Preoperative Staging of Cholangiocarcinoma and Biliary Carcinoma using 18F-Fluorodeoxyglucose Positron Emission Tomography: A Meta-Analysis

This meta-analysis was performed to determine the diagnostic accuracy of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) in assessing primary cholangiocarcinoma (CCA) and CCA with lymph node and distant metastasis. A literature search for studies reporting the use of 18F-FDG-PET for preoperative work-up/staging in patients with CCA was performed. Diagnostic OR (DOR) was used as an index of diagnostic performance of FDG-PET/CT...
