Auricular Point Stimulation Plus Dexamethasone Versus Standard Antiemetic Regimen for Nausea and Vomiting Caused by Trastuzumab Deruxtecan

This study aims to evaluate whether the preventive and suppressive effects of auricular point stimulation combined with dexamethasone on nausea and vomiting induced by trastuzumab deruxtecan are non-inferior to the standard antiemetic regimen in breast cancer palliative therapy. Additionally, it will assess patients' appetite, gastrointestinal function, and other related indicators, and explore the significant role of integrated traditional Chinese medicine and Western medicine interventions in improving patients' quality of life during anti-cancer treatment, thereby providing a clinical reference for optimizing the management of adverse reactions of trastuzumab deruxtecan treatment. The main questions it aims to answer are: Whether the preventive and suppressive effects of auricular point stimulation combined with dexamethasone on nausea and vomiting induced by trastuzumab deruxtecan are non-inferior to the standard antiemetic regimen? In comparison with a standard pharmacologic antiemetic regimen, does auricular point stimulation plus dexamethasone effectively reduce the incidence of appetite loss, weakened or disordered gastrointestinal function, and other uncomfortable conditions? Breast cancer patients receiving palliative treatment with trastuzumab deruxtecan will be randomly assigned in a 1:1 ratio to either the auricular point stimulation group or the standard pharmacologic antiemetic regimen group. Patients in the auricular point stimulation group will: Receive auricular acupressure with bean seeds on specific points of one ear, plus intravenous injection of dexamethasone as a preventive antiemetic treatment within half an hour before trastuzumab deruxtecan injection. Starting from the day of trastuzumab deruxtecan injection (Day 1) to the following five days (Day 1-Day 5), provide regular stimulation at the acupressure points daily by themselves according to the protocol provided in this trial. Record their nausea and vomiting status, appetite, and gastrointestinal function-related symptomatic indicators from Day 1 to Day 5. Oral antiemetics are also prepared. If nausea and vomiting are significant or the patient feels the need, they may be temporarily administered as an adjunct. Patients in the standard pharmacologic antiemetic regimen group will: Receive the standard pharmacologic antiemetic regimen chosen by their physicians according to clinical guidelines.

Auricular Point Stimulation Plus Dexamethasone for Nausea and Vomiting Caused by Trastuzumab Deruxtecan

The goal of this clinical trial is to learn if auricular point stimulation plus dexamethasone works to effectively prevent or suppress nausea and vomiting caused by trastuzumab deruxtecan in breast cancer palliative therapy. It will also learn about the safety and influence on gastrointestinal function of auricular point stimulation plus dexamethasone. The main questions it aims to answer are: Can auricular point stimulation plus dexamethasone effectively prevent or suppress nausea and vomiting induced by trastuzumab deruxtecan? Can auricular point stimulation plus dexamethasone effectively reduce the incidence of appetite loss, weakened or disordered gastrointestinal function, and other uncomfortable conditions caused by excessive use of antiemetic drugs? Participants will: Receive auricular acupressure with bean seeds on specific points of one ear, plus intravenous injection of dexamethasone as a preventive antiemetic treatment within half an hour before trastuzumab deruxtecan treatment. Starting from the day of trastuzumab deruxtecan treatment (Day 1) to the following five days (Day 1-Day 5), provide regular stimulation at the acupressure points daily by themselves according to the protocol provided in this trial. Record their nausea and vomiting status, appetite, and gastrointestinal function-related symptomatic indicators from Day 1 to Day 5. Oral antiemetics are also prepared. If nausea and vomiting are significant or the patient feels the need, they may be temporarily administered as an adjunct.
