Paclitaxel pre-medication: A comparison of two steroid pre-medication protocols

Purpose To evaluate and compare the rate of hypersensitivity reactions between two low-dose steroid pre-medication regimens for paclitaxel-based treatments. Methods This was a single-center, retrospective, descriptive study, comparing the incidence of hypersensitivity reactions in two different dexamethasone pre-medication regimens that took place between July 2013 to December 2014. Patients who were paclitaxel-naïve with a diagnosis of breast or gynecological cancers were included. Patients in the early termination protocol were pre-medicated with a standard pre-medication regimen and if tolerated with no hypersensitivity reaction occurrence, all pre-medications were discontinued after the first two infusions. Patients in the low-dose steroid continuation protocol were pre-medicated with lower doses of dexamethasone, and if the infusion was tolerated with no hypersensitivity reaction, dexamethasone doses were further reduced after the first two infusions. Results A total of 120 patients were included for data analysis. The hypersensitivity reaction rate in the early termination protocol group was 7% (4 out of 60 patients). The hypersensitivity reaction rate in the low-dose continuation protocol group was 5% (3 out of 60 patients). All hypersensitivity reactions occurred during the first infusion, with no hypersensitivity reactions occurring once the dexamethasone pre-medications were discontinued or dose-reduced. All of the patients who experienced a hypersensitivity reaction were successfully re-challenged with paclitaxel and were able to continue their therapy uninterrupted. Conclusion Discontinuing dexamethasone pre-medication altogether after two uneventful infusions or decreasing the dose of dexamethasone paclitaxel pre-medication are both safe alternatives to high-dose steroid pre-medications recommended in product labeling.
