Objectives: To assess the value of 18FDG PET/CT in stage diagnosis in esophageal cancer patients. Subjects and methods: 32 esophageal cancer patients were performed 18FDG PET/CT for initial stage diagnosis before the treatment. Results: 18FDG uptake of osephageal tumors increased, SUVmax increase from 3.1 to 44.8; average value 17.9 ± 9.2; It increased with invasive degree and stage of tumor. The 18FDG PET/CT changed diagnosis of T stage in 2/32 patients (6.3%), of N stage in 15/32 patients (46.8%), detected metastases in 14 patients. After using 18FDG PET/CT, 14/32 patients (43.7%) were upstaged, which included 7/10 patients (70%) of stage I and II and 7/15 patients (46.7%) of stage III. Conclusion: 18FDG PET/CT scan effectively detected nodes, distant metastases, it had great value in stage diagnosis of esophageal cancer patients. * Keywords: Esophageal cancer; Staging diagnosis; 18FDG PET/CT.
