Evaluation and comparison of infusion reactions related to prophylactic medication timing for taxane administration

Abstract

Introduction

Taxane medications, paclitaxel, and docetaxel, are chemotherapy agents that have a higher incidence of reported hypersensitivity and infusion reactions. To help classify these reactions, the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) is utilized. Prophylactic medications have been used to decrease the incidence and severity of these events. At our institution, medications that patients can receive prior to the initiation of a taxane infusion are a histamine 1 receptor antagonist (H1RA), histamine 2 receptor antagonist (H2RA), a steroid or a combination of these medications. The purpose of this retrospective review was to compare the rates and severity of infusion reactions based on the timing of prophylactic medication administration in the first and second doses of taxane infusions.

Methods

Patients who received paclitaxel or docetaxel from January 30^th, 2022, through January 30^th, 2023, were included in the analysis. To assist in the identification of a reaction, taxane administrations were flagged for review if a rescue medication was administered after the start of a paclitaxel or docetaxel infusion. The rates and severity of infusion reactions were analyzed based on the timing of prophylactic medication administration. A sub-group analysis comparing infusion reaction characteristics between taxanes given, was performed.

Results

Of the 1486 taxane infusions that were completed within the year, 249 infusion reactions were confirmed and graded utilizing the NCI CTCAE. When examining the first and second doses of a taxane (N = 536), we identified 222 infusions reactions. The odds of a patient having an infusion reaction, during the first and second doses, was found to be less likely for patients given a prophylactic medication 30 min prior to receiving a taxane compared to those who did not receive a pre-medication (p = 0.037).

Conclusion

This multisite retrospective study showed that administration of prophylactic medications 30 to 80 min prior to the first and second infusion of a taxane was the optimal timing to decrease the likelihood of patients having an infusion reaction. No difference in the severity of the reaction was seen. Most patients were able to complete the entire infusion, regardless of what rescue medications were used following the infusion reaction.
