Cold-induced neuropathy is the most observed side effect of oxaliplatin. Presence of neuropathy is routinely assessed by electroneurographical examination. The use of electroneurography has not been a part of typical oncological monitoring and treatment protocols, leading to untreated, irreversible damage to patients' peripheral nerves, undiagnosed for long periods of time. 36 colorectal cancer patients followed FOLFOX4 with/without bevacizumab or XELOX were enrolled between .

Pre-treatment neurographic examination revealed presence of peripheral neuropathy in 10 (31.25%) patients; 6 (18.75%) had sensory neuropathy and 4 (12.5%) had mixed, sensorimotor neuropathy. After treatment examination revealed significant increase in the number of neuropathic patients; presence of peripheral neuropathy was observed in 19 patients (59%), sensory polyneuropathy was diagnosed in10 patients (31.25%) and mixed neuropathy was diagnosed in 9 patients (28.13%). Early electrophysiological monitoring followed by a symptom dependent oxaliplatin regimen would be highly beneficial for patients undergoing oxaliplatin treatment, improving their well-being and positively affecting their life quality.
