It will also evaluate whether extending the neck dissection to level IV affects cancer control, surgical complications, shoulder function, and quality of life. The main questions it aims to answer are:\n\n* Does selective neck dissection of levels I-III provide regional recurrence-free survival comparable to selective neck dissection of levels I-IV?\n* Does extending the neck dissection to level IV improve overall survival, disease-free survival, or reduce regional recurrence?\n* Does selective neck dissection of levels I-III result in less postoperative morbidity, better shoulder function, and improved quality of life compared with selective neck dissection of levels I-IV?\n\nResearchers will compare patients undergoing selective neck dissection of levels I-III with those undergoing selective neck dissection of levels I-IV to determine whether routine removal of level IV lymph nodes provides additional oncological benefit while maintaining acceptable functional outcomes.\n\nParticipants will:\n\n* Undergo surgery for oral squamous cell carcinoma with random assignment to selective neck dissection of either levels I-III or levels I-IV.\n* Receive standard postoperative treatment, including radiotherapy or chemoradiotherapy when indicated according to the final pathology report.\n* Attend scheduled follow-up visits for clinical examinations and surveillance for cancer recurrence.\n* Undergo assessments of shoulder function, sensory function, postoperative complications, and quality of life using validated questionnaires at predefined follow-up intervals.",[28],"Oral Squamous Cell Carcinoma (OSCC)",[30,31,32,33,34,35,36,37],"Oral Squamous Cell Carcinoma","Oral Cancer","cN0","Selective Neck Dissection","Occult Nodal Metastasis","Regional Recurrence","Head and Neck Cancer","Randomized Controlled Trial","RECRUITING","2026-08-01",{"date":41,"type":42},"2026-08-04","ACTUAL",{"date":44,"type":42},"2026-04-22",{"date":46,"type":22},"2030-09-01",{"name":48,"class":49},"Kolhapur Cancer Centre - Cancer Centers of America","OTHER",1,{"id":52,"slug":53,"hasResults":11,"nctId":54,"briefTitle":55,"officialTitle":56,"acronym":57,"eligibilityCriteria":58,"healthyVolunteers":11,"sex":17,"minAge":18,"maxAge":19,"enrollmentInfo":59,"targetDuration":4,"studyType":23,"phases":61,"briefSummary":62,"conditions":63,"keywords":65,"overallStatus":38,"whyStopped":4,"lastUpdateSubmitDate":39,"lastUpdatePostDateStruct":69,"startDateStruct":70,"completionDateStruct":71,"leadSponsor":73,"locationsCount":50},"100648068","study-comparing-limited-and-extensive-neck-surgery-in-oral-cancer-patients-with-neck-spread-100648068","NCT07717307","Study Comparing Limited and Extensive Neck Surgery in Oral Cancer Patients With Neck Spread","Extent of Neck Treatment in Clinically N1 Oral Cancer: A Randomized Controlled Trial","ExtentN1","Inclusion Criteria:\n\n* Histologically proven squamous cell carcinoma of oral cavity will be included\n* Clinical stage T1-T4, N1, M0\n* cN1 neck on clinical examination and imaging (CT\u002FMRI)\n* Single node which is FNAC proven without any other significant nodes.\n* Patients with ASA grade II and I.\n* Understands the protocol and able to give informed consent.\n\nExclusion Criteria:\n\n* Recurrent cases\n* Multiple significant nodes\n* Nodes clinical\u002Fradiological with ENE\n* Single metastatic node at level III\u002FIV\u002FV\n* Single metastatic node with other suspicious nodes\n* Patients with a history of head and neck radiation therapy treatment\n* Previous history of any malignancy",{"count":60,"type":22},80,[25],"Oral cavity squamous cell carcinoma (OCSCC) frequently metastasizes to cervical lymph nodes, and the extent of neck dissection remains an area of ongoing debate in patients with clinically node-positive (cN1) disease. While modified neck dissection (MND, levels I-V) is widely practiced, selective neck dissection (SND, levels I-IV) may provide equivalent oncologic outcomes with reduced surgical morbidity. However, high-quality randomized evidence comparing these approaches is lacking.\n\nThe ExteNT N1 Trial is a prospective, randomized, open-label, parallel-group clinical trial designed to compare selective neck dissection (levels I-IV) with modified neck dissection (levels I-V, preserving the spinal accessory nerve, internal jugular vein, and sternocleidomastoid muscle) in patients with resectable cN1 oral cavity squamous cell carcinoma. Eligible participants will be randomized in a 1:1 ratio to either treatment arm.\n\nThe primary endpoint is 3-year regional recurrence-free survival (RRFS), along with postoperative quality of life measured using the Neck Dissection Impairment Index (NDII). Secondary endpoints include overall survival, disease-free survival, level-wise nodal involvement, nodal yield, shoulder function (Constant-Murley Score, SPADI, and Arm Abduction Score), postoperative complications including chyle leak, and other surgical morbidities.\n\nThis trial aims to generate level I evidence regarding the optimal extent of neck dissection for cN1 OCSCC, balancing oncologic safety with preservation of postoperative function and quality of life.",[64],"Oral Cavity Squamous Cell Carcinoma",[64,31,36,66,67,68],"Neck Dissection","Modified Neck Dissection","Cervical Lymph Node Metastasis",{"date":41,"type":42},{"date":39,"type":42},{"date":72,"type":22},"2031-04-23",{"name":48,"class":49},""]
