Ototoxicity from cis-platinum in patients with Stages III and IV previously untreated squamous cell cancer of the head and neck*

Abstract
Forty-four patients were evaluated for ototoxicity following treatment with the chemotherapeutic agent cis-platinum. Statistically significant hearing changes at 2,000 Hz (p < 0.001); 4,000 Hz (p < 0.05); and 8,000 Hz (p < 0.001) were observed. Chi-square analysis demonstrated that at 8,000 Hz patients who had lower than average thresholds prior to chemotherapy were more likely to experience greater threshold shift than those patients whose pre-chemotherapy thresholds were higher than average. In this patient sample, there was no significant correlation between serum creatinine levels and ototoxicty.
