Table 1 Evaluation of the response to the RAI ablation therapy (Eisenhauer et al., 2009)
Response | Definition | |
|---|---|---|
Non-progressive disease (Non-PD) | Complete response (CR) | Disappearance of all target and nontarget lesions with reduction of lymph node short axis to less than 1 cm and serum Tg undetectable both during suppression and after TSH stimulation |
Partial response (PR) | Decrease of 30% or more in the sum of diameters of target lesions, taking as a reference the baseline sum diameter | |
Stable disease (SD) | Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD or non-PD or non-CR for nontarget disease | |
Progressive disease (PD) | At least a 20% increase in the sum of diameters of target lesions taking as a reference the smallest sum on the study and an increase of at least 5 mm or appearance of one or more new lesions | |
