Shoulder-sparing neck surgery: comparing levels I-III vs I-IV in oral cancer with no neck nodes
Official title: ExteNT N0 Trial- Extent of Neck Treatment in Clinically N0 Oral Cancer: A Randomized Controlled Trial
Run by Kolhapur Cancer Centre - Cancer Centers of America · NCT07726199 · Data updated 2026-11-12
This trial tests whether removing lymph nodes only from levels I-III is as effective as extending to level IV for adults with oral squamous cell carcinoma that has no neck metastasis.

Is this trial a fit for you?
✓Likely a good fit
Adults over 21 with histologically confirmed oral cavity squamous cell carcinoma, clinically node-negative (N0), staged T1-T4, M0, and suitable for curative surgery.
✕Probably not a fit
Patients whose cancer would have responded better to level IV dissection or who have occult disease requiring broader dissection may not see a benefit from limiting to levels I-III.

What this trial studies
This randomized trial compares two selective neck dissection approaches in adults with clinically node-negative oral cavity cancer undergoing curative surgery. Participants are assigned to remove lymph nodes from levels I-III or from levels I-IV to see which method provides similar regional control and survival with potentially less morbidity. Outcomes include regional recurrence-free survival, overall and disease-free survival, and postoperative complications such as shoulder function and quality of life. The study aims to determine if extending surgery to level IV offers any oncologic benefit or just increases morbidity. Eligible patients are adults with histologically confirmed oral cavity squamous cell carcinoma, clinical stage T1-T4, N0, M0, and adequate health status.
Why it matters
Potential benefit: If levels I-III are sufficient, patients may have similar cancer control with fewer complications and better function.
How similar studies have gone: High-quality prospective studies in this area are limited; this trial addresses a gap with randomized design to provide clearer evidence.
