These symptoms undermine patients\u2019s quality of life and reduce chemotherapy adherence. Two non-invasive Traditional Chinese Medicine (TCM) interventions\u2014transcutaneous electrical acupoint stimulation (TEAS) and acupressure have demonstrated efficacy in alleviating such discomforts, data on their effectiveness and dynamic therapeutic characteristics throughout the full chemotherapy course remain insufficient.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>\n                      198 breast cancer patients receiving chemotherapy were subjected to simple randomization using R4.4.2, and randomly assigned to the control group, TEAS group, and acupressure group for a longitudinal follow-up over four chemotherapy cycles.

Main intervention effect: TEAS significantly improved patients\u2019 quality of life(QOL), while acupressure primarily alleviated psychological symptoms such as anxiety and depression. Interaction effect: The therapeutic effect of TEAS was cumulative, exerting more pronounced benefits in reducing the risk of delayed CINV, improving sleep quality, and relieving delayed nausea during the mid-to-late stages of chemotherapy (cycles 3-4); acupressure achieved optimal anxiety relief in the early stage (cycle 1) and progressively alleviated delayed nausea and enhanced QOL throughout the treatment course.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>TEAS and acupressure exhibit dynamic and distinct effects in mitigating adverse reactions in breast cancer patients undergoing chemotherapy. TEAS is more suitable for the comprehensive improvement of physical symptoms and QOL during the mid-to-late stages of chemotherapy, while acupressure is preferred for early anxiety relief and gradual improvement of psychosomatic symptoms throughout the treatment.
