Abstract:
Objective:To explore the value of 18F-FDG PET/CT in preoperative assessment of patients with gallbladder carcinoma.Methods:The clinical data of 59 patients who were preliminarily diagnosed as gallbladder cancer and who accepted PET/CT preoperatively in Zhongshan hospital, Fudan university were retrospectively analyzed.The diagnostic value of PET/CT in the identification of tumor, lymph node metastasis and distant metastasis of gallbladder cancer was statistically analyzed.Results:Of the 59 patients, 55 patients were postoperatively pathologically confirmed as gallbladder cancer, 1 patient as cholangiocarcinoma and 3 patients as inflammatory disease of gallbladder.The sensitivity of PET/CT in tumor identification was 90.9%,while the sensitivity and specificity of PET/CT in the diagnosis of lymph node metastasis and distant metastasis were 61.5% and 72.3%, 66.7% and 91.1%, respectively.SUVmax value showed no statistical difference in tumor staging, lymph node metastasis and distant metastasis.Conclusions:PET/CT is of important value in the preoperative evaluation of gallbladder cancer, especially in the assessment of lymph node metastasis and distant metastasis.However, its value in tumor staging remains to be further evaluated.
