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

Background: To the authors' knowledge, few studies to date have examined long-term neurocognitive outcomes in survivors of childhood soft-tissue sarcoma. Methods: A total of 150 survivors (41% of whom were female with a mean current age of 33 years [SD, 8.9 years] and a time since diagnosis of 24 years [SD, 8.7 years]) and 349 community controls (56% of whom were female with a mean current age of 35 years [SD, 10.2 years]) completed comprehensive neuropsychological testing, echocardiography, electrocardiography, pulmonary function tests, endocrine evaluation, and physical examination. Patient-reported outcomes of health-related quality of life (HRQOL) and social attainment were collected. Survivors were compared with norms and controls on neurocognitive outcomes using general linear models, and on HRQOL and social attainment using modified Poisson models. The impacts of treatment and chronic health conditions on outcomes were examined using multivariable general linear models (effect size was expressed as unstandardized β estimates that reflected the unit of change from a mean of 0 and an SD of 1) and modified Poisson models (effect size expressed as relative risks). Results: Compared with controls and population norms, survivors demonstrated lower performance on measures of verbal reasoning (mean z score, −0.45 [SD, 1.15]; P

PURPOSE Exercise intolerance, associated with heart failure and death in general populations, is not well studied in survivors of childhood cancer. We examined prevalence of exercise intolerance in survivors exposed or not to cardiotoxic therapy, and associations among organ system function, exercise intolerance, and mortality. METHODS Participants consisted of 1,041 people who had survived cancer ≥ 10 years (and had or did not have exposure to anthracyclines and/or chest-directed radiation) and 285 control subjects. Exercise intolerance was defined as peak oxygen uptake < 85% predicted from maximal cardiopulmonary exercise testing; organ functions were ascertained with imaging or clinical testing. Multivariable regression of the data was performed to compare exercise capacity between survivors exposed or unexposed to cardiotoxic therapy and control subjects, and to evaluate associations between treatment and organ function, and organ function and exercise intolerance. Propensity score methods in time-to-event analyses evaluated associations between exercise intolerance and mortality. RESULTS Survivors (mean age ± standard deviation [SD], 35.6 ± 8.8 years) had lower mean (± SD) peak oxygen uptake (exposed: 25.74 ± 8.36 mL/kg/min; unexposed: 26.82 ± 8.36 mL/kg/min) than did control subjects (32.69 ± 7.75 mL/kg/min; P for all < .001). Exercise intolerance was present in 63.8% (95% CI, 62.0% to 65.8%) of exposed survivors, 55.7% (95% CI, 53.2% to 58.2%) of unexposed survivors, and 26.3% (95% CI, 24.0% to 28.3%) of control subjects, and was associated with mortality (hazard ratio, 3.9; 95% CI, 1.09 to 14.14). Global longitudinal strain (odds ratio [OR], 1.71; 95% CI, 1.11 to 2.63), chronotropic incompetence (OR, 3.58; 95% CI, 1.75 to 7.31); forced expiratory volume in 1 second < 80% (OR, 2.59; 95% CI, 1.65 to 4.09), and 1 SD decrease in quadriceps strength (OR, 1.49; 95% CI, 1.23 to 1.82) were associated with exercise intolerance. Ejection fraction < 53% was not associated with exercise intolerance. CONCLUSION Exercise intolerance is prevalent among childhood cancer survivors and associated with all-cause mortality. Treatment-related cardiac (detected by global longitudinal strain), autonomic, pulmonary, and muscular impairments increased risk. Survivors with impairments may require referral to trained specialists to learn to accommodate specific deficits when engaging in exercise.

Background Long-term survivors of pediatric acute lymphoblastic leukemia are at elevated risk for neurocognitive deficits and corresponding brain dysfunction. This study examined sex-based differences in functional neuroimaging outcomes in acute lymphoblastic leukemia survivors treated with chemotherapy alone. Methods Functional magnetic resonance imaging (fMRI) and neurocognitive testing were obtained in 123 survivors (46% male; median [min-max] age = 14.2 years [8.3-26.5 years]; time since diagnosis = 7.7 years [5.1-12.5 years]) treated on the St. Jude Total XV treatment protocol. Participants performed the n-back working memory task in a 3 T scanner. Functional neuroimaging data were processed (realigned, slice time corrected, normalized, smoothed) and analyzed using statistical parametric mapping with contrasts for 1-back and 2-back conditions, which reflect varying degrees of working memory and task load. Group-level fMRI contrasts were stratified by sex and adjusted for age and methotrexate exposure. Statistical tests were 2-sided (P Results Relative to males, female survivors exhibited less activation (ie, reduced blood oxygen dependent–level signals) in the right parietal operculum, supramarginal gyrus and inferior occipital gyrus, and bilateral superior frontal medial gyrus during increased working memory load (family-wise error–corrected P = .004 to .008, adjusting for age and methotrexate dose). Female survivors were slower to correctly respond to the 2-back condition than males (P Conclusions These results suggest the working memory network is more impaired in female survivors than male survivors, which may contribute to ongoing functional deficits.

Background Early initiation of breast cancer screening is recommended for high-risk women, including survivors of childhood cancer treated with chest radiation. Recent studies suggest that female survivors of childhood leukemia or sarcoma treated without chest radiation are also at elevated early onset breast cancer risk. However, the potential clinical benefits and cost-effectiveness of early breast cancer screening among these women are uncertain. Methods Using data from the Childhood Cancer Survivor Study, we adapted 2 Cancer Intervention and Surveillance Modeling Network simulation models to reflect the elevated risks of breast cancer and competing mortality among leukemia and sarcoma survivors. Costs and utility weights were based on published studies and databases. Outcomes included breast cancer deaths averted, false-positive screening results, benign biopsies, and incremental cost-effectiveness ratios. Results In the absence of screening, the lifetime risk of dying from breast cancer among survivors was 6.8% to 7.0% across models. Early initiation of annual mammography with breast magnetic resonance imaging screening between ages 25 and 40 years would avert 52.6% to 64.3% of breast cancer deaths. When costs and quality-of-life impacts were considered, screening starting at age 40 years was the only strategy with an incremental cost-effectiveness ratio below the $100 000 per quality-adjusted life-year (QALY) gained cost-effectiveness threshold ($27 680 to $44 380 per QALY gained across models). Conclusions Among survivors of childhood leukemia or sarcoma, early initiation of breast cancer screening at age 40 years may reduce breast cancer deaths by half and is cost-effective. These findings could help inform screening guidelines for survivors treated without chest radiation.

Background and Objectives:There is insufficient evidence to support stroke prevention guidelines for childhood cancer survivors (CCS) treated with cranial irradiation for central nervous system (CNS) tumors or other childhood cancers involving the CNS. We used a systematic consensus-building methodology to develop expert recommendations and define areas of controversy in managing asymptomatic CCS at risk for stroke.Methods:A Delphi process was used to query a multi-specialty panel of 45 physicians from US/Canada, with expertise in CCS, about their stroke screening and management practices (imaging, referrals, laboratory testing, and medications). Three iterative rounds of anonymous, scenario-based questionnaires, building on panelists’ aggregate responses, were used to reach consensus (≥ 90% agreement), agreement (89-70% agree), or to understand rationale for disagreement (< 70% agree).Results:All 45 physicians participated in first two rounds and 44 in the third. Panelists reached consensus on indications for referral to neurology and laboratory screening for modifiable cerebral vascular disease (CVD) risk factors in most scenarios. Panelists agree that aspirin therapy is not recommended in the scenario of normal neuroimaging (86% agree). Decisions about aspirin therapy in scenarios with abnormal neuroimaging were deferred to specialists; almost all agree with not using aspirin for cavernomas with no evidence for prior hemorrhage (93%) and using aspirin for both large vessel CVD (93%) and small vessel CVD with evidence of prior stroke (86%). Clinical decisions that remain controversial (less than 70% agreement) include neuroimaging to screen asymptomatic CCS for CVD, referral to neurology for cavernomas, aspirin use in the setting of cavernomas with prior hemorrhage or with evidence for small vessel CVD and no prior stroke, and indications for statins. Overall, pediatric neurologists/neuro-oncologists and radiation oncologists were more likely to advocate for screening and interventions.Discussion:Despite lack of evidence to guide management of CCS at risk for stroke, expert recommendations and rationale developed by consensus-methodology are helpful to support clinical decision making.

