title: [Delineation for oral cavity and oropharyngeal cancers].
abstract: The aim of this article is to present the determination and the delineation of target volumes for oral cavity and oropharyngeal carcinomas treated with intensity-modulated irradiation. The delineation on the computerized tomography scanner (CT scan) requires a precise method because of the complexity of the head-and-neck anatomy. Different elements are necessary: clinical examination, diagram of the initial tumor, surgical and pathological reports and medical imaging (CT scan, magnetic resonance imaging and fluorodeoxyglucose positron emission tomography). The clinical target volumes, the planning target volumes, the organs at risk and the planning organs at risk volumes are discussed. The concept of selectivity of the potential subclinical disease near the primary tumour and the selection of neck nodal targets are specified according to the literature.
