Comparing gross examinations and frozen sections for surgical margins in oral cancers

Official title: Intra-operative Gross Examination Versus Frozen Section for Achievement of Adequate Margin in Patients Undergoing Surgery for Oral Cavity Squamous Cell Carcinoma: A Randomized Controlled Trial

Run by Tata Memorial Centre · NCT04809324 · Data updated 2026-11-12

This study is testing whether using frozen section analysis during surgery helps patients with oral cancer have better outcomes compared to just looking at the tissue with the naked eye.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are treatment-naïve adults over 18 years old with biopsy-proven OCSCC planned for curative surgery.

Probably not a fit

Patients with multifocal disease or those who have previously received treatment for oral cavity cancer may not benefit from this study.

What this trial studies

This study evaluates the effectiveness of gross examination versus frozen section analysis for assessing surgical margins in patients with oral cavity squamous cell carcinoma (OCSCC). It aims to determine whether the use of frozen section, which is often employed to ensure adequate margins during surgery, actually improves oncological outcomes compared to gross examination alone. The study will include treatment-naïve patients scheduled for curative surgery and will assess the cost-effectiveness of frozen section procedures in resource-limited settings. The findings could provide insights into the best practices for surgical management of OCSCC.

Why it matters

Potential benefit: If successful, this study could lead to more effective surgical practices and potentially better outcomes for patients with oral cavity cancer.

How similar studies have gone: Previous studies have shown mixed results regarding the effectiveness of frozen section analysis in improving surgical outcomes, indicating that this approach is still under investigation.
