Once the afferent lymphatic channel and sentinel node have been identified, patients undergo cervical lymphadenectomy followed by resection of the primary tumor.\n\nResected primary tumor, radioactive lymph nodes, and blue-stained sentinel nodes are then subjected to molecular (polymerase chain reaction) and histocytochemical (immunohistochemistry for cytokeratin and micrometastases, light microscopy) analyses.\n\nPatients are followed at 1, 3, 6, 12, 18, and 24 months.\n\nPROJECTED ACCRUAL: Approximately 25 patients will be accrued for this study.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'DISEASE CHARACTERISTICS:\n\n* Histologically confirmed primary squamous cell carcinoma of the oral cavity or oropharynx\n\n * Stage 0-IVA (Any T, N0)\n* No low-risk tumors\n* Must require elective staging neck dissection and resection of primary tumor\n\nPATIENT CHARACTERISTICS:\n\nAge:\n\n* 18 to 70\n\nPerformance status:\n\n* Not specified\n\nLife expectancy:\n\n* Not specified\n\nHematopoietic:\n\n* Not specified\n\nHepatic:\n\n* Not specified\n\nRenal:\n\n* Not specified\n\nOther:\n\n* Not pregnant or nursing\n* No concurrent impaired mental status\n\nPRIOR CONCURRENT THERAPY:\n\nBiologic therapy:\n\n* Not specified\n\nChemotherapy:\n\n* No prior chemotherapy\n\nEndocrine therapy:\n\n* Not specified\n\nRadiotherapy:\n\n* No prior radiotherapy\n\nSurgery:\n\n* See Disease Characteristics\n* No prior surgery'}, 'identificationModule': {'nctId': 'NCT00012168', 'briefTitle': 'Lymphoscintigraphy to Detect Early Metastases in Patients With Cancer of the Mouth or Throat', 'organization': {'class': 'OTHER', 'fullName': 'NYU Langone Health'}, 'officialTitle': 'Lymphoscintigraphy Assisted Molecular Staging of Head and Neck Cancer', 'orgStudyIdInfo': {'id': 'CDR0000068489'}, 'secondaryIdInfos': [{'id': 'NYU-9917'}, {'id': 'NCI-G01-1915'}]}, 'armsInterventionsModule': {'interventions': [{'name': 'isosulfan blue', 'type': 'DRUG'}, {'name': 'polymerase chain reaction', 'type': 'GENETIC'}, {'name': 'immunohistochemistry staining method', 'type': 'OTHER'}, {'name': 'lymphangiography', 'type': 'PROCEDURE'}, {'name': 'radionuclide imaging', 'type': 'PROCEDURE'}, {'name': 'sentinel lymph node biopsy', 'type': 'PROCEDURE'}, {'name': 'technetium Tc 99m sulfur colloid', 'type': 'RADIATION'}]}, 'contactsLocationsModule': {'locations': [{'zip': '10016', 'city': 'New York', 'state': 'New York', 'country': 'United States', 'facility': "NYU School of Medicine's Kaplan Comprehensive Cancer Center", 'geoPoint': {'lat': 40.71427, 'lon': -74.00597}}], 'overallOfficials': [{'name': 'Moni A.
