Results. At the end of 5-years follow-up ototoxicity was significantly increased compared to that at observed the end of chemotherapy (52.5% vs 39.5%, p<0.001). A late onset of hearing loss was experienced in 13.1% of children while in 26.3% progressive hearing loss was measured. Deafness at the end of chemotherapy and irradiation was significant prognostic factor for late ototoxicity outcomes (Odds Ratio 7.2 – CI:1.67–31.1 – p<0.01 and 5.25 – CI:1.26–21.86 – p<0.01 respectively). No significant differences were found between cisplatin and combined treatment (i.e. cisplatin shifted to carboplatin during monitoring for the onset of ototoxicity) and ototoxicity was not associated with platinum compounds cumulative dose (p>0.05). 13.1% of children needed hearing aids at the end of follow-up.
