Review of Nutrition Guidelines and Evidence on Diet and Survival Outcomes for Cancer Survivors: Call for Integrating Nutrition into Oncology Care.

Several organizations have published nutrition guidelines for cancer survivors during and after treatment. This review compared nutrition guidelines for cancer survivors published in the United States (US) for the topics that are covered in the guidelines and evaluated the evidence that these guidelines are based upon. A team of researchers, patient stakeholders, and healthcare providers collectively identified five nutrition guidelines for cancer survivors in the US: the 2022 American Cancer Society Nutrition and Physical Activity Guidelines for Cancer Survivors, the 2018 American Institute for Cancer Research Cancer Nutrition Guide, the 2022 National Cancer Institute Physician Data Query and Eating Hints, the 2024 National Comprehensive Cancer Network Guidelines for Cancer Survivors, and the 2020 American Society for Clinical Oncology Guidelines. The five guidelines cover a comprehensive list of nutrition topics but overall promote to follow those recommendations for cancer prevention. This review also evaluated the current evidence from meta-analyses on dietary patterns and intakes of foods and nutrients in relation to survival outcomes among cancer survivors. Although the evidence on dietary patterns is strong, the evidence on most dietary factors is still limited and the current research was primarily conducted among breast and colorectal cancer survivors. While nutrition recommendations are available for cancer survivors, practical strategies need to be implemented to integrate nutrition into oncology care and help cancer survivors follow these recommendations. Further research is warranted to provide additional evidence on the role of nutrition in the health outcomes of cancer survivors and guide the development of evidence-based nutrition recommendations. REGISTRY AND REGISTRY NUMBER FOR SYSTEMATIC REVIEWS OR META-ANALYSES: The protocol is registered in PROSPERO: CRD42023429240.
