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 |
