The changing burden of long-term health outcomes in survivors of childhood acute lymphoblastic leukaemia: a retrospective analysis of the St Jude Lifetime Cohort Study. LANCET HAEMATOLOGY 2019; 6:e306-e316. [PMID: 31078468 DOI: 10.1016/s2352-3026(19)30050-x] [Citation(s) in RCA: 81] [Impact Index Per Article: 16.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/03/2019] [Revised: 02/16/2019] [Accepted: 02/19/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND Treatment for childhood acute lymphoblastic leukemia has evolved over the past five decades, with moderation of traditional chemotherapy and radiotherapy and the introduction of targeted immune-based and cellular-based therapies. The affect of these changes on late health outcomes has not been assessed. Using data from the The St Jude Lifetime (SJLIFE) Cohort, we aimed to characterise the magnitude of morbidity and patterns of late health outcomes among survivors of childhood acute lymphoblastic leukaemia treated over time. METHODS The St Jude Lifetime (SJLIFE) Cohort is a retrospective cohort study with prospective follow-up and ongoing data accrual designed to facilitate longitudinal, clinically-based assessment of health outcomes among survivors of paediatric malignancies. 980 survivors included in this analysis were diagnosed with paediatric acute lymphoblastic leukaemia at St Jude Children's Research Hospital (SJCRH) between Aug 28, 1963, and July 19, 2003, were aged 18 years old and older at enrolment, had a minimum follow-up of 10 years after diagnosis, and completed an initial on-campus SJLIFE assessment as of data cutoff (June 30, 2015). 272 community control participants, matched to survivors on 5-year age blocks in each sex, were recruited for comparison. Cumulative chemotherapy and radiation dose exposures and major medical events during and after therapy were retrieved from the medical records of the survivors. History or physical examination, laboratory analysis, physical fitness, and neurocognitive testing were done. Health conditions were graded according to a modified version of the Common Terminology Criteria for Adverse Events. Neurocognitive domains of attention (Trial Making Test Part A and Conner's Continuous Performance Test-II) and executive function (Trail Making Test Part B, Controlled Oral Word Association Test, and Wechsler Adult Intelligence Scale-III Digit Span Test Backward) were measured and age-adjusted Z scores were calculated. Mean cumulative count was used to calculate the age-standardised cumulative burden of health conditions over time. This cohort study is registered at ClinicalTrials.gov, number NCT00760656. FINDINGS 980 survivors of acute lymphoblastic leukaemia (50% women, median age at diagnosis 5 years [IQR 3·1-9·1 years], and median time from diagnosis of 30·0 years [22·7-36·3]) had a median age of 35·8 years (29·4-42·9) at assessment compared with 35·1 years (28·7-42·6) for 272 controls. Survivors had significantly more growth hormone deficiency, hypogonadism, and neuropathy than controls. By age 30 years, survivors of acute lymphoblastic leukaemia had, on average, 5·4 (95% CI 5·1-5·8) grade 1-4 health conditions, including 3·2 (2·9-3·4) grade 2-4 health conditions, compared with 2·0 (CI 1·7-2·2) grade 1-4 and 1·2 (1·03-1·4) grade 2-4 health conditions among controls. The cumulative burden of grade 2-4 health conditions involved multiple organ systems for survivors treated on protocols between 1962-91, but after elimination of cranial radiotherapy for children with acute lymphoblastic leukaemia, conditions now predominately include musculoskeletal and endocrine disorders for survivors on protocols between 1991-2007. INTERPRETATION Although changes in paediatric acute lymphoblastic leukaemia treatment protocols have improved overall survival, the burden of late morbidity remains high for these patients. We show that the pattern of late toxic effects has markedly changed over time, with survivors having a reduction in health conditions that are immediately life-threatening, however, maintaining health status and quality of life for survivors of paediatric acute lymphoblastic leukaemia requires continued medical surveillance, counselling, and lifestyle modifications.

Sleep, emotional distress, and physical health in survivors of childhood cancer: A report from the Childhood Cancer Survivor Study. Psychooncology 2019; 28:903-912. [PMID: 30817058 DOI: 10.1002/pon.5040] [Citation(s) in RCA: 37] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Revised: 02/22/2019] [Accepted: 02/25/2019] [Indexed: 11/07/2022]
Abstract
OBJECTIVE Sleep disorders are associated with psychological and physical health, although reports in long-term survivors of childhood cancer are limited. We characterized the prevalence and risk factors for behaviors consistent with sleep disorders in survivors and examined longitudinal associations with emotional distress and physical health outcomes. METHODS Survivors (n = 1933; median [IQR] age = 35 [30, 41]) and siblings (n = 380; age = 33 [27, 40]) from the Childhood Cancer Survivor Study completed measures of sleep quality, fatigue, and sleepiness. Emotional distress and physical health outcomes were assessed approximately 5 years before and after the sleep survey. Multivariable logistic or modified Poisson regression models examined associations with cancer diagnosis, treatment exposures, and emotional and physical health outcomes. RESULTS Survivors were more likely to report poor sleep efficiency (30.8% vs 24.7%; prevalence ratio [PR] = 1.26; 95% confidence interval, 1.04-1.53), daytime sleepiness (18.7% vs 14.2%; PR = 1.31 [1.01-1.71]), and sleep supplement use (13.5% vs 8.3%; PR = 1.56 [1.09-2.22]) than siblings. Survivors who developed emotional distress were more likely to report poor sleep efficiency (PR = 1.70 [1.40-2.07]), restricted sleep time (PR = 1.35 [1.12-1.62]), fatigue (PR = 2.11 [1.92-2.32]), daytime sleepiness (PR = 2.19 [1.71-2.82]), snoring (PR = 1.85 [1.08-3.16]), and more sleep medication (PR = 2.86 [2.00-4.09]) and supplement use (PR = 1.89[1.33-2.69]). Survivors reporting symptoms of insomnia (PR = 1.46 [1.02-2.08]), fatigue (PR = 1.31 [1.01-1.72]), and using sleep medications (PR = 2.16 [1.13-4.12]) were more likely to develop migraines/headaches. CONCLUSIONS Survivors report more sleep difficulties and efforts to manage sleep than siblings. These sleep behaviors are related to worsening or persistently elevated emotional distress and may result in increased risk for migraines. Behavioral interventions targeting sleep may be important for improving health outcomes.

