Yoruk MA, et al. - In this prospective study, researchers evaluated malnutrition risks and nutritional status over a 6-month treatment period measured at regular intervals. The study sample consisted of 74 pediatric oncology patients with hematologic malignancies (n=56) or solid tumors (n=18) and a median age of 78.5 months. At diagnosis, the rate of patients with high risk for malnutrition was 28.4% through Screening Tool for Risk of Impaired Nutritional Status and Growth tool and 36.5% through Pediatric Yorkhill Malnutrition Score. The data presented in this work showed a decline in the prevalence of undernutrition and malnutrition over a 6-month treatment period with improved anthropometrics despite an initial deterioration in all subgroups of malignancy and even in baseline screening patients with an elevated risk of malnutrition. Solid tumors and acute lymphoblastic leukemia appear to be associated with an increased probability of undernutrition and overnutrition during therapy, respectively.
