Oxaliplatin is an anticancer agent commonly used in the treatment of colorectal cancer. However, the development of neuropathic pain under treatment limits its use. These are manifested by acute hyperesthesia / distal cold allodynia and chronic course of hypoesthesia. It is widely reported that these pains are consecutive to hyperexcitability of some ioniques2 channels (mainly sodium and potassium channels). However, the pathophysiological mechanisms of neurotoxicity are multifactorial and still imperfectly described. Since May 2014, the hospital group Paris Saint Joseph led the pilot study LIPIDOXA whose challenge is to quantify / measure NAION and explained by a biochemical approach, specifically Lipidomics. The CANALOXA study is the logical continuation of LIPIDOXA study insofar design methodology relies heavily on techniques developed for LIPIDOXA study and that the expected results will be complementary to those of LIPIDOXA.