Abstract
BACKGROUND There are limited data describing fitness and associated health-related quality of life (HRQoL) in survivors of childhood Hodgkin lymphoma (HL). PROCEDURE Fitness was evaluated among 336 adult survivors of childhood-onset HL treated at St. Jude Children's Research Hospital and 327 controls who never had childhood cancer. The controls were frequency matched on age, sex, and race. Associations were examined between chronic disease and fitness and between fitness and HRQoL using a multivariable linear and logistic regression. RESULTS Male survivors had lower endurance (6-min walk [6MW] distance 604.4 ± 7.9 m vs 637.0 ± 7.5 m, P < 0.01), and worse neuropathy (modified Total Neuropathy Score [mTNS] 2.7 ± 0.2 vs 1.4 ± 0.2, P < 0.01) compared to controls. Female survivors had lower endurance (6MW distance 564.5 ± 6.9 m vs 590.6 ± 7.0 m, P < 0.01), quadriceps strength (145.7 ± 4.0 vs 163.4 ± 4.0 N·m per kilogram, P < 0.01), and worse neuropathy (mTNS 3.2 ± 0.2 vs 1.4 ± 0.3, P < 0.01) compared to controls. Moderate, severe/disabling, or life-threatening (grades 2-4) neurological conditions were associated with impaired quadriceps strength (odds ratio [OR] 2.94, 99% confidence interval [CI] 1.24-6.96) and impaired endurance (OR 2.96, 99% CI 1.28-6.69). Cardiovascular (OR 2.36, 99% CI 1.00-5.61) and pulmonary (OR 2.78, 99% CI 1.30-5.94) conditions were associated with impaired endurance. Quadriceps strength (β -6.44 ± 2.01, P < 0.01), endurance (β -4.63 ± 1.54, P < 0.01), and neuropathy (β -4.98 ± 1.14, P < 0.01) were associated with a lower physical component summary on the HRQoL. CONCLUSION Survivors of childhood HL, particularly those with neurological, cardiac, and pulmonary chronic conditions, are at risk for impaired fitness and HRQoL.

Abstract
Background Neurocognitive impairment in survivors of childhood cancer may be associated with direct neurotoxicity, as well as indirect effects of systemic health complications. We evaluated associations among treatment exposures, chronic health conditions, and neurocognitive outcomes in adult survivors of childhood cancer. Methods Participants included 5507 adult survivors of childhood cancer (47.1% male; mean [SD] age = 31.8 [7.6] years at evaluation; 23.1 [4.5] years postdiagnosis) in the Childhood Cancer Survivor Study who completed a self-report measure of neurocognitive function. Cardiac, pulmonary, and endocrine chronic health conditions were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.03). Structural equation modeling was used to examine a priori hypothesized causal pathways among cancer treatment, subsequent chronic health conditions, and neurocognitive outcomes. Multivariable models were used to estimate relative risk for associations of treatments and chronic conditions on neurocognitive function. All statistical tests were two-sided. Results One-third of survivors with a grade 2 or higher chronic condition reported impairments in task efficiency and memory. In addition to direct effects of cranial radiation, path analyses and multivariable models demonstrated direct effects of cardiopulmonary (β = 0.10, P = .002; relative risk [RR] = 1.27, 95% confidence interval [CI] = 1.12 to 1.44) and endocrine (β = 0.07, P = .04; RR = 1.14, 95% CI = 1.02 to 1.28) conditions on impaired task efficiency. We identified similar effects of cardiopulmonary condition on memory (P = .01) and emotional regulation (P = .01). Thoracic radiation was associated with impaired task efficiency (P = .01) and emotional regulation (P = .01) through endocrine morbidity. Conclusions Non-neurotoxic exposures, such as thoracic radiation, can adversely impact survivors' neurocognitive function through chronic conditions. Management of chronic diseases may mitigate neurocognitive outcomes among aging survivors of childhood cancer.

Abstract
PURPOSE Treatment of medulloblastoma has evolved from surgery and radiotherapy to contemporary multimodal regimens. However, the impact on long-term health outcomes remains unknown. METHODS Cumulative incidence of late mortality (5 or more years from diagnosis), subsequent neoplasms (SNs), and chronic health conditions were evaluated in the Childhood Cancer Survivor Study among 5-year survivors of medulloblastoma diagnosed between 1970 and 1999. Outcomes were evaluated by treatment exposure, including historical therapy (craniospinal irradiation [CSI] ≥ 30 Gy, no chemotherapy), high risk (CSI ≥ 30 Gy + chemotherapy), standard risk (CSI < 30 Gy + chemotherapy), and by treatment decade (1970s, 1980s, 1990s). Rate ratios (RRs) and 95% CIs estimated long-term outcomes using multivariable piecewise exponential models. RESULTS Among 1,311 eligible survivors (median age, 29 years [range, 6 to 60 years]; median time from diagnosis, 21 years [range, 5 to 44 years]), the 15-year cumulative incidence rate of all-cause late mortality was 23.2% (diagnosed 1970s) versus 12.8% (1990s; P = .002), with a recurrence-related mortality rate of 17.7% versus 9.6% ( P = .008). Lower late mortality rates as a result of other health-related causes were not observed. Among 997 survivors who completed a baseline survey, the 15-year cumulative incidence of SNs was higher among survivors with multimodal therapy (standard risk, 9.5%; historical, 2.8%; P = .03). Survivors treated in the 1990s had a higher cumulative incidence of severe, disabling, life-threatening, and fatal chronic health conditions (56.5% in 1990s v 39.9% in 1970s; P < .001) and were more likely to develop multiple conditions (RR, 2.89; 95% CI, 1.31 to 6.38). However, survivors of standard-risk therapy were less likely to use special education services than high-risk therapy survivors (RR, 0.84; 95% CI, 0.75 to 0.93). CONCLUSION Historical changes in medulloblastoma therapy that improved 5-year survival have increased the risk for SNs and debilitating health conditions for survivors yet reduced the need for special education services.

