Otoprotectant Properties of Sodium Thiosulfate: Results of the SIOPEL 6 Study
Penelope Brock, MD
More than one-half of pediatric patients who are given cisplatin for cancer will develop some form of hearing loss following treatment.
At the 49th Congress of the International Society of Paediatric Oncology held in Washington D.C., October 12-15, Penelope Brock, MD, of Great Ormond Street Hospital in London, UK, presented the final results of the SIOPEL 6 study, showing that the addition of sodium thiosulfate to a cisplatin-based regimen for treating children with hepatoblastoma significantly reduced the percentage of patients who experienced hearing loss.
In the cisplatin alone group, 30 of 45 patients showed signs of hearing loss in comparison to only 20 of 54 patients in the cisplatin plus sodium thiosulfate group.
Overall survival was similar in both groups and the additional of thiosulfate was well-tolerated.
