Dietary modifications for enhanced cancer therapy

Abstract

Tumours depend on nutrients supplied by the host for their growth and survival. Modifications to the host’s diet can change nutrient availability in the tumour microenvironment, which might represent a promising strategy for inhibiting tumour growth. Dietary modifications can limit tumour-specific nutritional requirements, alter certain nutrients that target the metabolic vulnerabilities of the tumour, or enhance the cytotoxicity of anti-cancer drugs. Recent reports have suggested that modification of several nutrients in the diet can alter the efficacy of cancer therapies, and some of the newest developments in this quickly expanding field are reviewed here. The results discussed indicate that the dietary habits and nutritional state of a patient must be taken into account during cancer research and therapy.

    Garcia-Bermudez, J. et al. Aspartate is a limiting metabolite for cancer cell proliferation under hypoxia and in tumours. Nat. Cell Biol. 20, 775–781 (2018). This study studied the dependency of tumours on aspartate under hypoxic conditions, and it provides an interesting example of potential specificity of tumour targeting by dietary deprivation of nutrients that might be achieved by tumour-specific vulnerability, in this case owing to the hypoxic conditions at the tumour site.

    Sousa, C. M. et al. Pancreatic stellate cells support tumour metabolism through autophagic alanine secretion. Nature 536, 479–483 (2016). This study shows that although alanine has a unique metabolic role in pancreatic ductal adenocarcinoma, it is not likely to be a good target for dietary modifications because it is supplied to the tumour by surrounding stroma cells, illustrating the importance of understanding a tumour’s sources of nutrition.
