Abstract
This systematic review provides an overview of the effect of undernutrition on the pharmacokinetics of chemotherapy in children with cancer. PubMed, Embase, and Cochrane were searched to identify eligible studies. This study uses the definition for undernutrition from the World Health Organization and the Gomez classification. Four studies with a total of 668 children with cancer were included and n=121 (18%) were undernourished. Significant decreased clearance rates were found for vincristine in undernourished children compared to children with a normal nutritional status. Presenting outcomes only show significant changes in the pharmacokinetics of vincristine in undernourished children with cancer. However, data are scarce, groups were small, and none of the studies included severely undernourished children. In order to improve outcomes for (severely) undernourished children with cancer, more pharmacokinetic research is needed. The ultimate goal would be to develop subgroups, and ultimately individualized drug dosing in order to improve outcomes for children with cancer worldwide.
