Brief 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.

Design outcomes

Primary

MeasureTime frameDescription
Percentage of patients with significant nausea after the first chemotherapy cycle2 to 3 weeksNausea severity is graded daily from Day 1 (day of chemotherapy) to Day 5, using a numeric scale from 0 to 10. It is a patient reported outcome, patients using a diary. Significant nausea is a score of 2 or more.

Secondary

MeasureTime frameDescription
Percentage of patients with significant nausea after the second and the third chemotherapy cycle.7 to 12 weeksSame measurement at the second and the third chemotherapy. And global score considering the three cycles together.
Percentage of patients that did not vomit or use rescue emesis medication, from the first cycle of chemotherapy to day 5 after the third chemotherapy cycle.7 to 12 weeksPercentage of patients without any vomiting, or rescue emesis medication use, from first to third chemotherapy
Percentage of non planned visit to emergency care unit or general practioner or oncologist due to emesis, measured for the three first chemotherapy cycles.7 to 12 weeksTo measure complication due to emesis from the first cycle of chemotherapy to day 5 after the third chemotherapy cycle
Percentage of non anticipated hydratation with IV fluids measured for the three first chemotherapy cycles.7 to 12 weeksTo measure complication due to emesis from the first cycle of chemotherapy to day 5 after the third chemotherapy cycle
Percentage of hospitalisations for emesis measured for the three first chemotherapy cycles.7 to 12 weeksTo measure complication due to emesis from the first cycle of chemotherapy to day 5 after the third chemotherapy cycle
quality of life measurement using international validated questionnaire EORTC QLQ-C30 (quality of life questionnaire -C30), EORTC QLQ-BR23 (quality of life questionnaire for breast cancer), completed at the first three cycles9 to 15 weekspatient reported outcome measure, using international validated questionnaires and patient diaries
number and type of side effect during vagal stimulation safety7 to 12 weeksreport of any side effect, based on patient declaration
