Efficacy and Safety of Non Invasive Vagal Stimulation to Prevent Chemotherapy-induced Nausea

Summary

Despite pharmaceutical innovations, chemotherapy induced nausea is frequent and largely participating to alter our patients quality of life. Non invasive vagal stimulation is approved in other health issues, for example in headache or gastroparesis, with a reported benefit on nausea. This study aims to analyse if a non invasive vagal stimulation could better prevent chemotherapy induced nausea, in addition to standard treatment, in breast cancer patients treated with cyclophosphamide and anthracycline.
