Background Neurocognitive impairments are sequelae of childhood cancer treatment, however little guidance is given to clinicians on common phenotypes of impairment or modifiable risk factors that could lead to personalized interventions in survivorship. Methods Standardized clinical testing of neurocognitive function was conducted in 2958 (74.1%) eligible survivors, who were at least 5 years postdiagnosis and aged older than 18 years, and 477 community controls. Impairment was examined across 20 measures, and phenotypes were determined by latent class analysis. Multinomial logistic regression was used to estimate risk for phenotype, predicted by cancer diagnosis and treatment exposures, chronic health conditions, and lifestyle, adjusted for sex and age. Associations between phenotypes and social attainment were examined. Results Five neurocognitive phenotypes were identified in survivors (global impairment 3.7%, impaired attention 5.0%, memory impairment 7.2%, processing speed and executive function impairment 9.3%, no impairment 74.8%). Risk of global impairment was associated with severe chronic health condition burden (odds ratio [OR] = 20.17, 95% confidence interval [CI] = 11.41 to 35.63) including cerebrovascular disease (OR = 14.5, 95% CI = 5.47 to 38.44) and cerebrovascular accident (OR = 14.7, 95% CI = 7.50 to 26.40). Modifiable risk factors, such as quitting smoking, reduced risk for global impairment (OR = 0.21, 95% CI = 0.06 to 0.66). Low physical activity increased risk for global impairment (OR = 4.54, 95% CI = 2.86 to 7.21), attention impairment (OR = 2.01, 95% CI = 1.41 to 2.87), processing speed and executive function impairment (OR = 1.90, 95% CI = 1.46 to 2.48), and memory impairment (OR = 2.09, 95% CI = 1.54 to 2.82). Conclusions Results support the clinical utility of neurocognitive phenotyping to develop risk profiles and personalized clinical interventions, such as preventing cerebrovascular disease in anthracycline-treated survivors by preventing hypercholesterolemia, smoking, and sedentary lifestyle, to reduce the risk for global impairment.

Background Childhood cancer survivors are at high risk for morbidity and mortality and poor patient-reported outcomes, typically health-related quality of life (HRQOL). However, associations between DNA methylation–based aging biomarkers and HRQOL have not been evaluated. Methods DNA methylation was generated with Infinium EPIC BeadChip on blood-derived DNA (median for age at blood draw = 34.5 years, range = 18.5-66.6 years), and HRQOL was assessed with age at survey (mean = 32.3 years, range = 18.4-64.5 years) from 2206 survivors in the St Jude Lifetime Cohort. DNA methylation–based aging biomarkers, including epigenetic age using multiple clocks (eg, GrimAge) and others (eg, DNAmB2M: beta-2-microglobulin; DNAmADM: adrenomedullin), were derived from the DNAm Age Calculator (https://dnamage.genetics.ucla.edu). HRQOL was assessed using the Medical Outcomes Study 36-Item Short-Form Health Survey to capture 8 domains and physical and mental component summaries. General linear models evaluated associations between HRQOL and epigenetic age acceleration (EAA; eg, EAA_GrimAge) or other age-adjusted DNA methylation–based biomarkers (eg, ageadj_DNAmB2M) after adjusting for age at blood draw, sex, cancer treatments, and DNA methylation–based surrogate for smoking pack-years. All P values were 2-sided. Results Worse HRQOL was associated with greater EAA_GrimAge (physical component summaries: β = -0.18 years, 95% confidence interval [CI] = -0.251 to -0.11 years; P  = 1.85 × 10−5; and 4 individual HRQOL domains), followed by ageadj_DNAmB2M (physical component summaries: β = -0.08 years, 95% CI = -0.124 to -0.037 years; P  = .003; and 3 individual HRQOL domains) and ageadj_DNAmADM (physical component summaries: β = -0.082 years, 95% CI = -0.125 to -0.039 years; P  = .002; and 2 HRQOL domains). EAA_Hannum (Hannum clock) was not associated with any HRQOL. Conclusions Overall and domain-specific measures of HRQOL are associated with DNA methylation measures of biological aging. Future longitudinal studies should test biological aging as a potential mechanism underlying the association between poor HRQOL and increased risk of clinically assessed adverse health outcomes.

Background Early efforts at risk-adapted therapy for neuroblastoma are predicted to result in differential late effects; the magnitude of these differences has not been well described. Methods Late mortality, subsequent malignant neoplasms (SMNs), and severe/life-threatening chronic health conditions (CHCs), graded according to CTCAE v4.03, were assessed among 5-year Childhood Cancer Survivor Study (CCSS) survivors of neuroblastoma diagnosed 1987-1999. Using age, stage at diagnosis, and treatment, survivors were classified into risk groups (low [n = 425]; intermediate [n = 252]; high [n = 245]). Standardized mortality ratios (SMRs) and standardized incidence ratios (SIRs) of SMNs were compared with matched population controls. Cox regression models estimated hazard ratios (HRs) and 95% confidence intervals for CHC compared with 1029 CCSS siblings. Results Among survivors (49.8% male; median age = 21 years, range = 7-42; median follow-up = 19.3 years, range = 5-29.9), 80% with low-risk disease were treated with surgery alone, whereas 79.1% with high-risk disease received surgery, radiation, chemotherapy ± autologous stem cell transplant (ASCT). All-cause mortality was elevated across risk groups (SMRhigh = 27.7 [21.4-35.8]; SMRintermediate = 3.3 [1.7-6.5]; SMRlow = 2.8 [1.7-4.8]). SMN risk was increased among high- and intermediate-risk survivors (SIRhigh = 28.0 [18.5-42.3]; SIRintermediate = 3.7 [1.2-11.3]) but did not differ from the US population for survivors of low-risk disease. Compared with siblings, survivors had an increased risk of grade 3-5 CHCs, particularly among those with high-risk disease (HRhigh = 16.1 [11.2-23.2]; HRintermediate = 6.3 [3.8-10.5]; HRlow = 1.8 [1.1-3.1]). Conclusion Survivors of high-risk disease treated in the early days of risk stratification carry a markedly elevated burden of late recurrence, SMN, and organ-related multimorbidity, whereas survivors of low/intermediate-risk disease have a modest risk of late adverse outcomes.

