Objective Evaluation of Paclitaxel/Docetaxel-induced Neuropathy in Breast Cancer Patients

Quantitative measures that include additional aspects of peripheral neuropathy, such as pain, thermal allodynia, numbness and tingling are needed. We propose to evaluate several pharmacodynamics biomarkers in patients before and during chemotherapy: changes in nerve conduction velocity and amplitude, quantitative sensory testing (QST), computer based cognitive assessment, and rate of drop-out from treatment. The tests from this list that best correlate with decreased CIPN would be added to EORTC QLQ-CIPN20 scores and will provide an early indication of CIPN and/or CICI.
