Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Radiotherapy (RT), surgery and chemotherapy (CT) are treatments for head and neck cancers, used alone or in combination. Conformal RT with Intensity Modulation (IMRT) is currently the reference technique. IMRT requires a precise definition of the target volumes to be treated and the anatomical structures to be protected from irradiation. Most studies of head and neck cancers published in the literature demonstrate the variability in the contouring of the target volumes between radiotherapists. This may have an impact on dosimetry. To date, no studies have evaluated the impact of the ENT surgeon's evaluation in volumes contouring. The aim of this study is to compare the volumes determined by the radiotherapists alone and those determined jointly by the radiotherapists and the ENT surgeon.

Interventions

Learn about the drugs, procedures, or behavioral strategies being tested and how they are applied within this trial.

Systematic consideration of the advice of the ENT surgeon in the determination of the radiotherapy target volumes in head and neck cancers.

The contouring of the different target volumes will be first performed by the radiotherapists. During the Head and Neck Tumor Board, the volumes initially determined by the radiotherapists will be analyzed jointly by the radiotherapists and the patient's ENT surgeon to carry out, if necessary, modifications, taking into account clinical observations, intraoperative findings (if any) and endoscopy findings. Concordance parameters will be calculated in a second time with the determined volumes (in particular, index of concordance, coefficient of similarity).
