Impact of routine preoperative 18FDG PET/CT on the surgical management of primary colorectal cancer

Objectives Determine the usefulness of [18F]‐fluorodeoxyglucose positron emission tomography/computed tomography (18FDG‐PET/CT) in the preoperative setting of colorectal cancer (CRC), assessing its impact on changes in management strategy. Methods Retrospective study of CRC patients who underwent preoperative 18FDG‐PET/CT and CT staging scans in a single referral center. The agreement between 18FDG‐PET/CT, contrast‐enhanced CT, and colonoscopy for the surgical location was compared using the κ coefficient. Maximum standardized uptake (SUVmax) value was obtained. Univariate and multivariate analyses were conducted. Results One hundred ninety‐five patients were included. 18FDG‐PET/CT improved tumor localization in 84.6% (165/195) of cases (κ value 0.798, p