Background Hearing loss is prevalent following ototoxic therapy for childhood cancer. Associations between hearing loss, self-perceived hearing handicap, and functional outcomes have not been examined in survivors. Methods Adult survivors treated with platinum or head and neck radiotherapy with hearing loss were recruited. A total of 237 survivors (median age at survey = 37.0 years [range = 30.0-45.0 years]; median = 29.1 years [range = 22.4-35.0 years] since diagnosis; median = 4.0 years [range = 2.9-7.7 years] from last audiogram to survey) completed the Hearing Handicap Inventory for Adults and questionnaires on social and emotional functioning and hearing aid use. Hearing loss severity was defined according to Chang criteria. Multivariable logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs) for associations between hearing loss, hearing handicap, functional outcomes, and hearing aid use with adjustment for sex, race, age at hearing loss diagnosis, and age at survey. Results Two-thirds of survivors had severe hearing loss, which was associated with increased likelihood of hearing handicap (mild-moderate handicap: OR = 2.72, 95% CI = 1.35 to 5.47; severe handicap: OR = 5.99, 95% CI = 2.72 to 13.18). Survivors with severe hearing handicap had an increased likelihood of social isolation (OR = 8.76, 95% CI = 3.62 to 21.20), depression (OR = 9.11, 95% CI = 3.46 to 24.02), anxiety (OR = 17.57, 95% CI = 3.77 to 81.84), reduced personal income (OR = 2.82, 95% CI = 1.46 to 5.43), and less than full-time employment (OR = 2.47, 95% CI = 1.30 to 4.70). Survivors who did not use a recommended hearing aid were twice as likely to have less than full-time employment (OR = 2.26, 95% CI = 1.10 to 4.61) and reduced personal income (OR = 2.24, 95% CI = 1.08 to 4.63) compared with survivors who wore a hearing aid. Conclusion Self-perceived hearing handicap beyond measured hearing loss is associated with reduced functional outcomes. Assessment of hearing handicap may facilitate targeted interventions in adult survivors with hearing loss. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Background: We aimed to characterize premature aging as an accumulation of deficits in survivors of pediatric cancer compared to community controls and examine associations with host/treatment factors, neurocognition, and mortality.Methods: Pediatric cancer survivors (N = 4,000, median age 28.6 [IQR 23-35], 20 [15-27] years post-diagnosis) and community controls (N = 638, median age 32 [25-40]) completed clinical assessments, questionnaires, and were followed for mortality through April 30th, 2020 (mean [SD] follow-up 7.0 [3.4] years). A deficit accumulation index (DAI) score was calculated from 44 aging-related items including: self-reported daily function, psychosocial symptoms, and health conditions. Items were weighted from 0 (absent) to 1 (present/most severe), summed and divided by the total yielding a ratio (higher=more deficits). Scores <0.20 are robust and 0.06 is a clinically meaningful difference. Linear regression compared the DAI in survivors and controls with an age*survivor/control interaction. Logistic regression and Cox-proportional hazards estimated the risk of neurocognitive impairment and death. Models were minimally adjusted for age, sex, and race andethnicity.Results: The adjusted mean DAI among survivors at age 30 years was 0.16 corresponding to age 63 in controls (33 years premature aging; β = 0.07 95%CI 0.06-0.08; p<.001). Cranial/abdominal radiation, alkylators, platinum, and neurosurgery were associated with worse DAI (p's≤.001). Higher scores were associated with increased risk of neurocognitive impairment in all domains (p's<.001) and increased risk of death (DAI 0.20-0.35 HR = 2.80, 95%CI 1.97-3.98; DAI ≥0.35 HR = 5.08, 95%CI 3.52-7.34).Conclusion:  Pediatric cancer survivors experience significant premature aging. The DAI may be used to identify survivors at greatest risk of poor health outcomes. [ABSTRACT FROM AUTHOR]

Background: Children with B-acute lymphoblastic leukemia (B-ALL) are at risk for chemotherapy-induced peripheral neuropathy (CIPN). Children's Oncology Group AALL0932 randomized reduction in vincristine and dexamethasone (every 4 weeks vs 12 weeks during maintenance in the average-risk subset of National Cancer Institute standard-B-ALL (SR AR B-ALL). We longitudinally measured CIPN, overall and by treatment group.Methods: AALL0932 standard-B-ALL patients aged 3 years and older were evaluated at T1-T4 (end consolidation, maintenance month 1, maintenance month 18, 12 months posttherapy). Physical and occupational therapists (PT/OT) measured motor CIPN (hand and ankle strength, dorsiflexion and plantarflexion range of motion), sensory CIPN (finger and toe vibration and touch), function (dexterity [Purdue Pegboard], and walking efficiency [Six-Minute Walk]). Proxy-reported function (Pediatric Outcome Data Collection Instrument) and quality of life (Pediatric Quality of Life Inventory) were assessed. Age- and sex-matched z scores and proportion impaired were measured longitudinally and compared between groups.Results: Consent and data were obtained from 150 participants (mean age = 5.1 years [SD = 1.7], 48.7% female). Among participants with completed evaluations, 81.8% had CIPN at T1 (74.5% motor, 34.1% sensory). When examining severity of PT/OT outcomes, only handgrip strength (P < .001) and walking efficiency (P = .02) improved from T1-T4, and only dorsiflexion range of motion (46.7% vs 14.7%; P = .008) and handgrip strength (22.2% vs 37.1%; P = .03) differed in vincristine and dexamethasone every 4 weeks vs vincristine and dexamethasone 12 weeks at T4. Proxy-reported outcomes improved from T1 to T4 (P < .001), and most did not differ between groups.Conclusions: CIPN is prevalent early in B-ALL therapy and persists at least 12 months posttherapy. Most outcomes did not differ between treatment groups despite reduction in vincristine frequency. Children with B-ALL should be monitored for CIPN, even with reduced vincristine frequency.

