Malnutrition is currently a major factor of morbidity and mortality, which poses a major public health problem in developing countries but also, albeit to a lesser degree and for different reasons, for industrialized countries. It is recognized that in countries "of the North", from 30 to 60% of hospitalized patients suffer from dénutrition.

In any case, it is covered by an imbalance between the contributions and needs; the two main mechanisms are a delivery failure (fasting, ingesting difficulty ...) and / or increased requirements (hypermetabolism ...). In cancer patients the Aero-Digestive Upper Airways (VADS), this imbalance is even more pronounced than the two mechanisms exist and potentiate. Patients included in this study are a population at risk, because of their therapeutic containing at least radiotherapy. It is recognized that this form of therapy exposes dental complications, mucous, saliva. These complications have a deleterious effect on the nutritional status of patients.

The diagnosis, treatment and prevention of dénutritions have an important place in the therapeutic strategies of this type of cancer because it is events whose incidence and morbid consequences are high and for which there are appropriate nutritional treatments in most cas. While the complete correction of malnutrition generally passes by the effective etiological treatment of the causal pathology, therapeutic efficacy of the latter is often conditioned by the nutritionnel state.

In addition to these concepts, investigators wants to study the benefits of a diet followed during the irradiation phase of patients with head and neck cancers and New treaties. We propose a randomized, phase III, open, multicenter, to evaluate the impact of a dietary consultation at home on the life quality of patients with head and neck cancer including first therapeutic sequence involves radiotherapy more or less aware. The duration of the study is 24 months.

The main objective is to evaluate the impact of a dietary consultation at home on the life quality of patients with head and neck cancer including first therapeutic sequence involves a more or less sensitized radiotherapy.
