Survivors of childhood cancer may experience accelerated biological aging, resulting in premature frailty and death. We used seven measures of biological age in the St. Jude Lifetime (SJLIFE) Cohort to compare biological age acceleration between the SJLIFE Cohort and the third United States National Health and Nutrition Examination Survey controls, explore trajectories of biological age according to cancer treatment and type, and test associations of biological age acceleration with frailty and death (mean follow-up of 26.5 years) among survivors. Survivors of cancer aged 5% faster per year and measured, on average, 0.6-6.44 years biologically older compared to controls and 5-16 years biologically older compared to age-matched individuals at the population level. Survivors treated with hematopoietic cell transplant and vinca alkaloid chemotherapy evidenced the fastest trajectories of biological aging. Biologically, older and faster-aging survivors consistently and robustly had a higher risk of frailty and died earlier than those with slower biological aging, suggesting a potential opportunity to intervene on excess aging., (© 2024.

Background: Childhood cancer survivors have increased risk of dyslipidemia and atherosclerotic cardiovascular disease (CVD). The aim of this study was to evaluate the prevalence and associated cardiovascular risks of specific lipid abnormalities among childhood cancer survivors., Methods: Comprehensive lipid panel measurements were obtained from 4115 5-year survivors, with 3406 (mean age at evaluation = 35.2 years, SD = 10.4 years) not having previous dyslipidemia diagnosis, as well as 624 age, sex, and race and ethnicity matched community controls., Results: Previously undiagnosed dyslipidemia with abnormal low-density lipoprotein (LDL) cholesterol (>160 mg/dL), non-high density lipoprotein (HDL) cholesterol (>190 mg/dL), HDL cholesterol (<40 mg/dL for men, <50 mg/dL for women), and triglycerides (>150 mg/dL) were identified in 4%, 6%, 30%, and 17%, respectively. Survivors without previous dyslipidemia diagnosis had higher LDL cholesterol and non-HDL cholesterol and lower HDL cholesterol than community controls. Cranial radiotherapy (relative risk [RR] = 2.2, 95% confidence interval [CI] = 1.6 to 3.0 for non-HDL cholesterol) and total body irradiation for hematopoietic cell transplantation (RR = 6.7, 95% CI = 3.5 to 13.0 for non-HDL cholesterol; RR = 9.9, 95% CI = 6.0 to 16.3 for triglycerides) were associated with greater risk of dyslipidemia. Diagnoses of low HDL cholesterol (hazard ratio [HR] = 2.9, 95% CI = 1.8 to 4.7) and elevated triglycerides (HR = 3.1, 95% CI = 1.9 to 5.1) were associated with increased risk for myocardial infarction, and diagnoses of high LDL cholesterol (HR = 2.2, 95% CI = 1.3 to 3.7), high non-HDL cholesterol (HR = 2.2, 95% CI = 1.3 to 3.7), low HDL cholesterol (HR = 3.9, 95% CI = 2.8 to 5.4), and elevated triglycerides (HR = 3.8, 95% CI = 2.7 to 5.5) were associated with increased risk for cardiomyopathy., Conclusions: Previously undiagnosed dyslipidemia among childhood cancer survivors was associated with increased risk for myocardial infarction and cardiomyopathy. Comprehensive dyslipidemia evaluation and treatment are needed to reduce cardiovascular morbidity in this population., (© The Author(s) 2023. Published by Oxford University Press.

