Background:
A rising incidence of hypersensitivity reactions to oxaliplatin has been observed as a result of increasing clinical use. Epidemiological and clinical features of these reactions are reviewed.
Patients And Methods:
Records of patients treated with a modified FOLFOX regimen from March 1999 to March 2004 were reviewed.
Results:
One hundred and eighty patients were identified. Twenty-seven patients (15%) have been labelled as allergic to oxaliplatin, the proportion being higher among those receiving oxaliplatin in palliative second-line or above settings (19.6%) than in adjuvant or palliative first-line settings (10.2%). Some 2.2% of them developed grade 3-4 reactions. The reactions occurred after a mean (+/-SD) of 8.5 (+/-4.2) cycles (range 1-18). Among the 14 patients re-exposed to oxaliplatin, four (28.6%) developed hypersensitivity reaction, in two of whom (14.3%) reactions were grade 3-4 in severity.
Conclusions:
The risk of developing hypersensitivity reactions in patients receiving oxaliplatin should not be underestimated. The risk of developing potentially life-threatening hypersensitivity reactions should be explained to patients in the context of the potential benefits of such therapy. Patients receiving oxaliplatin infusion should be closely monitored. Once a patient develops hypersensitivity reaction to oxaliplatin, re-exposure should only be considered if the reaction is mild and there has been documented clinical benefit from previous doses of this agent.