Background: Adult childhood cancer survivors are at risk for frailty, including low muscle mass and weakness (sarcopenia). Using peripheral blood mitochondrial DNA copy number (mtDNAcn) as a proxy for functional mitochondria, this study describes cross-sectional associations between mtDNAcn and sarcopenia among survivors.Methods: Among 1762 adult childhood cancer survivors (51.6% male; median age = 29.4 years, interquartile range [IQR] = 23.3-36.8), with a median of 20.6 years from diagnosis (IQR = 15.2-28.2), mtDNAcn estimates were derived from whole-genome sequencing. A subset was validated by quantitative polymerase chain reaction and evaluated cross-sectionally using multivariable logistic regression for their association with sarcopenia, defined by race-, age-, and sex-specific low lean muscle mass or weak grip strength. All statistical tests were 2-sided.Results: The prevalence of sarcopenia was 27.0%, higher among female than male survivors (31.5% vs 22.9%; P < .001) and associated with age at diagnosis; 51.7% of survivors with sarcopenia were diagnosed ages 4-13 years (P = .01). Sarcopenia was most prevalent (39.0%) among central nervous system tumor survivors. Cranial radiation (odds ratio [OR] = 1.84, 95% confidence interval [CI] = 1.32 to 2.59) and alkylating agents (OR = 1.34, 95% CI = 1.04 to 1.72) increased, whereas glucocorticoids decreased odds (OR = 0.72, 95% CI = 0.56 to 0.93) of sarcopenia. mtDNAcn decreased with age (β = -0.81, P = .002) and was higher among female survivors (β = 9.23, P = .01) and among survivors with a C allele at mt.204 (β = -17.9, P = .02). In adjusted models, every standard deviation decrease in mtDNAcn increased the odds of sarcopenia 20% (OR = 1.20, 95% CI = 1.07 to 1.34).Conclusions: A growing body of evidence supports peripheral blood mtDNAcn as a biomarker for adverse health outcomes; however, this study is the first to report an association between mtDNAcn and sarcopenia among childhood cancer survivors.

Background: Some adult survivors of childhood cancers develop frailty at higher rates than expected based on their chronological age. This study examined the incidence of frailty among survivors at 10 or more years after diagnosis, frailty prevalence 5 years later, and risk factors for becoming frail.Methods: Frailty was measured at study entry and 5 years later. Logistic regression tested the associations of several factors with having frailty at 5 years for all participants and separately by sex and by study entry frailty status. Cox models evaluated the hazard of death associated with entry frailty considering covariates.Results: Cancer survivors (range = 0-22 years at diagnosis, median = 7 years) were ages 18-45 years (median = 30 years) at study entry. Frailty prevalence increased from 6.2% (95% confidence interval [CI] = 5.0% to 7.5%) to 13.6% (95% CI = 11.9% to 15.4%) at 5 years. Risk factors for frailty at follow-up among all survivors included chest radiation 20 Gy or higher (odds ratio [OR] = 1.98, 95% CI = 1.29 to 3.05), cardiac (OR = 1.58, 95% CI = 1.02 to 2.46), and neurological (OR = 2.58, 95% CI = 1.69 to 3.92) conditions; lack of strength training (OR = 1.74, 95% CI = 1.14 to 2.66); sedentary lifestyle (OR = 1.75, 95% CI = 1.18 to 2.59); and frailty at study entry (OR = 11.12, 95% CI = 6.64 to 18.61). The strongest risk factor for death during follow-up was prior frailty (OR = 3.52, 95% CI = 1.95 to 6.32).Conclusions: Prevalent frailty more than doubled at 5 years after study entry among adult childhood cancer survivors. Frailty at entry was the strongest risk factor for death. Because treatment exposures cannot be changed, mitigation of other risk factors for frailty, including lack of strength training and sedentary lifestyle, may decrease risk of adverse health events and improve longevity in survivors.

Background: Mounting evidence supports the occurrence of accelerating aging among long-term survivors of childhood cancer. We aimed to investigate epigenetic age acceleration (EAA) in survivors and evaluate associations between EAA, treatment exposures, health behaviors, and chronic health conditions (CHCs).Methods: Genome-wide methylation data were generated with Infinium EPIC BeadChip on blood-derived DNA from 2139 survivors and 282 frequency matched controls from the St Jude Lifetime Cohort Study. EAAs were estimated as residuals from a linear regression of epigenetic age (Levine's clock) against chronological age. Adjusted least square mean (ALSM) of EAA was calculated and compared between survivors and controls, across treatment exposures and health behaviors. Associations of EAA with 20 clinically assessed CHCs were evaluated with multivariable piecewise-exponential models. All statistical tests for P values below were 2-sided.Results: EAA was statistically significantly higher in survivors than controls (ALSM = 0.63, 95% confidence interval [CI] = 0.26 to 1.01 vs -3.61, 95% CI = -4.43 to 2.80). In a multivariable model among survivors, statistically significantly higher EAA (P < .05) was observed in those exposed to chest radiotherapy, abdomen or pelvic radiotherapy, alkylating agents, glucocorticoids, or epipodophyllotoxins. Compared with survivors with favorable health behaviors (ALSM = 0.26, 95% CI=-0.36 to 0.87), EAA was statistically significantly higher among survivors with intermediate (ALSM = 1.07, 95% CI = 0.59 to 1.54) or unfavorable health behaviors (ALSM = 1.45, 95% CI = 0.60 to 2.30). In time-to-event analyses, statistically significant associations were identified between EAA tertiles and incidence of 7 CHCs: hypertension (3rd vs 1st tertile, relative rate [RR] = 1.83, 95% CI = 1.17 to 2.83), myocardial infarction (RR = 2.91, 95% CI = 1.27 to 7.21), obesity (RR = 1.39, 95% CI = 1.17 to 1.66), obstructive pulmonary deficit (RR = 1.86, 95% CI = 0.95 to 3.77), peripheral motor neuropathy (RR = 2.89, 95% CI = 1.24 to 6.97), peripheral sensory neuropathy (RR = 2.04, 95% CI = 0.99 to 4.26), and pulmonary diffusion deficits (RR = 2.75, 95% CI = 0.95 to 7.63).Conclusions: EAA is statistically significantly higher in survivors of childhood cancer than in noncancer controls and is associated with specific treatment exposures, unfavorable health behaviors, and presence of specific CHCs.

