Is cis-platinum vestibulotoxic?

Serial vestibular testing was performed on 34 patients undergoing cis-platinum chemotherapy and 12 age-matched normal subjects. Vestibular testing comprised caloric and low-frequency, sinusoidal rotational testing (0.01 to 0.16 Hz). Test-retest variability in the caloric and rotational vestibular assessment of the normal subjects formed the basis for evaluation of subclinical loss of vestibular function within our patient population. In spite of high-dose cis-platinum chemotherapy (100 mg/m2) with cumulative dosages to 1600 mg, no clear evidence of vestibular toxicity was found.
