Background:
Professional palliative care for patients with cancer focuses on symptom management.
Methods:
This exploratory, randomized controlled study was conducted to compare the effects of complete home-based heart rate variability biofeedback (HRV-BFB) using an estimation formula for resonance frequency in managing insomnia disorders among patients with cancer.
Results:
Only 28 patients were included from the initial enrollment of 30 patients from two study sites. Results showed that compared to the control group, the HRV-BFB group improved sleep efficiency from 82.0% (standard deviation: 9.1%) to 87.8% (standard deviation: 7.2%) (p < 0.001) and decreased use of sleeping medication from 88.2% (95% confidence interval, 73.6-95.8) to 51.5% (95% confidence interval, 41.8-61.1) (p < 0.001).
Conclusions:
This suggests that complete home-based HRV-BFB using an estimation formula for resonance frequency may be a promising tool for treating insomnia disorders in patients with cancer, potentially improving sleep efficiency and decreasing reliance on sleep medications.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
