Characterizing Sleep Among Long-term Survivors of Childhood Cancer

April 21, 2026 updated by: St. Jude Children's Research Hospital

The patients are being asked to take part in this clinical trial because they received cancer treatment as a child at St. Jude. The study comprehensively examines sleep among three distinct diagnostic groups of survivors in the SJLIFE cohort: ALL, CNS tumors, and non-CNS solid tumors.

Primary Objective

The primary aim of this protocol is to estimate the prevalence of various sleep disorders among long-term survivors of childhood ALL, CNS tumors, and non- CNS solid tumors.

Exploratory Objective

The exploratory objective of the study is to explore associations between the prevalence of sleep disorders and clinical outcomes collected in SJLIFE.

Study Overview

Detailed Description

A cross-sectional pilot study that will enroll participants for on-campus or remote study activities. The investigators anticipate a targeted evaluable accrual of 120, 40 within each of the three groups identified above. The plan is to employ remote polysomnography and surveys to assess patterns of sleep disorders. These assessments could be done in the homes of survivors or during campus visits.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Insomnia Severity Index (ISI)
Time Frame: Baseline
ISI is a seven-item questionnaire that looks at symptoms of clinical insomnia. The ISI assesses insomnia symptoms over the past 14 days and has demonstrated good reliability and validity. The total ISI score ranges from 0 to 28, with scores < 8 indicating no significant insomnia.
Baseline
CSALTS Sleep Survey
Time Frame: Baseline
CSALTS Sleep Survey incorporating Epworth Sleepiness Scale (EPS) and Pittsburg Sleep Quality Index (PSQI) The CSALTS Sleep Survey assesses sleep quality, patterns, and daytime sleepiness. It incorporates 19 questions from the PSQI and 8 questions of the ESS. The PSQI and ESS total scores will be reported.
Baseline
Morningness-Eveningness Questionnaire (MEQ)
Time Frame: Baseline
The MEQ is a 19-question measure that assesses the degree to which respondents are active and alert at certain times of the day. Each item is rated using a Likert-type scale with lower scales reflecting a more evening-type characterization of alertness. Global scores range from 16 to 86 and these values are used to define 'definitely morning type' (70-86), 'moderately morning type' (59-69), 'neither type' (42-58), 'moderately evening type' (31-41), and 'definitely evening type' (16-30).
Baseline
Circadian Type Inventory (CTI)
Time Frame: Baseline
CTI is an 11-item questionnaire that looks at rigidity/flexibility of sleeping habits and ability/inability to overcome drowsiness (i.e., circadian rhythm disorders). Respondents use a 5-item, Likert-type scale to answer questions regarding their sleep habits and preferences. Scales range from 1 ("almost never") to 5 ("almost always"). Higher scores on the rigidity subscales indicate a greater flexibility in circadian rhythm, while lower scores on the overcoming-drowsiness subscale indicate a greater ability to manage on less sleep.
Baseline
Functional Assessment of Chronic Illness Therapy Fatigue Scale (FACIT)
Time Frame: Baseline
fatigue scale is a short 13-item tool that provides a single measure of an individual's level of fatigue during a usual day.
Baseline
CSALTS Pain Survey
Time Frame: Baseline for 2 nights
The 7-item pain survey will include pain interference questions from the SJLIFE Behavioral Survey and one pain intensity question. The six items that measures amount of pain interference in daily activities in last 7 days is measured from "not at all" to "very much." The pain intensity question is measured 1-10 with 10 "worst imaginable pain."
Baseline for 2 nights
Polysomnography Evaluation (Sleep Profiler PSG2 or WatchPAT)
Time Frame: Baseline

The Sleep Profiler PSG2 measures brain waves during sleep, blood oxygen levels, heart rate, and breathing and will measure different patterns of sleep stages. Two nights of data collection will be requested though one night will be sufficient if the participant sleeps at least 4 hours. The apnea hypopnea index and sleep efficiency scores will be reported.

The WatchPAT device assesses sleep timing, sleep staging, and sleep apnea events via a device worn on the wrist that measures limb movement, peripheral arterial tone and connects to an EKG electrode. Two nights of data collection will be requested though one night will be sufficient if the participant sleeps at least 4 hours. The apnea hypopnea index and sleep efficiency scores will be reported

Baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Sustained Attention -Conners Continuous Performance Test 3rd Ed or CNS-VS CPT.
Time Frame: Baseline
Computerized test of omissions, variability, and reaction time, requiring participants to respond to letter stimuli on the screen quickly and accurately, while avoiding targets. These three scores will be reported in T scores.
Baseline
Memory-California Verbal Learning Test 2nd Ed.
Time Frame: Baseline
Orally administered test of verbal learning, short-term and long-term verbal free-recall memory, requiring participant to learn and remember a list of words, measured in T-score and z-scores.
Baseline
Executive Functions -Trail Making Test or CNS-VS Shifting Attention Test
Time Frame: Baseline

The Trail Making Test is a timed task that requires a participant to shift his/her attention adaptively and flexibly. Considered a measure of cognitive flexibility. Standard score for Trail Making Letter-Word Switching will be reported.

Shifting Attention Test (SAT) measure cognitive flexibility with a single standard score.

Baseline
Executive Functions- Verbal Fluency Test Controlled Oral Word Association (COWA) or CNS-VS Stroop Test
Time Frame: Baseline

This is a task of cognitive/verbal fluency. Participants are given a letter and must say as many words that start with that letter within 60 seconds. A single age-adjusted z-score will be reported.

Stroop Test (ST) measures cognitive control and fluency with a single standard score

Baseline
Executive Functions -Digit Span Backward
Time Frame: Baseline
Digit Span Backward: Digit Span Backward (DSB), from the Digit Span subtest on the WAIS-IV, is a measure of working memory. The number of digits recalled in the longest span is converted to a standard score using age-based norms. Considered a process score on the WAIS-IV DSB is found to have acceptable reliability and validity parameters.
Baseline

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Intelligence
Time Frame: Baseline
WASI-II assessment of intelligence that provides composite scores that estimate verbal comprehension and perceptual reasoning abilities, requiring participants to define words and complete visual puzzles, measured in T scores converted to Standard Scores for Full Scale IQ.
Baseline
Processing Speed - Coding/Digit Symbol or CNS-VS Symbol Digit Test
Time Frame: Baseline
Written timed test of processing speed, requiring participant to copy abstract symbols matched with numbers, measured in a single scaled score
Baseline
Processing Speed-Grooved Pegboard
Time Frame: Baseline
Timed test of fine motor dexterity and speed, requiring participant to put small metal pegs into pegboard, using dominant hand, measured in a single standard score.
Baseline
Pulmonary Function
Time Frame: Baseline
Participants will complete pulmonary function tests (PFTs) as part of their standard on-campus SJLIFE visit. PFTs will be performed in a single laboratory according to the American Thoracic Society task force guidelines. PFTs will include spirometry, lung volume measurements by body plethysmography and single breath carbon monoxide-diffusion capacity (DLCO). The observed values of each survivor for forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), total lung capacity (TLC), and DLCOcorr will be compared with those predicted for the patient's age, race, gender, and height based on reference equations.
Baseline
Echocardiogram
Time Frame: Baseline
Participants will complete an echocardiogram as part of their standard SJLIFE visit. All echocardiograms will be performed using a General Electric VIVID-7. The LV volume, mass and EF will be calculated using the recommendations of the American Society of Echocardiography.
