Brief Summary

This pilot study will attempt to establish the feasibility of using tissue oxygen measurements and the protein, neurofilament light chain (NF-L), as potential biomarkers for chemotherapy-induced peripheral neuropathy (CIPN). Thirty (30) subjects scheduled to begin taxane-based chemotherapy for breast tumor will be assigned to receive an India ink injection under the skin of the foot. The ink will be used to make up to five (5) 45-minute "electron paramagnetic resonance" (EPR) oximetry readings prior to the start of chemotherapy. Subjects will undergo electrophysiologic assessments including nerve conduction studies, in addition to a neurological examination prior to the start of chemotherapy. Subjects will have the EPR oximetry readings, electrophysiologic tests, and neurological examination two more times: at the halfway point of their chemotherapy treatment -- or at the onset of CIPN symptoms -- and again after chemotherapy has been completed. Subjects will also have blood drawn prior to beginning taxane-based chemotherapy, prior to every scheduled chemotherapy treatment, and after completion of chemotherapy in order to test for neurofilament light chain (NF-L).

Study Arms (1)

EPR Oximetry

EXPERIMENTAL

All subjects in the study will receive the paramagnetic India ink injection to the foot. At three time points (pre-exposure, during-exposure or CIPN incidence, and post exposure), subjects will have three EPR oximetry readings, a neurological examination, and electrophysiologic testing.

Diagnostic Test: EPR Oximetry

Interventions

EPR OximetryDIAGNOSTIC_TEST

Subjects will have up to five EPR oximetry readings at each study visit. Subjects will place the foot with the paramagnetic ink injection between the two magnets of the EPR device. Continuous scans will be acquired for 10 minutes while the subject breathes room air, 10 minutes while the subject breathes enriched 100% oxygen, and 10 minutes while breathing room air again.

Limitations and Caveats

LIMITATION OF EPR DATA While it may be feasible to make serial measurements with the technique, there were technical problems with the sensor (India Ink), and no conclusions can be drawn in regard to oxygenation. Additionally, the ERP data are limited.