Childhood cancer survivors treated with radiation therapy (RT) and osteotoxic chemotherapies are at increased risk for fractures. However, understanding of how genetic and clinical susceptibility factors jointly contribute to fracture risk among survivors is limited. To address this gap, we conducted genome‐wide association studies of fracture risk after cancer diagnosis in 2453 participants of European ancestry from the Childhood Cancer Survivor Study (CCSS) with 930 incident fractures using Cox regression models (ie, time‐to‐event analysis) and prioritized sex‐ and treatment‐stratified genetic associations. We performed replication analyses in 1417 survivors of European ancestry with 652 incident fractures from the St. Jude Lifetime Cohort Study (SJLIFE). In discovery, we identified a genome‐wide significant (p < 5 × 10−8) fracture risk locus, 16p13.3 (HAGHL), among female CCSS survivors (n = 1289) with strong evidence of sex‐specific effects (psex‐heterogeneity < 7 × 10−6). Combining discovery and replication data, rs1406815 showed the strongest association (hazard ratio [HR] = 1.43, p = 8.2 × 10−9; n = 1935 women) at this locus. In treatment‐stratified analyses in the discovery cohort, the association between rs1406815 and fracture risk among female survivors with no RT exposures was weak (HR = 1.22, 95% confidence interval [CI] 0.95–1.57, p = 0.11) but increased substantially among those with greater head/neck RT doses (any RT: HR = 1.88, 95% CI 1.54–2.28, p = 2.4 × 10−10; >36 Gray only: HR = 3.79, 95% CI 1.95–7.34, p = 8.2 × 10−5). These head/neck RT‐specific HAGHL single‐nucleotide polymorphism (SNP) effects were replicated in female SJLIFE survivors. In silico bioinformatics analyses suggest these fracture risk alleles regulate HAGHL gene expression and related bone resorption pathways. Genetic risk profiles integrating this locus may help identify female survivors who would benefit from targeted interventions to reduce fracture risk. © 2020 American Society for Bone and Mineral Research (ASBMR).

11-17 Health outcomes research findings have had a major influence on changes in paediatric cancer therapy and have informed health-screening strategies of childhood cancer survivors. 7-10 Current understanding of late health outcomes in adult survivors of childhood cancer has largely been the result of a number of cohort studies that have been instrumental in identifying, quantifying and characterizing cancer treatment-related health risks. Robust characterization of health outcomes and cancer-, cancer treatmentand health behaviour-related exposures provide an unparalleled opportunity to identify novel associations and to refine our understanding of the effects of cancer and its treatment on the health of aging survivors. Whereas SJLIFE does not specify age at cancer diagnosis, SJCRH generally restricts acceptance to children<25 years of age at the time of cancer diagnosis. [Extracted from the article]

Background: We aimed to systematically evaluate telomere dynamics across a spectrum of pediatric cancers, search for underlying molecular mechanisms, and assess potential prognostic value.Methods: The fraction of telomeric reads was determined from whole-genome sequencing data for paired tumor and normal samples from 653 patients with 23 cancer types from the Pediatric Cancer Genome Project. Telomere dynamics were characterized as the ratio of telomere fractions between tumor and normal samples. Somatic mutations were gathered, RNA sequencing data for 330 patients were analyzed for gene expression, and Cox regression was used to assess the telomere dynamics on patient survival.Results: Telomere lengthening was observed in 28.7% of solid tumors, 10.5% of brain tumors, and 4.3% of hematological cancers. Among 81 samples with telomere lengthening, 26 had somatic mutations in alpha thalassemia/mental retardation syndrome X-linked gene, corroborated by a low level of the gene expression in the subset of tumors with RNA sequencing. Telomerase reverse transcriptase gene amplification and/or activation was observed in 10 tumors with telomere lengthening, including two leukemias of the E2A-PBX1 subtype. Among hematological cancers, pathway analysis for genes with expressions most negatively correlated with telomere fractions suggests the implication of a gene ontology process of antigen presentation by Major histocompatibility complex class II. A higher ratio of telomere fractions was statistically significantly associated with poorer survival for patients with brain tumors (hazard ratio = 2.18, 95% confidence interval = 1.37 to 3.46).Conclusion: Because telomerase inhibitors are currently being explored as potential agents to treat pediatric cancer, these data are valuable because they identify a subpopulation of patients with reactivation of telomerase who are most likely to benefit from this novel therapeutic option.

