Fine Motor Impairment and its Impact on Social Outcomes in Survivors of Pediatric Acute Lymphoblastic Leukemia: St Jude Lifetime Cohort Study.

OBJECTIVE: The impact of fine motor impairment among adult survivors of childhood acute lymphoblastic leukemia on life after treatment is unknown. METHODS: This study evaluated prevalence and utilized multivariate logistic regression to identify risk factors for fine motor impairment among survivors of acute lymphoblastic leukemia, and associations with educational attainment and social independence. Latent class analysis defined social independence (independent, moderately independent, dependent), using employment, independent living, personal care assistance, routine need assistance, driver's license status, and marital status inputs. RESULTS: Among 875 survivors who were ≥ 25 years old (age when most adults achieve independence) and ≥ 5 years from diagnosis (mean = 28.97 years), 33.6% had fine motor impairment, with scores at or below the 10th percentile of the scores of community controls (n = 460) on fine motor components of the Physical Performance Test and the Grooved Peg-Board Test. Survivors exposed to cranial radiation had more fine motor impairment than those without (45.8% vs 20.2%). Male sex (exposed: odds ratio [OR] = 2.55, 95.0% CI = 1.65-3.92; unexposed: OR = 3.02, 95.0% CI = 1.69-5.38), and lower scores on the Wechsler Abbreviated Scale of Intelligence (exposed: OR = 0.46, 95.0% CI = 0.36-0.58; unexposed: OR = 0.43, 95.0% CI = 0.31-0.58) were risk factors for neuropathy. A 1-point-higher total neuropathy score was associated with 8% (95.0% CI = 1%-17%) increased odds of fine motor impairment. Fine motor impairment was associated with less than a college education (less than high school: OR = 2.23, 95.0% CI = 1.20-4.14; high school diploma/general equivalency diploma: OR = 2.66, 95.0% CI = 1.65-4.30; vocational education: OR = 2.07, 95.0% CI = 1.38-3.13), and less social independence (moderately independent: OR = 1.80, 95.0% CI = 1.15-2.83; dependent: OR = 2.65, 95.0% CI = 1.25-5.64). CONCLUSION: Fine motor impairment in survivors of childhood acute lymphoblastic leukemia may interfere with optimal educational attainment and social independence. IMPACT: Early identification of survivors at risk for fine motor impairment, with timely intervention, may improve long-term outcomes.

Characterization of Patient Activation among Childhood Cancer Survivors in the St. Jude Lifetime Cohort Study (SJLIFE).

BACKGROUND: Patient activation describes a willingness to take action to manage health and is associated with health outcomes. The purpose of this study was to characterize patient activation and its association with psychological outcomes and health behaviors in childhood cancer survivors. METHODS: Participants were from the St. Jude Lifetime Cohort Study (SJLIFE). Activation levels (1-4, 4 = highest activation) were measured with the Patient Activation Measure (PAM). Psychological outcomes and health behaviors were obtained via self-report. Cognitive function was assessed by trained examiners. ANOVA or chi-squared tests were utilized to assess group-level differences in activation. Multivariable regression models were used to assess associations between PAM scores and outcomes of interest. RESULTS: Among 2708 survivors and 303 controls, more survivors endorsed lower activation levels than the controls (11.3 vs. 4.7% in level 1) and fewer survivors endorsed the highest level of activation than the controls (45.3 vs. 61.5% in level 4). Not endorsing depression (OR: 2.37, 95% CI 1.87-2.99), anxiety (OR: 2.21, 95% CI 1.73-2.83), and somatization symptoms (OR: 1.99, 95% CI 1.59-2.50), general fear (OR: 1.45, 95% CI 1.23-1.71) and body-focused (OR: 2.21, 95% CI 1.83-2.66), cancer-related worry, and physical (OR: 2.57, 95% CI 2.06-3.20) and mental (OR: 2.08, 95% CI 1.72-2.52) HRQOL was associated with higher levels of activation. Lower activation was associated with not meeting physical activity guidelines (OR: 2.07, 95% CI 1.53-2.80). CONCLUSIONS: Survivors endorsed lower activation levels than peers. Interventions to improve physical and psychological health outcomes could leverage these results to identify survivors who benefit from support in patient activation.

Neighborhood Vulnerability and Associations with Poor Health-Related Quality-of-Life Among Adult Survivors of Childhood Cancer.

