Abstract

BACKGROUND: There is increasing awareness of the importance of nutritional support in cancer treatment including the interaction with immunity. Immunonutrition is the provision of one or more nutrients (e.g. Vitamins A, D, or E, omega-3 fatty acids, arginine and glutamine) known to modulate immune function when given at levels above those normally encountered in the diet in order to support immune system function or modulate its activity, including control of inflammation. We reviewed the role of oral or enteral immunonutrition versus standard nutrition on infection and infection-related biomarkers in adult cancer patients undergoing chemotherapy.

METHODS: A systematic search of oral or enteral immunonutrition versus standard nutrition in adult cancer patients during chemotherapy with or without radiotherapy or haematopoietic stem cell transplant was conducted in MEDLINE, EMBASE and CENTRAL. The search was limited to randomised controlled trials. Our primary outcome was infectious episodes or immune-related biomarkers (e.g. immune cell numbers, inflammatory markers). Secondary outcomes included incidence of malnutrition or cachexia, non-infection related adverse events (AEs), rate of remission, survival, and delays or incomplete cycles of chemotherapy. Risk of bias was assessed using ROB 2.0 and study quality was assessed using CASP for RCTs.

RESULTS: The search yielded seven studies involving 521 patients (261 immunonutrition, 260 control) for analysis. All studies enrolled…