PurposeThe International Consortium for Pooled Studies on Subsequent Malignancies after Childhood and Adolescent Cancer was established in 2018 to address gaps in knowledge of risk and risk factors for breast cancer subsequent to childhood/adolescent cancer by pooling individual patient data from seven cohorts. Initially, the pooled cohort will focus on three clinically relevant questions regarding treatment-related subsequent breast cancer risk in female survivors, which are the risk related to low-dose radiotherapy exposure to the chest, specific chemotherapy agents and attained age.ParticipantsThe consortium database includes pooled data on 21 892 female survivors from seven cohorts in North America and Europe with a primary cancer diagnosis at Findings to dateThis is a newly established pooled study. The cohort profile summarised the data collected from each included cohort, including childhood cancer diagnosis information and treatment details (ie, radiotherapy fields and cumulative doses, and chemotherapy agents and cumulative doses for each agent). Included cohorts’ follow-up started 1951–1981 and ended 2013–2021, respectively, for a median follow-up duration of 24.3 (IQR 18.0–32.8) years since primary cancer diagnosis. The median age at primary cancer diagnosis was 5.4 (IQR 2.5–11.9) years. And the median attained age at last follow-up was 32.2 (IQR 24.0–40.4) years. In all, 4240 (19.4%) survivors were treated with radiotherapy to the chest and 9308 (42.5%) with anthracyclines. At the end of the follow-up, 835 females developed a first subsequent breast cancer, including 635 invasive breast cancer only, 184 carcinomas in situ only (172 ductal carcinomas in situ and 12 lobular carcinomas in situ), and 16 with both an invasive and in situ diagnosis at the same moment. The cumulative incidences of subsequent breast cancer (both invasive and in situ) 25 and 35 years after primary cancer diagnosis were 2.2% and 6.2%, respectively.Future plansThe consortium is intended to serve as a model and robust source of childhood/adolescent cancer survivor data for elucidating other knowledge gaps on subsequent breast cancer risk, and risk of other subsequent malignancies (including data on males) in the future.

Item does not contain fulltext Survivors of childhood cancer are at risk of anthracycline-induced cardiotoxicity, which might be prevented by dexrazoxane. However, concerns exist about the safety of dexrazoxane, and little guidance is available on its use in children. To facilitate global consensus, a working group within the International Late Effects of Childhood Cancer Guideline Harmonization Group reviewed the existing literature and used evidence-based methodology to develop a guideline for dexrazoxane administration in children with cancer who are expected to receive anthracyclines. Recommendations were made in consideration of evidence supporting the balance of potential benefits and harms, and clinical judgement by the expert panel. Given the dose-dependent risk of anthracycline-induced cardiotoxicity, we concluded that the benefits of dexrazoxane probably outweigh the risk of subsequent neoplasms when the cumulative doxorubicin or equivalent dose is at least 250 mg/m(2) (moderate recommendation). No recommendation could be formulated for cumulative doxorubicin or equivalent doses of lower than 250 mg/m(2), due to insufficient evidence to determine whether the risk of cardiotoxicity outweighs the possible risk of subsequent neoplasms. Further research is encouraged to determine the long-term efficacy and safety of dexrazoxane in children with cancer.

ImportanceAssociations between modifiable chronic health conditions (CHCs), social determinants of health, and late mortality (defined as death occurring ≥5 years after diagnosis) in childhood cancer survivors are unknown.ObjectiveTo explore associations between modifiable CHCs and late mortality within the context of social determinants of health.Design, Setting, and ParticipantsThis longitudinal cohort study used data from 9440 individuals who were eligible to participate in the St Jude Lifetime Cohort (SJLIFE), a retrospective cohort study with prospective clinical follow-up that was initiated in 2007 to characterize outcomes among childhood cancer survivors. Eligible individuals had survived 5 or more years after childhood cancer diagnosis, were diagnosed between 1962 and 2012, and received treatment at St Jude Children’s Research Hospital were included in mortality estimates. A total of 3407 adult SJLIFE participants (aged ≥18 years) who completed an on-campus assessment were included in risk factor analyses. Vital status, date of death, and cause of death were obtained by linkage with the National Death Index (coverage from inception to December 31, 2016). Deaths occurring before inception of the National Death Index were obtained from the St Jude Children’s Research Hospital Cancer Registry. Data were analyzed from June to December 2022.ExposuresData on treatment exposures and causes of death were abstracted for individuals who were eligible to participate in the SJLIFE study. Information on modifiable CHCs (dyslipidemia, hypertension, diabetes, underweight or obesity, bone mineral deficiency, hypogonadism, hypothyroidism, and adrenal insufficiency, all graded by the modified Common Terminology Criteria for Adverse Events), healthy lifestyle index (smoking status, alcohol consumption, body mass index [calculated as weight in kilograms divided by height in meters squared], and physical activity), area deprivation index (ADI; which measures neighborhood-level socioeconomic disadvantage), and frailty (low lean muscle mass, exhaustion, low energy expenditure, slowness, and weakness) was obtained for participants.Main Outcomes and MeasuresNational Death Index causes of death were used to estimate late mortality using standardized mortality ratios (SMRs) and 95% CIs, which were calculated based on US mortality rates. For the risk factor analyses (among participants who completed on-campus assessment), multivariable piecewise exponential regression analysis was used to estimate rate ratios (RRs) and 95% CIs for all-cause and cause-specific late mortality.ResultsAmong 9440 childhood cancer survivors who were eligible to participate in the SJLIFE study, the median (range) age at assessment was 27.5 (5.3-71.9) years, and the median (range) duration of follow-up was 18.8 (5.0-58.0) years; 55.2% were male and 75.3% were non-Hispanic White. Survivors experienced increases in all-cause mortality (SMR, 7.6; 95% CI, 7.2-8.1) and health-related late mortality (SMR, 7.6; 95% CI, 7.0-8.2). Among 3407 adult SJLIFE participants who completed an on-campus assessment, the median (range) age at assessment was 35.4 (17.9-69.8) years, and the median (range) duration of follow-up was 27.3 (7.3-54.7) years; 52.5% were male and 81.7% were non-Hispanic White. Models adjusted for attained age, sex, race and ethnicity, age at diagnosis, treatment exposures, household income, employment status, and insurance status revealed that having 1 modifiable CHC of grade 2 or higher (RR, 2.2; 95% CI, 1.2-4.0; P = .01), 2 modifiable CHCs of grade 2 or higher (RR, 2.6; 95% CI, 1.4-4.9; P = .003), or 3 modifiable CHCs of grade 2 or higher (RR, 3.6; 95% CI, 1.8-7.1, P P = .02), an ADI in the 81st to 100th percentile (RR, 8.7; 95% CI, 2.0-37.6; P = .004), or an unassigned ADI (RR, 15.7; 95% CI, 3.5-70.3; P P = .004) were associated with significant increases in the risk of late all-cause death. Similar associations were observed for the risk of late health-related death (1 modifiable CHC of grade ≥2: RR, 2.2 [95% CI, 1.1-4.4; P = .02]; 2 modifiable CHCs of grade ≥2: RR, 2.5 [95% CI, 1.2-5.2; P = .01]; 3 modifiable CHCs of grade ≥2: RR, 4.0 [95% CI, 1.9-8.4; P P = .03]; ADI in 81st-100th percentile: RR, 16.2 [95% CI, 2.1-123.7; P = .007], unassigned ADI: RR, 27.3 [95% CI, 3.5-213.6; P = .002]; and frailty: RR, 2.3 [95% CI, 1.2-4.1; P = .009]).Conclusions and RelevanceIn this cohort study of childhood cancer survivors, living in a Census block with a high ADI and having modifiable CHCs were independently associated with an increased risk of late death among survivors of childhood cancer. Future investigations seeking to mitigate these factors will be important to improving health outcomes and developing risk-stratification strategies to optimize care delivery to childhood cancer survivors.

Patient-reported outcome measures (PROMs) are subjective assessments of health status or health-related quality of life. In childhood cancer survivors, PROMs can be used to evaluate the adverse effects of cancer treatment and guide cancer survivorship care. However, there are barriers to integrating PROMs into clinical practice, such as constraints in clinical validity, meaningful interpretation, and technology-enabled administration of the measures. This article discusses these barriers and proposes 10 important considerations for appropriate PROM integration into clinical care for choosing the right measure (considering the purpose of using a PROM, health profile vs. health preference approaches, measurement properties), ensuring survivors complete the PROMs (data collection method, data collection frequency, survivor capacity, self- vs. proxy reports), interpreting the results (scoring methods, clinical meaning and interpretability), and selecting a strategy for clinical response (integration into the clinical workflow). An example framework for integrating novel patient-reported outcome (PRO) data collection into the clinical workflow for childhood cancer survivorship care is also discussed. As we continuously improve the clinical validity of PROMs and address implementation barriers, routine PRO assessment and monitoring in pediatric cancer survivorship offer opportunities to facilitate clinical decision making and improve the quality of survivorship care.

Background: We have previously reported that epigenetic age acceleration (EAA) was associated with prior cancer treatment exposures and certain chronic health conditions (CHCs) among adult survivors of childhood cancer, but the early epigenetic aging pattern among children and adolescent survivors and its implication in CHCs, especially early-onset CHCs, remain to be explored.

