Background: In the present study, PET/CT imaging characteristics were explored to investigate the prognostic value of 18F–fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in oesophageal squamous cell carcinoma (ESCC). Materials and Methods: Baseline PET/CT and clinical characteristics were collected in 125 patients with ESCC treated with radical radiotherapy from 2007–2016. The maximum standardized uptake value (SUVmax) of the primary gross tumour (SUVmax-T) and metastatic lymph nodes (SUVmax-N) were separately measured using X-tile. Overall survival (OS) and progression free survival (PFS) were estimated according to the Kaplan–Meier method. A multivariate Cox model was used to establish the independent prognostic factors. Results: The gross tumours presented higher 18F-FDG uptake than normal tissues. The OS and PFS did not show significant differences between patients with different SUVmax-T values. However, patients with SUVmax-N ≥ 11 had a significantly worse OS and PFS than those with SUVmax-N <11 (P<0.05). A weak correlation was observed in SUVmax-T and SUVmax-N. The OS and PFS of patients with PET-negative lymph nodes (LNs) were significantly better than those with PET-positive LNs. However, the OS and PFS of patients with one or two PET-positive LNs were not significantly better than those with more than two PET-positive LNs. In multivariate analysis, SUVmax-N was suggested to be an independent predictor for OS and PFS. Conclusions: SUVmax-N, but not SUVmax-T, is an independent prognostic indicator for patients with ESCC.
