AbstractPeripheral neuropathy ranks among the most common non-haematological adverse effects of a number of effective chemotherapeutic agents, including platinum compounds, taxanes and vinca alkaloids. Newer agents, such as bortezomib, thalidomide and lenalidomide, frequently exert similar neurotoxic effects on peripheral nerves. Chemotherapy-induced peripheral neuropathy (CIPN) may result from a variety of mechanisms and may be related to causal factors, such as single dose per course, cumulative dose and risk factors including treatment schedule, prior or concomitant administration of other neurotoxic agents, age and pre-existing peripheral neuropathy of other causes. The symptoms usually begin during chemotherapy and they may even worsen after cessation of treatment. In most of the cases, patients experience positive (pain, paresthesias) or negative (numbness) sensory symptoms in distal extremities in a stocking-and-glove distribution with less prominent motor and autonomic involvement. To date, several neuroprotective agents including thiols, neurotrophic factors, anticonvulsants and antioxidants have been tested in preclinical models and clinical open label or randomized controlled trials for their ability to prevent or treat symptoms of CIPN. Although several of these agents hold promise as possible neuroprotective factors, clinical data are still controversial and none have as yet robustly been proven effective against CIPN. This review critically looks at the pathogenesis, incidence, risk factors, diagnosis, characteristics and management of peripheral neuropathy associated with commonly used chemotherapeutic agents. We also highlight areas of future research to pursue.
