Prise en charge nutritionnelle en oncologie digestive. Synthèse des recommandations.

Gastrointestinal cancers have a high incidence with colorectal cancer being the main cause. Malnutrition has an extremely negative impact on quality of life and the toxicities of treatments. Supportive care, including nutritional support and adapted physical activity, plays a decisive role in the management of gastrointestinal cancers in association with conventional treatments. Nutritional status must be assessed as soon as the diagnosis is announced and during treatment, whether medical or surgical. In all cases, the nutritional care strategy must be defined with the patient at the start of their treatment. Whatever the nutritional care proposed, it is recommended to achieve at least energy intakes of 25 to 30 kcal/kg/day and 1 to 1.5 g of protein per kg/day. Gastrointestinal cancer surgeries are at high risk of morbidity, perioperative nutritional care is crucial and must be done according to the nutritional grade. Immunonutrition is also indicated perioperatively during these surgeries in order to reduce the risk of postoperative infectious complications. Multimodal care combining adapted physical activity should also be encouraged regardless of the type of care. [ABSTRACT FROM AUTHOR]
