Table 6 Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST)

From: Imaging biomarkers for evaluating tumor response: RECIST and beyond

Response Criteria
CR • Disappearance of all metabolically active tumor
PR • > 30 % decrease in SUL peak (minimum 0.8 unit decrease) in lesion with greatest uptake (not necessarily the same lesion)
PD • > 30 % increase in SUL peak (minimum 0.8 unit increase)
• > 75 % increase in total lesion glycolysis
• New lesions
SD • Does not meet above criteria
  1. CR complete metabolic response, PD progressive metabolic disease, PR partial metabolic response, SD stable metabolic disease, SUL standardized uptake value using lean body mass
