Objective: To assess the frequency and factors associated of the provision of nutrition support (NS) in the last 30 days of life in patients with advanced cancer in the palliative or non-palliative setting.Methods: Retrospective cohort study in palliative and non-palliative care units at a specialized cancer center for oncology in Brazil. The use of oral nutrition supplements (ONS) and enteral (EN) and parenteral (PN) nutrition in the 30 days before death were assessed. Results:The 239 patients included were predominantly older (>60 years; 63.2%) and female (61.1%). The use of ONS was lower in palliative than non-palliative care during the last 30 (52% vs. 6%), 7 (42% vs. 4%), and 3 (23% vs. 2%) days before death (all P < .001). The use of EN and PN was lower in palliative care, decreasing with the approach of death. The independent factors associated with ONS in non-palliative care were (odds ratio): breast tumor (3.03), hypoalbuminemia (1.10), and nutrition risk (16.98); in palliative care, only the Karnofsky Performance Status (KPS) ≥40% (1.24) was associated to the use of ONS. The use of EN and PN was associated with head-neck (HN) tumor in both settings (5.41) in non-palliative and (8.74) in palliative. Others independent factors were: hypoalbuminemia (3.12) in non-palliative care and KPS (1.31) in palliative care. Conclusions:The use of NS near the end of life was high in the non-palliative and less frequent in palliative care setting. The factors associated with NS differed according to the clinical oncology setting, with one of the factors in palliative care being a better prognosis.

ObjectiveTo evaluate current evidence of the effect of specialised nutritional interventions on nutritional status, survival, quality of life and measures of functionality in patients with incurable cancer.MethodsSystematic literature review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using PubMed/MEDLINE, EMBASE, Scopus, LILACS and Cochrane Library databases. Clinical studies that evaluated different specialised nutritional interventions, such as nutritional counselling, oral nutritional supplementation (ONS), enteral nutrition (EN) and parenteral nutrition (PN), were eligible. Only studies classified as being of high methodological quality (ie, low or moderate risk of bias) were included.ResultsA total of 22 studies reporting on 2448 patients were deemed eligible. Five types of specialised nutrition were observed: mixed (multimodal nature, ie, dietary counseling, ONS, physical activity and/or drugs) (n=12), ONS (n=5), PN (n=3), EN (n=1) and multidisciplinary team counselling (n=1). Benefits of any kind from the interventions were reported in 14 (63.6%) studies, mainly resulting from mixed intervention. Nutritional status improved in 12 (60.0%) of 20 studies and quality of life improved in eight (50.0%) of 16 studies. Few studies have evaluated the influence of nutritional interventions on survival and measure of functionality, and have not shown improvement in these outcomes.ConclusionDespite the limited evidence, specialised nutritional interventions can yield positive effects for patients with incurable cancer, mainly in their nutritional status and quality of life.
