Abstract
Background
Taxanes adjuvant therapy is recommended in certain high risk or metastatic tumors, particularly in lung and breast cancer, but also in other types of cancer like ovarian. The incidence of severe adverse drug reactions to paclitaxel is of approximately 10%.
Objectives
Analyze type I hypersensitivity reactions to paclitaxel and their management in the Mexican population.
Method
It is a retrospective, observational and descriptive study that included type I hypersensitivity reactions to paclitaxel reported from our database. Symptoms of hypersensitivity reactions to paclitaxel were classified and skin testing was performed with a 6 mg/mL paclitaxel concentration. The desensitization procedure consisted of a 12-steps, 3-bags of 250 mL protocol with a 6–7-hour duration.
Results
A total of 60 desensitization procedures were performed and were all completed successfully. All participants in our group were female, their median age was 44.5 years.
All of our patients had hypersensitivity adverse drug reaction to paclitaxel during their first exposure and within the first 10 minutes of infusion. 63.6% of the patients had a moderate hypersensitivity reaction to paclitaxel and 36.4% had a severe reaction.
Conclusions
Paclitaxel continues to be a common use drug and has a high rate of adverse drug reactions. This is the first study of hypersensitivity to paclitaxel in a Mexican population.
