Improving radiation therapy for left-sided breast cancer with breathing and relaxation techniques

Respiratory Training and Relaxation Techniques to Improve Adjuvant Radiation Therapy in DIBH in Breast Cancer Patients - B-REST-Study

Not applicable Interventional Technical University of Munich · NCT05975190

This study is testing whether breathing and relaxation techniques can help women with left-sided breast cancer during radiation therapy to protect their heart and improve their overall experience.

What this trial studies

This clinical trial aims to enhance patient compliance and performance during deep inspiration breath hold (DIBH) in women undergoing adjuvant radiotherapy for left-sided breast cancer. It involves a pre-treatment program that combines respiratory training and relaxation techniques to reduce cardiac exposure to radiation. Participants will be randomly assigned to either receive the training or standard care, with the goal of assessing the impact on heart dose and overall patient quality of life. The study seeks to address the challenges of minimizing heart dose during radiotherapy while improving patient satisfaction and cooperation.

Who should consider this trial

Good fit: Ideal candidates are female patients with left-sided breast cancer who have undergone surgery and are scheduled for adjuvant radiotherapy.

Not a fit: Patients with metastatic breast cancer, severe lung disease, or those who have had previous thoracic radiation may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce cardiac risks associated with radiation therapy in breast cancer patients.

How similar studies have performed: Other studies have shown promising results with similar respiratory training techniques in reducing radiation exposure, indicating potential for success in this approach.
