Survival analysis of PETCAM: A multicenter randomized controlled trial of PET/CT versus no PET/CT for patients with resectable liver colorectal adenocarcinoma metastases.
2012
390 Background: An increasing proportion of patients with liver CAM are undergoing hepatic resection with curative intent. Detection of occult metastastic disease is important in this setting, and PET/CT is used to identify patients with either inoperable, or limited resectable extrahepatic disease not identified with conventional imaging. We recently reported the results related to the primary objective of PETCAM, a randomized trial for patients with resectable liver CAM, where 7.6% had a change in management based on PET/CT (ASCO 2011). As a secondary objective, we examined whether patients undergoing PET/CT derived a survival benefit, as they may be considered to be better selected. Methods: PETCAM was a multicenter trial with 404 subjects randomized 2:1 to receive PET/CT or no PET/CT once they were assessed by a hepatobiliary surgeon to have resectable CAM. Subjects were followed over 4 years for overall survival (OS). As well as the intervention, we considered the SUV, Fong Score and other baseline f...
