Surgeon-performed ultrasound to guide real-time removal of oral cancer

Official title: Surgeon-performed Ultrasound for Real-time Guidance In Oral Cancer Surgeries - A Multicenter Randomized Controlled Trial

Run by Copenhagen University Hospital, Rigshospitalet · NCT07203911 · Data updated 2026-11-12

This will test whether surgeons using ultrasound during operations can more often remove oral cancers with clear margins in adults with T1–T3 oral squamous cell carcinoma.

Is this trial a fit for you?

Likely a good fit

Adults with biopsy-proven T1–T3 oral squamous cell carcinoma who are scheduled for surgical resection and whose tumor is visible on ultrasound are the ideal candidates.

Probably not a fit

Patients with suspected bone involvement, prior radiotherapy to the oral cavity, tumors not visible on ultrasound, or those unable to consent are unlikely to benefit from the ultrasound-guided approach.

What this trial studies

Participants are randomized at multiple centers to receive standard surgical treatment for oral cancer with or without surgeon-performed intraoperative ultrasound guidance using B-mode imaging in vivo and ex vivo. The intervention is intended to help surgeons distinguish tumor from healthy tissue during resection and to evaluate margins immediately in the operating room. The trial is multicenter (sites in Europe, the USA, and Africa) and is anchored at Rigshospitalet, Copenhagen. Primary and downstream outcomes include frequency of clear surgical margins, need for adjuvant therapy or reoperation, recurrence, mortality, and patient quality of life.

Why it matters

Potential benefit: If successful, using ultrasound during surgery could increase complete tumor removal, reduce the need for additional treatments or repeat operations, and lower recurrence and mortality while improving quality of life.

How similar studies have gone: Smaller diagnostic and single-center studies have shown ultrasound can distinguish tumor from healthy tissue, but multicenter randomized evidence for surgeon-performed intraoperative ultrasound is limited.