Background: Childhood cancer survivors are a growing population at elevated risk for premature aging and age-related chronic health conditions (CHCs) compared to the general population. In the general population, diet affects many hallmarks of aging, including inflammation, metabolic dysfunctions, and molecular and epigenetic changes. We examined associations between dietary patterns and risk of premature aging in adult survivors of childhood cancer. Methods: Adult survivors (18-65 years old, mean [SD] age 31 [8.4] years) of childhood cancer enrolled in SJLIFE between 2007 and 2017 completed a 110-item food frequency questionnaire at enrollment (n=2,904). Sociodemographic, cancer, cancer treatments, and health history were abstracted from medical records; CHCs were clinically validated. Factor analysis was performed to identify dietary patterns specific to the study population. Premature aging was assessed using the Deficit Accumulation Index (DAI) based on 45 age-related CHCs and categorized into low (0.35) aging risk groups. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using multinomial logistic regressions adjusting for potential confounders, such as sociodemographics, health behaviors, and cancer treatments. Individuals’ factor scores of each pattern were grouped into quintiles, and a median score of each quintile was entered as a continuous term in regression models. Results: 20% of survivors were at medium- and 8% were at high-risk for premature aging. Survivors at high-risk for premature aging were more likely to be female, smokers, have low socioeconomic status, and have received radiation therapy to head and neck, chest, spine, or abdomen compared to those at low premature aging risk. Three dietary patterns were identified: 1) plant-based, 2) fast-food, and 3) Western contemporary. A plant-based diet was characterized by greater intakes of vegetables, fruits, whole grains, and fish. A higher plant-based diet pattern score was associated with a lower risk of premature aging (OR=0.76, 95% CI: 0.62-0.94 for the high-risk group; OR=0.91, 95% CI: 0.79-1.04 for the medium-risk group). A fast-food diet was characterized by greater intakes of sweets, processed meat, refined grains, potato, high-fat dairy, and soda. A fast-food diet was related to a non-significant increased risk of premature aging (OR=1.20, 95% CI: 0.91-1.57 for the high-risk group; OR=1.18, 95% CI: 0.98-1.43 for the medium-risk group). A Western contemporary diet characterized by greater intakes of meat, pasta/rice, pizza, Mexican food, and fruit juice was associated with an increased risk of premature aging (OR=1.36, 95% CI: 1.05-1.78 for the high-risk group; OR=1.04, 95% CI: 0.87-1.26 for the medium-risk group). Conclusion: Our findings suggest that diet plays a role in aging, and a diet rich in plant-based foods may mitigate the risk of premature aging in childhood cancer survivors.

Background: In the general population, sugar intake is associated with a wide range of adverse health conditions related to premature aging, including obesity, diabetes, and cardiovascular disease. Childhood cancer survivors are at increased risk of premature aging and mortality compared to their healthy peers and may be especially vulnerable to adverse consequences of excess sugar intake. Objective: To examine the association between sugar and sugar-sweetened beverage intake and premature aging in childhood cancer survivors. Method: A total of 3,322 adult survivors of childhood cancer (age range 18-65 years; mean age: 31 years) in SJLIFE self-reported their typical diet using the 110-item Block Food Frequency Questionnaire. Added sugars included all sugars added to foods during preparation or processing. Total sugar-sweetened beverages are the sum of regular and diet soda and fruit-flavored drinks. Survivors’ sociodemographics, cancer histories, and health conditions were abstracted from medical records. Premature aging was assessed using the Deficit Accumulation Index (DAI) that was a ratio of the number of age-related chronic health conditions each survivor had out of 45 conditions total. The DAI was categorized into low (0.35) aging risk groups. Multinomial logistic regressions (reference: low aging risk group) adjusting for confounders, including sociodemographics, lifestyle factors, cancer treatments, and overall diet quality, were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Results: Survivors’ average total sugar intake was 120 g/day and added sugar intake was 71 g/day. 41% of survivors consumed sugar-sweetened beverages ≥1 time/day, and 26% consumed soda daily; 75% of soda consumed was regular (vs. diet). Survivors with higher consumption of sugar and sugar-sweetened beverages were more likely to be non-Hispanic Black and have lower educational attainment and income. Total sugar intake was associated with a significantly increased risk of premature aging (per 25 g/1,000 kcal increment, OR=1.31 [95% CI: 1.00-1.70] in the medium-risk group; OR=1.52 [95% CI: 1.03-2.25] in the high-risk group). Added sugar intake was associated with a 19% (OR=1.19, 95% CI: 1.07-1.31, per 20 g/1,000 kcal increment) and an 18% (OR=1.18, 95% CI: 1.02-1.37) increased risk of premature aging in the medium- and high-risk group, respectively. Consuming ≥2 servings/day (vs. ≤ 1/week) of total sugar-sweetened beverage was also related to an increased risk of premature aging (OR=1.54 [95% CI: 0.83-2.83] in the medium-risk group; OR=6.71 [95% CI: 2.95-15.2] in the high-risk group). Regular soda, but not diet soda, consumption was associated with premature aging risk. Conclusion: Higher consumption of sugar and sugar-sweetened beverages was associated with an increased risk of premature aging in childhood cancer survivors. Intervention efforts to reduce sugar intake among this vulnerable population are needed. Citation Format: Tuo Lan, Mei Wang, AnnaLynn M. Williams, Matthew J. Ehrhardt, Emily R. Finch, Jennifer Q.

Cardiovascular disease is up to 10 times more likely among childhood cancer survivors compared to siblings. Low cardiorespiratory fitness is a modifiable risk-factor for cardiovascular diseases. Yet, cardiorespiratory fitness is not routinely screened in pediatric oncology, and healthy VO2max cut-points are unavailable. We aimed to predict cardiorespiratory fitness by developing a simple algorithm and establish cut-points identifying survivors' cardiovascular fitness health-risk zones. We recruited 262 childhood cancer survivors (8-18 years old, ≥1-year posttreatment). Participants completed gold-standard cardiorespiratory fitness assessment (Cardiopulmonary Exercise Test [CPET; VO2max ]) and 6-minute walk test (6MWT). Associations with VO2max were included in a linear regression algorithm to predict VO2max , which was then cross-validated. We used Bland-Altman's limits of agreement and Receiver Operating Characteristic curves using FITNESSGRAM's "Healthy Fitness Zones" to identify cut-points for adequate cardiorespiratory fitness. A total of 199 participants (aged 13.7 ± 2.7 years, 8.5 ± 3.5 years posttreatment) were included. We found a strong positive correlation between VO2max and 6MWT distance (r = 0.61, r2 = 0.37, p

BACKGROUND Motivational interviewing is an effective strategy to mitigate chronic disease risk through promotion of health behavior changes. However, multiple barriers impede its delivery to and uptake by patients. mHealth-based versions of motivational interviewing interventions, or technology-delivered adaptations of motivational interviewing (TAMIs), might increase reach, but their effectiveness is less well-understood. OBJECTIVE The purpose of this narrative review was to characterize the extent to which TAMIs: (1) affect behavioral outcomes, (2) have included individuals from populations that have been marginalized, and (3) have addressed socio-contextual influences on health. METHODS We identified studies indexed in PubMed that described interventions incorporating motivational interviewing techniques into a mobile or electronic health platform. Data were abstracted from eligible studies, including target population characteristics, study design and eligibility criteria, theoretical/conceptual models utilized, mHealth tool details, and effects on behavioral outcomes. RESULTS Thirty-three studies reported the use of TAMIs. Sample sizes ranged from 10 to 2,069 participants ages 13 to 70 years. Most studies (n=24) directed interventions towards individuals engaging in behaviors that increased the risk of chronic disease. Most studies oversampled (n=18) individuals from marginalized socio-demographic groups, but few were designed specifically with marginalized groups in mind (n=3). TAMIs utilized text messaging (n=7), web-based (n=19), app + text messaging (n=1), and web-based + text messaging (n=3) delivery platforms. Twenty-seven (90%) included randomized controlled trials reporting behavioral and health-related outcomes, 21 of which reported statistically significant improvements in targeted behaviors with the use of TAMIs. TAMIs improved targeted health behaviors in the remaining 3 studies. Nine of 30 (30%) assessed TAMI feasibility, acceptability, and/or satisfaction, all of which rated TAMIs highly in this regard. Among 18 studies comprised of a disproportionately high number of racial or ethnic minorities, 15 (83%) reported increased engagement in health behaviors and/or better health outcomes. CONCLUSIONS TAMIs can improve health promotion and disease management behaviors for people from a variety of socio-demographic backgrounds. Future studies are needed to determine the contribution of TAMIs on individual health outcomes, and to determine best practices for implementing TAMIs into clinical practice.

Adult survivors of childhood cancer have high rates of obesity, which, in combination with the cardiotoxic effects of specific cancer therapies, places them at high risk for cardiovascular morbidity. Here we show the contribution of genetic risk scores (GRSs) to increase prediction of those survivors of childhood cancer who are at risk for severe obesity (body mass index ≥40 kg m

BACKGROUND Data on primary hypothyroidism and its long-term impact on the health, cognition, and quality of life (QOL) of childhood cancer survivors are limited. This study examined the prevalence of and risk factors for primary hypothyroidism and its associations with physical, neurocognitive, and psychosocial outcomes. METHODS This was a retrospective study with a cross-sectional health outcome analysis of an established cohort comprising 2965 survivors of childhood cancer (52.8% male; median current age, 30.9 years, median time since cancer diagnosis, 22.3 years). Multivariable logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs) for associations between primary hypothyroidism and cancer-related risk factors, cardiovascular disease risk factors, frailty, neurocognitive and QOL outcomes, social attainment, and subsequent thyroid carcinoma. Associations between serum free thyroxine and thyrotropin levels at assessment and health outcomes were explored. RESULTS The prevalence of primary hypothyroidism was 14.7% (95% CI, 13.5%-16.0%). It was more likely in females (OR, 1.06; 95% CI, 1.03-1.08), was less likely in non-Whites (OR, 0.96; 95% CI, 0.93-0.99), was associated with thyroid radiotherapy (higher risk at higher doses), and was more common if cancer was diagnosed at an age ≥ 15.0 years versus an age

