Although ILR carries significant promise in prevention of lymphedema, there is a lack of high-level evidence supporting its efficacy because it is a novel surgical technique that is only offered at a few centers and not routinely covered by insurance carriers yet. The University of Chicago Comprehensive Cancer Center (UCCCC) is one of the busiest microsurgery centers performing this procedure, and, as a Lymphedema Center of Excellence, is in a unique position to investigate the efficacy of ILR in preventing lymphedema. In addition, the University has access to a world class microbiome research facility and colleagues. To our knowledge, there is no information on the skin microbiome of the axilla in patients undergoing treatment for breast cancer or those at risk for developing lymphedema. Further exploratory studies such as this in a diverse patient population may lead to practice changing research in our approach to lymphedema management and prevention.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'patients who are potential candidates for ILR based on possible nodal involvement assessed preoperatively.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\npotential candidates for ILR based on possible nodal involvement assessed preoperatively.\n\nExclusion Criteria:\n\n* Individuals who are not eligible for ILR based on possible nodal involvement assessed preoperatively.'}, 'identificationModule': {'nctId': 'NCT07227467', 'briefTitle': 'Prospective Assessments Following Immediate Lymphatic Reconstruction', 'organization': {'class': 'OTHER', 'fullName': 'University of Chicago'}, 'officialTitle': 'Prospective Assessments Following Immediate Lymphatic Reconstruction', 'orgStudyIdInfo': {'id': 'IRB25-1329'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'patients who are potential candidates for immediate lymphatic reconstruction (ILR)', 'description': 'potential candidates for ILR based on possible nodal involvement assessed preoperatively.', 'interventionNames': ['Other: patients who are candidates for immediate lymphatic reconstruction']}], 'interventions': [{'name': 'patients who are candidates for immediate lymphatic reconstruction', 'type': 'OTHER', 'description': 'potential candidates for ILR based on possible nodal involvement assessed preoperatively.', 'armGroupLabels': ['patients who are potential candidates for immediate lymphatic reconstruction (ILR)']}]}, 'contactsLocationsModule': {'locations': [{'zip': '60637', 'city': 'Chicago', 'state': 'Illinois', 'status': 'RECRUITING', 'country': 'United States', 'contacts': [{'name': 'Summer Hanson, MD, PhD, FACS', 'role': 'CONTACT', 'email': 'sehanson@bsd.uchicago.edu', 'phone': '(773) 702-6302'}], 'facility': 'The University o Chicago', 'geoPoint': {'lat': 41.85003, 'lon': -87.65005}}], 'centralContacts': [{'name': 'Summer Hanson, MD, PhD, FACS', 'role': 'CONTACT', 'email': 'sehanson@bsd.uchicago.edu', 'phone': '(773) 702-6302'}], 'overallOfficials': [{'name': 'Summer Hanson, MD, PhD, FACS', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University of Chicago'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Chicago', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
