Abstract

The SleepCaRe Trial will assess the efficacy of four non-pharmacological sleep interventions in women undergoing chemotherapy for breast cancer.

Insomnia and fatigue symptoms are prevalent among women receiving chemotherapy for breast cancer.
Cognitive behavioral therapy for insomnia (CBTI) and bright light therapy (BLT) may potentially improve sleep outcomes.
Participants will be randomly assigned to one of four interventions over a 6-week period.
Primary outcomes include insomnia and fatigue, with secondary outcomes assessing quality of life and sleep-related impairments.
Data collection will occur at five time points to evaluate the impact of the interventions.

BACKGROUND: Insomnia and fatigue symptoms are common in breast cancer. Active cancer treatment, such as chemotherapy, appears to be particularly disruptive to sleep. Yet, sleep complaints often go unrecognised and under treated within routine cancer care. The abbreviated delivery of cognitive behavioral therapy for Insomnia (CBTI) and bright light therapy (BLT) may offer accessible and cost-effective sleep treatments in women receiving chemotherapy for breast cancer.

METHODS: The Sleep, Cancer and Rest (SleepCaRe) Trial is a 6-month multicentre, randomized, controlled, 2 × 2 factorial, superiority, parallel group trial. Women receiving cytotoxic chemotherapy for breast cancer at tertiary Australian hospitals will be randomly assigned 1:1:1:1 to one of four, non-pharmacological sleep interventions: (a) Sleep Hygiene and Education (SHE); (b) CBTI; (c) BLT; (d) CBT-I + BLT combined and simultaneously delivered. Each sleep intervention is delivered over 6 weeks, and will comprise an introductory session, a mid-point phone call, and regular emails. The primary (insomnia, fatigue) and secondary (health-related quality of life, rest activity rhythms, sleep-related impairment) outcomes will be assessed via online questionnaires at five time-points: baseline (t0, prior to intervention), mid-point intervention (t2, Week 4), post-intervention (t3, Week 7), 3-months (t4, Week 18), and 6-months follow-up (t5, Week 30).

CONCLUSIONS: This study will report novel data concerning the comparative and combined efficacy of CBT-I and BLT during chemotherapy. Findings will contribute to the development of evidence-based early sleep and fatigue intervention during chemotherapy for breast cancer.
