Serial Electrophysiologic Monitoring During Administration of Nerve-Toxic Chemotherapeutic Drugs

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

The study hypothesis is that changes in serially obtained nerve conduction study data obtained every 3-4 weeks in cancer patients receiving chemotherapy can be used to predict the development of a clinically significant / disabling drug induced neuropathy six and twelve months following the start of treatment. Patients with breast cancer, colon cancer, gastroesophageal cancer, and non-Hodgkins lymphoma will be enrolled. Six lower extremity nerves--three in each leg--will be electrically stimulated and their responses recorded at three to four week intervals coinciding with patient's scheduled chemotherapy.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients presenting to an oncology clinic for treatment of breast cancer, colon cancer, or non-Hodgkins lymphoma, or treatment of advanced gastroesophageal cancer

Inclusion Criteria:

  • Clinical diagnosis of untreated breast cancer, treated (advance stage) or untreated colon cancer, untreated non-Hodgkins lymphoma, or advanced gastroesophageal cancer scheduled to begin chemotherapy with either Taxol, oxaliplatin, or vincristine

Exclusion Criteria:

  • Individuals with an implanted electronic medical devices (cardiac pacemaker or defibrillator, vagus nerve stimulator, deep brain stimulator, intrathecal pump, others)
  • Individuals whose chemotherapy regimen will include nerve toxic drugs other than Taxol, oxaliplatin, or vincristine, or includes more than one of these three drugs in combination
  • Individuals whose screening nerve conduction studies show peroneal motor amplitude < 1 mV bilaterally or sural sensory amplitude < 3 uV bilaterally or no result obtainable
