Oxaliplatin Desensitization After Hypersensitivity Reaction: A Single-Center Experience On More Than 300 Procedures.

610Background: Oxaliplatin is an essential drug in gastrointestinal oncology. Hypersensitivity reactions (HSR) occur frequently (incidence varying from 10% to 25%), leading to permanent treatment discontinuation. The present study aimed to report our experience of oxaliplatin desensitization in patients with history of HSR to oxaliplatin. Methods: We retrospectively reviewed all patients who received at least one infusion of oxaliplatin according to a desensitization protocol after prior history of HSR to oxaliplatin, from June 2011 until June 2017. HSRs were classified from NCI CTC-AE grade 1 (transient rash, fever u003c 38°C) to grade 4 (anaphylaxis). We applied in all cases a desensitization protocol in which the oxaliplatin infusion rate is gradually increased from 1mL/hr. to 150mL/hr., on an inpatient basis. Intravenous or hepatic arterial infusion was used depending on clinical setting. Results: Overall, 54 patients were included in this study, in whom HSR to oxaliplatin occurred after a median of 9 inf...
