Table 1 Therapeutic response criteria

From: Role of multislice computed tomography 3D volumetric analysis in the assessment of the therapeutic response of hepatocellular carcinoma after transarterial chemoembolization

Response RECIST for HCC mRECIST for HCC vRECIST for HCC
Complete response (CR) Disappearance of all target lesions Disappearance of any intra-tumoural arterial enhancement in all target lesions Disappearance of any intra-tumoural arterial enhancement in all target lesions
Partial response (PR) At least 30% decrease in the diameter of the whole lesion At least 30% decrease in the diameter of viable component measured in the arterial phase of the study At least 65% decrease in the volume of the enhancing component measured in the arterial phase of the study
Stable disease (SD) Cases not fulfilling the criteria of partial response or progressive disease
Progressive disease (PD) Increase the diameters of target lesion by at least 20% Increase the diameters of the enhancing component only by at least 20% Increase of at least 20% in the volume of the viable (enhancing) component of the target lesions
