- Brief Summary
To evaluate the feasibility of a three-parallel-arm, placebo-controlled randomized trial using a standard auricular acupressure protocol for managing nausea and vomiting in a homogenous group of female breast cancer patients undergoing chemotherapy.
The null hypotheses of this study are: (1) There will be no significant difference in acute/delayed nausea and vomiting among groups during the intervention period; (2) There will be no significant difference in anticipatory nausea and vomiting among groups before the second cycle of chemotherapy; (3) There will be no significant difference in quality of life status among groups at the end of the first cycle of chemotherapy.
- Detailed Description
Chemotherapy-induced nausea and vomiting (CINV) is one of the most common and distressing side-effects among cancer patients undergoing chemotherapy. Despite steady progresses in antiemetic prophylaxis and treatment during the past decades, approximately half of cancer patients receiving moderately to highly emetogenic chemotherapy still experience significant nausea and vomiting. Considering the facts that CINV is difficult to be completely controlled by antiemetics along, healthcare professionals has explored the role of non-pharmacological interventions as adjunctive therapy for controlling CINV. Among which, auricular therapy (AT) is a promising approach but the evidence has still not been concluded.
The aim of this study is to test the feasibility of a randomized controlled trial using auricular acupressure protocol for managing nausea and vomiting in female breast cancer patients undergoing chemotherapy. The objectives of this study will be: (1) to pilot the methodological procedure of the randomized controlled trial using a standard auricular acupressure protocol for controlling CINV; (2) to determine the recruitment rate and attrition rate during the whole study period; (3) to determine the feasibility of the study questionnaires and auricular acupressure protocol to the study participants; (4) to identify potential adverse events associated with auricular acupressure; (5) to preliminarily examine the effects of auricular acupressure on CINV and QoL in female breast cancer patients receiving chemotherapy; (6) to explore patients' experience in completing the trial and receiving the intervention; and (7) to refine the study protocol for a future multicenter, large-scale randomized controlled trial.
A three-parallel-arm, placebo-controlled randomized pilot study will be adopted. One hundred and fourteen breast cancer patients scheduled to receive the first cycle of chemotherapy will be recruited from three provincial hospitals in Fuzhou, China, and will be randomly assigned to one of the three groups: the true AT group, the sham AT group or the standard care group. Participants in the true AT group will receive standard anti-emetic medications plus a 5-day auricular acupressure at the specific ear acupoints, participants in the sham AT group will receive standard anti-emetic medications plus a 5-day auricular acupressure at the same acupoints as in the true AT group without any acupoint stimulation, while participants in the standard care group will only be provided with the standard anti-emetic medications. The feasibility outcomes will be the recruitment rate and consent rate during the recruitment stage, the attrition rate during the whole study period, feasibility of the study questionnaires and auricular acupressure protocol to the study participants, and AT-related adverse events. The future main study outcomes will also be measured including acuteCINV, delayed CINV, anticipatory CINV, and quality of life. After completing the pilot clinical trial, a nested qualitative interview will be conducted to explore participants' experience in completing the trial and receiving the intervention.
