ABSTRACT
OBJECTIVES: Insomnia and sleep disorders are common and can be severe amongst patients with cancer, especially during chemotherapy. The aim of this study was to evaluate the efficacy of lettuce seed syrup in breast cancer patients who suffer from insomnia or disordered sleep.
METHODS: This pilot study was a double-blinded randomized controlled clinical trial conducted in Shoha–e-Tajrish Hospital (Tehran, Iran) from September 2018 to June 2019. 50 adult patients with breast cancer with insomnia or sleep disorders were enrolled. Participants were randomly allocated to lettuce seed syrup (5 mL twice daily), or placebo syrup at the same dose for four weeks. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality before and after the intervention.
RESULTS: Compared to placebo, the mean of the total PSQI score decreased significantly in participants who received lettuce seed syrup (p=0.014). In addition, there were statistically significant reductions in the mean scores of subject quality sleep (p=0.002), sleep duration (p=0.038), habitual sleep efficacy (p=0.029) and sleep disturbance (p=0.032) in patients who received lettuce seed syrup.
CONCLUSIONS: Lettuce seed syrup may improve self-reported sleep quality in participants with breast cancer. Larger trials are indicated in diverse samples of participants with caner to learn if these finds are generalizable.
