FDG PET parameters differ for predicting advanced colon cancer survival

June 18, 2013

With a host of guidelines for tumor response presented by the now well known Response Evaluation Criteria in Solid Tumors (RECIST) and PET Response Criteria in Solid Tumors (PERCIST), clinicians need to know that not all parameters are alike for predicting patient survival. Case in point, metabolic volume and lesion glycolysis using F-18 FDG PET has been found to be more predictive of survival in patients with metastatic colorectal tumors treated with radioembolization than standardized uptake guidelines, according to a study published May 31 in the Journal of Nuclear Medicine .
