BACKGROUND: Hypersensitivity is a well-known complication of the platinum agents cisplatin and carboplatin. Although hypersensitivity to oxaliplatin has been noted, the incidence varies significantly in reports. Risk factors for developing reactions specifically to oxaliplatin have not been evaluated. We report the 5-year incidence of hypersensitivity to oxaliplatin in our clinical program, the patient and disease characteristics associated with its occurrence, and review the literature.
METHODS: Clinical information on all patients treated with oxaliplatin between September 2002 and August 2007 was retrospectively reviewed. Data from patients who experienced hypersensitivity were compared to patients treated with this agent who did not. Risk factors investigated included age, sex, diagnosis, disease stage, presence of preexisting allergies, chemotherapy received, and use of oxaliplatin in front-line versus salvage therapy.
RESULTS: 247 patients received oxaliplatin, with 29 experiencing hypersensitivity, for an incidence of 11.7% (95% CI 7.7-15.8). Grade 3/4 events occurred in 1.6%. Hypersensitivity was associated with younger mean age (54.9 +/- 12.5 vs. 60.4 +/- 12.4 years with reactions vs. those without, p = 0.02), female gender (17.2% of females vs. 6.4% of males, p = 0.01) and with use of oxaliplatin as salvage therapy (23.9% second-line or higher vs. 9.1% front-line, p = 0.01).
CONCLUSIONS: Our data demonstrate an incidence of hypersensitivity to oxaliplatin of 11.7%, with grade 3/4 events in 1.6%. As use of this agent becomes more widespread, increased vigilance for this potentially serious complication should be high, especially amongst younger patients, females, and with the use of oxaliplatin as salvage therapy; three newly recognized potential risk factors.
