    Abstract

    Purpose: Quality of life in women receiving adjuvant endocrine therapy for breast cancer (BC) may be impaired by hot flushes and night sweats. The cool pad pillow topper (CPPT) is a commercial product, promoted to improve quality of sleep disrupted by hot flushes. This study aimed to identify if the CPPT reduces severity of sleep disturbance by minimising effects of hot flushes. Methods: This randomised phase II trial, recruited women with BC, on adjuvant endocrine therapy, experiencing hot flushes and insomnia. Participants were randomised (stratified by baseline sleep efficiency score (SES) and menopausal status) to the intervention arm (CPPT + standard care) or control arm (standard care). Participants completed Hospital Anxiety and Depression Scale and Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaires and fortnightly sleep/hot flush diaries (where responses were averaged over 2-week periods). The primary endpoint was change in average SES from ?2 to 0 weeks to 2 to 4 weeks. Results: Seventy-four pre- (68.9  and post-menopausal (31.1  women were recruited. Median age was 49.5 years. Endocrine therapies included tamoxifen (93.2 . Median SES at weeks 2 to 4 improved in both arms but the increase on the intervention arm was almost twice that on the control arm (p¿=¿0.024). There were significantly greater reductions in hot flushes and HADS depression in the intervention arm (p¿=¿0.09 and p¿=¿0.036, respectively). There were no significant differences in FACT-B or HADS anxiety. Conclusion: This study supports the use of the CPPT as an aid to reduce sleep disturbance and the frequency/severity of hot flushes.