Abstract
BACKGROUND Financial hardship among survivors of pediatric cancer has been understudied. We investigated determinants and consequences of financial hardship among adult survivors of childhood cancer. METHODS Financial hardship, determinants, and consequences were examined in 2811 long-term survivors (mean age at evaluation = 31.8 years, years postdiagnosis = 23.6) through the baseline survey and clinical evaluation. Financial hardship was measured by material, psychological, and coping/behavioral domains. Outcomes included health and life insurance affordability, retirement planning, symptoms, and health-related quality of life (HRQOL). Odds ratios (ORs) estimated associations of determinants with financial hardship. Odds ratios and regression coefficients estimated associations of hardship with symptom prevalence and HRQOL, respectively. All statistical tests were two-sided. RESULTS Among participants, 22.4% (95% confidence interval [CI] = 20.8% to 24.0%), 51.1% (95% CI = 49.2% to 52.9%), and 33.0% (95% CI = 31.1% to 34.6%) reported material, psychological, and coping/behavioral hardship, respectively. Risk factors across hardship domains included annual household income of $39 999 or less vs $80 000 or more (material OR = 3.04, 95% CI = 2.08 to 4.46, psychological OR = 3.64, 95% CI = 2.76 to 4.80, and coping/behavioral OR = 4.95, 95% CI = 3.57 to 6.86) and below high school attainment vs college graduate or above (material OR = 2.22, 95% CI = 1.45 to 3.42, psychological OR = 1.75, 95% CI = 1.18 to 2.62, and coping/behavioral OR = 2.05, 95% CI = 1.38 to 3.06). Myocardial infarction, peripheral neuropathy, subsequent neoplasm, seizure, stroke, reproductive disorders, amputation, and upper gastrointestinal disease were associated with higher material hardship (all P < .05). Hardship across three domains was associated with somatization, anxiety and depression (all P < .001), suicidal ideation (all P < .05), and difficulty in retirement planning (all P < .001). Survivors with hardship had statistically significantly lower HRQOL (all P < .001), sensation abnormality (all P < .001), and pulmonary (all P < .05) and cardiac (all P < .05) symptoms. CONCLUSIONS A substantial proportion of adult survivors of childhood cancer experienced financial hardship. Vulnerable sociodemographic status and late effects were associated with hardship. Survivors with financial hardship had an increased risk of symptom prevalence and impaired HRQOL.

Abstract
AIMS To estimate the level of alcohol consumption behaviors in adult survivors of childhood cancer and to test associations between alcohol consumption behaviors and symptoms of neurocognitive impairment and emotional distress. DESIGN Retrospective cohort study with longitudinal follow-up of self-reported health outcomes. SETTING Childhood Cancer Survivor Study (CCSS), a 26-center study of ≥ 5-year survivors of childhood cancer diagnosed ≤ 21 years of age between 1970 and 1986 in the United States and Canada. PARTICIPANTS A total of 4484 adult survivors of childhood cancer [mean (standard deviation) age at evaluation = 34.8 (6.1) years; time from diagnosis = 24.8 (4.4) years] and 1651 sibling controls who completed surveys reporting on alcohol use, neurocognitive impairment and emotional distress. MEASUREMENTS Survivor report of alcohol use included age at drinking initiation and quantity and frequency of alcohol consumption. Neurocognition was assessed using the CCSS Neurocognitive Questionnaire. Emotional distress symptoms were measured using the Brief Symptoms Inventory-18 and the Posttraumatic Stress Diagnostic Scale. FINDINGS After adjustment for childhood cancer treatment exposures, including cranial radiation therapy, drinking initiation prior to 18 years of age was associated with 30% increased risk of subsequent memory problems [risk ratio (RR) = 1.3; 95% confidence interval (CI) = 1.1-1.5]. Younger age at drinking initiation was associated with future risk of depression (RR = 1.3; 95% CI = 1.1-1.5), anxiety (RR = 1.6; 95% CI = 1.3-2.1), and somatization (RR = 1.2; 95% CI = 1.1-1.4). Persistent heavy/risky drinking was associated with 80% increased risk of persistent psychological distress (RR = 1.8, 95% CI = 1.4-2.3). CONCLUSIONS Drinking initiation during adolescence is associated with modest increased risk for memory impairment and emotional distress in adult survivors of childhood cancer.

Effects of Demographic Variables on Subjective Neurocognitive Complaints Using the Neurocognitive Questionnaire (NCQ) in an Aged Japanese Population.

Abstract
OBJECTIVES In an aged Japanese population, we investigated associations of demographic variables with subjective neurocognitive complaints using the Neurocognitive Questionnaire (NCQ). METHODS Participants (N = 649) provided answers to the NCQ in both 2011 and 2013. Using fully-completed NCQs from 503 participants in 2011, we identified latent factors of subjective neurocognitive complaints using exploratory factor analysis; then examined associations of demographic variables with the identified factors for all 649 participants over the two years. We also examined changes in factor scores over the 2-year period. RESULTS We identified four factors representing 20 of the 25 NCQ items and labelled them metacognition, emotional regulation, motivation/organization, and processing speed. In a regression model using all participants, we observed linear deterioration with age on emotional regulation and linear-quadratic deterioration with age on the other factors. Less education was associated with more problems for all factors, but we detected no evidence of interaction between age and education. In 314 participants completing both assessments, paired t-tests comparing the 2013 to 2011 responses corroborated the regression results, except for emotional regulation. CONCLUSIONS On the NCQ, older age and less education were associated with more subjective neurocognitive complaints. This is compatible with the association of the same factors with objective cognition and suggests that subjective cognitive complaints complement objective cognition as a prodrome of non-normative cognitive decline.

