[Neuropathy caused by cisplatin. 7 cases including one with an autopsy study]

The clinical, electrophysiological and histopathological features in seven cases of cisplatinum peripheral neuropathy are reported and compared with the literature data. The neuropathy appears for an average intake of 500 mg/m2 of DDP. The symptoms are those of a symmetric, distal, predominantly sensitive neuropathy of an axonal type with major involvement of proprioception. Neurological improvement is poor after withdrawal of the drug. A post mortem study performed in one case showed a degeneration of the posterior column in the cord and residual nodules of Nageotte in a lumbar spinal ganglion. The systematic study of the tendon reflexes and distal pallesthesia in subjects treated with the drug, may reveal the neuropathy before the onset of the most disabling symptoms (paresthesia, ataxia, pain, Lhermitte's sign).