Purpose: The impact of changes in therapy for childhood acute lymphoblastic leukemia (ALL) and non-Hodgkin lymphoma (NHL) on the prevalence of physical performance limitations and participation restrictions among survivors is unknown. We aimed to describe the prevalence of reduced function among ALL and NHL survivors by treatment era., Methods: Participants included survivors of childhood ALL and NHL, and a cohort of their siblings, participating in the Childhood Cancer Survivor Study (CCSS). Physical function was measured using questionnaire. The prevalence of reduced function was compared to siblings using generalized estimating equations, overall and stratified by treatment decade. Associations between organ system-specific chronic conditions (CTCAE v4.03) and function were also evaluated., Results: Among 6511 survivors (mean age 25.9 years (standard deviation 6.5)) and 4127 siblings, risk of performance limitations (15.2% vs. 12.5%, prevalence ratio [PR] = 1.5, 95%CI = 1.3-1.6), restrictions in personal care (2.0% vs. 0.6%, PR = 3.1, 95% CI = 2.0-4.8), routine activities (5.5% vs. 1.6%, PR = 3.6, 95% CI = 2.7-4.8), and work/school attendance (8.8% vs. 2.1%, PR = 4.5, 95% CI = 3.6-5.7) was increased in survivors vs. siblings. The prevalence of survivors reporting reduced function did not decrease between the 1970s and 1990s. The presence of neurological and cardiovascular conditions was associated with reduced function regardless of treatment decade., Conclusions: Despite changes in therapy, the prevalence of poor physical function remained constant between the 1970s and 1990s. The CCSS clinical trial registration number is NCT01120353 (registered May 6, 2010)., Implications for Cancer Survivors: Our findings support screening for reduced physical function so that early interventions to improve physical performance and mitigate chronic disease can be initiated., (© 2023.

Objective: This study used childhood cancer survivors as a novel model to study whether children who experience central nervous system (CNS) injury are at higher risk for neurocognitive impairment associated with subsequent late onset chronic health conditions (CHCs)., Methods: Adult survivors of childhood cancer (n = 2,859, ≥10 years from diagnosis, ≥18 years old) completed a comprehensive neurocognitive battery and clinical examination. Neurocognitive impairment was defined as age-adjusted z score < 10th percentile. Participants impaired on ≥3 tests had global impairment. CHCs were graded using the Common Terminology Criteria for Adverse Events v4.3 (grade 1, mild; 2, moderate; 3, severe/disabling; 4, life-threatening) and were combined into a severity/burden score by frequency and grade (none/low, medium, high, and very high). A total of 1,598 survivors received CNS-directed therapy including cranial radiation, intrathecal methotrexate, or neurosurgery. Logistic regression estimated the odds of neurocognitive impairment associated with severity/burden score and grade 2 to 4 conditions, stratified by CNS treatment., Results: CNS-treated survivors performed worse than non-CNS-treated survivors on all neurocognitive tests and were more likely to have global neurocognitive impairment (46.9% vs 35.3%, p < 0.001). After adjusting for demographic and treatment factors, there was a dose-response association between severity/burden score and global neurocognitive impairment, but only among CNS-treated survivors (high odds ratio [OR] = 2.24, 95% confidence interval [CI] = 1.42-3.53; very high OR = 4.07, 95% CI = 2.30-7.17). Cardiovascular and pulmonary conditions were associated with processing speed, executive function, and memory impairments in CNS-treated but not non-CNS-treated survivors who were impacted by neurologic conditions., Interpretation: Reduced cognitive/brain reserve associated with CNS-directed therapy during childhood may make survivors vulnerable to adverse cognitive effects of cardiopulmonary conditions during adulthood.

Background: The objective of this study was to characterize chronic disease, health-related quality of life (HRQOL), emotional distress, and social attainment among long-term survivors of neuroblastoma., Methods: Chronic health conditions among 136 ≥10-year neuroblastoma survivors (median age, 31.9 years; range, 20.2-54.6 years) and 272 community controls (median age, 34.7 years; range, 18.3-59.6 years) were graded with a modified version of the Common Terminology Criteria for Adverse Events (version 4.03). HRQOL and emotional distress were assessed with the Medical Outcomes Study 36-Item Short Form Health Survey and the Brief Symptom Inventory-18. Log-binomial regression and logistic regression were used to compare the prevalence of chronic conditions and the frequency of reduced HRQOL, distress, and social attainment between survivors and controls. The cumulative burden approach was used to estimate multimorbidity., Results: By the age of 35 years, survivors had experienced, on average, 8.5 grade 1 to 5 conditions (95% confidence interval [CI], 7.6-9.3), which was higher than the average for controls (3.3; 95% CI, 2.9-3.7). Compared with controls, survivors had a higher prevalence of any pulmonary (P = .003), auditory (P < .001), gastrointestinal (P < .001), neurological (P = .003), or renal condition (P < .001); were more likely to report poor physical HRQOL (P = .01) and symptoms of anxiety (P = .01) and somatization (P = .01); and were less likely to live independently (P = .01) or marry (P = .01). In analyses limited to survivors, those with 1 or more grade 3 to 5 conditions were more likely to report reduced general health (odds ratio [OR], 6.6; 95% CI, 1.6-26.9), greater bodily pain (OR, 4.2; 95% CI, 1.0-17.0), and unemployment (OR, 3.2; 95% CI, 1.2-8.5)., Conclusions: Because of the high burden of chronic diseases and the associations of these morbidities with reduced HRQOL and social attainment, screening and interventions that provide opportunities to optimize health are important among neuroblastoma survivors., (© 2020 American Cancer Society.)