Abstract
Background Survivors of childhood central nervous system (CNS) tumors experience high rates of treatment-related neurologic sequelae. Whether survivors continue to be at increased risk for new events as they age is unknown. Methods Adverse neurologic health conditions in 5-year survivors of CNS tumors from the Childhood Cancer Survivor Study (n = 1876) were evaluated longitudinally at a median 23.0 years from diagnosis (range, 5.1-38.9), median age at last evaluation 30.3 years (range, 6.1-56.4). Multivariable regression estimated hazard ratios (HRs) and 95% CIs. Results From 5 to 30 years post diagnosis, cumulative incidence increased for seizures from 27% to 41%, motor impairment 21% to 35%, and hearing loss 9% to 23%. Risks were elevated compared with siblings (eg, seizures HR: 12.7; 95% CI: 9.6-16.7; motor impairment HR: 7.6; 95% CI: 5.8-9.9; hearing loss HR: 18.4; 95% CI: 13.1-25.9). Regional brain doses of radiation therapy were associated with development of new deficits (eg, frontal ≥50 Gy and motor impairment HR: 2.0; 95% CI: 1.2-3.4). Increased risk for motor impairment was also associated with tumor recurrence (HR: 2.6; 95% CI: 1.8-3.8), development of a meningioma (HR: 2.3; 95% CI: 0.9-5.4), and stroke (HR: 14.9; 95% CI: 10.4-21.4). Seizure risk was doubled by recurrence (HR: 2.3; 95% CI: 1.6-3.2), meningioma (HR: 2.6; 95% CI: 1.1-6.5), and stroke (HR: 2.0; 95% CI: 1.1-3.4). Conclusions CNS tumor survivors remain at risk for new-onset adverse neurologic events across their lifespans at a rate greater than siblings. Cranial radiation, stroke, tumor recurrence, and development of meningioma were independently associated with late-onset adverse neurologic sequelae.

Abstract
BACKGROUND The impact of growth hormone deficiency (GHD) on neurocognitive function is poorly understood in survivors of childhood acute lymphoblastic leukemia (ALL). This study examined the contribution of GHD to functional outcomes while adjusting for cranial radiation therapy (CRT). METHODS Adult survivors of ALL (N = 571; 49% female; mean age, 37.4 years; age range, 19.4-62.2 years) completed neurocognitive tests and self-reported neurocognitive symptoms, emotional distress, and quality of life. GHD was defined as a previous diagnosis of GHD or a plasma insulin-like growth factor1 level less than -2.0 standard deviations for sex and age at the time of neurocognitive testing. Hypothyroidism, hypogonadism, sex, age at diagnosis, CRT dose, and intrathecal and high-dose intravenous methotrexate were included as covariates in multivariable linear regression models. RESULTS Of the 571 survivors, 298 (52%) had GHD, and those with GHD received higher doses of CRT (P = .002). Survivors who had GHD, irrespective of prior growth hormone treatment, demonstrated poorer vocabulary (z-score, -0.84 vs -0.61; P = .02), processing speed (z-score, -0.49 vs -0.30; P = .04), cognitive flexibility (z-score, -1.37 vs -0.94; P = .01), and verbal fluency (z-score, -0.74 vs -0.44; P = .001), and they self-reported more neurocognitive problems and poorer quality of life compared with survivors who did not have GHD. Multivariable and mediation models revealed that GHD was associated with small effects on quality of life (general health, P = .01; vitality, P = .01; mental health, P = .01); and CRT dose accounted for the lower neurocognitive outcomes. CONCLUSIONS Adult survivors of childhood ALL who receive CRT are at risk for GHD, although poor neurocognitive outcomes are determined by CRT dose and not by the presence of GHD.

Long-term health and social function in adult survivors of paediatric astrocytoma: A report from the Childhood Cancer Survivor Study. Eur J Cancer 2018; 106:171-180. [PMID: 30528801 DOI: 10.1016/j.ejca.2018.10.016] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2018] [Revised: 09/26/2018] [Accepted: 10/22/2018] [Indexed: 12/16/2022]
Abstract
BACKGROUND Although paediatric astrocytoma has an excellent 5-year survival rate, survivors remain at risk for morbidity and late mortality. This study aimed to estimate the risk of late mortality, chronic conditions, poor health status and social impairment in ageing paediatric astrocytoma survivors. METHODS We longitudinally evaluated 1182 5-year astrocytoma survivors diagnosed between 1970 and 1986 and 4023 siblings enrolled in a retrospective cohort study. Kaplan-Meier estimates of late mortality and cumulative incidence of serious chronic conditions were estimated. Cox regression models provided hazard ratios (HRs) with 95% confidence intervals (CIs) for development of chronic conditions, and generalised linear models provided relative risks (RRs) of the poor health status and social outcomes. RESULTS At 30 years from diagnosis, cumulative late mortality was 22.1% (CI 20.0-24.3%), primarily due to disease progression or recurrence. Compared with siblings, survivors were at increased risk of serious chronic conditions (HR 4.6, CI 3.8-5.5). Survivors reported higher rates of poor general health (RR 3.3, CI 2.8-3.8), poor mental health (RR 1.9, CI 1.7-2.1), functional impairment (RR 9.0, CI 7.7-10.5) and activity limitation (RR 3.6, CI 3.1-4.2) and lower rates of college graduation (RR 0.75, CI 0.69-0.82), marriage (RR 0.62, CI 0.58-0.66), employment (RR 0.75, CI 0.72-0.79) and household income ≥$40,000 (RR 0.68, CI 0.64-0.73). Even survivors without radiation exposure had elevated risk of chronic conditions, poor health status and social impairment compared with siblings. CONCLUSIONS Survivors of paediatric astrocytoma are at high risk for long-term complications of their disease and its treatment. They require lifelong monitoring for late effects.

