Desensitization in patients with hypersensitivity to platinum and taxane in gynecological cancers

BackgroundExposure to paclitaxel and carboplatin has the risk of developing hypersensitivity reactions (HSRs), which could necessitate using less effective treatments to avoid anaphylaxis. Desensitization to platinum and taxane HSRs can be used to complete chemotherapy according to the standard regimen; therefore, this study investigated rates and benefits of successful desensitization in patients with gynecologic cancers (GC).MethodsWe collected data from 241 patients with GC who had at least one cycle of platinum or taxane chemotherapy. The rate of HSRs and successful desensitization were evaluated, and an outcome analysis was conducted.ResultsThe rate of HSRs to platinum and taxane was 6.39% and 13.07%, respectively. We observed a 100% success rate of desensitization in our cohort. Patients with HSR were significantly younger (57.1 vs. 64.9 years, p = 0.030) in the taxane cohort. Importantly, the overall survival (OS) of patients with platinum and taxane HSRs who underwent desensitization was comparable to that of patients with no HSRs (platinum vs. controls; median OS 60.36 vs. 60.39 months, p = 0.31; taxane vs. controls; OS 80.29 vs. 60.00 months, p = 0.59).ConclusionThus, we show that desensitization for platinum and taxane HSRs is safe and effective, resulting in an outcome that is well comparable to patients without HSR. Based on these observations, desensitization procedures might be considered as standard of care before switching to less effective treatment for patients with GC.
