Subjective and objective assessment of oxaliplatin-induced peripheral neuropathy.

Numbness and pain are currently evaluated using subjective methods such as the visual analog scale (VAS). However, because assessment of pain can vary greatly depending on the mood and physical state of the patient at the time of assessment, it is best to evaluate pain objectively. pain vision PS-2100 (PV) is an analytical instrument that was designed to quantitatively and objectively assess sense perception and nociception in patients. The present study examined the correlation of subjective and objective assessment of oxaliplatin-induced peripheral neuropathy (PN) using VAS and PV, respectively. The mean VAS and PV scores of PN were 20.5 (range 0-100) and 27.9 (range 0-416), respectively. The partial correlation coefficient was 0.274 (p = 0.0003). No strong correlation was observed between the results and a weak correlation was observed between VAS and PV.
