Conditions
Summary
This study aims to evaluate nerve excitability in participants with cisplatin-induced peripheral neuropathy (cis-PN) using threshold tracking nerve conduction studies (TTNCS). By assessing changes in nerve excitability parameters, the study seeks to enhance understanding of the pathophysiology of cis-PN and identify early markers of neurotoxicity in participants undergoing cisplatin-based chemotherapy.
Eligibility
Inclusion Criteria4
- Adults age ≥ 18 who will begin cisplatin-based chemotherapy either alone or in combination with other agents that are not known to cause neuropathy.
- Participants must have adequate hematologic parameters to allow chemotherapy.
- Adults age ≥ 18 with a diagnosis of cis-PN.
- The last dose of cisplatin must be ≥ 3 months prior to study enrollment. Patients who may have been previously enrolled in Cohort A of this study are eligible to participate in Cohort B if they continue to have cis-PN symptoms 3 months after completion of cisplatin therapy.
Exclusion Criteria17
- Pre-existing peripheral neuropathy;
- Family history of a genetic/familial neuropathy;
- Any contraindication for treatment with cisplatin as determined by their primary oncologist;
- Chemotherapy regimen combining cisplatin with another known chemotherapy agent that may cause peripheral neuropathy;
- Patients with cardiac or spinal stimulating devices;
- Women who are pregnant or breastfeeding;
- Adults with impaired consent capacity as patients must be able to fill out questionnaires regarding their neuropathy symptoms;
- Other medical conditions that in the opinion of the treating physician would make the protocol unreasonably hazardous for the patient;
- Patients not considered to be able to comply with the protocol.

Interventions
Measurement of nerve excitability parameters, including response to sub-threshold pre-pulses and other stimuli. The DS5 0 Isolated Bipolar Constant Current Stimulator is a non-invasive, non-therapeutic device that provides controlled electrical stimuli for detailed function assessment of the superficial radial, superficial peroneal, ulnar, and sural nerves.
