The Role of Circadian Rhythms in Cancer-Related Symptoms

Emerging evidence indicates that circadian rhythms may be disrupted following cancer and its treatment, and that circadian rhythm disruption may be an underlying pathophysiological mechanism of cancer- and cancer treatment-related symptoms (CRS) such as fatigue, sleep disturbance, cognitive impairment, and depressed mood. Given the detrimental effect of CRS on cancer survivors' quality of life, and a pressing demand for effective interventions to treat CRS, there is a need for a comprehensive examination of circadian disruption related to cancer and its treatment, and its association with CRS. The study will prospectively examine circadian rhythms and a CRS composite score in recently diagnosed breast cancer patients from prior to surgery or chemotherapy to 12 months later. A matched healthy control group will serve as a comparison.

Key information

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients with early breast cancer scheduled for surgery and chemotherapy (neoadjuvant or adjuvant) at Aarhus University Hospital (AUH).
  • The healthy control group will consist of an age-matched sample of participants with no history of cancer.

Exclusion criteria

  • Pregnancy
  • Shift-work
  • Melatonin supplementation
  • Insufficient Danish proficiency
  • Previous cancer diagnosis except for treated non-melanoma skin cancer
  • Confounding diagnosed or suspected psychiatric or medical conditions that might significantly contribute to the CRS or symptoms/diagnoses resembling them (other than those caused by cancer or its treatment) such as seasonal affective disorder.
