Analysis of Multimodal Psychosomatic Comorbidity Burden in Breast Cancer and Benefit Evaluation of Acupuncture Collaborative Management Regimen

This study adopts a multicenter, pragmatic, umbrella randomized controlled trial design integrated with the shared decision-making (SDM) model. Patients are stratified into four subgroups based on their core psychosomatic symptom phenotypes (single symptom vs. multiple comorbid symptoms). Participants are randomly assigned to the intervention group or control group at a 2:1 allocation ratio. For the intervention group, personalized interventions (including manual acupuncture, auricular point pressing, and combined manual acupuncture plus auricular point pressing) are selected via shared decision-making between clinicians and patients, while the control group receives routine nursing care. The study evaluates the improvement efficacy of single symptoms and the synergistic relief effect of multiple co-occurring symptoms across all psychosomatic phenotype subgroups under the shared decision-making framework. This design addresses the limitation of conventional randomized controlled trials that only focus on individual symptoms, and better fits real-world clinical scenarios characterized by multimorbid coexistence.
