About

This study aims to evaluate electroacupuncture as an antiemetic treatment compared with sham acupuncture in patients with breast cancer, receiving highly emetogenic chemotherapy (HEC). Moreover, it will analyze the association between single nucleotide polymorphism and the antiemetic outcomes of electroacupuncture.

Full description

This is a parallel-group, triple-blinded (participants, evaluators and statisticians), randomized controlled study that investigates the antiemetic role of electroacupuncture combined with standard antiemetic drugs for patients with breast cancer receiving HEC. Neurokinin-1 receptor antagonists (NK-1RAs), serotonin receptor antagonists [5HT3RA] and dexamethasone will be administered prior to initiation of HEC on Day 1 in both groups. Electroacupuncture or sham acupuncture will be randomly administered to the two groups. Subjects will record all events of emesis and the use of rescue antiemetic medication for nausea and/or vomiting. Blood samples will be collected and be analyzed to whether genetic polymorphisms can be used to predict Electroacupuncture outcomes in patients with breast cancer receiving HEC. Primary and secondary outcomes and adverse events will be evaluated.
