Background/Aim: Malnutrition is a dangerous comorbidity in children with cancer that can affect tolerance
to treatment modalities such as chemotherapy and radiotherapy. It also adversely affects the treatment
outcome and overall survival. It has been known that low Z score of body mass index (BMI) indicates
malnutrition. This study aims to underline the effects of oral nutritional supplementation (ONS) on pediatric
Methods: All records were collected from Kocaeli University Hospital, Department of Pediatric Oncology,
Kocaeli, Turkey, and analyzed. Weight, height, and BMI status of sixty patients who received ONS with
cancer treatment were recorded during visits up to 8 months after the start of ONS. Statistical analyses were
maintained on the whole cohort as well as on following tumor sub-groups: CNS tumors (13.3%), lymphoma
(18.3%), other tumors (68.3%).
Results: Sixty malnourished pediatric oncology patients (64.6% male, 35.4% female) were included in the
study cohort. BMI values of the majority (60%, P<0.05) of patients increased after ONS treatment while
those of 40% decreased. BMI values also increased in the case of other tumors and lymphoma sub-groups
(P<0.001 and P=0.012, respectively).
Conclusion: This study underlined the benefits of ONS treatment in terms of BMI status among pediatric
oncology patients. The recovery rate of nutritional status depends on malignancy, cancer type and location.