Abstract
BACKGROUND AND PURPOSE Survivors of acute lymphoblastic leukemia are at risk for neurocognitive deficits and leukoencephalopathy. We performed a longitudinal assessment of leukoencephalopathy and its associations with long-term brain microstructural white matter integrity and neurocognitive outcomes in survivors of childhood acute lymphoblastic leukemia treated on a modern chemotherapy-only protocol. MATERIALS AND METHODS One hundred seventy-three survivors of acute lymphoblastic leukemia (49% female), treated on a chemotherapy-only protocol, underwent brain MR imaging during active therapy and repeat imaging and neurocognitive testing at follow-up (median, 13.5 years of age; interquartile range, 10.7-17.6 years; median time since diagnosis, 7.5 years; interquartile range, 6.3-9.1 years). Persistence of leukoencephalopathy was examined in relation to demographic and treatment data and to brain DTI in major fiber tracts and neurocognitive testing at follow-up. RESULTS Leukoencephalopathy was found in 52 of 173 long-term survivors (30.0%) and persisted in 41 of 52 (78.8%) who developed it during therapy. DTI parameters were associated with leukoencephalopathy in multiple brain regions, including the corona radiata (fractional anisotropy, P = .001; mean diffusivity, P < .001), superior longitudinal fasciculi (fractional anisotropy, P = .02; mean diffusivity, P < .001), and superior fronto-occipital fasciculi (fractional anisotropy, P = .006; mean diffusivity, P < .001). Mean diffusivity was associated with neurocognitive impairment including in the genu of the corpus callosum (P = .04), corona radiata (P = .02), and superior fronto-occipital fasciculi (P = .02). CONCLUSIONS Leukoencephalopathy during active therapy and neurocognitive impairment at long-term follow-up are associated with microstructural white matter integrity. DTI may be more sensitive than standard MR imaging for detection of clinically consequential white matter abnormalities in childhood acute lymphoblastic leukemia survivors treated with chemotherapy and in children undergoing treatment.

Abstract
OBJECTIVE Positive psychological outcomes among adolescent and young adult survivors of childhood cancer may influence long-term health status. We examined posttraumatic growth (PTG) and Life satisfaction (LS) in adolescence, and their impact on future emotional and physical health status in young adulthood. METHODS Survivors (n = 2802) from the Childhood Cancer Survivor Study were longitudinally analyzed across social, emotional, and physical factors during adolescence (12-17 years old), and PTG (PTG-Inventory) and LS (Cantril-Ladder-of-Life) during young adulthood (19-24 years old). The impact of PTG and LS on survivors' future long-term mental health, physical health, and social skills was also examined (23-28 years old) using Structural Equation Modeling. RESULTS Survivors reported high levels of LS (M = 7.43, range 1 to 10) and a positive impact from their cancer experience (M = 48.78, range 0 to 105). Adolescent predictors of higher PTG included older age at diagnosis (p = 0.001), experiencing more severe chronic health conditions (p = 0.01), cancer recurrence/relapse (p = 0.01), and being diagnosed with a non-CNS cancer (p = 0.001). Higher perceived general health (p = 0.01), higher social skills (p = 0.001), and diagnosis with a non-CNS cancer (p = 0.02) were associated with higher LS. Higher PTG during young adulthood predicted poorer perceived health (p = 0.04) and worse emotional health (p = 0.001) in later adulthood. Higher LS predicted better emotional health (p = 0.001) and better perceived health (p = 0.001). CONCLUSIONS While LS was found to help survivors have better perceived long-term emotional and physical health outcomes, survivors with higher PTG fond both positive and negative impacts from cancer. Future therapeutic trials to improve LS should be considered.

Abstract
Purpose Beyond survival, achieving independence is a primary goal for adult survivors of pediatric CNS tumors. However, the prevalence of and risk factors for failure to achieve independence, assessed with multiple concurrent indicators, have not been examined. Patients and Methods Functional and social independence was assessed in 306 survivors (astrocytoma [n = 130], medulloblastoma [n = 77], ependymoma [n = 36], and other [n = 63]; median current age, 25.3 years [range, 18.9 to 53.1 years]; time since diagnosis, 16.8 years [range, 10.6 to 41.8 years]). Six observed indicators were used to identify latent classes of independence, which included employment, living independently, assistance with personal care, assistance with routine needs, obtaining a driver's license, and marital status. Physical performance impairments were defined as scores < 10th percentile on measures of aerobic capacity, strength, flexibility, balance, mobility, and adaptive function. Multinomial logistic regression estimated odds ratios (ORs) and 95% CIs were calculated for associations of disease/treatment exposures and impairments in physical performance with nonindependence. Results Three classes of independence were identified as independent (40%), moderately independent (34%), and nonindependent (26%). In multivariable models, craniospinal irradiation (OR, 4.20; 95% CI, 1.69 to 10.44) and younger age at diagnosis (OR, 1.24; 95% CI, 1.14 to 1.35) were associated with risk of nonindependence versus independence. Beyond impaired IQ, limitations in aerobic capacity (OR, 5.47; 95% CI, 1.78 to 16.76), flexibility (OR, 3.66; 95% CI, 1.11 to 12.03), and adaptive physical function (OR, 11.54; 95% CI, 3.57 to 37.27) were associated with nonindependence versus independence. Nonindependent survivors reported reduced physical but not mental health-related quality of life compared with independent survivors. Conclusion Sixty percent of survivors of pediatric CNS tumors do not achieve complete independence as adults. Reduction in intensity of primary therapies and interventions that target physical performance and adaptive deficits may help survivors to achieve greater independence.