BACKGROUND: Few studies investigate the relationship between neighborhood vulnerability and health-related quality-of-life (HRQOL) in the childhood cancer population. This study evaluated the impact of neighborhood vulnerability on HRQOL among adult survivors of childhood cancer. METHODS: This cross-sectional study included 4,393 adult survivors of childhood cancer from the St Jude Lifetime Cohort Study. At the baseline (2007-2020), HRQOL was assessed using the SF36v2's physical/mental components summaries (PCS/MCS). Neighborhood vulnerability was assessed using the overall, domain, and indicator-specific scores of the Social Vulnerability Index (SVI) and Minority Health SVI (MHSVI). Multivariable logistic regression was used to evaluate associations of neighborhood vulnerability (quartiles: Q1-Q4) with impaired HRQOL (1SD below the norm), adjusting for diagnosis, demographics, personal socioeconomic status (SES), lifestyle, and chronic health condition burden. Interactions of SVI/MHSVI with personal SES on impaired HRQOL were analyzed. RESULTS: Among survivors, 51.9% were male, averaging 30.3 years of age at evaluation and 21.5 years since diagnosis. Comparing neighborhoods with higher vs lower vulnerability (Q4 vs Q1), overall (OR = 1.60, 95%CI = 1.19-2.16) and domain-specific vulnerability (socioeconomic: OR = 1.59, 95%CI = 1.18-2.15; household composition: OR = 1.54, 95%CI = 1.16-2.06; housing/transportation: OR = 1.33, 95%CI = 1.00-1.76; medical vulnerability: OR = 1.60, 95%CI = 1.22-2.09) were significantly associated with impaired PCS, but not MCS. Residing in neighborhoods lacking urgent care clinics was significantly associated with impaired PCS (OR = 1.39, 95%CI = 1.08-1.78). Having lower vs higher personal education and living in higher vulnerability neighborhoods were associated with more impaired PCS (P  interaction=0.021). CONCLUSIONS: Specific aspects of neighborhood vulnerability increase the risk for impaired physical HRQOL. Addressing these neighborhood factors is essential to enhance the HRQOL of survivors.

Patient, Parent, and Oncologist Perspectives and Recommendations on the Right Way to Talk About Prognosis in Advanced Childhood Cancer.

PURPOSE: Clear prognostic communication is associated with improvements in quality of life and suffering for children with advanced illness. Yet recent evidence demonstrates that pediatric oncologists often avoid, defer, or soften prognostic disclosure. We aimed to describe pediatric cancer shareholder perspectives on quality prognostic communication to inform design of an intervention to improve prognostic disclosure in advanced childhood cancer. METHODS: Semi-structured interviews were conducted with a purposeful sample of pediatric patients with cancer (n = 20), parents (n = 20), and oncologists (n = 20) representing six institutions across five states. Rapid analysis was performed using the National Cancer Institute core communication functions to organize domains of inquiry. RESULTS: Three main themes were endorsed by participants regarding the ideal timing of prognostic disclosure: early, ongoing, individualized. Although each group emphasized the need for an individualized approach, oncologists rarely elicited patient/parent preferences for prognostic communication and more commonly inferred what a patient/family wanted to hear. Participants described five key pillars for how to facilitate quality prognostic disclosure: conversation leadership, overall attendance, patient inclusion, location, and atmosphere. They also identified four themes around ideal prognostic content: range of information, use of numbers, population-level versus patient-specific information, and tone/delivery. Discordant recommendations between patients/parents and oncologists emerged for how much and what information to share. CONCLUSION: Pediatric cancer shareholders advocated for diverse, and sometimes conflicting, approaches for prognostic disclosure. Although nearly all participants endorsed the importance of individualized prognostic disclosure, specific strategies to encourage or facilitate person-centered prognostic conversation are lacking. Future research will focus on collaboration with pediatric patients, parents, and oncologists to codesign a clinical intervention to improve prognostic communication for children with advanced cancer and their families.

Associations between perceived cancer impact and measures of health behavior in survivors of childhood cancer.

