The Comparative Study on the Efficacy and Safety of Single Acupoint and Matching Acupoints

The Different Effectiveness of Single Acupoint vs Matching Acupoints in Chemotherapy-induced Nausea and Vomiting：A Multicenter, Randomized, Controlled Clinical Trial

The purpose of this study is to clarify whether the matching acupoints are more effective than a single point by electro-acupuncture in the management of chemotherapy-induced nausea and vomiting.

Inclusion Criteria:

1. Be diagnosed as cancer and need to accept chemotherapy
2. The score of Karnofsky ≥70
3. Patients of either gender and age 18 years to 80 years
4. Patients receiving chemotherapy both outpatients and inpatients
5. Patients receiving chemotherapy regime with high risk of causing vomiting: cisplatin ≥60 mg/m2, or joint chemotherapy regime of Anthracyclines (Adriamycin≥ 40 mg/ m2 or epirubicin≥60 mg/m2), Dacarbazine or Carboplatin（area under the curve greater than 5mg/ml/min）
6. Life expectancy > 6 months

Exclusion Criteria:

1. To receive radiotherapy and chemotherapy
2. Gastrointestinal tumors
3. Patients with serious liver disease or abnormal hepatorenal function (Aspartate Aminotransferase, Alanine Aminotransferase , and Total Bilirubin are 3 times more than normal, blood urea nitrogen and Cr are 2 times more than normal)
4. Presence of cardiac pacemaker
5. Inflammatory skin reaction
6. Nausea and/or vomiting resulting from opioids or metabolic imbalance (electrolytic disturbances)
7. Patients unable to provide self-care or communication
8. Nausea and/or vomiting resulting from mechanical risk factors (i.e.,intestinal obstruction)
9. Patients with brain metastases or symptoms of intracranial hypertension
10. Nausea and/or vomiting resulting from other diseases(i.e.,sympathetic cervical dispositions, Meniere's syndrome)
11. Women in pregnant and lactating period
12. Refusal to sign informed consent, rejection of randomization into intervention groups.
