Brief Summary

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.

Detailed 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.

Primary Outcome Measures

Name	Time	Method
Proportion of Patients With Significant Nausea, Rescue Treatment and Number of Times of Vomiting Occurs After chemotherapy (complete protection).	120 hours	The proportion of patients achieving complete protection is defined as patients who have no vomiting, no rescue treatment, no significant nausea that was assessed by visual analog scale (VAS, this is a Visual Analogue Scale was used to assess the incidence and intensity of nausea daily, a 100-mm horizontal bar containing no marking except for the anchor point at each end: left, no nausea; right, worst nausea. No nausea was defined as a VAS scores \< 5mm, no significant nausea was defined as a VAS scores \< 25mm), and maximum less than 25 mm during the first 120 hours after the initiation of chemotherapy (The definition is different from the complete response in the "Secondary endpoints" section).

Secondary Outcome Measures

Name	Time	Method
Fatigue	120 hours	The proportion of patients with fatigue evaluated by Common Terminology Criteria for adverse events Version 4.0 during 0 to120 hours after the initiation of chemotherapy.
Number of times of no vomiting in the overall stage (0 to 120 hours) after chemotherapy (no vomiting in the overall stage)	120 hours	The proportion of patients who have no vomiting during 0 to 120 hours after the initiation of chemotherapy.
The proportion of no significant nausea (no significant nausea in the overall stage)	120 hours	The proportion of patients who have no significant nausea (VAS# 25 mm) that was assessed by VAS, and maximum less than 25 mm during the first 120 hours after the initiation of chemotherapy.
Diarrhea	120 hours	The proportion of patients with diarrhea evaluated by Common Terminology Criteria for adverse events Version 4.0 during 0 to120 hours after the initiation of chemotherapy.
The proportion of patients who have no vomiting/retching or rescue medications after chemotherapy during 24 to 120 hours (delayed complete response)	120 hours	The proportion of patients achieving delayed complete response is defined as patients who have no vomiting/retching or rescue medications during delayed 24 to 120 hours after the initiation of chemotherapy.
Number of times of no vomiting in the acute stage (0 to 24 hours) after chemotherapy (no vomiting in the acute stage)	24 hours	The proportion of patients who have no vomiting during the acute stage (0 to 24 hours) after the initiation of chemotherapy.
Constipation	120 hours	The proportion of patients with constipation evaluated by Common Terminology Criteria for adverse events Version 4.0 during 0 to120 hours after the initiation of chemotherapy.
The relationship between single nucleotide polymorphism genotypes and the proportion of patients with significant nausea, rescue treatment and number of times of vomiting occurs after chemotherapy (complete protection).	120 hours	The single nucleotide polymorphism genotypes will be analyzed by detecting different bases (A, T, C and G) in peripheral blood DNA. The proportion of patients with different single nucleotide polymorphism genotypes will be analyzed. The proportion of patients achieving complete protection is defined as patients who have no vomiting, no rescue treatment, no significant nausea that was assessed by VAS as mentioned above, and maximum less than 25 mm during the first 120 hours after the initiation of chemotherapy. We will analyze the relationship between the proportion of patients with different single nucleotide polymorphism genotypes and the proportion of patients with complete protection.
