Eligibility
Inclusion criteria
Inclusion criteria: 1. Histologically confirmed carcinoma of the esophagus or esophagogastric junction (i.e. tumors involving both cardia and esophagus on endoscopy); 2. Potentially resectable tumor (cT1b-4a N0-3 M0); 3. Undergoing neoadjuvant chemoradiation according to CROSS-regimen; 4. Age >18 years; 5. No history of other cancer or previous radiotherapy or chemotherapy; 6. Signed informed consent.
Exclusion criteria
Exclusion criteria: 1. Patients who meet exclusion criteria for MRI at 1.5T following the protocol of the Radiology department of the UMC Utrecht; 2. Glomerular Filtration Rate (GFR) of <45 mL/min/1.73m2, unless the patient has risk factors for contrast nefropathy according to the UMC Utrecht protocol ‘Preventie contrastreactie en contrast nefropathie, Versie 2 februari 2012’. In patients with risk factors a minimum GFR of 60 mL/min/1.73m2 will be required; 3. Patients with insulin dependent diabetes mellitus or a blood plasma glucose concentration higher than 10 mmol/L; 4. Patients with a known Gadovist allergy; 5. Patients with a known CT-contrast allergy; 6. Patients having difficulty understanding Dutch; 7. Pregnant or breast-feeding patients.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The additional diagnostic value -in terms of accuracy, sensitivity, specificity and predicitve values- of anatomical and functional MRI to PET-CT in the evaluation of treatment response to neoadjuvant chemoradiation therapy for patients with esophageal cancer, as compared to the pathological specimen as gold standard. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Assessment of the optimal (MRI and PET-CT) imaging parameters that correlate best with pathological response; 2. Assessment of the optimal timing for the imaging series; 3. Assessment of the diagnostic value of MRI for post-nCRT restaging of T- and N-stage as compared to histopathology; 4. Assessment of the experienced burden for the patient associated with extra MRI and PET-CT scanning in the clinical work-up for esophageal cancer, as determined by a self-administered questionnaire. | — |
