Evaluation of the Safety of Percutaneous Sensory Nerve Stimulation in Patients with Head and Neck Cancer Receiving Chemoradiotherapy

Chemoradiotherapy (CRT) is the standard treatment for locally advanced head and neck cancer; however, CRT may cause post-treatment dysphagia. Transcutaneous electrical sensory stimulation (TESS), developed in recent years swallowing rehabilitation, used at many medical facilities. Although TESS has been dysphagia several fields, its safety efficacy patients with cancer remain to be clarified. Therefore, this study evaluated of ten cancers undergoing CRT. Swallowing rehabilitation intervention implementation were performed all during Non-blood-toxicity adverse events (AEs), such as dermatitis mucositis, occurred CRT; severity was less than grade 3. No patient experienced pain due TESS. As survival time analysis using Kaplan–Meier method interferential current device rates revealed a feasibility 100% up 60 Gy 78% 70 Gy, feasible until Gy. This confirmed region precise mechanism on remains unclear, continued use great potential improving disturbance.