Background In noncancer populations, insomnia is known to affect neurocognitive processes. Although the prevalence of insomnia appears to be elevated in survivors of childhood cancer, relatively little is known about its association with neurocognitive performance in this at-risk population. Methods A total of 911 survivors (51.9% female; mean [SD] age, 34 [9.0] years; time since diagnosis, 26 [9.1] years) completed direct assessments of attention, memory, processing speed, and executive functioning and self-reported symptoms of sleep (Pittsburgh Sleep Quality Index), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue), and daytime sleepiness (Epworth Sleepiness Scale). Sex-stratified general linear models were used to examine associations between insomnia and neurocognitive performance, with adjustment for treatment exposures and chronic health conditions. All statistical tests were two-sided. Results Insomnia was reported by 22.1% of females and 12.3% of males (P  < .001). After adjustment for neurotoxic treatment exposures, insomnia (vs healthy sleepers with no daytime fatigue or sleepiness) was associated with worse neurocognitive performance in the domains of verbal reasoning, memory, attention, executive function, and processing speed (verbal reasoning: males β = −0.34, P  = .04, females β = −0.57, P  < .001; long-term memory: males β = −0.60, P  < .001, females β = −0.36, P  = .02; sustained attention: males β = −0.85, P  < .001, females β = −0.42, P  = .006; cognitive flexibility: males β = −0.70, P  =  .002, females β = −0.40, P  = .02). Self-reported sleep disturbance without daytime fatigue or sleepiness or daytime fatigue or sleepiness alone were not consistently associated with poorer neurocognitive performance. Conclusions Insomnia was highly prevalent and contributed to the neurocognitive burden experienced by adult survivors of childhood cancer. Treatment of insomnia may improve neurocognitive problems in survivors. [ABSTRACT FROM AUTHOR]

Background Glucocorticoids used to treat childhood leukemia and lymphoma can result in osteonecrosis, leading to physical dysfunction and pain. Improving survival rates warrants research into long-term outcomes among this population. Objective The objective of this study was to compare the physical function and quality of life (QOL) of survivors of childhood cancer who had an osteonecrosis history with that of survivors who had no osteonecrosis history and with that of people who were healthy (controls). Design This was a cross-sectional study. Methods This study included St Jude Lifetime Cohort Study participants who were ≥ 10 years from the diagnosis of childhood leukemia or lymphoma and ≥ 18 years old; 135 had osteonecrosis (52.5% men; mean age = 27.7 [SD = 6.08] years) and 1560 had no osteonecrosis history (52.4% men; mean age = 33.3 [SD = 8.54] years). This study also included 272 people who were from the community and who were healthy (community controls) (47.7% men; mean age = 35.1 [SD = 10.46] years). The participants completed functional assessments and questionnaires about QOL. Results Survivors with osteonecrosis scored lower than other survivors and controls for dorsiflexion strength (mean score = 16.50 [SD = 7.91] vs 24.17 [SD = 8.61] N·m/kg) and scored lower than controls for flexibility with the sit-and-reach test (20.61 [SD = 9.70] vs 23.96 [SD = 10.73] cm), function on the Physical Performance Test (mean score = 22.73 [SD = 2.05] vs 23.58 [SD = 0.88]), and mobility on the Timed "Up & Go" Test (5.66 [SD = 2.25] vs 5.12 [SD = 1.28] seconds). Survivors with hip osteonecrosis requiring surgery scored lower than survivors without osteonecrosis for dorsiflexion strength (13.75 [SD = 8.82] vs 18.48 [SD = 9.04] N·m/kg), flexibility (15.79 [SD = 8.93] vs 20.37 [SD = 10.14] cm), and endurance on the 6-minute walk test (523.50 [SD = 103.00] vs 572.10 [SD = 102.40] m). Limitations Because some eligible survivors declined to participate, possible selection bias was a limitation of this study. Conclusions Survivors of childhood leukemia and lymphoma with and without osteonecrosis demonstrated impaired physical performance and reported reduced QOL compared with controls, with those requiring surgery for osteonecrosis most at risk for impairments. It may be beneficial to provide strengthening, flexibility, and endurance interventions for patients who have pediatric cancer and osteonecrosis for long-term function. [ABSTRACT FROM AUTHOR]

Observational data have shown that some cancer survivors develop chronic conditions like frailty, sarcopenia, cardiac dysfunction, and mild cognitive impairment earlier and/or at a greater burden than similarly aged individuals never diagnosed with cancer or exposed to systemic or targeted cancer therapies. In aggregate, cancer- and treatment-related physical, cognitive, and psychosocial late- and long-term morbidities experienced by cancer survivors are hypothesized to represent accelerated or accentuated aging trajectories. However, conceptual, measurement, and methodological challenges have constrained efforts to identify, predict, and mitigate aging-related consequences of cancer and cancer treatment. In July 2018, the National Cancer Institute convened basic, clinical, and translational science experts for a think tank titled "Measuring Aging and Identifying Aging Phenotypes in Cancer Survivors." Through the resulting deliberations, several research and resource needs were identified, including longitudinal studies to examine aging trajectories that include detailed data from before, during, and after cancer treatment; mechanistic studies to elucidate the pathways that lead to the emergence of aging phenotypes in cancer survivors; long-term clinical surveillance to monitor survivors for late-emerging effects; and tools to integrate multiple data sources to inform understanding of how cancer and its therapies contribute to the aging process. Addressing these needs will help expand the evidence base and inform strategies to optimize healthy aging of cancer survivors. [ABSTRACT FROM AUTHOR]

Advances in early detection, treatment, and supportive care have resulted in an estimated 16 million cancer survivors who are alive in the United States today. Outcomes have notably improved for children with cancer as well as young adults with hematologic malignancies due, in part, to the intensification of cancer treatment, including the use of hematopoietic cell transplantation. Emerging evidence suggests that these cancer survivors are at risk for premature aging, manifesting as early onset of chronic health conditions and a higher risk of mortality compared with the general population. Although the pathophysiology of premature aging in these survivors has not been fully elucidated, emerging concepts in aging research could help shed light on this phenomenon. Longitudinal studies are needed to better characterize aging in these survivors, setting the stage for much-needed interventions to halt the trajectory of accelerated aging. These efforts will be enhanced through collaborations between translational researchers, clinical oncologists, primary care providers, geriatricians, patient caretakers, and other stakeholders committed to improving the lives of the growing population of survivors.

