Early metabolic response evaluation may predict clinical and histopathological response after neoadjuvant chemotherapy. Its value in neoadjuvant chemoradiotherapy (CRT) is unknown. Our aim was to assess the value of early metabolic response after one cycle of chemotherapy using 18-FDG-PET-CT to predict pathological response and outcome in cT2-4 N0/+ esophageal cancer treated by neoadjuvant CRT and esophagectomy.

Condition Intervention
Esophageal Carcinoma (Squamous Cell Carcinoma - Adenocarcinoma) Other: 18-FDG-PET-CT

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Early Metabolic Response Evaluation With 18-FDG PET-CT in Esophageal Cancer Treated With Neoadjuvant Chemoradiotherapy Followed by Esophagectomy

Further study details as provided by Universitaire Ziekenhuizen Leuven:

Primary Outcome Measures:
  • early metabolic response to predict pathological response and outcome
    assess the value of early metabolic response with 18-FDG-PET-CT (i.e. a decrease of ≥ 35% of SUVmean) after a single cycle of chemotherapy followed by neoadjuvant CRT and esophagectomy as a tool to predict pathological response and outcome in patients with cT2-4N0/+ carcinoma of the esophagus and GE-junction (GEJ).

Secondary Outcome Measures:
  • to study correlations between early metabolic response, late metabolic response, histopathological response and outcome.
