Tissue brushings and pinch biopsies will also be taken.', 'detailedDescription': 'Tissue injury activates a number of cellular responses to initiate wound healing, resulting in the formation of new tissue within a short span of time and in a controlled fashion. In contrast, cancer results when a tissue mass forms in an unregulated process. Understanding the molecular mechanisms behind appropriate wound healing enables us to delineate how this process goes askew in the context of cancer. The goal is to delineate the mechanisms defining appropriate oesophageal injury and repair, and to use this information to understand how these rules are dysregulated and result in cancer formation.\n\nIn this study, the researchers wish to recruit adult patients undergoing endoluminal vacuum therapy (EVT therapy) for the treatment of perforations to the oesophagus in order to collect the discarded EVT sponge, biopsies from endoscopies, resected surgical specimens and additional blood samples. The researchers will request consent for access to archived tissue samples from any previous related surgery and some associated clinical metadata. The samples and associated clinical metadata will then be pseudonymised and sent to the Wellcome Sanger Institute.\n\nOnce samples are received at the Wellcome Sanger Institute, they will undergo a number of procedures including but not limited to genome sequencing, this will enable the researchers to gain a better understanding of the wound healing process, specifically how it can sometimes go wrong and lead to the development of cancer.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '99 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Adult patients undergoing endoluminal vacuum therapy (EVT) for the treatment of perforations to the oesophagus in order to collect the discarded EVT sponge, biopsies from endoscopies, resected surgical specimens and additional blood samples.', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Male and Female patients 18 years old and over who are having elective upper gastro-intestinal surgery where a leak is a recognised complication (but has not occurred)\n* Male and Female patients 18 years and over who present acutely with an upper gastro-intestinal leak.\n\nExclusion Criteria:\n\n* patients who do not have a good understanding of the English Language'}, 'identificationModule': {'nctId': 'NCT06820151', 'briefTitle': 'Exploring the Landscape of Injury and Repair in the Human Oesophagus', 'organization': {'class': 'OTHER', 'fullName': 'The Wellcome Sanger Institute'}, 'officialTitle': 'Characterising the Genomic and Phenotypic Changes That Define Injury and Repair in the Context of Early Carcinogenesis in the Human Oesophagus.', 'orgStudyIdInfo': {'id': '293952'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Group 1', 'description': 'Group 1 will include patients who are having elective upper gastro-intestinal surgery where a leak is a recognised complication (but has not occurred).', 'interventionNames': ['Other: Sample collection']}, {'label': 'Group 2', 'description': 'Group 2 will include patients who present acutely with an upper gastro-intestinal leak.', 'interventionNames': ['Other: Sample collection']}], 'interventions': [{'name': 'Sample collection', 'type': 'OTHER', 'description': 'Sample collection: EVT sponges, tissue brushings and pinch biopsies', 'armGroupLabels': ['Group 1', 'Group 2']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Cambridge', 'country': 'United Kingdom', 'facility': 'Wellcome Sanger Institute', 'geoPoint': {'lat': 52.2, 'lon': 0.11667}}], 'overallOfficials': [{'name': 'AYESHA NOORANI, PhD MRCS', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Genome Research Limited operating as The Wellcome Sanger Institute'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO', 'description': 'The Wellcome Sanger Institute never shares identifiable information about any of those who participate in its research and has strict measures in place to ensure that the privacy of research participants is protected.'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'The Wellcome Sanger Institute', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
