Science and CINAHL database analyzes and elaborates on the definition and connotation of nutritional impact symptoms. The search
period is from the establishment of the database to April 2024. The Walker and Avant conceptual analysis methods were applied to

and an increased economic burden. The symptoms of nutritional impact in cancer patients manifest as a complex and comprehensive
