Comparing two surgical approaches for early mouth cancers

Official title: Sentinel Node Biopsy Versus Limited Elective Neck Dissection in Early Cancers of Oral Cavity NoDe Negative (SECOND N0): Non-inferiority Phase III Trial

Run by Tata Memorial Hospital · NCT05774483 · Data updated 2026-11-12

This study is testing whether a less invasive surgery for early mouth cancers can provide similar survival rates while being easier on patients and more affordable than the standard approach.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults over 18 with biopsy-proven invasive squamous cell carcinoma of the tongue or buccal mucosa that is clinically node-negative.

Probably not a fit

Patients with previous head and neck surgeries, other malignancies, or those requiring complex reconstructive procedures may not benefit from this study.

What this trial studies

This clinical trial aims to compare the survival outcomes, morbidity, and cost-effectiveness of sentinel node biopsy (SNB) versus limited elective neck dissection (END) in patients with early, node-negative oral cancers. Participants will be randomly assigned to either undergo SNB, which may involve a second procedure if metastasis is detected, or limited END, which selectively clears lymph nodes based on metastatic findings. The study seeks to determine if limited END can provide similar survival outcomes with reduced morbidity and better cost-effectiveness compared to SNB.

Why it matters

Potential benefit: If successful, this study could provide a less invasive and more cost-effective surgical option for patients with early oral cancers.

How similar studies have gone: Previous studies have shown promising results for sentinel node biopsy in similar contexts, but this comparison with limited elective neck dissection is relatively novel.
