Efficiency evaluation | Evaluation criteria |
---|---|
Complete ablation | Disappearance of the lesion |
Complete formation of the cavity | |
Fibrosis of the lesion, which may be a scar | |
Reduction or no change or enlargement of the solid nodule, but no signs of enhancement on enhanced CT scan and/or no metabolic activity of the PET/CT | |
Pulmonary atelectasis, no signs of contrast enhancement on CT scan of the lesion within the atelectasis, and/or no metabolic activity of the PET/CT | |
Incomplete ablation | Incomplete cavity formation with partial solidity and enhanced CT scan with signs of enhancement and/or PET/CT with metabolic activity |
Partial fibrosis with contrast enhancement on CT scan around or at the edge of the fibrosis and/or PET/CT with metabolic activity | |
Solid nodules with no change in size or increase in size with CT scan with signs of contrast enhancement and/or PET/CT with metabolic activity signs of intensification, and/or PET/CT with metabolic activity | |
Tumor cells found on the biopsy | |
Local progression | 10Â mm lesion enlargement with irregular or internal enhancement on CT and significantly increased FDG uptake on PET/CT |
New local lesions with new signs of enhancement on CT and/or significantly increased FDG uptake on PET/CT |
