Reducing Cancer Side-effects With Systematic Light Exposure (LYS)
Přehled studie
Postavení
Intervence / Léčba
Detailní popis
Two independent but similar RCTs with a total of 144 breast cancer patients (Group 1 = 72 high risk patients; Group 2 = 72 low risk breast cancer patients) post-treatment screened for fatigue will be randomized to BWL (36 in each of the two groups) or dim light(DL) (36 in each of the two groups) exposure for 30 minutes/morning for 4 weeks, and assessed before, during, immediately and 3 months after the intervention. Measures include questionnaires, cognitive assessment, actigraphy, blood samples, saliva samples, and magnetic resonance imaging (MRI).
1.1 Aims and hypotheses. Aim 1: To test the efficacy of BWL on fatigue (primary outcome) in breast cancer patients.
Hypothesis 1: Compared with control participants exposed to DL, participants randomized to BWL will report less fatigue immediately and 3 months after the intervention.
Aim 2: To test the efficacy of BWL on cognitive functioning (secondary outcome).
Hypothesis 2: Compared with controls, BWL recipients will show improved cognitive functioning immediately and 3 months after the intervention.
Aim 3: To explore the effects of BWL on chronobiological, biological, and neurophysiological markers.
Hypothesis 3: BWL will be associated with normalized circadian activity rhythms (3a); improved sleep (3b); decreased inflammation (3c); increased cortical and subcortical grey matter density (3d); and increased cortical and subcortical white matter integrity (3e). If hypotheses 1 and/or 2 are confirmed, the mediating effects of the markers will be explored.