In May 2018, the National Cancer Policy Forum (NCPF) of the National Academies of Sciences, Engineering, and Medicine (formerly the Institute of Medicine) released a report, Long-Term Survivorship Care After Cancer Treatment: Proceedings of Workshop. NCPF-published reports have historically played a significant role in driving policy and payment model changes in oncology care, in addition to raising awareness about the needs of individuals with cancer. This 2018 report provides a specific set of recommendations for improving symptom management and rehabilitation that suggest the integration of rehabilitation services at the point of cancer diagnosis and throughout the continuum of cancer care to effectively screen for and manage the anticipated functional morbidity associated with cancer treatment. The specificity of these recommendations is of significant relevance to the physical therapy profession and should encourage bold steps to effectively increase the presence of physical therapists as members of interdisciplinary cancer care teams. The profession must act to implement models of prospective care, develop targeted education and training initiatives to assure the knowledge and skills of our workforce for this complex population, and augment the current evidence base with greater attention to health services research aiming to understand the effectiveness of rehabilitation services in improving costs, utilization, and meaningful functional outcomes.

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

Background. Survivors of childhood acute lymphoblastic leukemia (ALL) are at risk for low lean muscle mass and muscle weakness, which may contribute to inactivity and early development of chronic diseases typically seen in older adults. Although increasing protein intake, in combination with resistance training, improves lean muscle mass in other populations, it is not known whether muscular tissue among survivors of ALL, whose impairments are treatment-related, will respond similarly. Objective. The aim of this study was to evaluate associations among dietary protein intake, resistance training, and lean muscle mass in survivors of ALL and age-, sex-, and race-matched controls. Design. This was a cross-sectional study. Methods. Lean muscle mass was determined with dual-energy x-ray absorptiometry, dietary information with 24-hour recalls, and participation in resistance training with a questionnaire. Participants were 365 survivors of ALL (52% male; 87% white; median age=28.5 years, range=23.6-31.7) and 365 controls with no previous cancer. Results. Compared with controls, survivors of ALL had lower lean muscle mass (55.0 versus 57.2 kg, respectively) and lower percentage of lean muscle mass (68.6% versus 71.4%, respectively) than controls. Similar proportions of survivors (71.1%) and controls (69 7%) met recommended dietary protein intake (0.8 g/kg/d). Survivors (45.4%) were less likely to report resistance training than controls (53.8%). In adjusted models, 1-g higher protein intake per kilogram of body mass per day was associated with a 7.9% increase and resistance training ≥1xwk, with a 2.8% increase in lean muscle mass. Limitations. The cross-sectional study design limits temporal evaluation of the association between protein intake and lean muscle mass. Conclusions. The findings suggest that survivors of childhood ALL with low lean muscle mass may benefit from optimizing dietary protein intake in combination with resistance training. Research is needed to determine whether resistance training with protein supplementation improves lean muscle mass in survivors of childhood ALL. [ABSTRACT FROM AUTHOR]

RE: Progression of frailty in survivors of childhood cancer: a St. Jude Lifetime Cohort report. Given that we only had 77 deaths in the cohort, 22 related to a second malignant neoplasm and 20 to cardiac causes, our power to evaluate multiple risk factors for specific causes of death was limited. We thank Makiyama and colleagues for their careful review and critique of our manuscript, I Progression of Frailty in Survivors of Childhood Cancer: a St. Jude Lifetime Cohort Report i , and for the suggestion that we construct an additional model to assure that frailty is in fact a cause of mortality in childhood cancer survivors ([1]).

Adult survivors of childhood cancer are known to be at increased risk of subsequent malignancy, but only limited data exist describing the incidence and risk factors for secondary renal carcinoma. Among 14 358 5-year survivors diagnosed between 1970 and 1986, we estimated standardized incidence ratios (SIRs) for subsequent renal carcinoma and identified associations with primary cancer therapy using Poisson regression. Twenty-six survivors were diagnosed with renal carcinoma (median = 22.6 years from diagnosis; range = 6.3–35.7 years), reflecting a statistically significant excess (SIR = 8.0, 95% confidence interval [CI] = 5.2 to 11.7) compared with the general population. Highest risk was observed among neuroblastoma survivors (SIR = 85.8, 95% CI = 38.4 to 175.2) and, in multivariable analyses, with renal-directed radiotherapy of 5 Gy or greater (relative risk [RR] = 3.8, 95% CI = 1.6 to 9.3) and platinum-based chemotherapy (RR = 3.5, 95% CI = 1.0 to 11.2). To our knowledge, this is the first report of an association between cisplatin and subsequent renal carcinoma among survivors of childhood cancer. [ABSTRACT FROM AUTHOR]

Objective To report the prevalence and comparison of cancer-linked health behaviors and identify risk factors associated with unhealthy behavior among adolescent siblings and cancer survivors. Methods The Child Health and Illness Profile—Adolescent Edition (CHIP—AE) was completed by 307 survivors and 97 sibling controls 14–20 years of age. Results Risky behavior ranged from 0.7% to 35.8% for survivors and 1.0% to 41.2% for siblings. Comparisons of sexual behavior, tobacco, alcohol, or illicit drug use utilizing continuous data revealed no differences between groups. Categorically, survivors were less likely to report past smokeless tobacco use or current use of beer/wine or binge drinking (p-values range from .01 to .04). Survivors with better mental health were at lower risk for poor behavioral outcomes. Conclusions Adolescent survivors engage in risky health behaviors at rates generally equivalent to their siblings. Aggressive health education efforts should be directed toward this high-risk population. [ABSTRACT FROM AUTHOR]

