Neuropathic pain in cancer patients: A brief review.

Abstract

Neuropathic pain (NP) is initiated or caused by a primary lesion or dysfunction in the nervous system. The NP in cancer patients is typically due to a combination of inflammatory, neuropathic, ischemic, infiltrative, and compression mechanisms that involve one or more anatomic sites. These patients will often have various types of co-existing pain syndromes and co-morbidities. Thus, any treatment plan needs to be individualized. After a thorough clinical assessment and evaluation, a combination therapy including anticonvulsants, antidepressants, N-methyl-D-aspartate antagonists, opiates, topical agents, and interventional procedures should be considered in these patients.
