The samples will be imaged using the LightPathTM Imaging System. The LightPathTM Imaging System which consists of a light-tight box on which are mounted an ultra-sensitive lens and radiation-shielded camera. This study will measure the correlation between margin status of the WLE specimen and the metastatic status of dissected lymph nodes as determined by the LightPathTM Imaging System and by histopathology. This is a pilot study to assess feasibility before proceeding to a pivotal study to evaluate the benefits of the LightPathTM Imaging System in clinical practice.', 'detailedDescription': "Subject's blood glucose level will be measured on the day of surgery. Subjects with a blood glucose level \\< 12 mmol/l receive an intravenous injection of 5 MBq/kg, up to a maximum 300 MBq of 18F-fluorodeoxyglucose (18F-FDG) prior to surgery. Breast cancer surgery will be performed per standard of care. SLNB will be performed using a dose of 150 MBq technetium 99 (99mTc) nanocolloid and patent blue dye. The resected WLE specimen and lymph nodes will be imaged in the LightPathTM Imaging System. A member of the research team who is not the operating surgeon will capture LightPathTM images intra-operatively.\n\nPrior to CLI, the WLE specimen will be placed in a specimen holder. CLI is performed according to the LightPathTM Imaging System instructions for use. All CLI will be performed between 1 and 3 hours post injection of 18F-FDG.\n\nThe WLE specimen will then undergo standard of care histopathological analysis with a positive margin defined as either invasive carcinoma or ductal carcinoma in situ (DCIS) within 2mm of the specimen surface. Lymph nodes will also be examined according to standard of care histopathological analysis.\n\nThe CLI results will not be used to influence any surgical or clinical decision-making.\n\nAll staff in the operating theatre and the recovery area caring for the patient, and pathology staff processing surgical specimens will wear badge dosimeters. Staff handling surgical specimens will also wear ring dosimeters."}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '30 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Female patients ≥30 years of age with known breast cancer scheduled for breast-conserving surgery (BCS) +/- sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND)', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria\n\n* Females ≥30 years of age with a diagnosis of invasive breast cancer or DCIS\n* Scheduled for BCS +/- SLNB or ALND\n* Females of childbearing age must have a negative pregnancy test (by Beta HCG qualitative analysis), must have had a history of a surgical sterilisation, or must give history of no menses in past twelve months\n\nExclusion Criteria\n\n* Surgery or radiotherapy in the operated breast in the past 2 years\n* Neoadjuvant systemic therapy\n* Patients not suitable for BCS\n* Blood glucose level ≥ 12 mmol/l on the day of surgery\n* Known hypersensitivity to 18F-FDG\n* Any patient who is pregnant or lactating'}, 'identificationModule': {'nctId': 'NCT02037269', 'briefTitle': 'LightPathTM Imaging System for Ex-vivo Assessment of Margin and Lymph Node Status in Breast Cancer Surgical Specimens', 'organization': {'class': 'INDUSTRY', 'fullName': 'Lightpoint Medical Limited'}, 'officialTitle': 'A Pilot Study to Evaluate Cerenkov Luminescence Imaging for Measuring Margin and Lymph Node Status in Breast Cancer Surgical Specimens', 'orgStudyIdInfo': {'id': 'LPM-001'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'All participants', 'description': 'Female patients ≥30 years of age with known breast cancer scheduled for breast-conserving surgery (BCS) +/- sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND)'}]}, 'contactsLocationsModule': {'locations': [{'zip': 'SE1 9RT', 'city': 'London', 'country': 'United Kingdom', 'facility': "Guy's Hospital", 'geoPoint': {'lat': 51.50853, 'lon': -0.12574}}], 'overallOfficials': [{'name': 'Anand D Purushotham, MBBS FRCS MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': "King's College London"}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Lightpoint Medical Limited', 'class': 'INDUSTRY'}, 'collaborators': [{'name': "Guy's and St Thomas' NHS Foundation Trust", 'class': 'OTHER'}, {'name': "King's College London", 'class': 'OTHER'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
