Summary
Pediatric cancer patients treated with cisplatin experienced hearing loss, even at lower doses. Regular hearing evaluations are recommended for all children receiving cisplatin therapy to monitor for ototoxicity.
Area of Science:
- Pediatric Oncology
- Ototoxicology
- Audiology
Background:
- Cisplatin is a vital chemotherapy for pediatric cancers but can cause ototoxicity.
- Hearing loss is a significant concern for children undergoing cisplatin-based treatments.
Purpose of the Study:
- To investigate the frequency, severity, and clinical progression of cisplatin-induced hearing loss in Japanese pediatric patients.
- To identify potential risk factors associated with ototoxicity in this population.
Main Methods:
- Audiologic evaluations were performed on 55 children treated with cisplatin-based multimodal therapy between 1983 and 2012.
- Data analysis focused on the onset, time-to-progression, and severity of hearing loss.
Main Results:
- 35 out of 55 patients developed hearing loss, with incidence varying by age and combined therapies (chemotherapy and radiotherapy).
- Hearing loss occurred at cumulative cisplatin doses as low as 200 mg/m², with a median onset of 71 days post-treatment.
- Progressive hearing loss, persistent hearing failure, and the need for hearing aids were observed in several patients.
Conclusions:
- Ototoxicity from cisplatin therapy is a significant risk in pediatric cancer patients, influenced by age, combined treatments, and potentially genetic factors.
- Regular audiologic monitoring is crucial for all pediatric patients receiving cisplatin, regardless of cumulative dose.
- Further prospective research, including genetic polymorphism analysis, is needed to fully understand and manage cisplatin-induced ototoxicity.
