Nutrition and physical activity: French intergroup clinical practice guidelines for diagnosis, treatment and follow-up (SNFGE, FFCD, GERCOR, UNICANCER, SFCD, SFED, SFRO, ACHBT, AFC, SFP-APA, SFNCM, AFSOS).

This document is a summary of the French intergroup guidelines regarding the nutrition and physical activity (PA) management in digestive oncology. This collaborative work was produced under the auspices of all French medical and surgical societies involved in digestive oncology, nutrition and supportive care. It is based on published guidelines, recent literature review and expert opinions. Recommendations are graded according to the level of evidence. Malnutrition affects more than half of patients with digestive cancers and is often underdiagnosed. It has multiple negative consequences on survival, quality of life and risk of treatment complications. Consequently, in addition to anticancer treatments, supportive care including nutritional support and PA plays a central role in the management of digestive cancers. It is crucial to detect malnutrition (diagnostic criteria updated in 2019) early, 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 and PA in digestive oncology for each stage of the disease (perioperative setting, during radiation therapy, during systemic treatments, at the palliative phase, after cancer). Guidelines for nutrition and PA management aim at increasing awareness about malnutrition in oncology. They are continuously evolving and need to be regularly updated.
