Objective Irreversible hearing loss is a frequent side effect of the chemotherapeutic agent cisplatin and shows considerable interpatient variability. The variant rs1872328 in the ACYP2 gene was recently identified as a risk factor for the development of cisplatin-induced ototoxicity in children with brain tumors. We aimed to replicate this finding in patients with osteosarcoma. Methods An independent cohort of 156 patients was genotyped for the rs1872328 variant and evaluated for the presence of cisplatin-induced ototoxicity. Results A significant association was observed between carriership of the A allele and cisplatin-induced ototoxicity after the end of treatment (P=0.027). Conclusion This is the first study replicating the association of ACYP2 variant rs1872328 with cisplatininduced ototoxicity in patients with osteosarcoma who did not receive potentially ototoxic cranial irradiation. Hence, the ACYP2 variant should be considered a predictive pharmacogenetic marker for hearing loss, which may be used to guide therapies for patients treated with cisplatin.
