Treatment for paraneoplastic neuropathies.

Background: It is not unusual to observe peripheral nervous system involvement in people with tumours outside the nervous system. Any part of the peripheral nervous system can be involved, from sensory and motor neurons to nerve roots and plexuses, from distal trunks to neuromuscular junctions. Pathogenesis also varies from direct infiltration by cancer cells, to treatment toxicity, to metabolic derangement, cachexia, infections and paraneoplastic syndromes.
