[During and after cancer: identification of high-risk nutritional situations]

"During and after cancer: identification of high-risk nutritional situations At the end of 2020, the French National Cancer Institute published a report presenting the state of knowledge on the impact of nutritional factors on clinical endpoints during or after cancer. This report is the result of a collective expertise by an expert group from the French Network for Nutrition And Cancer Research (NACRe Network, www.inrae.fr/nacre). This report shows that some nutritional factors have an impact on the mortality, and the risk of recurrence or second primary cancer in cancer patients. Therefore, high-risk nutritional situations can be encountered for certain cancer sites: from the diagnosis and throughout the healthcare circuit, weight loss (for lung and esophageal cancers), malnutrition (for lung, esophageal, colorectal, pancreatic, gastric and liver cancers), weight gain (for colorectal, breast and kidney cancers), or alcohol consumption (upper aerodigestive cancers) should be monitored; and after cancer treatments, excess weight should be detected (colorectal, breast and kidney cancers). These situations require nutritional assessments, or even support or management by healthcare professionals, in the context of tertiary prevention."
