Genetic variants associated with cisplatin-induced ototoxicity

Cisplatin induces ototoxicity with a huge interindividual variation, which is at least partly based on genetic differences between the affected individuals. Identification of genetic variants that could predict the severity of ototoxicity is an important step towards a more individualized cisplatin treatment. Nevertheless, so far, only a few studies have assessed this issue. This review will address the prevalence of cisplatin-induced ototoxicity, its pathophysiology, quantification and associations with genetic variants. The recent progress in both phenotyping and genotyping is discussed.
