Biomarkers and Imaging analysis
This study will prospectively collect the tissue and blood samples of locally advanced esophageal cancer patients, perform CRT resistance biomarkers testing and functional imaging analysis including SUV value and texture parameters of 18F-FDG PET-CT as well as ADC values DWI-MRI before treatment, 2-3 weeks after the initiation of CRT, and 4 weeks post-nCRT. The investigators will use advanced statistical tools to establish the model and further validate the model in another group of patients. The investigators will also establish a model for survival prediction.
Other: Biomarkers Testing
CRT resistance biomarkers will be detected before CRT, 2-3 weeks after the initiation of CRT, and 4 weeks post-CRT.
Other: Functional Imaging analysis
The SUV value and texture parameters of 18F-FDG PET-CT as well as ADC values DWI-MRI will be measures before CRT, 2-3 weeks after the initiation of CRT, and 4 weeks post-CRT.
- Pathologic Response [ Time Frame: Approximately 12 months ]Mandard tumor regression grade (TRG) was used for pathology analysis. Primary tumor and positive lymph node regression were classified into five histologic tumor regression grades. Grade 1 (complete regression) showed absence of histologically identifiable residual cancer and fibrosis extending through the different layers of the esophageal wall, with or without granuloma. Grade 2 was characterized by the presence of rare residual cancer cells scattered through the fibrosis. Grade 3 involved an increase in the number of residual cancer cells, but fibrosis still predominated. Grade 4 showed residual cancer outgrowing fibrosis. Grade 5 was characterized by the absence of regressive changes.
- Overall Survival [ Time Frame: Approximately 4 years ]
