Background & Aims:
Different nutritional screening tools have been proposed in childhood cancer, but none has shown convincing predictive capacity so far. The "nutrition screening tool for childhood cancer (SCAN)" has been specifically designed for this population and provides an easy-to-use, promising approach to identify patients at risk of malnutrition. We aim to: 1. Validate the SCAN tool prospectively in identifying malnourished patients or those who required nutritional support 2. Validate the SCAN tool prospectively in predicting toxicities or outcome. 3. Compare performance of a pediatric screening tool (STRONGKIDS) with SCAN.
Methods:
Children in our center with a new diagnosis of cancer from August 2018 to May 2019 were offered to participate in the study. Measurements (SCAN questionnaire, weight, height, body-mass index (BMI), and mid upper-arm circumference (MUAC)) were taken at diagnosis and at regular intervals throughout therapy. The last measurement was taken 6 months after finishing the intensive treatment phase. SCAN score at diagnosis was validated prospectively against variables of interest.
Results:
A total of 49 patients were recruited. When considering malnutrition during therapy the SCAN tool showed a sensitivity of 37.5% and negative predictive value (NPV) of 81%. Patients who required nutritional support were identified with a sensitivity of 50% and NPV of 62%. The SCAN tool was not able to predict increased toxicities, risk of relapse or decreased survival. The pediatric screening tool STRONGKIDS was unable to discriminate nutritional risk and labeled all 49 patients (100%) as medium or high-risk. Applying SCAN periodically during therapy increased sensitivity for identifying malnutrition to 87.5%.
Conclusions:
In our study, applying the SCAN tool at diagnosis showed low sensitivity in identifying patients who go on to develop malnutrition during therapy. However, patients labeled as "not at risk" were unlikely to need nutritional support in the form of nasogastric tube or total parenteral nutrition. Using SCAN throughout therapy could be helpful in building awareness for malnutrition and successfully discriminates between patients who need further support and those who don't.