Background Adult survivors of childhood cancer are at risk of developing sleep and neurocognitive problems, yet few efficacious interventions exist targeting these prevalent late effects. Melatonin has known sleep-promoting effects; however, it has not been well studied among childhood cancer survivors. Method Survivors (n = 580; mean age = 33.5 years; 26 years post-diagnosis) from the St. Jude Lifetime Cohort were randomized (1:1) to a six-month double-blind placebo-controlled trial of 3 mg time-release melatonin within three strata (stratum 1: neurocognitive impairment only; stratum 2: neurocognitive and sleep impairment; stratum 3: sleep impairment only). Neurocognitive performance was assessed at baseline and post-intervention using standardized measures. Sleep was assessed via self-report and actigraphy. Independent sample t tests compared mean change scores from baseline to six months. Post-hoc analyses compared the prevalence of clinically significant treatment responders among melatonin and placebo conditions within and across strata. Results Intent-to-treat analyses revealed no statistically significant differences in neurocognitive performance or sleep from baseline to post-intervention. However, among survivors with neurocognitive impairment only, a larger proportion randomized to melatonin versus placebo demonstrated a treatment response for visuomotor speed (63% vs 41%, P = 0.02) and nonverbal reasoning (46% vs 28%, P = 0.04). Among survivors with sleep impairment only, a larger proportion treated with melatonin demonstrated a treatment response for shifting attention (44% vs 28%, P = 0.05), short-term memory (39% vs 19%, P = 0.01), and actigraphy-assessed sleep duration (47% vs 29%, P = 0.05). Conclusion Melatonin was not associated with improved neurocognitive performance or sleep in our intent-to-treat analyses; however, a subset of survivors demonstrated a clinically significant treatment response.

Background: Female childhood cancer survivors (CCSs) carry a risk of therapy-related gonadal dysfunction. Alkylating agents (AA) are well-established risk factors, yet inter-individual variability in ovarian function is observed. Polymorphisms in CYP450 enzymes may explain this variability in AA-induced ovarian damage. We aimed to evaluate associations between previously identified genetic polymorphisms in CYP450 enzymes and AA-related ovarian function among adult CCSs. Methods: Anti-Müllerian hormone (AMH) levels served as a proxy for ovarian function in a discovery cohort of adult female CCSs, from the pan-European PanCareLIFE cohort (n = 743, age (years): median 25.8, interquartile range (IQR) 22.1–30.6). Using two additive genetic models in linear and logistic regression, nine genetic variants in three CYP450 enzymes were analyzed in relation to cyclophosphamide equivalent dose (CED) score and their impact on AMH levels. The main model evaluated the effect of the variant on AMH and the interaction model evaluated the modifying effect of the variant on the impact of CED score on log-transformed AMH levels. Results were validated, and meta-analysis performed, using the USA-based St. Jude Lifetime Cohort (n = 391, age (years): median 31.3, IQR 26.6–37.4). Results: CYP3A4*3 was significantly associated with AMH levels in the discovery and replication cohort. Meta-analysis revealed a significant main deleterious effect (Beta (95% CI): −0.706 (−1.11–−0.298), p-value = 7 × 10−4) of CYP3A4*3 (rs4986910) on log-transformed AMH levels. CYP2B6*2 (rs8192709) showed a significant protective interaction effect (Beta (95% CI): 0.527 (0.126–0.928), p-value = 0.01) on log-transformed AMH levels in CCSs receiving more than 8000 mg/m2 CED. Conclusions: Female CCSs CYP3A4*3 carriers had significantly lower AMH levels, and CYP2B6*2 may have a protective effect on AMH levels. Identification of risk-contributing variants may improve individualized counselling regarding the treatment-related risk of infertility and fertility preservation options.

BackgroundIncreased epigenetic age acceleration (EAA) in survivors of childhood cancer is associated with specific treatment exposures, unfavorable health behaviors, and presence of certain chronic health conditions. To better understand inter-individual variability, we investigated the genetic basis underlying EAA.MethodsGenome-wide association studies of EAA based on multiple epigenetic clocks (Hannum, Horvath, PhenoAge, and GrimAge) were performed. MethylationEPIC BeadChip array and whole-genome sequencing data were generated with blood-derived DNA from participants in the St. Jude Lifetime Cohort Study (discovery: 2138 pre-existing and 502 newly generated data, all survivors; exploratory: 282 community controls). Linear regression models were fit for each epigenetic age against the allelic dose of each genetic variant, adjusting for age at sampling, sex, and cancer treatment exposures. Fixed-effects meta-analysis was used to combine summary statistics from two discovery data sets. LD (Linkage disequilibrium) score regression was used to estimate single-nucleotide polymorphism (SNP)-based heritability.ResultsFor EAA-Horvath, a genome-wide significant association was mapped to theSELPgene with the strongest SNP rs732314 (meta-GWAS:β=0.57,P=3.30×10-11). Moreover, the stratified analysis of the association between rs732314 and EAA-Horvath showed a substantial heterogeneity between children and adults (meta-GWAS:β=0.97 vs. 0.51,I2=73.1%) as well as between survivors with and without chest/abdominal/pelvic-RT exposure (β=0.64 vs. 0.31,I2=66.3%). For EAA-Hannum, an association was mapped to theHLAlocus with the strongest SNP rs28366133 (meta-GWAS:β=0.78,P=3.78×10-11). There was no genome-wide significant hit for EAA-PhenoAge or EAA-GrimAge. Interestingly, among community controls, rs732314 was associated with EAA-Horvath (β=1.09,P=5.43×10-5), whereas rs28366133 was not associated with EAA-Hannum (β=0.21,P=0.49). The estimated heritability was 0.33 (SE=0.20) for EAA-Horvath and 0.17 (SE=0.23) for EAA-Hannum, but close to zero for EAA-PhenoAge and EAA-GrimAge.ConclusionsWe identified novel genetic variants in theSELPgene andHLAregion associated with EAA-Horvath and EAA-Hannum, respectively, among survivors of childhood cancer. The new genetic variants in combination with other replicated known variants can facilitate the identification of survivors at higher risk in developing accelerated aging and potentially inform drug targets for future intervention strategies among vulnerable survivors.

Progress in therapy has made survival into adulthood a reality for most children, adolescents, and young adults with a cancer diagnosis today. Notably, this growing population remains vulnerable to a variety of long-term therapy-related sequelae. Systematic ongoing follow-up of these patients is, therefore, important to provide for early detection of and intervention for potentially serious late-onset complications. In addition, health counseling and promotion of healthy lifestyles are important aspects of long-term follow-up care to promote risk reduction for physical and emotional health problems that commonly present during adulthood. Both general and subspecialty health care providers are playing an increasingly important role in the ongoing care of childhood cancer survivors, beyond the routine preventive care, health supervision, and anticipatory guidance provided to all patients. This report is based on the guidelines that have been developed by the Children’s Oncology Group to facilitate comprehensive long-term follow-up of childhood, adolescent, and young adult cancer survivors (www.survivorshipguidelines.org).

Background Among adult childhood cancer survivors, the relationship between race/ethnicity and health insurance status, as a contributor to disparities in healthcare utilization, is poorly understood. Methods We examined racial/ethnic-related disparities by insurance status in “forgoing needed medical care in the last year due to finances” using 3,964 adult childhood cancer survivors (3310 non-Hispanic/Latinx White, 562 non-Hispanic/Latinx Black, and 92 Hispanic/Latinx) participating in the St. Jude Lifetime Cohort Study (SJLIFE). Multivariable logistic regression analyses, guided by Andersen’s Healthcare Utilization Model, were adjusted for “predisposing” (age, sex, childhood cancer diagnosis, cancer treatment, surgery, and treatment era) and “need” (perceived health status) factors. Additional adjustment for income/education and chronic health conditions was considered. Results The risk of forgoing care was highest among non-Hispanic/Latinx Blacks and lowest among Hispanics/Latinxs for each insurance status. Among privately-insured survivors, relative to non-Hispanic/Latinx Whites, non-Hispanic/Latinx Blacks were more likely to forgo care (adjusted OR: 1.82, 95% CI: 1.30–2.54): this disparity remained despite additional adjustment for income/education (adjusted OR: 1.43, 95% CI: 1.01–2.01). In contrast, publicly-insured survivors, regardless of race/ethnicity, had similar risk of forgoing care as privately-insured non-Hispanic/Latinx Whites. All uninsured survivors had high risk of forgoing care. Additional adjustment for chronic health conditions did not alter these results. Conclusions The findings of this study show that provision of public insurance to all childhood cancer survivors may diminish racial/ethnic disparities in forgoing care that exist among the privately-insured and reduce the risk of forgoing care among uninsured survivors to that of privately-insured non-Hispanic/Latinx Whites. Key messages Providing publicly funded health insurance coverage to childhood cancer survivors can reduce disparities in forgoing medical care.