Background The survival of Ewing sarcoma (ES) patients has improved since the 1970s but is associated with considerable future health risks. Methods The study population consisted of long-term (≥5-year) survivors of childhood ES diagnosed before age 21 from 1970 to 1986. Cause-specific mortality was evaluated in eligible survivors (n = 568), and subsequent malignant neoplasms, chronic health conditions, infertility, and health status were evaluated in the subset participating in the Childhood Cancer Survivor Study (n = 403). Outcomes were compared with the US population and sibling control subjects (n = 3899). Logistic, Poisson, or Cox proportional hazards models, with adjustments for sex, age, race/ethnicity, and potential intrafamily correlation, were used. Statistical tests were two-sided. Results Cumulative mortality of ES survivors was 25.0% (95% confidence interval [CI] = 21.1 to 28.9) 25 years after diagnosis. The all-cause standardized mortality ratio was 13.3 (95% CI = 11.2 to 15.8) overall, 23.1 (95% CI = 17.6 to 29.7) for women, and 10.0 (95% CI = 7.9 to 12.5) for men. The nonrecurrence-progression non-external cause standardized mortality ratio (subsequent non-ES malignant neoplasms and cardiac and pulmonary causes potentially attributable to ES treatment) was 8.7 (95% CI = 6.2 to 12.0). Twenty-five years after ES diagnosis, cumulative incidence of subsequent malignant neoplasms, excluding nonmelanoma skin cancers, was 9.0% (95% CI = 5.8 to 12.2). Compared with siblings, survivors had an increased risk of severe, life-threatening, or disabling chronic health conditions (relative risk = 6.0, 95% CI = 4.1 to 9.0). Survivors had lower fertility rates (women: P = .005; men: P < .001) and higher rates of moderate to extreme adverse health status (P < .001). Conclusion Long-term survivors of childhood ES exhibit excess mortality and morbidity. [ABSTRACT FROM AUTHOR]

Posterior fossa syndrome is characterized by cerebellar dysfunction, oromotor/oculomotor apraxia, emotional lability and mutism in patients after infratentorial injury. The underlying neuroanatomical substrates of posterior fossa syndrome are unknown, but dentatothalamocortical tracts have been implicated. We used pre- and postoperative neuroimaging to investigate proximal dentatothalamocortical tract involvement in childhood embryonal brain tumour patients who developed posterior fossa syndrome following tumour resection. Diagnostic imaging from a cohort of 26 paediatric patients previously operated on for an embryonal brain tumour (13 patients prospectively diagnosed with posterior fossa syndrome, and 13 non-affected patients) were evaluated. Preoperative magnetic resonance imaging was used to define relevant tumour features, including two potentially predictive measures. Postoperative magnetic resonance and diffusion tensor imaging were used to characterize operative injury and tract-based differences in anisotropy of water diffusion. In patients who developed posterior fossa syndrome, initial tumour resided higher in the 4th ventricle (P = 0.035). Postoperative magnetic resonance signal abnormalities within the superior cerebellar peduncles and midbrain were observed more often in patients with posterior fossa syndrome (P = 0.030 and 0.003, respectively). The fractional anisotropy of water was lower in the bilateral superior cerebellar peduncles, in the bilateral fornices, white matter region proximate to the right angular gyrus (Tailerach coordinates 35, –71, 19) and white matter region proximate to the left superior frontal gyrus (Tailerach coordinates –24, 57, 20). Our findings suggest that multiple bilateral injuries to the proximal dentatothalamocortical pathways may predispose the development of posterior fossa syndrome, that functional disruption of the white matter bundles containing efferent axons within the superior cerebellar peduncles is a critical underlying pathophysiological component of posterior fossa syndrome, and that decreased fractional anisotropy in the fornices and cerebral cortex may be related to the abnormal neurobehavioural symptoms of posterior fossa syndrome.

Adult survivors of childhood central nervous system (CNS) malignancies are at high risk for long-term morbidity and late mortality. However, patterns of late mortality, the long-term risks of subsequent neoplasms and debilitating medical conditions, and sociodemographic outcomes have not been comprehensively characterized for individual diagnostic and treatment groups. We collected information on treatment, mortality, chronic medical conditions, and neurocognitive functioning of adult 5-year survivors of CNS malignancies diagnosed between 1970 and 1986 within the Childhood Cancer Survivor Study. Using competing risk framework, we calculated cumulative mortality according to cause of death and cumulative incidence of subsequent neoplasms according to exposure and dose of cranial radiation therapy (RT). Neurocognitive impairment and socioeconomic outcomes were assessed with respect to dose of CNS radiotherapy to specific brain regions. Cumulative incidence of chronic medical conditions was compared between survivors and siblings using Cox regression models. All tests of statistical significance were two-sided. Among all eligible 5-year survivors (n = 2821), cumulative late mortality at 30 years was 25.8% (95% confidence interval [l] = 23.4% to 28.3%), due primarily to recurrence and/or progression of primary disease. Patients who received cranial RT of 50 Gy or more (n = 813) had a cumulative incidence of a subsequent neoplasm within the CNS of 7.1% (95% Cl = 4.5% to 9.6%) at 25 years from diagnosis compared with 1.0% (95% Cl = 0% to 2.3%) for patients who had no RT. Survivors had higher risk than siblings of developing new endocrine, neurological, or sensory complications 5 or more years after diagnosis. Neurocognitive impairment was high and proportional to radiation dose for specific tumor types. There was a dose-dependent association between RT to the frontal and/or temporal lobes and lower rates of employment, and marriage. Survivors of childhood CNS malignancies are at high risk for late mortality and for developing subsequent neoplasms and chronic medical conditions. Care providers should be informed of these risks so they can provide risk-directed care and develop screening guidelines. [ABSTRACT FROM AUTHOR]

The article examines the long-term and acute effects of cancer and its treatment. The use of the World Health Organization's "International Classification of Functioning, Disability and Health," (ICF) as a basis for the selection of outcome or assessment tools and screening or diagnostic tools among cancer patients is discussed. Physical therapy interventions for cancer patients may ameliorate or reverse impairments in body function and improve their ability to complete daily tasks.