Abstract
BACKGROUND Survivors of childhood cancer report poor health-related quality of life (HRQOL). Modifiable lifestyle factors such as nutrition and physical activity represent opportunities for interventions to improve HRQOL. METHODS The authors examined the association between modifiable lifestyle factors and HRQOL among 2480 adult survivors of childhood cancer in the St. Jude Lifetime Cohort Study. Dietary intake, physical activity, cigarette smoking, and alcohol consumption were assessed through questionnaires. Weight and height were measured in the clinic. HRQOL was evaluated using the Medical Outcome Study 36-Item Short Form Survey. The physical component summary (PCS), mental component summary (MCS), and 8 domain scores of HRQOL were calculated. Multivariable linear regression models were used to estimate regression coefficients (β) associated with HRQOL differences. RESULTS Being physically active (PCS β = 3.10; and MCS β = 1.48) was associated with higher HRQOL whereas current cigarette smoking (PCS β = -2.30; and MCS β = -6.49) and obesity (body mass index ≥30 kg/m2 ) (PCS β = -3.29; and MCS β = -1.61) were associated with lower HRQOL in both the physical and mental domains. Better diet (Healthy Eating Index-2015) was associated with higher physical HRQOL (PCS β = 1.79). Moderate alcohol consumption was associated with higher physical (PCS β = 1.14) but lower mental (MCS β = -1.13) HRQOL (all P <.05). Adherence to multiple healthy lifestyle factors demonstrated a linear trend with high scores in both physical and mental HRQOL (highest vs lowest adherence: PCS β = 7.60; and MCS β = 5.76 [P for trend, <.0001]). CONCLUSIONS The association between healthy lifestyle factors and HRQOL is cumulative, underscoring the importance of promoting multiple healthy lifestyles to enhance HRQOL in long-term survivors of childhood cancer.

Abstract
Chemotherapeutic agents used to treat acute lymphoblastic leukemia (ALL), the most common cancer affecting young children, have been associated with long-term cognitive impairments that reduce quality of life. Executive dysfunction is one of the most consistently observed deficits and can have substantial and pervasive effects on academic success, occupational achievement, psychosocial function, and psychiatric status. We examined the neural mechanisms of executive dysfunction by measuring structural and functional connectomes in 161 long-term survivors of pediatric ALL, age 8-21 years, who were treated on a single contemporary chemotherapy-only protocol for standard/high- or low-risk disease. Lower global efficiency, a measure of information exchange and network integration, of both structural and functional connectomes was found in survivors with executive dysfunction compared with those without dysfunction (p < 0.046). Patients with standard/high- versus low-risk disease and those who received greater number of intrathecal treatments containing methotrexate had the lowest network efficiencies. Patients with executive dysfunction also showed hyperconnectivity in sensorimotor, visual, and auditory-processing regions (p = 0.037) and poor separation between sensorimotor, executive/attention, salience, and default mode networks (p < 0.0001). Connectome disruption was consistent with a pattern of delayed neurodevelopment that may be associated with reduced resilience, adaptability, and flexibility of the brain network. These findings highlight the need for interventions that will prevent or manage cognitive impairment in survivors of pediatric acute lymphoblastic leukemia.

Abstract
BACKGROUND Healthy lifestyle choices, including participation in regular physical activity, may improve health outcomes in survivors of childhood cancer. We aimed to evaluate the efficacy of a web-delivered physical activity intervention among adolescent survivors to increase moderate to vigorous physical activity (MVPA) and improve fitness and neurocognitive and health-related quality of life (HRQoL) over 24 weeks. PROCEDURE This randomized controlled trial was conducted among survivors (aged ≥11 to <15 years) treated at a single institution. Participants were randomized to either a physical activity intervention delivered over the internet or a control group. The intervention group received educational materials, an activity monitor, and access to an interactive website designed to motivate increased physical activity via rewards; the control group received an activity monitor and educational materials. Physical activity, fitness, and neurocognitive and HRQoL outcomes were assessed at baseline and at 24 weeks. Mean changes were compared between groups using paired t-tests. RESULTS Of the 97 survivors enrolled, 78 completed the study; the mean age was 12.7 (standard deviation 1.1), 80% were White, and 55.1% were female. Fifty-three survivors were assigned to the intervention and 25 to the control group. While survivors in the intervention group increased, and those in the control group decreased (4.7 ± 119.9 vs. -24.3 ± 89.7 min) weekly MVPA, this difference was not significant (P = 0.30). However, hand grip strength, number of sit-ups and pushups, neurocognitive function, and HRQoL outcomes improved in the intervention, but not in the control group. CONCLUSIONS An interactive, rewards-based intervention designed to increase MVPA is feasible in adolescent survivors of childhood cancer.

Abstract
PURPOSE To describe and compare the prevalence of mental health access, preference, and use among pediatric cancer survivors and their siblings. To identify factors associated with mental health access and use among survivors. METHODS Six hundred ninety-eight survivors in the Childhood Cancer Survivor Study (median age = 39.4; median years from diagnosis = 30.8) and 210 siblings (median age = 40.4) were surveyed. Outcomes included having mental health insurance coverage, delaying care due to cost, perceived value of mental health benefits, and visiting a mental health provider in the past year. RESULTS There were no differences in mental health access, preferences, and use between survivors and siblings (p > 0.05). Among respondents with a history of distress, most reported not having seen a mental health provider in the past year (80.9% survivors vs. 77.1% siblings; p = 0.60). Uninsured survivors were more likely to defer mental health services due to cost (24.6 vs. 8.4%; p < 0.001). In multivariable models, males (OR = 2.96) and survivors with public (OR = 6.61) or employer-sponsored insurance (ESI; OR = 14.37) were more likely to have mental health coverage. CONCLUSIONS Most childhood cancer survivors value having mental healthcare benefits; however, coverage and use of mental health services remain suboptimal. The most vulnerable of survivors, specifically the uninsured and those with a history of distress, are at risk of experiencing challenges accessing mental health care. IMPLICATIONS FOR CANCER SURVIVORS Childhood cancer survivors are at risk for experiencing high levels of daily life stress that is compounded by treatment-related sequelae. Integrative, system-based approaches that incorporate financial programs with patient education about insurance benefits can help reduce some of the financial barriers survivors face.

