Pain Control Using Neuromodulation in Patients Undergoing Definitive Chemoradiotherapy for Head and Neck Cancer

Not Applicable

Completed

• Conditions: Cancer of Head and Neck
• Interventions: Device: Transcranial Direct Current Stimulation (tDCS)

• Registration Number: NCT02366611
• Lead Sponsor: University of Michigan

Brief Summary

The purpose of this study is to determine if Transcranial Direct Current Stimulation (tDCS) can reduce pain perception associated with the effects of receiving definitive radiation therapy or chemoradiotherapy in head and neck cancer (HNCa) patients.

Detailed Description

The goal of this study is to investigate the effectiveness of tDCS as a novel pain relief modality for odynophagia due to mucositis in patients with locally advanced head and neck cancer undergoing definitive radiation therapy or chemoradiotherapy. Participants will be randomized into one of two arms: (1) Treatment: radiation/chemoradiotherapy standard of care + tDCS neuromodulation or (2) Control: radiation/chemoradiotherapy standard of care only.

Patients in the treatment arm will undergo tDCS stimulation on the day of their radiation/chemoradiotherapy appointments, prior to receiving treatment when doing tDCS session in clinic or after to receiving treatment when doing tDCS session at home. This will occur daily (5 days per week) during the second and third weeks of therapy, three times per week during the fourth and fifth weeks, and twice per week during the sixth and seventh weeks.

Patients will also have EEG and fNIRS recordings during the study. This will occur at the pre-study visit, the first stimulation appointment, the third week, the 7th week, and during the follow-up appointments (one-week and one-month).

Arm && Interventions

Group	Intervention	Description
Transcranial Direct Current Stimulation (tDCS)	Transcranial Direct Current Stimulation (tDCS)	tDCS is a method of non-invasive brain stimulation that is based on the application of a weak direct current to the head that flows between two relatively large electrodes-anode and cathode. tDCS offers a unique analgesic modality of central pain neuromodulation by altering the activity of key sensory and motor cortical structures. Participants in this arm will undergo 20 tDCS sessions, tDCS in clinic and remotely supervised tDCS, and 2mA of transcranial direct current stimulation will be applied for 20 minutes.

Primary Outcome Measures

Name	Time	Method
EEG Spectrum Pre-Post tDCS Session	Pre/Post-tDCS Session	EEG data power spectrum analysis. Pre/Post-tDCS session. The report was divided into five frequency bands: * Delta = 0-4 Hz; * Theta = 4-7 Hz; * Alpha = 8-15 Hz; * Beta= 16-31 Hz; * Gamma 32-50 Hz; The data was recorded at P3, Fz, Cz, F3, Fp1, Fp2 points in the international 10-20 system.; Note: the control participant's data was not reported due to limited number of participant in the control group.
Visual Analog Scale (VAS)	Pre-treatment (baseline), throughout treatment (once a week for 7 weeks), 1 week and 1 month follow-ups (post-treatment)	A Visual Analog Scale (VAS) will be used to assess patient-reported odynophagia at weekly Radiation Oncology on-treatment visits (OTVs). The VAS is a traditional pain assessment tool that has been used and validated widely in both clinical and research settings, including studies of oral mucositis pain. This scale ranges from 0-100, in which 0 means no odynophagia, and 100 means highest level of odynophagia ever.
EEG Power Spectrum Week1/Week7	Week1/Week7	EEG data power spectrum analysis. Week1 and Week 7 difference. Note: the control participant's data was not reported due to limited number of participant in the control group. The report was divided into five frequency bands: * Delta = 0-4 Hz; * Theta = 4-7 Hz; * Alpha = 8-15 Hz; * Beta= 16-31 Hz; * Gamma 32-50 Hz; The data was recorded at P3, Fz, Cz, F3, Fp1, Fp2 points in the international 10-20 system.; The analysis was done using EEGLab V 14.1.1.

Secondary Outcome Measures

Name	Time	Method
Oral-Mucositis Weekly Evaluation - Overall	Pre-treatment (baseline), throughout treatment (once a week for 7 weeks), 1 week and 1 month follow-ups (post-treatment)	1-7 scale grading self-evaluated overall physical condition, 7= Excellent, 1 = Very poor.
Positive and Negative Affect Schedule	Pre-treatment (baseline), throughout treatment (once a week for 7 weeks), 1 week and 1 month follow-ups (post-treatment)	The General Positive and General Negative scores in the PANAS forms are reported for both pre- and post- treatment. The General Positive (GP) and General Negative (GN) scores were reported. Each score ranges from 10-50, in which 10 = lowest (positive/negative emotional level) and 50 = highest (positive/negative emotional level).
Washington Quality Of Life Questionnaire	Pre-treatment (baseline), Week 7 of treatment, 1 week and 1 month follow-ups (post-treatment)	The Washington Quality Of Life questionnaire (QOL) is one of the most frequently reported health-related QOL questionnaires in head and neck cancer. This questionnaire scaled from 0 (worst) to 100 (best) according to the hierarchy of response.
Patient Weight	Pre-treatment (baseline), throughout treatment (once a week for 7 weeks), 1 week and 1 month follow-ups (post-treatment)	Participant's weight each measurement time point. Note: 0 means data missing.
Present Pain Intensity Index in McGill Questionnaire Pre-tDCS Treatment	Pre-treatment (baseline), throughout treatment (once a week for 7 weeks), 1 week and 1 month follow-ups (post-treatment)	The Present Pain Intensity (PPI) index is recorded as a number ranges from 0 to 5, in which each number is associated with the following words: 0 no pain, 1 mild, 2 discomforting, 3 distressing, 4 horrible, 5 excruciating.
