Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It is very significant that assessing TN staging in esophageal cancer patients before surgery, furthermore, determining the optimize surgical strategy, predict the the efficacy of radiotherapy for patients who were not chosen to be surgeried, and define the range of lymph node for radiotherapy. It has been reported that the application of MRI in metastasis of lymph node of other cancer, but not in metastasis lymph node with esophageal cancer. Only a few studies focused on T staging using conventional MRI in esophageal cancer, however, relatively new sequences in the chest deserve widely used. To develop a pre-treatment evaluation methods for TN staging in patient with esophageal cancer by utilization of the new imaging methods (T2-TSE-BLADE, T2 maps, StarVIBE). By analysising the relationship between TN staging and imaging features to find the imaging characteristics for TN staging, and to find the indicators of magnetic resonance imaging new technology and reference values for facilitate pre-treatment diagnosis of lymphnode metastasis, optimize surgical strategy, predict the the efficacy of adjunctive therapy, and OS and define the range of lymph node for radiotherapy, as making personal treatment planning for esophageal cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To explore the value of 3 T MRI using multiple sequences, including T2-TSE-BLADE, T2 maps and StarVIBE, in evaluating the preoperative TN staging and prediction of response to neoadjuvant therapy and OS in patients with esophageal cancer.

Patients with endoscopically biopsy-proven EC were prospectively enrolled for imaging on a 3 T scanner. The MRI protocol included T2-TSE-BLADE, T2 maps and StarVIBE sequences, and so on. Patients received treatment according to NCCN guideline. Readers assigned a TN stage on MRI, and post-operative pathologic confirmation was considered the gold standard. Inter-reader agreement, the diagnostic accuracy of TN staging on MRI were analyzed and compared to post-operative pathologic TN staging. MRI features were analyzed to find the correlation between pretreatment MRI features and response or OS. The study will includ 400 patients. Inter-reader agreements of TN staging were analyzed excellent for MRI. Diagnostic accuracy of MRI will be calculated.