Abstract
BACKGROUND The purpose of this study was to examine the prevalence and predictors of social difficulties in adolescent survivors of central nervous system (CNS) tumors. METHODS Six hundred sixty-five survivors of CNS tumors (53.8% male and 51.7% treated with cranial radiation therapy [CRT]), who had a current median age of 15.0 years (range, 2.0-17.0 years) and were a median of 12.1 years (range, 8.0-17.7 years) from their diagnosis, were compared with 1376 survivors of solid tumors (50.4% male), who had a median age of 15.0 years (range, 12.0-17.0 years) and were a median of 13.2 years (range, 8.3-17.9 years) from their diagnosis, and 726 siblings (52.2% male), who had a median age of 15.0 years (range, 12.0-17.0 years). Social adjustment was measured with parent-proxy responses to the Behavior Problems Index. Latent profile analysis defined social classes. Multinomial logistic regression, adjusted for age, sex, and age at diagnosis, identified predictors of class membership. Path analyses tested mediating effects of physical limitations, sensory loss, and cognitive impairment on social outcomes. RESULTS Caregivers reported that survivors of CNS tumors were more likely to have 0 friends (15.3%) and to interact with friends less than once per week (41.0%) in comparison with survivors of solid tumors (2.9% and 13.6%, respectively) and siblings (2.3% and 8.7%, respectively). Latent profile analysis identified 3 social classes for survivors of CNS tumors: well-adjusted (53.4%), social deficits (16.2%), and poor peer relationships (30.4%). However, 2 classes were identified for survivors of solid tumors and siblings: well-adjusted (86.2% and 91.1%, respectively) and social deficits (13.8% and 8.9%, respectively). CRT predicted class membership for CNS survivors (odds ratio [OR] for poor peer relationships, 1.16/10 Gy; 95% confidence interval [CI], 1.08-1.25; OR for social deficits 1.14/10 Gy; 95% CI, 1.04-1.25; reference, well-adjusted). Cognitive impairment mediated the association between all social outcomes and CRT (P values < .001). CONCLUSION Almost 50% of survivors of CNS tumors experience social difficulties; the pattern is unique in comparison with solid tumor and sibling groups. Cognitive impairment is associated with increased risk, and this highlights the need for multitargeted interventions.

Abstract
Importance Little is known about treatment-related neurotoxic mechanisms in children with acute lymphoblastic leukemia (ALL) treated with chemotherapy only. Objective To examine concentration of cerebrospinal fluid (CSF) biomarkers of brain injury at ALL diagnosis and during cancer therapy and to evaluate associations with long-term neurocognitive and neuroimaging outcomes and relevant genetic polymorphisms. Design, Setting, and Participants This prospective cohort study included 235 patients with ALL who received a chemotherapy-only protocol. Patients provided CSF samples after diagnosis and throughout treatment. At 5 or more years after the diagnosis, 138 (69.7%) of 198 eligible survivors participated in long-term follow-up assessments. Children were treated from June 1, 2000, through October 31, 2010. Follow-up was completed on October 21, 2014, and data were analyzed from August 1, 2015, through September 30, 2016. Exposures Plasma concentration of high-dose intravenous methotrexate sodium and number of triple intrathecal chemotherapy injections. Main Outcomes and Measures The CSF samples were assayed at 5 points from diagnosis to reinduction for biomarkers of myelin degradation (myelin basic protein [MBP]), neuronal damage (nerve growth factor [NGF] and total and phosphorylated tau protein), astrogliosis (glial fibrillary acidic protein [GFAP]), and neuroinflammation (chitotriosidase). DNA was genotyped for polymorphisms in drug metabolism, oxidative stress, and neurodevelopment. Leukoencephalopathy was evaluated by brain imaging. At 5 or more years after the diagnosis, survivors completed neurocognitive testing and brain imaging of white matter integrity. Results Among the 235 patients with CSF samples (120 boys [51.1%] and 115 girls [48.9%]; mean [SD] age at diagnosis, 6.8 [4.7] years), MBP and GFAP levels were elevated at baseline and through consolidation. The number of intrathecal injections was positively correlated with NGF level increase at consolidation (r = 0.19; P = .005). Increases in GFAP (risk ratio [RR], 1.23; 95% CI, 1.09-1.40), MBP (RR, 1.06; 95% CI, 1.01-1.11), and total tau (RR, 1.76; 95% CI, 1.11-2.78) levels were associated with a higher risk for leukoencephalopathy and higher apparent diffusion coefficient in frontal lobe white matter 5 years after diagnosis (standardized estimate, 0.05; P < .001). Increase in total tau at consolidation was associated with worse attention (omissions z score estimate, -0.20; P = .04). Conclusions and Relevance Glial injury may be present at diagnosis of ALL. Neuronal injury was associated with intrathecal chemotherapy. The CSF biomarkers may be useful in identifying individuals at risk for worse neurologic outcomes, particularly those with genetic susceptibility to poor brain function.

Abstract
OBJECTIVE How family environment and parental factors affect health status and symptoms in childhood cancer survivors is understudied. We examined the influence of family cohesion, parent distress, and overprotection on child symptom burden and health-related quality of life (HRQOL) and family strain in survivors of childhood acute lymphoblastic leukemia. METHODS Parents of 213 children treated with chemotherapy only completed a survey when survivors were at least 5-year postdiagnosis. Family Environment Scale, Brief Symptom Inventory-18, Parent Protection Scale, Pediatric Quality of Life Inventory, and Impact on Family were used to assess family cohesion, parental distress, overprotection, child symptom burden and HRQOL, and family strain, respectively. Path analysis was conducted to quantify effects of family cohesion on family strain through parental distress, overprotection, child symptoms, and HRQOL. RESULTS Lower family cohesion (β = 0.06, 95% CI, 0.01-0.13), higher parental distress (β = 0.35, 95% CI, 0.20-0.45), and overprotection (β = 0.17, 95% CI, 0.01-0.32) were associated with more child symptom burden. More symptom burden were associated with poorer child HRQOL (β = 0.66, 95% CI, 0.57-0.75), which in turn was associated with more family strain (β = 0.11, 95% CI, 0.01-0.22). Lower maternal education was associated with overprotection (β = -0.23, 95% CI, -0.33 to -0.12), more child symptoms (β = -0.30, 95% CI, -0.41 to -0.16), poorer child HRQOL (β = -0.36, 95% CI, -0.46 to -0.21), and more family strain (β = -0.15, 95% CI, -0.23 to -0.08). CONCLUSIONS Family and parental factors contributed to health outcomes of childhood acute lymphoblastic leukemia survivors. Interventions to enhance family cohesion, decrease parental distress and overprotection, and ameliorate child symptoms may improve family functioning.

