Cancers of the ENT sphere represent about 15% of all cancers in men and 2% in women. They mainly concern subjects between 45 and 70 years of age with a predominant role of ethylo-tobacco poisoning. Patients with upper aero-digestive tract cancers are particularly prone to malnutrition on the part of the tumor itself but also on the context (ethylo-tobacco intoxication, sedentary behavior, poor general condition), tumor localization involving reduction of intake (Mechanical obstruction, anorexia, pain), but also after treatment (chemotherapy, radiotherapy, surgery).
