Ultrasound for the Detection of Oxaliplatin-Induced Peripheral Neuropathy

Primary Objectives I. To compare tibial motor nerve ultrasound cross-sectional area between oxaliplatin-induced peripheral neuropathy patients and historical data among healthy adults. and oxaliplatin-induced peripheral neuropathy patients II. To compare sural sensory nerve ultrasound cross-sectional area between oxaliplatin-induced peripheral neuropathy patients and historical data among healthy adults and oxaliplatin-induced peripheral neuropathy patients Secondary Objectives I. To determine if the above changes in nerve cross-sectional area correlate with nerve conduction studies changes in the same oxaliplatin-induced peripheral neuropathy participants II. To determine if the above changes in nerve cross-sectional area correlate with changes on a self-reported neuropathy scale (QLQ-CIPN20) in the same oxaliplatin-induced peripheral neuropathy participants III. To determine if the above changes in nerve cross-sectional area correlate with intraepidermal nerve fiber density changes on skin biopsy in the same oxaliplatin-induced peripheral neuropathy participants
