All patients had CT, PET CT and MR imaging in treatment position prior to radiotherapy.Five experienced observers from our institution will independently delineate GTV on CT alone, MR alone, PET CT alone, on co-registered CT and MR and co-registered PET CT and MR. Inter-observer agreement, expressed in generalized conformity index (CIgen) and mean volumes of GTV will be calculated per patient and imaging modality.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients treated for esophageal cancer with preoperative or curative chemoradiotherapy.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* locally advanced esophageal cancer eligible for treatment with preoperative or curative chemoradiotherapy\n\nExclusion Criteria:\n\n* contraindications for MR'}, 'identificationModule': {'nctId': 'NCT05611658', 'briefTitle': 'Inter-observer Variation in Gross Tumor Delineation of Esophageal Cancer on MR, CT and PET CT', 'organization': {'class': 'OTHER', 'fullName': 'Institute of Oncology Ljubljana'}, 'officialTitle': 'Inter-observer Variation in Gross Tumor Delineation of Esophageal Cancer on MR, CT and PET CT', 'orgStudyIdInfo': {'id': '525'}}, 'armsInterventionsModule': {'interventions': [{'name': 'MR, PET CT', 'type': 'OTHER', 'description': 'diagnostic method'}]}, 'contactsLocationsModule': {'locations': [{'zip': '1000', 'city': 'Ljubljana', 'country': 'Slovenia', 'facility': 'Institute of Oncology', 'geoPoint': {'lat': 46.05108, 'lon': 14.50513}}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Institute of Oncology Ljubljana', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