Background: Subsequent thyroid cancer (STC) is one of the most common malignancies in childhood cancer survivors. We aimed to evaluate the polygenic contributions to STC risk and potential utility in improving risk prediction. Methods: A polygenic risk score (PRS) was calculated from 12 independent SNPs associated with thyroid cancer risk in the general population. Associations between PRS and STC risk were evaluated among survivors from St. Jude Lifetime Cohort (SJLIFE) and were replicated in survivors from Childhood Cancer Survivor Study (CCSS). A risk prediction model integrating the PRS and clinical factors, initially developed in SJLIFE, and its performance were validated in CCSS. Results: Among 2,370 SJLIFE survivors with a median follow-up of 28.8 [interquartile range (IQR) = 21.9–36.1] years, 65 (2.7%) developed STC. Among them, the standardized PRS was associated with an increased rate of STC [relative rate (RR) = 1.57; 95% confidence interval (CI) = 1.24–1.98; P < 0.001]. Similar associations were replicated in 6,416 CCSS survivors, among whom 121 (1.9%) developed STC during median follow-up of 28.9 (IQR = 22.6–34.6) years (RR = 1.52; 95% CI = 1.25–1.83; P < 0.001). A risk prediction model integrating the PRS with clinical factors showed better performance than the model considering only clinical factors in SJLIFE (P = 0.004, AUC = 83.2% vs. 82.1%, at age 40), which was further validated in CCSS (P = 0.010, AUC = 72.9% vs. 70.6%). Conclusions: Integration of the PRS with clinical factors provided a statistically significant improvement in risk prediction of STC, although the magnitude of improvement was modest. Impact: PRS improves risk stratification and prediction of STC, suggesting its potential utility for optimizing screening strategies in survivorship care.

Background Survivors of childhood, adolescent and young adult (CAYA) cancer may develop treatment-induced chronic liver disease. Surveillance guidelines can improve survivors’ health outcomes. However, current recommendations vary, leading to uncertainty about optimal screening. The International Late Effects of Childhood Cancer Guideline Harmonization Group has developed recommendations for the surveillance of late hepatotoxicity after CAYA cancer. Methods Evidence-based methods based on the GRADE framework were used in guideline development. A multidisciplinary guideline panel performed systematic literature reviews, developed evidence summaries, appraised the evidence, and formulated recommendations on the basis of evidence, clinical judgement, and consideration of benefits versus the harms of the surveillance while allowing for flexibility in implementation across different health care systems. Results The guideline strongly recommends a physical examination and measurement of serum liver enzyme concentrations (ALT, AST, gGT, ALP) once at entry into long-term follow-up for survivors treated with radiotherapy potentially exposing the liver (moderate- to high-quality evidence). For survivors treated with busulfan, thioguanine, mercaptopurine, methotrexate, dactinomycin, hematopoietic stem cell transplantation (HSCT), or hepatic surgery, or with a history of chronic viral hepatitis or sinusoidal obstruction syndrome, similar surveillance for late hepatotoxicity once at entry into LTFU is reasonable (low-quality evidence/expert opinion, moderate recommendation). For survivors who have undergone HSCT and/or received multiple red blood cell transfusions, surveillance for iron overload with serum ferritin is strongly recommended once at long-term follow-up entry. Conclusions These evidence-based, internationally-harmonized recommendations for the surveillance of late hepatic toxicity in cancer survivors can inform clinical care and guide future research of health outcomes for CAYA cancer survivors.

BACKGROUND Limited data exist regarding left ventricular remodeling patterns observed in adult survivors of childhood cancer after therapy. METHODS Among 1190 adult survivors diagnosed with childhood cancer (median age at diagnosis, 9 years [interquartile range (IQR), 3.8-14.4 years]; age at evaluation, 35.6 years [IQR, 29.5-42.8 years]), treatment exposures included anthracyclines (n = 346), chest radiotherapy (n = 174), both (n = 245), or neither (n = 425). Prospective echocardiographic assessment compared survivors with 449 noncancer controls classified according to left ventricle geometric patterns. Associations between left ventricle geometric patterns and decreased exercise tolerance were assessed. RESULTS Overall, 28.2% of survivors (95% confidence interval [CI], 25.6%-30.8%) exhibited concentric remodeling, 2.4% (95% CI, 1.6%-3.5%) exhibited eccentric hypertrophy, and 1.1% (95% CI, 0.6%-1.9%) exhibited concentric hypertrophy. A greater proportion of survivors who received only chest radiotherapy (41%) had concentric remodeling compared with those who received only anthracyclines (24%), both (27%), or neither (27%; all P < .001), and all were greater than the proportions in noncancer controls (18%; all P < .05). Concentric remodeling was associated with radiation exposure, but not with anthracycline exposure, in multivariable models. Survivors who had concentric remodeling were more likely to have a maximal oxygen uptake peak

OBJECTIVE To examine the influence of the glycemic index (GI) of foods consumed after evening exercise on postprandial glycemia, metabolic and inflammatory markers, and nocturnal glycemic control in type 1 diabetes. RESEARCH DESIGN AND METHODS On two evenings (∼1700 h), 10 male patients (27 ± 5 years of age, HbA1c 6.7 ± 0.7% [49.9 ± 8.1 mmol/mol]) were administered a 25% rapid-acting insulin dose with a carbohydrate bolus 60 min before 45 min of treadmill running. At 60 min postexercise, patients were administered a 50% rapid-acting insulin dose with one of two isoenergetic meals (1.0 g carbohdyrate/kg body mass [BM]) matched for macronutrient content but of either low GI (LGI) or high GI (HGI). At 180 min postmeal, the LGI group ingested an LGI snack and the HGI group an HGI snack (0.4 g carbohdyrate/kg BM) before returning home (∼2300 h). Interval samples were analyzed for blood glucose and lactate; plasma glucagon, epinephrine, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α); and serum insulin, cortisol, nonesterified fatty acid, and β-hydroxybutyrate concentrations. Interstitial glucose was recorded for 20 h postlaboratory attendance through continuous glucose monitoring. RESULTS Following the postexercise meal, an HGI snack induced hyperglycemia in all patients (mean ± SD glucose 13.5 ± 3.3 mmol/L) and marked increases in TNF-α and IL-6, whereas relative euglycemia was maintained with an LGI snack (7.7 ± 2.5 mmol/L, P CONCLUSIONS Consuming LGI food with a reduced rapid-acting insulin dose following evening exercise prevents postprandial hyperglycemia and inflammation and provides hypoglycemia protection for ∼8 h postexercise; however, the risk of late nocturnal hypoglycemia remains.

Background Greater than one-half of children who are treated for acute lymphoblastic leukemia (ALL) develop ≥1 treatment-related medical conditions in their lifetime, many of which are known risk factors for diabetes mellitus. In the current study, the authors evaluated the prevalence and risk factors of diabetes mellitus among clinically assessed adult survivors of childhood ALL METHODS: The authors performed a retrospective evaluation of data from survivors of ALL and community controls who were enrolled in the St. Jude Lifetime Cohort Study between October 1, 2007, and June 30, 2016. Participants were adults with ≥10 years of survival of childhood ALL and community controls who completed clinical and laboratory evaluations. Data for the current analysis were abstracted from medical records. Exposures evaluated herein included chemotherapy and radiation exposures and medical history, including drug-induced diabetes mellitus. Results Of 1360 eligible adults who were ≥10-year survivors of childhood ALL, a total of 1044 completed the evaluations; these individuals had a mean age of 33.97±9.14 years and 50.86% were male. The 368 controls, 45.65% of whom were male, had a mean age of 35.33±10.21 years. Type 2 diabetes mellitus (T2DM) was found in approximately 7.47% of survivors and 3.80% of controls (odds ratio [OR], 2.07; 95% CI, 1.11-3.87). In adjusted models, among survivors, older age (OR, 1.05 for each additional year; 95% CI, 1.02-1.08), body mass index ≥30 kg/m2 (OR, 7.40; 95% CI, 2.61-20.97), and drug-induced diabetes mellitus occurring during ALL therapy (OR, 4.67; 95% CI, 2.53-8.61) were found to be associated with T2DM. Conclusions Adult survivors of childhood ALL are at an increased risk of T2DM. Adult survivors of childhood ALL who are of older age, with an overweight or obese body mass index, and/or who developed drug-induced diabetes mellitus during treatment should be closely monitored for T2DM during long-term follow-up.

BACKGROUND Survivors of childhood acute lymphoblastic leukemia (ALL) are at increased risk for both treatment-related exercise intolerance and neurocognitive deficits. This analysis aimed to identify the association between exercise intolerance and neurocognitive impairments in ALL survivors. METHODS Cardiopulmonary exercise testing, results from a 2-hour standardized neuropsychological assessment, and self-report questionnaires were obtained for 341 adult survivors of childhood ALL and 288 controls. Multivariable modeling was used to test associations between oxygen uptake at 85% estimated heart rate (rpkVO2 ) and neuropsychological test and self-reported questionnaire domains, adjusted for sex, age at diagnosis, cranial radiation, anthracycline, and methotrexate exposure and tobacco smoking status. RESULTS Compared with controls, survivors had worse rpkVO2 and performance on verbal intelligence, focused attention, verbal fluency, working memory, dominant/nondominant motor speed, visual-motor speed, memory span, and reading and math measures (all P

Background Optimal risk-based survivor health care includes surveillance for late effects and education targeted at reducing or preventing risky health behaviors. Understanding the reasons for a lack of risk-based follow-up care is essential. Methods Adult participants from the Childhood Cancer Survivor Study were surveyed about having a cancer-related visit in the past 2 years and the likelihood of having a cancer-related visit in the future. Additional factors thought to be related to the primary outcomes were also assessed. Results Nine hundred seventy-five survivors completed the survey. Twenty-seven percent (95% confidence interval [CI], 24%-30%) had a cancer-related medical visit in the previous 2 years, and 41% (95% CI, 38%-44%) planned to have such a visit within the next 2 years. The likelihood of having had a cancer-related visit within the last 2 years was higher among survivors assigning greater importance to these visits (relative risk [RR], 1.2; 95% CI, 1.1-1.3), perceiving greater susceptibility to health problems (RR, 1.2; 95% CI, 1.1-1.3), having a moderate to life-threatening chronic health problem related to their cancer (RR, 2.1; 95% CI, 1.7-2.7), seeing a primary care provider for a cancer-related problem (RR, 1.3; 95% CI, 1.0-1.6), having a cancer treatment summary (RR, 1.3; 95% CI, 1.0-1.6), and endorsing greater confidence in physicians' abilities to address questions and concerns (RR, 1.2; 95% CI, 1.0-1.3). Conclusions Educational interventions improving awareness of treatment history and susceptibility to cancer-related late effects and corresponding risk-based care are likely to be beneficial for survivors of childhood cancers.