PURPOSE: Perceived cancer impact (PCI) is the degree to which one feels cancer has impacted one's life. It is unknown if PCI is associated with health behaviors. The aim of this study is to determine associations between PCI and health behaviors in childhood cancer survivors. METHODS: Participants were ≥ 5-year survivors enrolled in the St. Jude Lifetime (SJLIFE) cohort. The Brief Cancer Impact (BCIA) assessed PCI across four domains (caregiving/finances, diet/exercise, social/emotional functioning, religiosity). Responses were categorized as negative, neutral, or positive impact. Smoking, risky drinking, illicit drug use, and diet quality data were obtained via self-report. Physical activity (PA) was assessed via self-report and actigraphy. Cross-sectional and longitudinal associations between PCI and health behaviors were evaluated via multivariable logistic regression. RESULTS: A total of 3623 participants (mean age 30.4 ± 8.3 years, 49.6% female, 81.5% NH White) were included in baseline cross-sectional analysis; 1709 had a second visit 5.0 ± 1.4 years later and were included in longitudinal analysis. At baseline, the percentage of participants who endorsed cancer as having a negative impact on caregiving/finances was 37.5%, diet/exercise 30.5%, social/emotional functioning 40.6%, and religiosity 8.7%. Negative and neutral PCI across all four domains were cross-sectionally associated with all behaviors except illicit drug use. Negative and neutral PCI at the first time point across all four domains were associated with smoking, diet quality, and PA (ORs ranging from 1.35 to 2.41) in longitudinal analyses. CONCLUSIONS: Endorsing negative or neutral PCI is associated with adverse health behaviors. IMPLICATIONS FOR CANCER SURVIVORS: Promoting optimal health behavior should include addressing PCI.

Characterization of chronic pain, pain interference, and daily pain experiences in adult survivors of childhood cancer: a report from the Childhood Cancer Survivor Study.

ABSTRACT: Although survivors of childhood cancer are at an increased risk, little is known about the prevalence of chronic pain, associated interference, and daily pain experiences. Survivors (N = 233; mean age = 40.8 years, range 22-64 years; mean time since diagnosis = 32.7 years) from the Childhood Cancer Survivor Study completed pain and psychosocial measures. Survivors with chronic pain completed 2-week, daily measures assessing pain and psychological symptoms using mHealth-based ecological momentary assessment. Multivariable-modified Poisson and linear regression models estimated prevalence ratio estimates (PR) and mean effects with 95% confidence intervals (CI) for associations of key risk factors with chronic pain and pain interference, respectively. Multilevel mixed models examined outcomes of daily pain and pain interference with prior day symptoms. Ninety-six survivors (41%) reported chronic pain, of whom 23 (24%) had severe interference. Chronic pain was associated with previous intravenous methotrexate treatment (PR = 1.6, 95% CI 1.1-2.3), respiratory (PR = 1.8, 95% CI 1.2-2.5), gastrointestinal (PR = 1.6, 95% CI 11.0-2.3), and neurological (PR = 1.5, 95% CI 1.0-2.1) chronic health conditions, unemployment (PR = 1.4, 95% CI 1.0-1.9) and clinically significant depression and anxiety (PR = 2.9, 95% CI 2.0-4.2), as well as a diagnosis of childhood Ewing sarcoma or osteosarcoma (PR = 1.9, 95% CI 1.0-3.5). Higher pain interference was associated with cardiovascular and neurological conditions, unemployment and clinical levels of depression and/or anxiety, and fear of cancer recurrence. For male, but not female survivors, low sleep quality, elevated anxiety, and elevated depression predicted high pain intensity and interference the next day. A substantial proportion of childhood cancer survivors experience chronic pain and significant associated interference. Chronic pain should be routinely evaluated, and interventions are needed.

Motor and sensory impairment in survivors of childhood central nervous system (CNS) tumors in the St. Jude Lifetime Cohort (SJLIFE).

