Risks and mitigation strategies to prevent etoposide infusion-related reactions in children.

Etoposide is an antineoplastic agent widely used for treatment of many pediatric cancers. Etoposide has been associated with infusion-related reactions. In this brief report, we compare etoposide infusion-related reactions that occurred over a 10-year period at two freestanding pediatric hospitals. Infusion reactions occurred in 1% of patients at two hospitals across the study period. Rates of 4.8%, 3.4%, and 7.9% were observed at Children's Mercy Hospital during 2018, 2019, and 2020, respectively, after the implementation of in-line filters during etoposide infusions in late 2017. Of the 32 patients who experienced adverse reactions, 41% were rechallenged after the reaction and all were able to tolerate at least one future dose with either pre-treatment or extending infusion duration. This work highlights the importance of a multicenter approach to investigating adverse drug reactions (ADRs) as variation in practice can provide key information about ADRs and potential risk factors.
