[Nutritional support for individuals with advanced oncological pathology].

Cachexia increases the risk of therapeutic failure and reduces the quality of life for cancer patients. Patients with nutritional risks should be referred to a dietitian. Nutritional interventions primarily include meal adaptation and oral nutritional supplements. When cachexia is more severe, artificial nutrition is indicated for patients with a KPS (Karnofsky Performance Status) of 40 or above and a life expectancy of more than 6 weeks. When the digestive system is functional, enteral nutrition is recommended. Parenteral nutrition shows the same benefits but requires close monitoring. The decision to stop artificial nutrition is influenced by the medical condition, the patient's wishes, and the socio-cultural context.
