Auricular Acupressure for Perioperative Anxiety and Pain in Therapeutic Breast Surgery (ROSA) (ROSA)

February 13, 2026 updated by: Marcela Winkler, MD, Robert Bosch Gesellschaft für Medizinische Forschung mbH (RBMF)

Auricular Acupressure for Reducing Perioperative Anxiety and Pain in Therapeutic Breast Surgery Following an Initial Breast Cancer Diagnosis

This randomized, controlled, single-center trial investigates the effects of auricular acupressure, administered according to the National Acupuncture Detoxification Association (NADA) protocol, on perioperative anxiety and pain in patients with a first diagnosis of breast cancer undergoing therapeutic breast surgery. Participants receiving auricular acupressure according to the NADA protocol will be compared with patients receiving standard care alone.

Intervention / Treatment

Detailed Description

Participant recruitment is conducted directly through the clinical department Naturopathy and integrative medicine in the Rober-Bosch-Hospital . During routine care, the study physician informs eligible patients about the study and provides the patient information sheet upon initial interest. The physician subsequently conducts a comprehensive informed-consent discussion and addresses all patient questions. Written consent is obtained only after this process. Participation is voluntary and may be withdrawn at any time without consequences for the patient.

Patients will complete validated instruments measuring anxiety and pain. Participants randomized to the intervention group (auriculotherapy) will receive the treatment during their hospitalization and will be compared with a control group receiving standard care.

Six questions were answered using a five-point Likert scale ranging from 1 (not anxious at all) to 5 (extremely anxious).

Depression
Time Frame: Before the operation
Beck Depression Inventory (BDI) Scores range between 0 and 63, with higher scores representing more severe depression symptoms.

Measure Description
Time Frame
Safety evaluation
Time Frame: Ten Days after the operation

To assess safety, participants will be asked whether they experienced any adverse events (AEs) during the intervention period. All reported AEs will be documented and classified by type and severity according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.

The outcome will be the number of participants with at least one treatment-related adverse event recorded from baseline throgh the end of the intervention.

Ten Days after the operation
Infection
Time Frame: Ten days after the operation
Cases of infection in the surgical area requiring antibiotic treatment will be recorded as either "Yes" or "No". This data will be extracted from the patient's medical records.
Ten days after the operation
Postoperative bleeding
Time Frame: Ten days after the operation
Cases of postoperative bleeding will be recorded as either 'yes' or 'no'. This information will be extracted from the patients' medical records.
