The authors prospectively evaluated the effects of three different schedules of cisplatin (DDP) administration in 60 patients with advanced epithelial ovarian cancer. The individual total dose of DDP was 450 mg/m 2 in all three groups, and the anti‐cancer response at the end of treatment was similar for the different regimens. The clinical and neurophysiologic results confirmed that axonal sensory neuropathy occurred after the standard administration of DDP (75 mg/m 2 in 3‐week cycles) and probably not only the peripheral, but also the central sensory pathway, was involved. Although the total dose of the drug was identical, the two less conventional schedules were less neurotoxic. These results suggest that not only the total‐dose intensity, but also the single‐dose intensity are relevant in the onset of DDP‐induced sensory neuropathy; therefore, the use of less neurotoxic schedules may prevent or reduce sensory nerve damage.
