Correlation between TNM staging of primary cholangiocarcinoma and the maximum standard uptake value of (18)F-2-deoxy-D-glucose positron emission tomography with computerized tomography

To investigate the correlation between TNM staging of primary cholangiocarcinoma and the maximum standard uptake value (SUVmax) of (18)F-2-deoxy-D-glucose positron emission tomography with computerized tomography ((18)F-FDG PET/CT). A retrospective analysis of 36 patients with confirmed primary cholangiocarcinoma from October 2014 to July 2016 was carried out. All the patients underwent preoperative PET/CT in the Fifth Affiliated Hospital of Wenzhou Medical University from November 2014 to July 2016, the SUVmax was calculated by drawing region of interest around the primitive tumor area.According to the American Cancer Joint Committee (AJCC) guidelines for the clinical staging of intrahepatic and extrahepatic cholangiocarcinoma, the differences of SUVmax were compared in the patients with different age, gender and staging, and the correlation between TNM staging and SUVmax was determined.Data were compared with independent sample test between groups. The mean SUVmax of 36 patients with primary cholangiocarcin
