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

Objectives: Determine the usefulness of [18F]-fluorodeoxyglucose positron emission tomography/computed tomography ( FDG-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 FDG-PET/CT and CT staging scans in a single referral center. The agreement between FDG-PET/CT, contrast-enhanced CT, and colonoscopy for the surgical location was compared using the κ coefficient.