Purpose: This study compared the measurement properties for multiple modes of survey administration, including postal mail, telephone interview, and Web-based completion of patient-reported outcomes (PROs) among survivors of childhood cancer., Methods: The population included 6,974 adult survivors of childhood cancer in the Childhood Cancer Survivor Study who completed the Brief Symptom Inventory-18 (BSI-18), which measured anxiety, depression, and somatization symptoms. Scale reliability, construct validity, and known-groups validity related to health status were tested for each mode of completion. The multiple indicators and multiple causes technique was used to identify differential item functioning (DIF) for the BSI-18 items that responded through a specific survey mode. The impact of the administration mode was tested by comparing differences in BSI-18 scores between the modes accounting for DIF effects., Results: Of the respondents, 58%, 27%, and 15% completed postal mail, Web-based, and telephone surveys, respectively. Survivors who were male; had lower education, lower household income, or poorer health status; or were treated with cranial radiotherapy were more likely to complete a telephone-based survey compared with either a postal mail or Web-based survey (all P < .05). Scale reliability and validity were equivalent across the 3 survey options. One, 2, and 5 items from the anxiety, depression, and somatization domains, respectively, were identified as having significant DIF among survivors who responded by telephone ( P < .05). However, estimated BSI-18 domain scores, especially depression and anxiety, between modes did not differ after accounting for DIF effects., Conclusion: Certain survivor characteristics were associated with choosing a specific mode for PRO survey completion. However, measurement properties among these modes were equivalent, and the impact of using a specific mode on scores was minimal.

Purpose: To examine prevalence and predictors of neurocognitive outcomes, social attainment, emotional distress, and health-related quality of life (HRQOL) in long-term survivors of pediatric Wilms tumor (WT)., Methods: One hundred fifty-eight WT survivors (59% female; mean [SD] age 33 [9.1] years; time since diagnosis 29 [9.1] years) and 354 community controls (55.6% female; 35 [10.2] years) completed comprehensive neuropsychological testing and physical examination, including echocardiography/electrocardiography, pulmonary function tests, and endocrine evaluation. Self-report of emotional distress, HRQOL, and social attainment were collected. Impairment was defined in relation to both controls and normative data. Generalized linear models were developed to examine impact of treatment and chronic health conditions on outcomes., Results: WT survivors performed poorer than norms and controls in 6 of 16 cognitive variables and 1 of 8 HRQOL variables, with scores ranging from - 0.64 (mathematics) to - 0.21 (verbal fluency) standard deviations below expectations. Compared to controls, WT survivors were less likely to graduate college (odds ratio 2.23, 95% confidence interval 1.46-3.41) and had more moderate to severe neurologic conditions (18.4% vs 8.2%, p < 0.001), which were associated with poor memory (β = - 0.90, p < 0.001), attention (β = - 1.02, p < 0.001), and HRQOL general health (β = - 0.80, p = 0.0015). Treatment variables and cardiopulmonary morbidity (higher in survivors) were not associated with outcomes., Conclusions: Survivors of WT demonstrate impairment in neurocognitive function and have lower social attainment during adulthood, with poorer neurocognitive function associated with neurologic morbidity., Implications for Cancer Survivors: Survivors of WT should be offered neurocognitive evaluations and rehabilitation. Neurologic conditions should be routinely assessed, and appropriate support offered to reduce risk for functional limitations.

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., Funding: US National Cancer Institute and the American Lebanese Syrian Associated Charities., (Copyright © 2019 Elsevier Ltd.
