Hypersensitivity reactions (HSRs) to oxaliplatin present a therapeutic challenge. The standard desensitization protocol consists of 12 infusion steps with 3 drug dilutions, often in an inpatient setting. Several years ago we implemented a simplified outpatient graded infusion protocol for oxaliplatin with 2 drug dilutions and 3 infusion steps. We performed a retrospective analysis of our experience to define the safety and outcomes associated with this simplified, ambulatory, graded infusion strategy. Between January 1, 2011 and December 1, 2020, 374 patients who had experienced an oxaliplatin-related HSR were treated via a 3-step graded infusion in the outpatient setting. Of these 374 patients, 283 (76%) did not experience a subsequent HSR, while 91 (24%) did experience a breakthrough HSR. Of the 374 patients, 19 (5%) experienced a grade 3 or 4 HSR. Three patients (0.8%) were hospitalized. There was no grade 5 (fatal) HSRs. Overall, the 374 patients received a median additional 3 cycles of oxaliplatin (range 1-41). The most common reasons for treatment discontinuation were disease progression (35%), breakthrough HSRs (24%), completion of treatment (21%), and toxicity other than HSR (20%). Fifteen patients who experienced breakthrough HSRs during a graded infusion were subsequently treated with the standard 12-step desensitization. Five of these 15 patients had an HSR during their initial desensitization and 5 developed an HSR on subsequent 12-step desensitizations. Thus, treatment was discontinued in 67% of these 15 patients due to persistent HSRs. Our data indicate that the simplified 3-step graded infusion protocol is a safe outpatient strategy for patients with a history of HSR to oxaliplatin. Copyright © 2022 Elsevier Inc.