BACKGROUND: Survivors of childhood central nervous system (CNS) tumors can develop motor and sensory impairment from their cancer and treatment history. We estimated the prevalence of motor and sensory impairment in survivors compared with controls through clinical assessment and identified associated treatment exposures and functional, quality of life (QOL), and social outcomes. METHODS: Survivors of childhood CNS tumors from the St. Jude Lifetime Cohort (n = 378, median [range] age 24.0 [18.0-53.0] years, 43.4% female) ≥5 years from diagnosis and controls (n = 445, median [range] age 34.0 [18.0-70.0] years, 55.7% female) completed in-person evaluation for motor and sensory impairment using the modified Total Neuropathy Score. Impairment was graded by modified Common Terminology Criteria for Adverse Events. Multivariable models estimated associations between grade ≥2 motor/sensory impairment, individual/treatment characteristics, and secondary outcomes (function by Physical Performance Test, fitness by physiologic cost index, QOL by Medical Outcomes Survey Short Form-36 physical/mental summary scores, social attainment). RESULTS: Grade ≥2 motor or sensory impairment was more prevalent in survivors (24.1%, 95% Confidence Interval [CI] 19.8%-29.4%) than controls (2.9%, CI 1.4-4.5%). Among survivors, in multivariable models, motor impairment was associated with vinca exposure <15 mg/m2 versus none (OR 4.38, CI 1.06-18.08) and etoposide exposure >2036 mg/m2 versus none (OR 12.61, CI 2.19-72.72). Sensory impairment was associated with older age at diagnosis (OR 1.09, CI 1.01-1.16) and craniospinal irradiation versus none (OR 4.39, CI 1.68-11.50). There were lower odds of motor/sensory impairment in survivors treated in the year 2000 or later versus before 1990 (Motor: OR 0.29, CI 0.10-0.84, Sensory: OR 0.35, CI 0.13-0.96). Motor impairment was associated with impaired physical QOL (OR 2.64, CI 1.22-5.72). CONCLUSIONS: In survivors of childhood CNS tumors, motor and sensory impairment is prevalent by clinical assessment, especially after exposure to etoposide, vinca, or craniospinal radiation. Treating motor impairment may improve survivors' QOL.

Neurocognitive outcomes and functional independence in adult survivors of childhood medulloblastoma diagnosed over three decades.

BACKGROUND: Treatment of childhood medulloblastoma has evolved to reduce neurotoxicity while improving survival. However, the impact of evolving therapies on late neurocognitive outcomes and adult functional independence remains unknown. METHODS: Adult survivors of childhood medulloblastoma (n=505; median[minimum-maximum] age, 29[18-46] years) and sibling controls (n=727; 32[18-58] years) from the Childhood Cancer Survivor Study completed surveys assessing neurocognitive problems and chronic health conditions (CHCs). Treatment exposures were categorized as historical (craniospinal irradiation [CSI]≥30 Gy, no chemotherapy), standard-risk (CSI>0 to <30 Gy +chemotherapy) and high-risk (CSI≥30 Gy +chemotherapy) therapy. Latent class analysis identified patterns of functional independence using employment, independent living, assistance with routine/personal care needs, driver's license, marital/partner status. Multivariable models estimated risk of neurocognitive impairment in survivors versus siblings and by treatment exposure group, and associations between neurocognitive impairment, CHCs, and functional independence. RESULTS: Survivors in each treatment exposure group had 4- to 5-fold elevated risk of impaired memory and task efficiency compared to siblings. Contemporary risk-based therapies did not confer lower risk compared to historical therapy. Survivors treated in the 1990s had higher risk of memory impairment (relative risk [RR] 2.24, 95% confidence interval [CI] 1.39-3.60) compared to survivors treated in the 1970s. Sensorimotor, hearing problems and seizures were associated with 33%-34%, 25-26% and 21%-42% elevated risk of task efficiency and memory impairment, respectively. Treatment-related CHCs and neurocognitive impairment were associated with non-independence. CONCLUSIONS: Despite treatment changes, long-term survivors of childhood medulloblastoma remain at risk for neurocognitive impairment, which was associated with CHCs. Neurocognitive surveillance after contemporary regimens is imperative.

Using Neurocognitive Phenotypes to Inform Interventions for Adult Survivors of Childhood Cancer.

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 2,958 (74.1%) eligible survivors, who were ≥5 years post-diagnosis and >18 years old, 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/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 [95%CI] 11.41-35.63) including cerebrovascular disease (OR = 14.5, 95%CI = 5.47-38.44) and cerebrovascular accident (OR = 14.7, 95%CI = 7.50-26.40). Modifiable risk factors, like quitting smoking reduced risk for global impairment (OR = 0.21, 95%CI 0.06-0.66). Low physical activity increased risk for global impairment (OR = 4.54, 95%CI 2.86-7.21), attention impairment (OR 2.01, 95%CI 1.41-2.87), processing speed/executive function impairment (OR 1.90, 95%CI 1.46-2.48), and memory impairment (OR 2.09, 95%CI 1.54-2.82). 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.

Cerebellar Mutism Syndrome and Dentato-Thalamo-Cortical Tract Disruption in Diffusion Tractography Following Surgery for Medulloblastoma.

