Surgeon-performed Intraoperative Transoral Ultrasound for Cancer of Unknown Primary

Denmark30 participantsStarted 2023-02-21

Plain-language summary

Adult patients suspected of Squamous Cell Carcinoma of Unknown Primary (SCCUP) will be prospectively enrolled at a tertiary head \& neck cancer center at Copenhagen University Hospital - Rigshospitalet, Copenhagen, Denmark. All patients will undergo Magnetic Resonance Imaging (MRI) and Positron Emission Tomography-Computerized Tomography (PET-CT) prior to examination in general anesthesia. During general anesthesia, Intraoperative Transoral Ultrasound (ITUS) will be performed prior to panendoscopy. Detected tumors will be registered with specified oropharyngeal sub-locations. Blinded to ITUS, a consultant head \& neck surgeon will perform panendoscopy. After examination, the surgeon is unblinded to ultrasound results. Final histopathology results from location-specified biopsies performed will be used as reference standard. The overall detection rate will be compared between ITUS, panendoscopy, PET-CT and MRI with sensitivity and specificity analysis. Oropharynx sub-location specific detection rate of ITUS vs. panendoscopy will be compared with logistic regression analysis.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Increased detection rate by adding ITUS to panendoscopy

Timeframe: Within 2-4 weeks after panendoscopy.
