    Abstract:
    PURPOSE: This study aimed to determine the pathological complete response (pCR), overall survival (OS), and disease-free survival (DFS) in patients with locally advanced esophageal squamous cell carcinoma (ESCC) using post-neoadjuvant chemoradiotherapy (nCRT) F-18-fluorodeoxyglucose (18FDG). METHODS: This is a retrospective study of patients with locally advanced ESCC receiving nCRT and then esophagectomy between January 2011 and December 2018 in the Tri-Service General Hospital, Taipei, Taiwan. A total of 50 patients were enrolled in the study. Survival analysis was performed using the Kaplan-Meier method and Cox proportional hazards model. Univariate and multivariate analysis were used to determine the independent prognostic factors. RESULTS: Fifty patients were enrolled in the study, and 18 had pathological complete response. Post-nCRT SUVmax ≥ 3 is a poor prognostic factor associated with overall survival (HR: 3.665, P = 0.013) and disease-free survival (HR: 3.417, P = 0.011). Poor prognosis was found in the non-pCR plus post-nCRT SUVmax ≥ 3 group compared with pCR plus post-nCRT SUVmax < 3 group. CONCLUSIONS: SUVmax ≥ 3 is a poor prognostic factor in esophageal squamous cell carcinoma after trimodality treatment, even in patients having pathological complete response.
