An exploratory study of sleep habits in school-aged survivors of retinoblastoma

Objective/Background: Retinoblastoma is an ocular cancer diagnosed in early childhood. Previous research has indicated the impact of cancer treatment on sleep, but little is known about how sleep is impacted among survivors of retinoblastoma. The current study aimed to describe sleep habits of school -age survivors of retinoblastoma, to examine associations between sleep and quality of life, and to examine concordance between parent and child reports of sleep habits.Patients/methods: Sixty-nine survivors of retinoblastoma (Mage = 10.89, SD = 1.07, 50.7% female; 56.5% unilateral disease) and their caregivers participated, providing information on both self-and parent -reported sleep habits, quality of life, and demographic data. Results: Greater sleep concerns than national norms were reported by parents (bedtime resistance (t(58) = 2.69, p = .009), greater sleep onset delay (t(66) = 2.46, p = .017), shorter sleep duration (t(57) = 2.12, p = .038), increased daytime sleepiness (t(53) = 6.45, p= <.001)) and children (sleep location (t(61) = 2.39, p = .02), restless legs syndrome (t(62) =-2.21, p = .03), parasomnias (t(64) =19.19, p=<.001)) . Both children and parents of children who received enucleation endorsed greater sleep concerns across several domains (e.g., electronic use before bed, sleep-disordered breathing). Child-and parent-reported sleep concerns were generally associated with decreased quality of life. Finally, child -and parent-report of sleep habits appeared generally consistent. Conclusions: Survivors of retinoblastoma experience sleep difficulties. As such, assessment and targeted intervention is important to mitigate any effects on quality of life. Future research should examine sleep habits of survivors of retinoblastoma across cultures and developmental periods. (c) 2023 Elsevier B.V. All rights reserved.
