[Target volumes in radiotherapy - head and neck tumors intensity - modulated radiation therapy (IMRT) of nasopharyngeal carcinoma: practical aspects in the delineation of target volumes and organs at risk].
The objective of this paper is to give some practical landmarks for the delineation of target volumes and organs at risk in Intensity Modulated Radiation Therapy for Nasopharyngeal Carcinoma. This delineation, drawn from anatomo-clinical data, natural history of the disease and radiological pre-treatment evaluation, seems to be easier to define than the delineation of other head and neck cancer localisations (oropharynx and oral cavity for example). Experience inside national and international cooperative groups should tend to standardize this initial and fundamental step of Nasopharyngeal Conformal Radiotherapy.
