Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Observational study to analyse esophageal tumor regression and tumor movement during nCRT in order to develop adaptive radiotherapy planning strategies using intratreatment delineations of MR images to improve target coverage and critical organ sparing. | — |
Secondary
| Measure | Time frame |
|---|---|
| Only applicable to patients with resectable esophageal cancer: Besides the primary endpoint anatomical and functional MR images will be used to further assess and evaluate the optimal time of scanning during nCRT to predict pathological response to treatment with pathology of the resected specimen as reference standard. Furthermore, the value of 'dynamic contrast-enhanced MRI' for early response assessment during nCRT will be assessed. | — |