Background Cerebellar mutism syndrome (CMS), a complication following medulloblastoma surgery, has been linked to dentato-thalamo-cortical tract (DTCT) injury; the association of the degree of DTCT injury with severity of CMS-related symptoms has not been investigated. Purpose To investigate the association between severity of CMS-related symptoms and degree and patterns of DTCT injury with use of diffusion tensor imaging (DTI), and if laterality of injury influences neurologic symptoms. Materials and Methods This retrospective case-control study used prospectively collected clinical and DTI data on patients with medulloblastoma enrolled in a clinical trial (between July 2016 and February 2020) and healthy controls (between April and November 2017), matched with the age range of the participants with medulloblastoma. CMS was divided into types 1 (CMS1) and 2 (CMS2). Multivariable logistic regression was used to investigate the relationship between CMS likelihood and DTCT injury. Results Overall, 82 participants with medulloblastoma (mean age, 11.0 years ± 5.2 [SD]; 53 male) and 35 healthy controls (mean age, 18.0 years ± 3.06; 18 female) were included. In participants with medulloblastoma, DTCT was absent bilaterally (AB), absent on the right side (AR), absent on the left side (AL), or present bilaterally (PB), while it was PB in all healthy controls. Odds of having CMS were associated with higher degree of DTCT damage (AB, odds ratio = 272.7 [95% CI: 269.68, 275.75; P < .001]; AR, odds ratio = 14.40 [95% CI: 2.84, 101.48; P < .001]; and AL, odds ratio = 8.55 [95% CI: 1.15, 74.14; P < .001). Left (coefficient = -0.07, χ2 = 12.4, P < .001) and right (coefficient = -0.15, χ2 = 33.82, P < .001) DTCT volumes were negatively associated with the odds of CMS. More participants with medulloblastoma with AB showed CMS1; unilateral DTCT absence prevailed in CMS2. Lower DTCT volumes correlated with more severe ataxia. Unilateral DTCT injury caused ipsilateral dysmetria; AB caused symmetric dysmetria. PB indicated better neurologic outcome. Conclusion The severity of CMS-associated mutism, ataxia, and dysmetria was associated with DTCT damage severity. DTCT damage patterns differed between CMS1 and CMS2. © RSNA, 2024 Supplemental material is available for this article. See also the editorial by Dorigatti Soldatelli and Ertl-Wagner in this issue.

Adverse Childhood Experiences, Resilience, and Cardiovascular Disease in Adult Survivors of Childhood Cancer: A Report from the Childhood Cancer Survivor Study.

BACKGROUND: The impact of adverse childhood experiences (ACE, e.g., abuse, neglect, and/or household dysfunction experienced before the age of 18) and resilience on risk for cardiovascular disease (CVD) has not previously been investigated in adult survivors of childhood cancer. METHODS: We conducted a nested case-control study among long-term, adult-aged survivors of childhood cancer from the Childhood Cancer Survivor Study. Self-report questionnaires ascertained ACEs and resilience, and scores were compared between cases with serious/life-threatening CVD and controls without CVD matched on demographic and cardiotoxic treatment factors. RESULTS: Among 95 cases and 261 controls, the mean ACE score was 1.4 for both groups; 53.4% of survivors endorsed ≥1 ACE. No association was observed between ACEs or resilience and CVD in adjusted models. CONCLUSIONS: ACEs and resilience do not appear to contribute to CVD risk for adult survivors of childhood cancer with cardiotoxic treatment exposures. IMPACT: Although not associated with CVD in this population, ACEs are associated with serious health issues in other populations. Therefore, future studies could investigate the effects of ACEs on other health outcomes affecting childhood cancer survivors.

Hypogonadism and neurocognitive outcomes among childhood cancer survivors.

