Investigating the Role of Hypothalamic Tumor Involvement in Sleep and Cognitive Outcomes Among Children Treated for Craniopharyngioma.

Objective: Despite excellent survival prognosis, children treated for craniopharyngioma experience significant morbidity. We examined the role of hypothalamic involvement (HI) in excessive daytime sleepiness (EDS) and attention regulation in children enrolled on a Phase II trial of limited surgery and proton therapy.

Methods: Participants completed a sleep evaluation (N = 62) and a continuous performance test (CPT) during functional magnetic resonance imaging (fMRI; n = 29) prior to proton therapy.

Results: EDS was identified in 76% of the patients and was significantly related to increased HI extent (p = .04). There was no relationship between CPT performance during fMRI and HI or EDS. Visual examination of group composite fMRI images revealed greater spatial extent of activation in frontal cortical regions in patients with EDS, consistent with a compensatory activation hypothesis.

Conclusion: Routine screening for sleep problems during therapy is indicated for children with craniopharyngioma, to optimize the timing of interventions and reduce long-term morbidity.

Sensitivity and Specificity of the Modified Epworth Sleepiness Scale in Children With Craniopharyngioma.

J Clin Sleep Med 2019 10;15(10):1487-1493

Department of Pediatric Medicine, Division of Nursing Research, St. Jude Children's Research Hospital, Memphis, Tennessee.

Study Objectives: Children with craniopharyngioma are at risk for excessive daytime sleepiness (EDS). Multiple Sleep Latency Testing (MSLT) is the gold standard for objective evaluation of EDS; however, it is time and resource intensive. We compared the reliability, sensitivity, and specificity of the modified Epworth Sleepiness Scale (M-ESS) and MSLT in monitoring EDS in children with craniopharyngioma. Read More

Outcome of craniopharyngioma in children: long-term complications and quality of life.

Division of Neurology, University Children's Hospital of Zurich, Switzerland.

Childhood craniopharyngiomas are histologically benign tumours arising from remnants of Rathke's pouch in the hypothalamic-pituitary region. The two common treatment approaches are primary total resection or limited resection followed by radiotherapy. To study the outcome after a primary surgical approach, we followed 25 consecutive patients (10 females, 15 males) under 16 years of age who were treated in a single institution with a management policy of radical tumour excision (mean age at diagnosis 9 years 2 months, SD 4 years 3 months; range 2 years 9 months to 15 years 11 months).

Objective: Childhood craniopharyngiomas (CP) are often diagnosed after a long duration of history (DOH). Tumor size, hypothalamic involvement (HI), and obesity are associated with reduced overall survival (OS) and functional capacity (FC). The effect of DOH and specific symptoms in history on presentation at initial diagnosis and long-term prognosis are unknown. Read More

Unlabelled: An 11-year old girl with multihormonal pituitary deficiency previously cured from craniopharyngioma was admitted to the endocrinology Department because of pathological daytime sleepiness. At the age of 7 she had undergone brain tumor surgery with adjuvant radiotherapy (complete dose of 5400 cGy). She had been given replacement therapy of thyroid hormone, cortisol and adiuretin.
