What this trial studies

This interventional study aims to evaluate the effectiveness of heart-rate variability biofeedback intervention (HRV BI) in two cohorts of patients with breast and colon cancer. Cohort A will assess the impact of HRV BI in breast cancer patients undergoing neoadjuvant treatment, while Cohort B will focus on colon cancer patients post-surgery in the adjuvant setting. Participants will receive four training sessions and will practice daily HRV techniques at home for three months. The study will measure outcomes related to inflammation, quality of life, cognitive functions, and treatment results.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with confirmed breast cancer needing neoadjuvant treatment or colon cancer patients post-curative surgery.

Not a fit: Patients with previous chemotherapy or other malignancies, as well as those with certain health conditions, may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could enhance the quality of life and treatment outcomes for patients with breast and colon cancer.

How similar studies have performed: Other studies have shown promising results with similar biofeedback approaches, indicating potential for success in this intervention.
