The draft systematic evidence review for this workshop is now available. Please submit your comments by August 23, 2022
As many as 80% of people with cancer experience malnutrition. Malnutrition, a condition caused by not getting the right balance of nutrients such as protein, vitamins, and minerals, can interfere with cancer treatment and increase the risk of complications, hospitalizations, and death.
Cancer and cancer treatment can have nutrition-related side effects like nausea, appetite and taste changes, and fatigue and make it hard for people with cancer to eat well and absorb nutrients from food. People who have upper gastrointestinal tract, head, neck, lung, blood, gynecological, or colorectal cancers are more likely to experience nutrition problems. People with cancer who have excess weight or obesity are also at greater risk for complications related to poor nutrition.
Cancer-associated malnutrition may be preventable. Studies have shown that interventions like medical nutrition therapy can help people with cancer keep a healthy body weight, maintain strength, respond to cancer treatment, and have a better quality of life.
While malnutrition is common among people with cancer, nutritional screening and interventions are not standard parts of outpatient cancer care in the United States. There are no national clinical guidelines to prevent or treat cancer-associated malnutrition before or during cancer treatment, and currently there is a lack of high-quality evidence about how nutritional interventions affect cancer health outcomes. Health care providers and decision-makers need high-quality research on cancer-associated malnutrition screening, nutritional support and therapies, and a comprehensive review of the evidence to inform development of clinical guidelines for preventive care.
Guided by the key questions listed below, speakers in this P2P workshop will assess the scientific evidence on how nutritional interventions affect cancer health outcomes. After the workshop, an independent panel will draft a report on evidence gaps and identify priorities for future research.
P2P workshops are free and open to the public. You can register to attend using the links at the top of the workshop page.
There are opportunities to comment and ask questions throughout the workshop either through the Webex chat function or by emailing
The public is also encouraged to submit comments on the draft panel report when it is posted on the ODP website for a public comment period.
