of ⩾5 was the most significant. Post-SBRT SUVmax ⩾2 and a reduction of <2.55 were associated with a higher risk of distant failure.
