Table 2. Definition of target radiological responses.

RECIST 1.1 mRECIST Choi criteria
Complete response(CR) Disappearance of all target lesions Disappearance of any intratumoral arterial enhancement in all target lesions Disappearance of all target lesions
Partial response(PR) At least a 30% decrease in the sum of the greatest unidimensional diameters of target lesions, taking as reference the baseline sum of the diameters of target lesions At least a 30% decrease in the sum of unidimensional diameters of viable (enhancement in the arterial phase) target lesions, taking as reference the baseline sum of the diameters of target lesions Decrease in tumor size ≥10% or decrease in tumor density ≥15% on CT
Stable disease(SD) Any cases that do not qualify for either partial response or progressive disease Any cases that do not qualify for either partial response or progressive disease Does not meet the criteria for CR, PR, or PD
Progressive disease(PD) An increase of at least 20% in the sum of the diameters of target lesions, taking as reference the smallest sum of the diameters of target lesions recorded since treatment started An increase of at least 20% in the sum of the diameters of viable (enhancing) target lesions, taking as reference the smallest sum of the diameters of viable (enhancing) target lesions recorded since treatment started Increase in tumor size ≥10% and does not meet PR criteria by tumor density
