“…Specific genomic mutations may predispose individuals to cisplatin-induced hearing loss, including gene variants for DNA adduct repair enzymes like ERCC2 and XPC ( Caronia et al, 2009 ; Turan et al, 2019 ); antioxidant enzymes; and drug efflux or membrane pumps ACYP2, ABCC3, COMT, and TPMT ( Ross et al, 2009 ; Xu et al, 2015 ). However, the predictive value in identifying these genomic variants in predisposing individuals for cisplatin-induced ototoxicity is currently poor ( Langer et al, 2020 ; Tserga et al, 2019 ). Enhanced cisplatin-induced hearing loss also occurs when co-administered with ototoxic therapeutics, including aminoglycosides, loop diuretics, and cranial radiation ( Clemens et al, 2016 ; McAlpine & Johnstone, 1990 ; Miller et al, 2009 ; Paulino et al, 2010 ).…”
