Personalized Electroacupuncture Treatment for Chemotherapy-induced Nausea and Vomiting in Breast Cancer (PET)

Affiliated Hospital of Qinghai University234 enrolled

Overview

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.

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.

Interventions

True acupuncture + standard antiemetic treatmentPROCEDURE

Participants will receive electroacupuncture once daily from day 1 to day 4. The acupuncturists will insert needles into the acupoints and manipulate the needles until"de qi"sensation is achieved and reported by the participants. Electrical stimulation will be delivered for 30 minutes at alternating frequencies of 2/10Hz. They will receive fosaprepitant 150 mg intravenous IV + palonosetron 0.25 mg IV + dexamethasone 10 mg IV 30 minutes prior to chemotherapy on Day 1, dexamethasone 8 mg IV on days 2, 3, 4 post chemotherapy.

Sham acupuncture + standard antiemetic treatmentPROCEDURE

The sham acupuncture comprised a core standardized prescription of minimally invasive, shallow needle insertion using thin and short needles at body locations not recognized as true acupuncture points and are deemed to not belong to traditional Chinese meridians and have no therapeutic value. Participants will receive minimal acupuncture treatment without electrical stimulation at the same time as the intervention group.Care was taken to avoid "de qi" sensation. They will receive fosaprepitant 150 mg intravenous IV + palonosetron 0.25 mg IV + dexamethasone 10 mg IV 30 minutes prior to chemotherapy on Day 1, dexamethasone 8 mg IV on days 2, 3, 4 post-chemotherapy(the antiemetic drugs are the same as the true acupuncture group).

Outcomes

Primary Outcomes

Proportion of Patients With Significant Nausea, Rescue Treatment and Number of Times of Vomiting Occurs After chemotherapy (complete protection).

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).

Time frame: 120 hours

Secondary Outcomes

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).

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.

Time frame: 120 hours

The proportion of patients who have no vomiting/retching or rescue medications after chemotherapy during 0 to 24 hours (acute complete response)

The proportion of patients achieving acute complete response is defined as patients who have no vomiting/retching or rescue medications during 0 to 24 hours after the initiation of chemotherapy.
