Paraclinical evaluation of side-effects of Taxanes on auditory system.
Ototoxicity is one of the major causes of hearing loss and balance system disorders. Taxanes are a new group of anti-neoplastic agents used for chemotherapy; examples include Paclitaxel and Docetaxel. In this study, ototoxicity of these drugs has been evaluated in order to provide a means of adjusting the doses to avoid these complications. A prospective analytical study was carried out on 103 known cases of breast and ovarian cancer, during 2004 to 2006 (20 months), in the Otolaryngology, Head and Neck Surgery Department of Ahwaz University of Medical Sciences of Tehran. All patients (mean age 45 +/- 2.3 years) were treated with Taxanes. The first evaluation of hearing (using pure tone audiometery) was performed before starting treatment, the second in the middle of the treatment period and the last at the end of treatment. Results showed that nausea and vomiting were the most common side-effects of the drugs used. No significant side-effects of Taxanes, on the audiovestibular system, were observed. In conclusion, little information concerning the ototoxic effect of Taxanes has been reported in other studies, and, in the present investigation, no significant effect on the auditory system was found.
