Because of the improvement of cancer prognosis, long-term damages of treatments become a medical and public health problem. Among the iatrogenic complications, neurological impairment is crucial to consider since motor disability and pain have a considerable impact on quality of life of long cancer survivors. However, radiation-induced neuropathies have not been the focus of great attention. The objective of this paper is to provide an updated review about the radiation-induced lesions of the peripheral nerve system. ⋯ The importance of early diagnosis of radiation-induced neuropathies is underscored by the emergence of new disease-modifying treatments. Although the pathophysiology is not fully understood, it is already possible to target radiation-induced fibrosis but also associated factors such as ischemia, oxidative stress and inflammation. A phase III trial evaluating the association of pentoxifylline, tocopherol and clodronate (PENTOCLO, NCT01291433) in radiation-induced neuropathies is now recruiting.

Leprosy still affects 240,000 persons every year in the world. It is a particularly common cause of neuropathy and severe disabilities in developing countries. With increasing migration, new cases of leprosy are regularly diagnosed in developed countries, where it still remains rare and so underestimated. ⋯ Acute and severe neuritis occurs during reactional states, reversal reaction (Type 1) and erythema nodosum leprosum (Type 2). Multidrug therapy is advocated. The treatment of acute neuropathy needs a supplementary medical and sometimes surgical treatment.
