Long-term peripheral neurotoxicity of cisplatin in patients with successfully treated epithelial ovarian cancer.

We evaluated clinically and neurophysiologically the immediate and long-term involvement of the peripheral nervous system in 22 selected patients with epithelial ovarian cancer successfully treated with DDP alone or in combination with non-neurotoxic drugs. While the motor nerves were unaffected, generally the involvement of sensory nerves was more severe at the examination performed several months after DDP discontinuation than at the evaluation performed after the "induction phase". We conclude that up to now the importance of long-term DDP-induced peripheral nerve damage has probably been underestimated. DDP-induced long-term damage is at least as severe as the immediate toxicity and, moreover, it is likely that complete recovery can occur, if ever, only years after DDP discontinuation.
