Malnutrition is often underdiagnosed and affects more than half of patients with digestive cancers, especially in older patients and those with an advanced disease. It has multiple negative consequences on survival, quality of life and risk of treatment complications. Malnutrition pathophysiology is multifactorial and results from the negative imbalance between decreased energy and protein intakes and increased expenditures. Consequently, in addition to anticancer treatments, supportive care including nutritional support and physical activity plays a central role in the management of digestive cancers. It is crucial to early detect malnutrition (diagnostic criteria updated in 2019), to prevent it and to act against it at all stages of the cancer and at all times of the care pathway. In this context, we proposed recommendations for the evaluation and management in nutrition in digestive oncology at each stage of the disease (perioperative setting, during radiation therapy, during systemic treatments, at the palliative phase, after cancer).
