Table 1 Assessment of target lesion response

mRECIST		RECIST		Subjective percentage of necrosis
CR	Disappearance of any intratumoral enhancement in all target lesions	CR	Disappearance of all target lesions	CR	Disappearance of any intratumoral enhancement in all target lesions
PR	At least a 30% decrease in the sum of diameters of viable target lesions	PR	At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of the diameters of target lesions	PR	At least a 30% increase in the sum of target lesion necrosis percentages
SD	Any cases that do not qualify for either partial response or progressive disease	SD	Any cases that do not qualify for either partial response or progressive disease	SD	Any cases that do not qualify for either partial response or progressive disease
PD	An increase of at least 20% in the sum of the diameters of viable target lesions or new lesion appearance	PD	An increase of at least 20% in the sum of the diameters of target lesions or new lesion appearance	PD	A decrease of at least 20% in the sum of target lesion necrosis percentages or new lesion appearance

mRECIST: Modified response evaluation criteria in solid tumors; CR: Complete response; PR: Partial response; SD: Stable disease; PD: Progressive disease.
