NCT06281145

Brief Summary

The goal of this interventional study is to test the heart-rate variability biofeedback intervention (HRV BI) in 2 cohorts of patients. Cohort A will evaluate the effect of the addition of HRV BI in patients with breast cancer treated in the neoadjuvant setting (vs. standard of care alone, SOC) followed by local therapy (surgery +/-radiotherapy). Cohort B will evaluate the effect of the addition of HRV BI in patients with colon cancer after surgery in the adjuvant setting (vs. standard of care alone, SOC).

Outcome Measures

Primary Outcomes (7)

  • Primary endpoint - inflammation

    he effect of 3-month heart rate variability (HRV) biofeedback training and conventional cancer treatment (standard of care, SOC) vs. SOC alone on inflammation (IL-6, Tumor necrosis factor α, IL-10 from peripheral blood sample in pg/ml and tumour infiltrating lymphocytes (TIL) in %).

    36 months

  • Primary endpoint - QoL

    Effect of HRV biofeedback training on quality of life (HRV biofeedback + SOC, vs. The effect of 3-month heart rate variability (HRV) biofeedback training and conventional cancer treatment (standard of care, SOC) vs. SOC alone on EORTC-QLQ-C30 (version 3) score (QLQ- Quality Life Questionnaire). The EORTC-QLQ-C30 has 30 items divided into five functional scales (physical, role, cognitive, emotional, and social), and three symptom scales (fatigue, pain, and nausea and vomiting). The score for each scale as well as the sum score for the whole instrument is standardized to values 0 to 100, with a higher score meaning a worse outcome.

    36 months

  • Primary endpoint - executive functions

    Effect of HRV biofeedback training on executive functions (HRV biofeedback + SOC, vs. SOC alone) measured by Stroop task mean response time for color-word condition.

    36 months

  • Primary endpoint- salivary cortisol slopes

    The effect of 3-month heart rate variability (HRV) biofeedback training and conventional cancer treatment (standard of care, SOC) vs. SOC alone on salivary cortisol slopes (difference between bedtime and awakening saliva cortisol concentration in ng/ml).

    36 months

  • Primary endpoint- sleep quality

    The effect of 3-month heart rate variability (HRV) biofeedback training and conventional cancer treatment (standard of care, SOC) vs. SOC alone on sleep quality measured by both actigraphy and self-report data. The main variables are total time spent sleeping (in hours and minutes), and sleep efficiency (proportion of time spent sleeping vs. time spent in bed trying to sleep).

    36 months

  • Primary endpoint - heart rate variability (HRV)

    Effect of HRV biofeedback training on HRV indexed by the root mean square of successive differences between heartbeats (RMSSD) in ms.

    36 months

  • Primary endpoint - Working memory

    The effect of 3-month heart rate variability (HRV) biofeedback training and conventional cancer treatment (standard of care, SOC) vs. SOC alone on working memory measured by digit span test score (the number of remembered digits in the longest passed sequence), for both forward and backward condition.

    36 months

Secondary Outcomes (4)

  • Secondary endpoint - Pathologic Complete Response (pCR) and Residual Cancer Burden (RCB) rate in cohort A

    36 months

  • Secondary endpoint - Relapse-free Survival (RFS)

    60 months

  • Secondary endpoint - Overall survival (OS)

    96 months

  • Secondary endpoint - Serious Adverse Events (SAE)

    36 months

Study Arms (2)

Standard of care + HRV biofeedback intervention

EXPERIMENTAL

Experimental: Heart-rate variability (HRV) biofeedback intervention + standard of care Deep paced breathing with the HRV monitoring performed three times a day for seven minutes during three months with standard of care. Cohort A- breast cancer, Cohort B- colon cancer

Behavioral: Heart-rate variability biofeedback intervention

Standard of care

NO INTERVENTION

Cohort A- neoadjuvant chemotherapy +/- targeted therapy +/- immunotherapy defined standard of care in current European Society For Medical Oncology (ESMO) guideline in the defined disease subtype Cohort B- adjuvant chemotherapy +/- targeted therapy +/- immunotherapy defined standard of care in current ESMO guideline in the defined disease subtype

Interventions

Daily deep paced breathing 3-times (minimum 7 minutes each) for 3 months

Standard of care + HRV biofeedback intervention
