Efficacy of TEAS and Acupressure for Breast Cancer Chemotherapy Adverse Reactions

198 breast cancer patients receiving chemotherapy were randomized into control, transcutaneous electrical acupoint stimulation (TEAS), and acupressure groups for a longitudinal follow-up over four chemotherapy cycles. The dataset, authored by Jiang Yuan and last updated in April 2026, contains results from a clinical trial analyzing the dynamic effects of these non-invasive interventions on symptoms like nausea, vomiting, anxiety, and sleep disorders. Analysis was performed using generalized estimating equations (GEE), intention-to-treat (ITT), and per-protocol set (PPS) methods.

Use Cases

• Compare the efficacy of TEAS versus acupressure for reducing chemotherapy-induced nausea and vomiting based on longitudinal symptom tracking.
• Model the temporal dynamics of anxiety and depression symptoms across chemotherapy cycles based on the described intervention effects.
• Analyze the cumulative therapeutic effect of TEAS on quality of life and sleep quality during mid-to-late chemotherapy stages.
• Evaluate intervention strategies for personalized symptom management in breast cancer patients based on the distinct effect profiles described.

Strengths

• Data from a randomized clinical trial with 198 participants, providing a structured experimental basis.
• Longitudinal design tracking patients over four full chemotherapy cycles, allowing analysis of dynamic effects.
• Analysis includes both intention-to-treat and per-protocol set methodologies, which may enhance robustness.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is 57.2 KB, indicating a very limited scope, likely containing summary results rather than raw patient-level data.
