Vomiting in children and adolescents receiving intravenous pegaspargase: a retrospective study.

ABSTRACT

Due to an evidence gap, the emetogenicity of intravenous (IV) pegaspargase was unable to be included in the clinical practice guideline classifying chemotherapy emetogenicity in pediatric patients. This single-center, retrospective chart review describes the proportion of pediatric patients who did not vomit during the acute phase (complete response; CR) after receiving IV pegaspargase and provides an emetogenicity classification using a preexisting framework. Of 44 patients who received IV pegaspargase between 2011 and 2020, 13 received a serotonin receptor antagonist plus dexamethasone or palonosetron alone and all experienced a CR. We, therefore, recommend classifying IV pegaspargase as moderately emetogenic.
