Precision Nutrition in Oncology

Cancer is increasingly recognized as a systemic disease influenced by complex interactions between genetic, metabolic, immunologic, and environmental factors. Among these, nutritional status and metabolic health play a pivotal role in shaping disease progression and treatment response. Obesity and metabolic dysregulation, often driven by both genetic predispositions and lifestyle factors, are associated with poorer outcomes in oncology.This Research Topic is dedicated to advance our understanding of how precision nutrition strategies can be integrated into oncology to improve the metabolic health, immune function, and ultimately the prognosis and quality of life of cancer patients. More specifically, we aim to explore how multiomic and multidimensional data—including genomics, epigenomics, metagenomics, biochemical markers, anthropometric data, physical activity, sleep patterns, and dietary habits—can be leveraged to better characterize the oncologic patient. By integrating these data layers, researchers can develop personalized nutrition interventions to restore metabolic health and immune function, offering a complementary approach to conventional cancer therapies.We welcome contributions that investigate the role of gene-diet interactions, epigenetic modifications, and lifestyle factors in shaping metabolic health and immune responses in cancer. The ultimate goal is to foster the development of tailored nutritional strategies that enhance metabolic resilience, support immune competence, and improve clinical outcomes in oncology.These strategies include:.-Optimization of metabolic health and control of meta-inflammation of cancer patients.-Enhanced immune system function and immunotherapy outcomes..-Improvement of the nutritional health to mitigate treatment-related side effects..-Personalize dietary recommendations to align with genetic, epigenetic and microbiome profiles.We invite submissions of original research articles, reviews, mini-reviews, brief research reports, and short communications that address, but are not limited to, the following areas:.-Genetic Predisposition and Immunometabolic Alterations in Cancer: Studies on how genetic variants influence susceptibility to metabolic and immune dysregulation in cancer patients..-Nutrigenomics and Nutritional Modulation of Gene Expression: Research on how specific dietary components affect gene expression related to metabolism, inflammation, and immune function..-Epigenetics and Diet in Cancer ProgressionInvestigations into how dietary factors induce epigenetic changes (e.g., DNA methylation, histone modifications) that influence cancer development and progression..-Multi-Omic and Multidimensional Patient Profiling: Integration of genomic, transcriptomic, proteomic, metabolomic, microbiome, and lifestyle data to improve patient stratification and nutritional intervention design..-Personalized Nutrition Strategies in Oncology: Development and validation of individualized dietary plans based on multi-omic data to enhance metabolic and immune resilience..-Mechanistic Insights into Diet-Gene Interactions: Experimental studies elucidating molecular pathways through which nutrition influences cancer biology..-Diet and microbiome interactions in cancerPlease note that manuscripts consisting solely of bioinformatics or computational analysis of public genomic or transcriptomic databases which are not accompanied by robust and relevant validation (clinical cohort or biological validation in vitro or in vivo) are out of scope for this Research Topic.
