Mindfulness breathing exercises to manage chemotherapy symptoms in breast cancer patients

The Effect of Mindfulness-Based Breathing Exercises on Symptom Control and Salivary Cortisol Levels in Breast Cancer Patients Undergoing Chemotherapy

NA · Firat University · NCT07474337

This project will try mindfulness-based breathing exercises with people who have stage I–III breast cancer and are starting chemotherapy to see if the exercises reduce symptoms and lower stress measured by salivary cortisol.

What this trial studies

This randomized controlled experiment will enroll 72 adults with stage I–III breast cancer receiving their first chemotherapy at the Oncology Department of Fırat University Hospital and randomly assign 36 to a mindfulness-based breathing program and 36 to usual care. The intervention teaches focused breathing exercises intended to increase awareness and reduce physiological and psychological stress, while the control arm receives standard symptom management. Outcomes include patient-reported symptoms using the Edmonton Symptom Assessment Scale and salivary cortisol levels collected at predefined time points. Results will compare symptom trajectories and cortisol changes between the intervention and control groups.

Who should consider this trial

Good fit: Adults (≥18) with stage I–III breast cancer who know their diagnosis, are receiving chemotherapy for the first time, can consent, and have no communication or serious psychiatric impairment are ideal candidates.

Not a fit: Patients with metastatic (stage IV) cancer, concurrent other cancers, significant psychiatric or communication problems, or those unable or unwilling to perform breathing exercises are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, patients could experience better symptom control during chemotherapy and reduced stress levels, which may improve overall quality of life.

How similar studies have performed: Previous studies of mindfulness and breathing techniques in cancer populations have shown modest improvements in symptoms and stress biomarkers, though findings across trials are variable and not definitive.

  * Not having a physical disability that would prevent telephone interviews (hearing, speech),
  * Not having any psychiatric disorder that would impair comprehension and understanding,
  * Patients who have verbally and in writing consented to participate in the study will be included in the research.