PURPOSE The widely used, risk-based Lymphome Malin de Burkitt (LMB) chemotherapy regimen has improved survival rates for children with mature B-cell non-Hodgkin lymphoma (NHL); however, associated late effects remain understudied. We assessed late health outcomes after LMB treatment in the Childhood Cancer Survivor Study. PATIENTS AND METHODS Multivariable regression models compared chronic health conditions, health status, and socioeconomic and neurocognitive outcomes between survivors of NHL treated with the LMB regimen (n = 126), survivors of NHL treated with non-LMB regimens (n = 444), and siblings (n = 1,029). RESULTS LMB survivors were a median age of 10.2 years (range, 2.5 to 20.5 years) at diagnosis and 24.0 years (range, 10.3 to 35.3 years) at evaluation. Compared with siblings, LMB survivors were at increased risk for adverse health outcomes. However, survivors of NHL treated with LMB and non-LMB regimens did not differ with regard to risk of having any chronic health conditions, impaired health status, neurocognitive deficits, or poorer socioeconomic outcomes. Increased risk for the following specific neurologic conditions was observed in LMB survivors compared with non-LMB survivors: epilepsy (relative risk [RR], 15.2; 95% CI, 3.1 to 73.4); balance problems (RR, 8.9; 95% CI, 2.3 to 34.8); tremors (RR, 7.5; 95% CI, 1.9 to 29.9); weakness in legs (RR, 8.1; 95% CI, 2.5 to 26.4); severe headaches (RR, 3.2; 95% CI, 1.6 to 6.3); and prolonged arm, leg, or back pain (RR, 4.0; 95% CI, 2.2 to 7.1). The survivors from the group C LMB risk group (n = 50) were at the highest risk for these conditions; however, except for worse functional status (odds ratio, 2.7; 95% CI, 1.2 to 5.8), they were not at increased risk for other adverse health status or socioeconomic outcomes compared with non-LMB survivors. CONCLUSION Survivors treated with LMB and non-LMB regimens are largely comparable in late health outcomes except for excess neurotoxicity among LMB survivors. These data inform treatment efforts seeking to optimize disease control while minimizing toxicity.

PURPOSE The aim of the current study was to increase the uptake of screening mammography among high-risk women who were treated for a childhood cancer with chest radiotherapy. PATIENTS AND METHODS Two hundred four female survivors in the Childhood Cancer Survivor Study who were treated with chest radiotherapy with 20 Gy or greater, age 25 to 50 years, and without breast imaging in the past 24 months were randomly assigned 2:1 to receive a mailed informational packet followed by a tailored telephone-delivered brief motivational interview (intervention) versus an attention control. Primary outcome was the difference in the proportion of participants who completed a screening mammogram by 12 months as evaluated in an intent-to-treat analysis. Stratum-adjusted relative risk (RR) and 95% CI were estimated using the Cochran-Mantel-Haenszel method. Secondary outcomes included the completion of screening breast magnetic resonance imaging (MRI) and barriers to screening and moderating factors. RESULTS Women in the intervention group were significantly more likely than those in the control group to report a mammogram (45 [33.1%] of 136 v 12 [17.6%] of 68; RR, 1.9; 95% CI, 1.1 to 3.3). The intervention was more successful among women age 25 to 39 years (RR, 2.2; 95% CI, 1.1 to 4.7) than among those age 40 to 50 years (RR, 1.4; 95% CI, 0.6 to 3.2). The proportion of women who reported a breast MRI at 12 months was similar between the two groups: 16.2% (intervention) compared with 13.2% (control; RR, 1.2; 95% CI, 0.6 to 2.5). Primary barriers to completing a screening mammogram and/or breast MRI included lack of physician recommendation, deferred action by survivor, cost, and absence of symptoms. CONCLUSION Use of mailed materials followed by telephone-delivered counseling increased mammography screening rates in survivors at high risk for breast cancer; however, this approach did not increase the rate of breast MRI. Cost of imaging and physician recommendation were important barriers that should be addressed in future studies.

The NCCN Guidelines for Survivorship provide screening, evaluation, and treatment recommendations for consequences of cancer and cancer treatment to aid healthcare professionals who work with survivors of adult-onset cancer. Guidance is also provided to help promote physical activity, weight management, and proper immunizations in survivors and to facilitate care coordination to ensure that all needs are addressed. These NCCN Insights summarize some of the topics discussed by the NCCN Survivorship Panel during the 2019 update of the guidelines, including the survivorship population addressed, ways to improve care coordination, and pain management.

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). 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. 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

Background and purpose The use of radiotherapy (RT) for pediatric patients with Hodgkin lymphoma (HL) experiencing disease progression or recurrence (15%) is controversial. We report treatment patterns and outcomes for pediatric patients with refractory/recurrent HL (rrHL) treated with curative-intent RT. Materials and methods Forty-six patients with rrHL treated with salvage RT at our institution were identified. All received risk-adapted, response-based frontline therapy and were retrieved with cytoreductive regimens followed by RT to failure sites, with or without autologous hematopoietic cell transplantation (AHCT). Cumulative incidence (CIN) of local failure (LF) and survival were estimated after salvage RT and regression models determined predictors of LF after salvage RT. Results RT was administered as part of frontline therapy in 70% of patients, omitted for early response assessment in 13%, or deferred for primary progression in 17%. AHCT was omitted in 20% of patients. Median initial and salvage dose/site were 25.5 Gy and 30.6 Gy, respectively. Eight patients experienced progression. Two died without progression (median follow-up from salvage RT = 3.8 years). The 5-year CIN of LF after salvage RT was 17.7% (95% confidence interval [CI], 8.2–30.2%). The 5-year freedom from subsequent treatment failure and overall survival (OS) was 80.1% (95% CI, 69.2–92.6%) and 88.5% (95% CI, 79.5–98.6%), respectively. Inadequate response to salvage systemic therapy (p = 0.048) and male sex (p = 0.049) were significantly associated with LF after salvage RT. Conclusion rrHL is responsive to salvage RT, with low LF rates after moderate doses. OS is excellent, despite refractory disease. Initial salvage therapy response predicts subsequent LF.

Background Motivational interviewing (MI) can increase health-promoting behaviors and decrease health-damaging behaviors. However, MI is often resource intensive, precluding its use with people with limited financial or time resources. Mobile health–based versions of MI interventions or technology-delivered adaptations of MI (TAMIs) might increase reach. Objective We aimed to understand the characteristics of existing TAMIs. We were particularly interested in the inclusion of people from marginalized sociodemographic groups, whether the TAMI addressed sociocontextual factors, and how behavioral and health outcomes were reported. Methods We employed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for scoping reviews to conduct our scoping review. We searched PubMed, CINAHL, and PsycInfo from January 1, 1996, to April 6, 2022, to identify studies that described interventions incorporating MI into a mobile or electronic health platform. For inclusion, the study was required to (1) describe methods/outcomes of an MI intervention, (2) feature an intervention delivered automatically via a mobile or electronic health platform, and (3) report a behavioral or health outcome. The exclusion criteria were (1) publication in a language other than English and (2) description of only in-person intervention delivery (ie, no TAMI). We charted results using Excel (Microsoft Corp). Results Thirty-four studies reported the use of TAMIs. Sample sizes ranged from 10 to 2069 participants aged 13 to 70 years. Most studies (n=27) directed interventions toward individuals engaging in behaviors that increased chronic disease risk. Most studies (n=22) oversampled individuals from marginalized sociodemographic groups, but few (n=3) were designed specifically with marginalized groups in mind. TAMIs used text messaging (n=8), web-based intervention (n=22), app + text messaging (n=1), and web-based intervention + text messaging (n=3) as delivery platforms. Of the 34 studies, 30 (88%) were randomized controlled trials reporting behavioral and health-related outcomes, 23 of which reported statistically significant improvements in targeted behaviors with TAMI use. TAMIs improved targeted health behaviors in the remaining 4 studies. Moreover, 11 (32%) studies assessed TAMI feasibility, acceptability, or satisfaction, and all rated TAMIs highly in this regard. Among 20 studies with a disproportionately high number of people from marginalized racial or ethnic groups compared with the general US population, 16 (80%) reported increased engagement in health behaviors or better health outcomes. However, no TAMIs included elements that addressed sociocontextual influences on behavior or health outcomes. Conclusions Our findings suggest that TAMIs may improve some health promotion and disease management behaviors. However, few TAMIs were designed specifically for people from marginalized sociodemographic groups, and none included elements to help address sociocontextual challenges. Research is needed to determine how TAMIs affect individual health outcomes and how to incorporate elements that address sociocontextual factors, and to identify the best practices for implementing TAMIs into clinical practice.

