About this study

Official title: Feasibility of Surface Optical Guidance to Replace the Restraint Mask for External Radiotherapy of Head and Neck Cancer

The goal of this clinical trial is to test the use of surface repositioning alone, without a restraint mask, during radiotherapy sessions for patients with head and neck cancer.

Read the detailed description

In radiotherapy treatments for head and neck cancer, the use of a mask is recommended for patient immobilization. The mask completely covers the head and shoulders, ensuring reproducible positioning at every session. However, using a mask can be oppressive and anxiety-provoking for patients.

At the same time, technological developments have led us to use optical surface camera systems to position and monitor patients in the treatment room. In this way, if a movement exceeding the threshold is detected during a session, the treatment is automatically interrupted.

However, despite the use of the mask, movements are still possible underneath, and are not detected by the surface cameras.

The study's hypothesis is that the use of surface repositioning alone could guarantee reproducible treatment, as in combination with a thermoformed mask. In addition, eliminating the mask would mean greater comfort and improved quality of life for patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Surface Guided RadioTherapy (SGRT) without maskProcedure or surgery

    Firstly, patients are positioned in a vacuum mattress that moulds their head, neck and shoulders for a reference scan.

    During the treatment sessions, patients are positioned according to the reference scan, using the surface camera system.

    Once the observed offsets have been applied, the patient's surface is captured. Treatment can then begin, with continuous monitoring of displacements by the surface camera system. Automatic beam interruption is provided during treatment in the event of motion detection exceeding the standard tolerance threshold (>3 mm).

    If the use of a thermoformed mask during your treatment prove necessary, for whatever reason, will not result in a halt to the research.

    Patients receive between 10 and a max of 35 radiotherapy sessions. The follow-up period begins after the last radiotherapy session, and patients are assessed at 4 or 6 weeks and at 3 months by a radiotherapist.

Study groups in NCT06627075
Study groupRoleWhat they receive
Surface Guided RadioTherapy without face maskExperimentalRadiotherapy sessions will be carried out using the surface camera system, replacing the restraint mask. Self-assessment questionnaires will also be completed by healthcare professionals concerning the level of difficulty encountered during each SGRT session without mask. Skin side effects are recorded by the radiotherapist during weekly follow-up consultations. At the end of treatment, patients complete a patient experience questionnaire.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Measurement patient displacement during surface-guided radiotherapy sessions

    Average length of linear translation vector during session (measured by surface cameras) over all sessions performed

    Measured: Through study completion, an average of 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Surface Guided RadioTherapy (SGRT) without mask in people with Otorhinolaryngeal Cancer, run by Center Eugene Marquis at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measurement patient displacement during surface-guided radiotherapy sessions (time frame: Through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Aug 2026.
