Radiotherapy plays an important role in the curative treatment of head and neck cancer. This treatment however is associated with significant acute and late toxicity with xerostomia and dysphagia severely implicating the patient's quality of life. With highly conformal radiotherapy techniques it is possible to decrease de dose to the organs at risk while maintaining adequate doses to the tumour. In order to adequately register the effect of these techniques it is imperative to obtain standardized information on the acute and late treatment effects. With this study the investigators want to evaluate this toxicity using standardized and validated questionnaires during follow-up. This data will then be correlated to the doses delivered to the specific organs at risk.