The genetic etiology for Hodgkin lymphoma (HL) has been investigated with findings reported in both human leukocyte antigens (HLA) and non-HLA genomic regions. However, results of genetic association studies that focus on HL developed among children and adolescent individuals are limited. Given the historically high survival rate, it is reasonable to leverage available genetic data for survivors of childhood/adolescent HL for this investigation. Utilizing existing data from the St. Jude Lifetime Cohort, the Childhood Cancer Survivor Study (CCSS) original cohort and CCSS expansion cohort, we performed a fixed-effects meta-analysis of three genome-wide association studies for a total of 1,286 HL cases, 6,824 other childhood cancer cases and 373 non-cancer controls, all of whom are of European ancestry. Three independent SNPs in the HLA locus (rs28383311, Odds Ratio [OR] = 1.80, P = 2.14×10-21; rs3129198, OR = 1.52, P = 2.05×10-14; rs3129890, OR = 1.51, P = 6.21×10-13) were identified using step-wise conditional logistic regression. HLA SNP rs28383311 had a moderate correlation (r2 = 0.46) with rs2858870 reported previously by Cozen et al. (Blood, 2012) in the HLA-DRA gene region in adolescent/young adults onset HL. HLA SNP rs3129198 had a perfect correlation (r2 = 1.0) with rs2281389 (HLA-DPB1) reported previously by Moutsianas et al. (Blood, 2011) in mostly adults-onset HL. In contrast, SNP rs3129890 had a low correlation (r2 = 0.15) with rs2395185 (HLA-DRA) reported previously by Urayama et al. (JNCI, 2012) in HL cases diagnosed across a wide age range between 16 and 80 years old. Our analysis also identified additional SNPs for non-HLA loci at genome-wide significance level including: 1) rs1432297 (OR = 1.30, P = 2.5×10-8), which is in moderate correlation (r2=0.52) with previously reported rs1432295 (REL); 2) rs13279159 (OR = 1.32, P = 1.7×10-8), which is in high correlation (r2=0.75) with previously reported rs2019960 (PVT1); and 3) rs3824662 (OR = 1.52, P = 3.9×10-10), which had a high correlation (r2 = 0.91) with previously reported rs3781093 (GATA3). In addition, a novel uncommon SNP with a large effect size (rs117361561, OR = 1.95, P = 2.50×10-8, minor allele frequency = 0.02) was identified and mapped to PDGFD, a plausible gene for HL susceptibility. Twelve out 18 (67%) previously reported genome-wide significant non-HLA SNPs were replicated with P < 0.05 based on our meta-analysis. By analyzing early onset HL within pediatric and adolescent age range, we further dissected the associations in HLA locus by replicating three independent SNPs. We also found a novel non-HLA locus and replicated the majority of previous findings in the non-HLA region, suggesting mostly overlapping as well as potentially unique genetic etiology for HL risk across different ages of onset.

Survivors of childhood cancer are at risk for a spectrum of adverse outcomes including hematological malignancies and cardiovascular diseases, which in other populations have been associated with clonal hematopoiesis (CH), an age-related clonal expansion of hematopoietic stem cells. Here we present the first comprehensive CH analysis including 2,872 pediatric cancer survivors from the St. Jude Lifetime Cohort (median follow-up of 26 years from cancer diagnosis; median age of 31 years at blood draw) using deep sequencing (10,000 ×) over 39 CH genes on DNA derived from peripheral blood. As a comparison group, 324 age-, sex- and race/ethnicity-frequency-matched community controls (median age of 35 years at blood draw) were also analyzed. To detect rare CH variants, a machine-learning approach was applied, which characterized true variants as outliers in a genomic context-specific error profile. Digital droplet PCR validation was performed for 543 variants (323 positive [allele frequency: median 0.003, range 0.001 to 0.255] and 220 negative) out of 1,450 putative variants. The 907 untested variants were inferred using the 543 experimentally validated variants’ status as a training set. Analyses considered mutation status by the 555 positive variants and clinical data including age, sex, and detailed cancer treatment exposures. CH was detected in 15% (95% Confidence Interval (CI): 13.7 to 16.3) of survivors and 8.6% (95% CI: 5.6 to 11.7) of controls in an age-dependent manner: 10.6% (survivors) vs. 6.3% (controls) for ages in year 18 - 29; 13.5% vs. 5.8% for 30 - 39; 26.3% vs. 13.2% for 40 - 49; 28.1% vs. 17.2% for > 50. We also observed that the alterations in DNMT3A, TP53, STAT3, KRAS and TET2 became more prevalent as the survivors aged: combined proportion for the 5 genes, 61% for ages in year < 30; 72% for 30 - 40; 77% for 40 - 50; 87% for > 50. Analysis of longitudinal samples available for 73 survivors with 180 time points (median interval 4.6 years [range: 2.07 to 8.0 years]) confirmed that clones with these gene mutations had a higher growth rate than those without (p=0.034), suggesting fitness advantages in hematopoietic stem cell context. Multivariable analysis adjusted for treatment indicated that CH development is associated with cumulative dose of alkylating agents (Odds Ratio (OR) for 1st tertile 1.77 [95% CI: 1.22 to 2.57], 2nd tertile 2.72 [95% CI: 1.83 to 4.04], and 3rd tertile 2.92 [95% CI: 2.03 to 4.02], relative to the unexposed) and estimated radiotherapy-dose to active bone marrow (OR for 1st tertile 0.98 [95% CI: 0.68 to 1.40], 2nd tertile 1.06 [0.77 to 1.47], and 3rd tertile 1.57 [1.15 to 2.14], relative to the unexposed), supporting the hypothesis that CH development in survivors is primarily driven by prior therapy. This study identified accelerated CH development in pediatric cancer survivors, which may represent an important genomic biomarker predictive of future adverse health risks.

Epigenetic studies of blood lipid traits have identified genes underlying lipid metabolism in the general population. However, investigation of this association has not been conducted in survivors of childhood cancer, a population with a much higher burden of dyslipidemia and other cardiometabolic conditions due to exposures of genotoxic cancer therapies. We performed epigenome-wide association studies (EWAS) to identify blood DNA methylation (DNAm) 5’-cytosine-phosphate-guanine-3′ (CpGs) associated with lipid concentrations, including high-density lipoprotein (HDL), low-density lipoprotein (LDL), total cholesterol (TC), and triglycerides (TG), for childhood cancer survivors from the St. Jude Lifetime (SJLIFE) cohort. DNAm was generated with blood derived DNA using Illumina MethylationEPIC BeadChip array. Adjusted M-value of DNAm for each CpG was calculated based on a linear regression of M-value against a set of covariates, including sex, age at DNA sampling, leukocyte subtype proportions, top four significant genetic principal components, and top four methylation principal components. In the exposure EWAS, a linear regression model was used for lipid levels prior to DNA sampling as an exposure variable and DNAm as an outcome variable, adjusting for cancer treatments, age at lipid measurement, BMI, cigarette smoking and lipid lowering medicine use. In the outcome EWAS, a linear regression model was used for DNAm as an exposure variable and lipid levels after DNA sampling as outcome variables, adjusting for cancer treatments, age at lipid measurement, BMI, smoking, lipid lowering medicine use, lipid levels measured at DNA sampling, age at DNA sampling, and polygenic risk score for specific lipid levels. Among survivors of European ancestry (N=2052), we identified 43 significant CpGs (P50) and lipid outcomes (106/111 with I2>50). Additionally, no overlap between CpGs associated with lipid exposures and lipid outcomes suggests that the DNAm levels of these CpGs could be either the cause or consequence of lipid levels. Examination of the EWAS catalog and recent literature, suggests that most of the lipid associated CpGs identified in our study are novel. Blood lipid associated CpGs may be epigenetic biomarkers for identification of survivors with higher risk of dyslipidemia and may inform potential drug targets for future interventions.

12095 Background: Survivors of childhood cancer are at increased risk for early development of CHCs, including metabolic syndrome (MetS), low bone mineral density (LBMD), and gastrointestinal (GI) disease. Dietary modification is often recommended for prevention and/or treatment of these CHCs in non-cancer populations. However, associations between diet quality and severity of CHCs in adult survivors of childhood cancer are not well known. Methods: Adult survivors (≥10 years post-diagnosis) of childhood cancer who completed a clinical evaluation and Block Food Frequency Questionnaire were included. Diet quality was estimated using the Mediterranean diet score (aMED), with scores ranging from 0 to 9 (increased scores represent higher adherence to diet). CHCs were graded (modified CTCAE) and classified as “low” (grade ≤1 for LBMD and GI; grade ≤2 for MetS) or “high” (grade 2-4 for LBMD and GI; grade 3-4 for MetS). A multivariable linear regression model was used to estimate the mean aMED score by “low” or “high” disease category, with adjustment for age at evaluation, sex, race, education, total energy intake, adjusted BMI, physical activity, smoking, and alcohol consumption. Results: 2,822 survivors of childhood cancer (52.4% male, 83.1% non-Hispanic white) were included. The most prevalent diagnosis was acute lymphoblastic leukemia (34.1%). Time from primary diagnosis was 24.2±8.5 years and age at recruitment was 32.5±8.7 years. Lower adherence to aMED diet was associated with “high” MetS and LBMD, but not GI disease. See the Table for aMED multivariate-adjusted diet quality scores by CHC. Conclusions: In this cross-sectional analysis, MetS and LBMD were associated with poor adherence to the aMED diet. Although longitudinal investigation of associations between diet quality and CHCs in survivors of childhood cancer are needed to determine causal association between diet quality and CHCs in childhood cancer survivors, dietary interventions in early or late cancer survivors may help prevent development or progression of specific treatment related chronic conditions.

