Dietary problems are frequently reported in cancer patients and survivors which may reduce quality of life and cancer survival. Nurses' role in dietary management is recognized as important, but review evidence on nurse-led dietary interventions for cancer patients and survivors is lacking. This review aims to summarize evidence on nurse-led dietary interventions for cancer patients and survivors. Ten electronic databases (PubMed, CINAHL, CENTRAL, EMBASE, Web of Science, Ovid, CNKI, Wan Fang, CQVIP, Index to Taiwan Periodical Literature System) were searched from inception dates to November 11, 2021, using the key search terms "cancer/nutrition/nurse-led/intervention." Eligible studies were experimental studies on nurse-led dietary interventions for improving dietary intake in cancer patients and survivors published in peer-reviewed journals in English or Chinese. The methodological quality of the included studies was evaluated using the revised Cochrane risk-of-bias assessment tool. Data were extracted and summarized descriptively. Three randomized controlled trials on nurse-led dietary counseling published between 2005 and 2018 were included, with an overall high risk of bias. Two studies found positive intervention effects in improving fruit and vegetable intake, while the other study demonstrated an increase in energy intake. This is the first systematic review to summarize the evidence on nurse-led dietary interventions for cancer patients and survivors. Although available studies are limited, a positive trend was identified in that nurse-led dietary interventions are effective in increasing dietary intake in cancer patients and survivors. Additional studies in this field are required to further explore nurses' role in the development of nutritional oncology care.
