Contribution of the ENT (Ear, Nose, and Throat) Surgeon's Clinical Evaluation to the Contouring of Target Volumes and Organs Eligible for Radiotherapy 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).