Young adults were the only age group to defy the downward trend in cigarette use seen in the 1980s and 1990s. To help explain this phenomenon, we conducted an exploratory study to examine the association between the sociocultural contexts of young adults' everyday lives and their smoking attitudes and behaviors. “Context” was operationalized by (a) including students and nonstudents in the study population, and (b) selecting two distinctly different areas of Minnesota for examination. The study sites were Hibbing and environs (Range), the sparsely populated hub of the state's once-thriving iron ore industry, and the Twin Cities metropolitan area (Metro), center of state government, finance, transportation, education, and industry. This report focuses on the first phase of the study, which consisted of a computer-assisted telephone interview of 995 randomly selected young adults, aged 18–24. Approximately equal numbers of students and nonstudents were selected from each site. Exploratory factor analysis yielded four distinct scales related to alcohol consumption and partying (Drinking Behavior), the social attractiveness and utility of smoking (Social Utility), outdoor recreation (Outdoor Rec), and media use and hours of free time. We decided not to use the media and free time scale, however, because of its low Cronbach alpha (.42). We used polynomial logistic regression to evaluate the association between smoking status, gender, student status, location (Range vs. Metro), and the three retained scales. Results indicated that living on the Iron Range (OR = 2.6), being female (OR = 1.3), and scoring higher on the Social Utility scale (OR = 3.06) increased the risk of smoking, whereas being a student (OR = 0.53) decreased the risk substantially.

An introduction to the journal is presented that focuses on the involvement of rehabilitation practitioners with the population of patients who have oncologic diagnoses, including how physical function is most commonly measured across the oncology literature, measurement properties of instruments to document physical function, and studies that enumerate specific impairments or limitations in physical function in survivors of cancer.

Because of the high risk of falling and the recognition that falling is a "geriatric syndrome," screening for risk of falls has become popular al community health fairs. The purposes of this study were to determine whether health fair screening and educational intervention would result in behaviors that could reduce the risk of falls and to determine whether adoption of risk-reduction behaviors differed between people over age 65 years screened as being at high risk for falls arid those screened as being at lower risk for falls. Subjects and Methods. The Berg Balance Test was used to classify fall risk in 68 individuals aged 57 to 89 years who were attending a community health fair. A score of 45 or lower led to a categorization of the person being at high risk for falls. All subjects were provided recommendations intended to reduce fall risk. Participants were interviewed by telephone 30 days after the screening to assess implementation of these recommendations. Results. Seventy-two percent of the participants reported implementing al least one risk-reduction behavior. The high-risk group was more likely to implement risk reduction behaviors than the low-risk group. Discussion and Conclusion. Screening and education in a health fair setting appear to promote behaviors that could reduce fall risk among elderly people. Future study with a control group that does riot receive an educational intervention is needed to draw more definite conclusions about the value of this health promotion activity for fall prevention.

There is a growing population of childhood cancer survivors at risk for adverse outcomes, including sexual dysfunction. To estimate the prevalence of and risk factors for sexual dysfunction among adult female survivors of childhood cancer and evaluate associations between dysfunction and psychological symptoms/quality of life (QOL). Female survivors (N = 936, mean 7.8 ± 5.6 years at diagnosis; 31 ± 7.8 years at evaluation) and noncancer controls (N = 122) participating in the St. Jude Lifetime Cohort Study completed clinical evaluations, Sexual Functioning Questionnaires (SFQ), and Medical Outcomes Survey Short Forms 36 (SF-36). Linear models compared SFQ scores between sexually active survivors (N = 712) and controls; survivors with scores <10th percentile of controls were classified with sexual dysfunction. Logistic regression evaluated associations between survivor characteristics and sexual dysfunction, and between sexual dysfunction and QOL. Sexual dysfunction was defined by scores <10th percentile of noncancer controls on the SFQ overall, as well as the domains of arousal, interest, orgasm, and physical problems, while QOL was measured by scores on the SF-36 with both physical and mental summary scales. Sexual dysfunction was prevalent among 19.9% (95% CI 17.1, 23.1) of survivors. Those diagnosed with germ cell tumors (OR = 8.82, 95% CI 3.17, 24.50), renal tumors (OR = 4.49, 95% CI 1.89, 10.67), or leukemia (OR = 3.09, 95% CI 1.50, 6.38) were at greater risk compared to controls. Age at follow-up (45–54 vs 18–24 years; OR = 5.72, 95% CI 1.87, 17.49), pelvic surgery (OR = 2.03, 95% CI 1.18, 3.50), and depression (OR = 1.96, 95% CI 1.10, 3.51) were associated with sexual dysfunction. Hypogonadism receiving hormone replacement (vs nonmenopausal/nonhypogonadal; OR = 3.31, 95% CI 1.53, 7.15) represented an additional risk factor in the physical problems (eg, vaginal pain and dryness) subscale. Survivors with sexual dysfunction, compared to those without sexual dysfunction, were more likely to score <40 on the physical (21.1% vs 12.7%, P =.01) and mental health (36.5% vs 18.2%, P <.01) summary scales of the SF-36. Only 2.9% of survivors with sexual dysfunction reported receiving intervention. Health care providers should be aware of the increased risk of sexual dysfunction in this growing population, inquire about symptomology, and refer for appropriate intervention. Strengths of this study include the use of a validated tool for evaluating sexual function in a large population of clinically assessed female childhood cancer survivors. Limitations include potential for selection bias, and lack of clinically confirmed dysfunction. Sexual dysfunction is prevalent among female childhood cancer survivors and few survivors receive intervention; further research is needed to determine if those with sexual dysfunction would benefit from targeted interventions.
