Nutrition and Quality of Life of Patients With Head and Neck Carcinoma After Radiotherapy

Undernutrition in cancerology is frequent because it's present for thirty to fifty percent of the patients at the time of the diagnosis. According to the recommendations of the French Speaking Society of Clinical Nutrition and Metabolism (SFNEP) of November 2012, a five percent loss of weight compared to the previous weight increases the risk of toxicity of the chemotherapy and worsens the patient's quality of life. The treatment of the tumors of the head and the neck comes along very often with a loss of weight (17.4 % after one year of radiotherapy according to the study of Larsson et al.) which varies with the chosen treatment, and shows a major risk at the patients whose therapeutic sequence involves a radiotherapy. The irradiation of the upper aerodigestive tract is source of aftereffects and late complications: xerostomia, oedemas of mucous membranes. The xerostomia, connected to the damage of the salivary glands, is a frequent complaint of the patients. It reveals or even increases, a dysphagia. According to Woisard, six months after the end of treatments, forty percent of the patients suffer from a dysphagia. All these complications limit quantitatively and qualitatively the food intake. The adaptation of the texture of the food is necessary by fifty four percent at three months of the end of treatments according to Logemann et al., and a few patients remain dependent on an long term enteral nutrition. Beyond a change of the nutritional state, the feeding difficulties or even the absence of resumption of an oral feeding are responsible for a social isolation. The meal which lost its dimension of pleasure becomes a source of fear and obsession for the patient as well as for his relations, and this fact generates family tensions. The quality of life of the patient is heavily affected. Ravasco showed in his study that the impact on the nutritional state of a nutritional care by dietary advices was more important as the prescription of oral nutritional supplements but based on a short period (the dietary intervention covered only the duration of the radiotherapy). But what would happen after the end of treatments? The investigators emit the hypothesis that a post-therapeutic systematic and regular dietary support has a positive impact on the prevention of the undernutrition among the patients affected by a first cancer of the upper aerodigestive tract whom therapeutic sequence involves a radiotherapy.