OBJECTIVE: Childhood cancer survivors are at risk for hypogonadism. The impact of hypogonadism on neurocognitive impairment and emotional distress in the non-cancer population has been shown; however, the relationship among the childhood cancer survivor population is unknown. We aimed to evaluate the contribution of hypogonadism to neurocognitive impairment and emotional distress among survivors. DESIGN: Cross-sectional study using retrospective cohort. METHODS: In total, 3628 survivors who completed standard neurocognitive tests (six domains: processing speed, memory, executive function, attention, academics, and global cognition) and self-reported emotional distress were included in our study. Participants were stratified by sex and gonadal status. Outcomes were compared between hypogonadal and eugonadal groups by multivariable analysis, adjusting for established predictors, and mediation analyses to determine the direct/indirect effects of hypogonadism on outcomes. RESULTS: The hypogonadal group exhibited a higher prevalence of neurocognitive impairment across domains, but no difference in emotional distress. Hypogonadal females exhibited higher relative risk (1.7, 95% CI, 1.2-2.5) for impaired visual processing speed, compared to eugonadal females after adjusting for cancer-related variables. In mediation models, hypogonadism had a significant direct (P < .01) and indirect (from P < .01) impact on impairment in visual processing speed among females. Males demonstrated direct (P = .03) and indirect (P = .04) impact of hypogonadism on motor processing speed. CONCLUSION: Processing speed may be the most vulnerable neurocognitive domain associated with hypogonadism in survivors, while other domains were mainly impacted by cancer-related variables. Our findings support the need for further evaluation of the impact of sex hormone replacement therapy on neurocognitive function.

Health-related quality of life and DNA methylation-based aging biomarkers among survivors of childhood cancer.

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: ß = -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: ß = -0.08 years, 95% CI = -0.124 to -0.037 years; P = .003; and 3 individual HRQOL domains) and ageadj_DNAmADM (physical component summaries: ß = -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.

Severe Sepsis During Treatment for Childhood Leukemia and Sequelae Among Adult Survivors.

Importance: Children undergoing treatment for leukemia are at increased risk of severe sepsis, a dysregulated immune response to infection leading to acute organ dysfunction. As cancer survivors, they face a high burden of long-term adverse effects. The association between sepsis during anticancer therapy and long-term organ dysfunction in adult survivors of childhood cancer has not been examined. Objective: To determine whether severe sepsis during therapy for leukemia in childhood is associated with subsequent chronic health conditions in adult survivors. Design, Setting, and Participants: This cohort study included 644 adult survivors of childhood leukemia who were diagnosed between January 1, 1985, and July 19, 2010, and participated in the St Jude Lifetime Cohort Study. Participants were excluded if they received hematopoietic cell transplant or had relapsed leukemia. Data collection ended June 30, 2017. Data were analyzed from July 1, 2020, to January 5, 2024. Exposures: Severe sepsis episodes, defined according to consensus criteria as septic shock, acute respiratory distress syndrome, or multiorgan dysfunction associated with infection occurring during anticancer therapy, were abstracted by medical record review for all participants. Main Outcomes and Measures: Common Terminology Criteria for Adverse Events-defined chronic health condition outcomes were independently abstracted. Associations between sepsis and cumulative incidence of chronic health conditions (eg, cardiovascular, pulmonary, kidney, neurological, and neurocognitive outcomes) were compared by adjusted hazard ratios from Cox proportional hazards logistic regression. Inverse propensity score weighting was used to adjust for potential confounders, including age, year of diagnosis, and leukemia type. Results: The study sample consisted of 644 adult survivors of pediatric leukemia (329 women [51.1%] and 315 men [48.9%]; including 56 with a history of acute myeloid leukemia and 585 with a history of acute lymphoblastic leukemia) who were most recently evaluated at a median age of 24.7 (IQR, 21.2-28.3) years at a median time after leukemia diagnosis of 17.3 (IQR, 13.7-21.9) years. Severe sepsis during treatment of acute childhood leukemia occurred in 46 participants (7.1%). Participants who experienced severe sepsis during treatment were more likely to develop moderate to severe neurocognitive impairment (29 of 46 [63.0%] vs 310 of 598 [51.8%]; adjusted hazard ratio, 1.86 [95% CI, 1.61-2.16]; P < .001) significantly affecting attention, executive function, memory and visuospatial domains. Sepsis was not associated with long-term risk of cardiovascular, pulmonary, kidney, or neurological chronic health conditions. Conclusions and Relevance: In this cohort study of long-term outcomes in survivors of pediatric leukemia, severe sepsis during anticancer therapy for leukemia was associated with a selectively increased risk for development of serious neurocognitive sequelae. Efforts to reduce the effects of anticancer therapy on long-term function and quality of life in survivors might include prevention of severe sepsis during therapy and early detection or amelioration of neurocognitive deficits in survivors of sepsis.

Temporal changes in treatment and late mortality and morbidity in adult survivors of childhood glioma: a report from the Childhood Cancer Survivor Study.

