[Building Clinical Target Volume in laryngeal cancers using knowledge about modes of invasion of each location]. / Etablissement des volumes cibles anatomocliniques (Clinical Target Volume) pour les cancers laryngés en fonction de la localisation de départ et des modalités d'extension.

ABSTRACT

The purpose of this article is to propose a building model to delineate Clinical Target Volume in laryngeal cancers (squamous cell carcinoma). This model uses histological knowledge about the spread of laryngeal cancers. Firstly is described the spread, depending on primary location and anatomic structures. Then illustrated examples on Computed Tomography are provided. This delineation approach appears to be useful with 3D-CRT and IMRT for adapting dose delivery to the complex spread of laryngeal cancer.