Long-term psychological and educational outcomes for survivors of neuroblastoma: A report from the Childhood Cancer Survivor Study. Cancer 2018; 124:3220-3230. [PMID: 29888538 DOI: 10.1002/cncr.31379] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2017] [Revised: 01/18/2018] [Accepted: 02/22/2018] [Indexed: 12/18/2022]
Abstract
BACKGROUND Neuroblastoma survivors may be at elevated risk for psychological impairments because of their young age at diagnosis and neurotoxic treatment, but this is not well described. METHODS A total of 859 ≥5-year survivors of neuroblastoma younger than 18 years (diagnosed in 1970-1999), who had a median age at diagnosis of 0.8 years (range: 0.0-7.3 years) and a median follow-up of 13.3 years (range: 8.0-17.9 years), were compared with 872 siblings of childhood cancer survivors who were younger than 18 years with the parent-reported Behavior Problem Index (BPI) for psychological functioning. Age- and sex-adjusted multivariate log-binomial models were used to identify factors associated with impairment in BPI domains (scores worse than the sibling 10th percentile). The impact of psychological impairment on educational outcomes was examined among survivors. RESULTS Compared with siblings, neuroblastoma survivors had an increased prevalence of impairment in the domains of anxiety/depression (19% vs 14%; P = .003), headstrong behavior (19% vs 13%; P < .001), attention deficits (21% vs 13%; P < .001), peer conflict/social withdrawal (26% vs 17%; P < .001), and antisocial behavior (16% vs 12%; P = .01). Common treatment exposures (vincristine, cisplatin, and retinoic acid) were not associated with impairment. Having 2 or more chronic health conditions predicted impairment in 4 domains (P < .001). Specifically, pulmonary disease predicted impairment in all 5 domains (P ≤ .004). Endocrine disease (P ≤ .004) and peripheral neuropathy (P ≤ .02) each predicted impairment in 3 domains. Psychological impairment was associated with special education service usage and educational attainment less than college. CONCLUSIONS Neuroblastoma survivors are at elevated risk for psychological impairment, which is associated with special education service usage and lower adult educational attainment. Those with chronic health conditions may represent a high-risk group for targeted screening and intervention. Cancer 2018. © 2018 American Cancer Society.

Abstract
Recent research has demonstrated that survivors of childhood cancer are at risk for a myriad of late effects that affect physical and mental quality of life. We discuss the patterns and prevalence of neurocognitive problems commonly experienced by survivors of CNS tumors and acute lymphoblastic leukemia, the two most commonly researched cancer diagnoses. Research documenting the direct effects of tumor location and treatment type and intensity is presented, and patient characteristics that moderate outcomes (eg, age at diagnosis and sex) are discussed. Potential biologic mechanisms of neurotoxic treatment exposures, such as cranial irradiation and intrathecal and high-dose antimetabolite chemotherapy, are reviewed. Genetic, brain imaging, and neurochemical biomarkers of neurocognitive impairment are discussed. Long-term survivors of childhood cancer are also at risk for physical morbidity (eg, cardiac, pulmonary, endocrine) and problems with health behaviors (eg, sleep); research is reviewed that demonstrates these health problems contribute to neurocognitive impairment in survivors with or without exposure to neurotoxic therapies. We conclude this review with a discussion of literature supporting specific interventions that may be beneficial in the treatment of survivors who already experience neurocognitive impairment, as well as in the prevention of impairment manifestation.

Perceptions of risk of infertility among male survivors of childhood cancer: A report from the Childhood Cancer Survivor Study. Cancer 2018; 124:2447-2455. [PMID: 29663341 DOI: 10.1002/cncr.31343] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2017] [Revised: 01/31/2018] [Accepted: 02/22/2018] [Indexed: 12/15/2022]
Abstract
BACKGROUND The objective of the current study was to characterize and identify factors associated with perceptions of risk of infertility among adult male survivors of childhood cancer. METHODS A total of 1233 adult male survivors from the Childhood Cancer Survivor Study who were without a history of disease recurrence or subsequent malignancy reported their perceptions of their risk of infertility compared with men never diagnosed with cancer. Survivors were a median age of 37.8 years (range, 22.0-58.7 years) and were 28.4 years from their diagnosis (range, 21.4-39.2 years). Multivariable logistic regression evaluated factors associated with perceptions of risk. RESULTS Overall, 35.9% of the survivors (443 of 1233 survivors) reported perceptions of their risk of infertility that were discordant with their actual risk based on previous cancer treatment exposures. Discordant perceptions were equally common among men exposed to gonadotoxic therapies (36.3%; 311 of 857 men) and those with no history of gonadotoxic exposure (35.1%; 132 of 376 men). Survivors who fathered children (odds ratio [OR], 4.14; 95% confidence interval [95% CI], 2.74-6.24), had no survivor-focused health care (OR, 3.07; 95% CI, 1.57-5.99), were nonwhite (OR, 2.28; 95% CI, 1.10-4.75), and were of lower income were more likely to report no increased risk of infertility after gonadotoxic treatment. Perceptions of increased risk of infertility among men with no history of gonadotoxic treatment were predicted by never having fathered a child (OR, 1.88; 95% CI, 1.17-3.03), recent participation in survivor-focused health care (OR, 2.11; 95% CI, 1.01-4.42), and higher educational achievement. CONCLUSIONS Many male survivors of childhood cancer are unaware of how their cancer treatments could impact their reproductive health, underscoring the need for all patients to receive education regarding their risk of infertility throughout the continuum of cancer care.