Pediatric glioma therapy has evolved to delay or eliminate radiation for low-grade tumors. This study examined these temporal changes in therapy with long-term outcomes in adult survivors of childhood glioma. Among 2,501 5-year survivors of glioma in the Childhood Cancer Survivor Study diagnosed 1970-1999, exposure to radiation decreased over time. Survivors from more recent eras were at lower risk of late mortality (≥5 years from diagnosis), severe/disabling/life-threatening chronic health conditions (CHCs) and subsequent neoplasms (SNs). Adjusting for treatment exposure (surgery only, chemotherapy, or any cranial radiation) attenuated this risk (for example, CHCs (1990s versus 1970s), relative risk (95% confidence interval), 0.63 (0.49-0.80) without adjustment versus 0.93 (0.72-1.20) with adjustment). Compared to surgery alone, radiation was associated with greater than four times the risk of late mortality, CHCs and SNs. Evolving therapy, particularly avoidance of cranial radiation, has improved late outcomes for childhood glioma survivors without increased risk for late recurrence.

Mechanisms of sleep disturbances in long-term cancer survivors: a childhood cancer survivor study report.

BACKGROUND: Sleep problems following childhood cancer treatment may persist into adulthood, exacerbating cancer-related late effects and putting survivors at risk for poor physical and psychosocial functioning. This study examines sleep in long-term survivors and their siblings to identify risk factors and disease correlates. METHODS: Childhood cancer survivors (≥5 years from diagnosis; n = 12 340; 51.5% female; mean [SD] age = 39.4 [9.6] years) and siblings (n = 2395; 57.1% female; age = 44.6 [10.5] years) participating in the Childhood Cancer Survivor Study completed the Pittsburgh Sleep Quality Index (PSQI). Multivariable Poisson-error generalized estimating equation compared prevalence of binary sleep outcomes between survivors and siblings and evaluated cancer history and chronic health conditions (CHC) for associations with sleep outcomes, adjusting for age (at diagnosis and current), sex, race/ethnicity, and body mass index. RESULTS: Survivors were more likely to report clinically elevated composite PSQI scores (>5; 45.1% vs 40.0%, adjusted prevalence ratio [PR] = 1.20, 95% CI = 1.13 to 1.27), symptoms of insomnia (38.8% vs 32.0%, PR = 1.26, 95% CI = 1.18 to 1.35), snoring (18.0% vs 17.4%, PR = 1.11, 95% CI = 1.01 to 1.23), and sleep medication use (13.2% vs 11.5%, PR = 1.28, 95% CI = 1.12 to 1.45) compared with siblings. Within cancer survivors, PSQI scores were similar across diagnoses. Anthracycline exposure (PR = 1.13, 95% CI = 1.03 to 1.25), abdominal radiation (PR = 1.16, 95% CI = 1.04 to 1.29), and increasing CHC burden were associated with elevated PSQI scores (PRs = 1.21-1.48). CONCLUSIONS: Among survivors, sleep problems were more closely related to CHC than diagnosis or treatment history, although longitudinal research is needed to determine the direction of this association. Frequent sleep-promoting medication use suggests interest in managing sleep problems; behavioral sleep intervention is advised for long-term management.

Association of hearing loss with patient-reported functional outcomes in adult survivors of childhood cancer.

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.

Psychological Outcomes in Adolescent and Young Adult Cancer Survivors.

The diagnosis of cancer during adolescent and young adulthood (AYA) may alter the development and psychological trajectory of survivors across their lifespan. The current review focuses broadly on emotional health, social functioning, health behaviors, and cancer-related cognitive impairment (CRCI) among AYA survivors. Overall, AYA survivors appear to be at elevated risk of emotional distress symptoms, mood and anxiety disorders, suicide, and mental health care service utilization compared with individuals without a cancer history. Difficulties with social relationships and reduced achievement of expected social outcomes including educational attainment and employment have been reported. Despite risk for health-related morbidities, including subsequent neoplasms, many AYA survivors do not engage in health behaviors at the recommended levels for physical activity, diet, or tobacco and alcohol use. Although CRCI has not been comprehensively characterized in this population, subgroups of AYA survivors appear to be at risk for experiencing CRCI, including survivors of central nervous system tumors, Hodgkin lymphoma, testicular, and breast cancer. Across each considered domain of psychological functioning, intervention efforts have largely focused on acceptability and feasibility with an increasing focus on e/mHealth approaches. Future research should include multiphase studies, including randomized controlled trials designed to evaluate intervention efficacy and effectiveness. It is imperative that psychological interventions consider the unique needs of AYA survivors by developmental stage and across multiple levels of influence (patient, support system, institution, and health care system).

