This is a translational clinical study aiming to develop approaches to process effectively human tissues and identify biomarkers for painful and non-painful chemotherapy-induced peripheral neuropathy (CIPN). This study will involve obtaining two skin biopsies representing affected and non-affected parts of each patient’s limb. Painful and non-painful neuropathies will be determined by a variety of standard approaches implemented by a neurologist Dr. Bhavaraju-Sanka.