10051 Background: Chronic health conditions are prevalent among adult survivors of childhood cancer. The impact of health on maintaining full-time (FT) employment, a common indicator of socioeconomic independence, has not been studied in this population. Methods: Self-reported employment status (FT, part-time [PT], unemployed [any reason], not in labor force) was assessed at two timepoints (2002-04 [T1] and 2015-16 [T2]) in adult (≥25y old) survivors of childhood cancer diagnosed between 1970-86. Sex-stratified Poisson regression, adjusted for race and ages at diagnosis and T2, was used to study associations between timing and severity of chronic health conditions (graded per the CTCAE v4.03) and transitions from FT to PT or unemployed. Results: Survivors employed FT at T1 (males=1712, median age [min-max]: 34y [25-53]; females=1337, 33y [25-53]) who reported employment status at T2 were included. At T2 (median time from T1 11.5y [9.4-13.8]), 83% males and 70% females remained employed FT, but 4% and 10% transitioned to PT, and 11% and 12% to unemployed (additional 2% and 8% left the labor force), respectively. Male and female survivors with grade 2 or 3-4 neurologic conditions acquired before T1 or between T1-T2 were at a higher risk of moving from FT to PT or unemployed compared to those with grade 0-1 conditions. Males and females with grade 3-4 respiratory conditions prior to T1 and cardiac and musculoskeletal conditions acquired between T1-T2 were also at higher risk for moving to PT or unemployed (Table). Additional predictors for males included grade 2 vision (before T1 RR 2.3, 95% CI 1.5-3.3; between T1-T2 RR 1.7, 95% CI 1.1-2.7) and endocrine (before T1 RR 1.4, 95% CI 1.1-1.9; between T1-T2 RR 1.7, 95% CI 1.3-2.3) conditions. Conclusions: A substantial portion of adult survivors of childhood cancer with health conditions of varying severity leave FT employment. Increased awareness of all stakeholders may facilitate access to clinical counseling and occupational provisions for flexible and supportive work accommodations to reduce work-related barriers for childhood cancer survivors.

10014 Background: The impact ofmodifiable lifestyle and cardiovascular risk factors (CVRFs) on risk for late mortality in adult survivors of childhood cancer is not well established. Methods: All-cause and health-related late (>5 years from cancer diagnosis) mortality (HRM; excludes death from primary cancer and external causes) were evaluated in five-year survivors diagnosed

10052 Background: Among survivors exposed to anthracycline or chest radiation (RT) who have an ejection fraction (EF) of ≥50%, the utility of GLS and NT-proBNP to identify survivors who are at highest risk for future CM is unknown. Methods: Survivors participating in the St. Jude Lifetime Cohort, ≥5 years from cancer diagnosis and at risk for CM per the International Guideline Harmonization Group (IGHG), underwent baseline surveillance echocardiography. A baseline GLS and NT-proBNP was also performed for survivors with an EF ≥50%. Multivariable Cox regression models estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for risk of CM (graded per modified Common Terminology Criteria for Adverse Events v4.0) based on abnormal baseline GLS (≥ -18) and/or NT-proBNP (>age-sex-specific 97.5th percentiles) adjusted for age at baseline assessment, age at diagnosis, sex, race, hypertension, diabetes, obesity, and IGHG risk group (Table footnote). Results: Among 1598 at-risk survivors (median age 35.1, range 9.4-68.8 years), all had GLS and 1110 NT-proBNP at baseline. 165 (10.3%) developed CM ≥ grade 2 at a median follow-up of 5.2 (0.7-10.0) years. IGHG moderate- and high-risk survivors exposed to anthracyclines were at increased risk of CM at follow-up if both baseline GLS and NT-proBNP were abnormal (HR=3.4, 95% CI: 1.9-5.8; Table) or GLS was abnormal and NT-proBNP not assessed (HR=3.8, 95% CI: 2.0-7.2), or when GLS was normal and NT-proBNP was abnormal (HR=1.9, 95% CI: 1.1-3.4). Abnormal GLS and/or NT-proBNP were not associated with increased risk of CM in IGHG low-risk survivors or in those defined as moderate- to high-risk due to chest RT only. Conclusions: Among long-term survivors of childhood cancer exposed to >100 mg/m2 anthracycline, abnormal GLS and NT-proBNP identified those survivors at increased risk of future CM despite an EF ≥50% on surveillance echocardiography. Conditional surveillance strategies utilizing GLS and NT-proBNP may benefit moderate- to high-risk survivors. [Table: see text]

10020 Background: Survivors of pediatric cancer, including those without CNS-directed treatment, are at risk of neurocognitive impairment and peripheral or autonomic neuropathies; conditions that co-occur in non-cancer populations. Using the St. Jude Lifetime Cohort, we investigated associations between these sequelae to inform contributors to long-term cancer-related neurocognitive impairment. Methods: Clinically assessed survivors of pediatric cancer (N=2,138, mean age 31 [SD 13], 23[11] years from diagnosis, 51% male) not treated with CNS-directed therapy completed neurocognitive testing. Modified total neuropathy score peripheral sensory and motor subscales were combined with functional tasks and severity graded using a modified NCI CTCAE. Cardiac autonomic neuropathy was defined as impaired heart rate reserve (th percentile) associated with grade 2+ sensory, motor or autonomic neuropathy. Path analysis examined if pain with daily interference mediated associations between motor or sensory neuropathy and neurocognitive impairment. Results: 838 (39%) survivors had autonomic, 115 (5.4%) had motor and 162 (7.6%) had sensory neuropathy. Compared to those with no neuropathy, survivors with motor or sensory neuropathy had a higher risk of impairment in sustained attention, visual-motor processing speed, short- and long-term memory, and executive function (Table, p’s

10050 Background: Childhood cancer survivors are at risk for shortened lifespan. Projections of life expectancy (LE) by diagnosis can provide benchmarks for assessing improvements over time. Methods: We developed a simulation model to project risk for common, life-threatening chronic health conditions (CHCs; heart failure, myocardial infarction, valvular disease, stroke, secondary breast cancer, colorectal cancer, glial tumors, sarcomas) and excess mortality among 5-year survivors, based on patient characteristics (sex, age at diagnosis, diagnosis) and treatment exposures (chemotherapy, radiation dose). Risk was estimated using statistical models and Childhood Cancer Survivor Study data. Age-related CHC risks (SEER, NHLBI) and competing mortality (CDC Wonder) were based on national databases. We used model calibration to identify parameter sets that generated outcomes consistent with observed data. Model outcomes included conditional LE and 10-year survival probability at age 40. For comparisons to the general population, we simulated age-, sex-, and diagnosis year-matched individuals who faced only competing mortality rates. Results: Among a cohort representative of the CCSS (mean diagnosis age, 7.4 yrs), compared to the general population, the gap in LE among survivors diagnosed in the 1970s vs. 1990s decreased from 17 yrs (25%) to 11 yrs (17%). Changes in LE among survivors diagnosed in the 1990s vs. 1970s varied by diagnosis, with leukemia, lymphoma, and CNS tumor survivors estimated to live an additional 8 to 11 yrs (Table). In contrast, considerably smaller gains were estimated for sarcoma and renal tumor survivors (1–3 yrs) and a loss for neuroblastoma (-3 yrs). Among survivors who reached age 40, the probability of surviving an additional 10 years increased from 89% to 92% between 1970s vs. 1990s, with the greatest gains for lymphoma and CNS tumors. Conclusions: Although temporal changes in pediatric oncology are projected to result in LE gains among survivors, considerable variation is projected across diagnoses. These findings highlight the uneven success of improving treatments for all cancers. [Table: see text]

e24147 Background: Psychosocial late effects of childhood cancer are often studied in isolation despite high rates of co-morbidity. We examined patterns of psychosocial morbidity and their associations with subsequent chronic health conditions, quality of life, and mortality in adult survivors of childhood cancer. Methods: St. Jude Lifetime Cohort participants (n = 4,009; median[range] 30.6[18.0-64.8] years of age; 20.4[5.5-52.3] years from diagnosis; 51% female) completed baseline questionnaires. Latent class analysis characterized psychosocial morbidity using 18 individual indicators across four domains: functional independence (e.g., independent living), emotional health (e.g., depressive symptoms), health behaviors (e.g., alcohol use), and socioeconomic status (e.g., employment). Generalized linear models, adjusted for age, sex, and race/ethnicity, examined longitudinal associations between class membership at cohort entry and persistent/new onset Grade 2-4 chronic health conditions from baseline to follow-up (n = 2,355, median f/u = 5.8 years). In separate adjusted models, associations with persistently poor/worsening quality of life at follow-up [SF-36 t-score