Evolving therapies, neurocognitive outcomes, and functional independence in adult survivors of childhood glioma.

BACKGROUND: Treatment of childhood glioma has evolved to reduce radiotherapy exposure with the goal of limiting late toxicity. However, the associations between treatment changes and neurocognition, and the contribution of neurocognition and chronic health conditions to attainment of adult independence, remain unknown. METHODS: Adult survivors of childhood glioma diagnosed in 1970-1999 in the Childhood Cancer Survivor Study (n = 1284; median [minimum-maximum] 30 [18-51] years of age at assessment; 22 [15-34] years from diagnosis) self-reported neurocognitive impairment and chronic health conditions. Multivariable models evaluated associations between changes in treatment exposures (surgery only, chemotherapy [with or without surgery], cranial radiation [with or without chemotherapy and/or surgery]), and neurocognitive impairment. Latent class analysis with 5 indicators (employment, independent living, assistance with routine and/or personal care needs, driver's license, marital or partner status) identified classes of functional independence. Path analysis tested associations among treatment exposures, neurocognitive impairment, chronic health conditions, and functional independence. Statistical tests were 2-sided. RESULTS: Cranial radiation exposure decreased over time (51%, 1970s; 46%, 1980s; 27%, 1990s]. However, compared with siblings, survivors with any treatment exposure were at elevated risk for neurocognitive impairment, including surgery only (eg, memory: relative risk = 2.22; task efficiency: relative risk = 1.88; both P < .001). Three classes of functional independence were identified: independent (58%), moderately independent (20%), and nonindependent (22%). Cranial radiation was associated with nonindependence through impaired task efficiency (ß = 0.06), sensorimotor (ß = 0.06), and endocrine (ß = 0.10) chronic health conditions and through the associations between these conditions and task efficiency (each ß = 0.04). Sensorimotor and endocrine chronic health conditions were associated with nonindependence through memory. CONCLUSION: Most long-term glioma survivors achieve adult independence. However, functional nonindependence is associated with treatment-related neurocognitive impairment and chronic health conditions.

Neurologic morbidity and functional independence in adult survivors of childhood cancer.

OBJECTIVE: To examine associations between neurologic late effects and attainment of independence in adult survivors of childhood cancer treated with central nervous system (CNS)-directed therapies. METHODS: A total of 7881 survivors treated with cranial radiation therapy (n = 4051; CRT) and/or intrathecal methotrexate (n = 4193; IT MTX) ([CNS-treated]; median age [range] = 25.5 years [18-48]; time since diagnosis = 17.7 years [6.8-30.2]) and 8039 without CNS-directed therapy reported neurologic conditions including stroke, seizure, neurosensory deficits, focal neurologic dysfunction, and migraines/severe headaches. Functional independence was assessed using latent class analysis with multiple indicators (independent living, assistance with routine and personal care needs, ability to work/attend school, attainment of driver's license, marital/partner status). Multivariable regression models, adjusted for age, sex, race/ethnicity, and chronic health conditions, estimated odds ratios (OR) or relative risks (RR) for associations between neurologic morbidity, functional independence, and emotional distress. RESULTS: Among CNS-treated survivors, three classes of independence were identified: (1) moderately independent, never married, and non-independent living (78.7%); (2) moderately independent, unable to drive (15.6%); and (3) non-independent (5.7%). In contrast to 50% of non-CNS-treated survivors and 60% of siblings, a fourth fully independent class of CNS-treated survivors was not identified. History of stroke (OR = 2.50, 95% CI: 1.70-3.68), seizure (OR = 9.70, 95% CI: 7.37-12.8), neurosensory deficits (OR = 2.67, 95% CI: 2.16-3.31), and focal neurologic dysfunction (OR = 3.05, 95% CI: 2.40-3.88) were associated with non-independence among CNS-treated survivors. Non-independence was associated with emotional distress symptoms. INTERPRETATION: CNS-treated survivors do not attain full independence comparable to non-CNS-treated survivors or siblings. Interventions to promote independence may be beneficial for survivors with treatment-related neurological sequalae.
