| Complete metabolic remission |
Total loss of measurable lesion 18F-FDG uptake to below average liver radioactivity and indistinguishable from the surrounding blood pool background |
| Partial metabolic remission |
Reduction of 18F-FDG uptake in the target lesion by ≥30 and an absolute reduction of ≥0.8 |
| Metabolic stabilization of disease |
Non-complete metabolic remission, partial metabolic remission, disease metabolic progression |
| Disease metabolic progression |
Increased 18F-FDG uptake in target lesions ≥30 with an absolute increase of ≥0.8; or new lesions |
Note: It is recommended to use lean weight-corrected standard uptake values to reduce the impact of patient weight changes on parameters during treatment
