    Abstract:
    OBJECTIVES: Platinum-based chemotherapy treatments are effective against a variety of pediatric malignancies. However, its use can lead to permanent hearing loss. The aim of this study was to evaluate the long-term effect of platinum chemotherapy on hearing and evaluate its progression. METHODS: Prospective cohort study. All records of pediatric patients receiving platinum-based chemotherapy between 2001 and 2006 were reviewed. Demographics and audiograms performed before, during, and following chemotherapy were analyzed. An updated audiogram and a video head impulse test were performed. A hearing ability questionnaire was also completed. RESULTS: Thirty-nine patients met the inclusion criteria. Of these, 12 patients were included in the study; 14 were deceased, 8 had incomplete data and 5 were excluded for other reasons. Median age at chemotherapy was 4.3 years (range 10 months-14.2 years). Seven patients had received cisplatin, two received carboplatin and three received both agents. Five had also received cranial irradiation. With a median follow-up time of 11.9 years, 58.3% had developed hearing loss and two patients wore bilateral hearing aids; 67% of the patients with hearing loss had worsening of their hearing in the long-term. All patients referred difficulties in various subscales measured by the questionnaire. Three patients had decreased vestibulo-ocular reflex gains. CONCLUSION: Platinum-induced hearing loss in pediatric patients can be progressive and debilitating. A long term audiometric follow-up of at least 10 years is suggested for these patients.
