With the widespread adoption of multimodality treatment, 5-year survival of children diagnosed with cancer has improved dramatically in the past several decades from approximately 60% in 1970 to greater than 85% currently. As a result, there are an estimated nearly half a million long-term survivors of childhood cancer living in the United States today. However, survivors have, on average, significantly greater serious medical and psychosocial late effects compared with the general population. In this review, we will discuss the current epidemiology of childhood cancer survivorship, including new methods to estimate the burden of late effects and genetic susceptibility toward late effects. We will also review the development of surveillance guidelines for childhood cancer survivors and early toxicity signals from novel agents now being tested and used increasingly to treat pediatric and adult cancers. We conclude with an overview of current models of survivorship care and areas for future research., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Inc.

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. [ABSTRACT FROM AUTHOR]

Social epigenomics is an emerging field in which social scientist collaborate with computational biologists, especially epigeneticists, to address the underlying pathway for biological embedding of life experiences. This social epigenomics study included long-term childhood cancer survivors enrolled in the St. Jude Lifetime Cohort. DNA methylation (DNAm) data were generated using the Illumina EPIC BeadChip, and three social determinants of health (SDOH) factors were assessed: self-reported educational attainment, personal income, and an area deprivation index based on census track data. An epigenome-wide association study (EWAS) was performed to evaluate the relation between DNAm at each 5'-cytosine-phosphate-guanine-3' (CpG) site and each SDOH factor based on multivariable linear regression models stratified by ancestry (European ancestry, n = 1,618; African ancestry, n = 258). EWAS among survivors of European ancestry identified 130 epigenome-wide significant SDOH–CpG associations (P < 9 × 10−8), 25 of which were validated in survivors of African ancestry (P < 0.05). Thirteen CpGs were associated with all three SDOH factors and resided at pleiotropic loci in cigarette smoking–related genes (e.g., CLDND1 and CPOX). After accounting for smoking and body mass index, these associations remained significant with attenuated effect sizes. Seven of 13 CpGs were associated with gene expression level based on 57 subsamples with blood RNA sequencing data available. In conclusion, DNAm signatures, many resembling the effect of tobacco use, were associated with SDOH factors among survivors of childhood cancer, thereby suggesting that biologically distal SDOH factors influence health behaviours or related factors, the epigenome, and subsequently survivors' health.

Background: Although survivors of childhood cancer are at risk of chronic pain, the impact of pain on daily functioning is not well understood. Methods: A total of 2836 survivors (mean age, 32.2 years [SD, 8.5 years]; mean time since diagnosis, 23.7 years [SD, 8.2 years]) and 343 noncancer community controls (mean age, 35.5 years [SD, 10.2 years]) underwent comprehensive medical, neurocognitive, and physical performance assessments, and completed measures of pain, health‐related quality of life (HRQOL), and social functioning. Multinomial logistic regression models, using odds ratios and 95% confidence intervals (95% CIs), examined associations between diagnosis, treatment exposures, chronic health conditions, and pain. Relative risks (RRs) between pain and neurocognition, physical performance, social functioning, and HRQOL were examined using modified Poisson regression. Results: Approximately 18% of survivors (95% CI, 16.1%‐18.9%) versus 8% of controls (95% CI, 5.0%‐10.9%) reported moderate to very severe pain with moderate to extreme daily interference (P <.001). Severe and life‐threatening chronic health conditions were associated with an increased likelihood of pain with interference (odds ratio, 2.03; 95% CI, 1.62‐2.54). Pain with daily interference was found to be associated with an increased risk of impaired neurocognition (attention: RR, 1.88 [95% CI, 1.46‐2.41]; and memory: RR, 1.65 [95% CI, 1.25‐2.17]), physical functioning (aerobic capacity: RR, 2.29 [95% CI, 1.84‐2.84]; and mobility: RR, 1.71 [95% CI, 1.42‐2.06]), social functioning (inability to hold a job and/or attend school: RR, 4.46 [95% CI, 3.45‐5.76]; and assistance with routine and/or personal care needs: RR, 5.64 [95% CI, 3.92‐8.10]), and HRQOL (physical: RR, 6.34 [95% CI, 5.04‐7.98]; and emotional: RR, 2.83 [95% CI, 2.28‐3.50]). Conclusions: Survivors of childhood cancer are at risk of pain and associated functional impairments. Survivors should be screened routinely for pain and interventions targeting pain interference are needed. Adult survivors of childhood cancer are at an increased risk of moderate to very severe pain compared with community controls. In long‐term survivors, pain significantly interferes with multiple aspects of daily functioning. [ABSTRACT FROM AUTHOR]

Study Question: Do genetic variations in the DNA damage response pathway modify the adverse effect of alkylating agents on ovarian function in female childhood cancer survivors (CCS)?Summary Answer: Female CCS carrying a common BR serine/threonine kinase 1 (BRSK1) gene variant appear to be at 2.5-fold increased odds of reduced ovarian function after treatment with high doses of alkylating chemotherapy.What Is Known Already: Female CCS show large inter-individual variability in the impact of DNA-damaging alkylating chemotherapy, given as treatment of childhood cancer, on adult ovarian function. Genetic variants in DNA repair genes affecting ovarian function might explain this variability.Study Design, Size, Duration: CCS for the discovery cohort were identified from the Dutch Childhood Oncology Group (DCOG) LATER VEVO-study, a multi-centre retrospective cohort study evaluating fertility, ovarian reserve and risk of premature menopause among adult female 5-year survivors of childhood cancer. Female 5-year CCS, diagnosed with cancer and treated with chemotherapy before the age of 25 years, and aged 18 years or older at time of study were enrolled in the current study. Results from the discovery Dutch DCOG-LATER VEVO cohort (n = 285) were validated in the pan-European PanCareLIFE (n = 465) and the USA-based St. Jude Lifetime Cohort (n = 391).Participants/materials, Setting, Methods: To evaluate ovarian function, anti-Müllerian hormone (AMH) levels were assessed in both the discovery cohort and the replication cohorts. Using additive genetic models in linear and logistic regression, five genetic variants involved in DNA damage response were analysed in relation to cyclophosphamide equivalent dose (CED) score and their impact on ovarian function. Results were then examined using fixed-effect meta-analysis.Main Results and the Role Of Chance: Meta-analysis across the three independent cohorts showed a significant interaction effect (P = 3.0 × 10-4) between rs11668344 of BRSK1 (allele frequency = 0.34) among CCS treated with high-dose alkylating agents (CED score ≥8000 mg/m2), resulting in a 2.5-fold increased odds of a reduced ovarian function (lowest AMH tertile) for CCS carrying one G allele compared to CCS without this allele (odds ratio genotype AA: 2.01 vs AG: 5.00).Limitations, Reasons For Caution: While low AMH levels can also identify poor responders in assisted reproductive technology, it needs to be emphasized that AMH remains a surrogate marker of ovarian function.Wider Implications Of the Findings: Further research, validating our findings and identifying additional risk-contributing genetic variants, may enable individualized counselling regarding treatment-related risks and necessity of fertility preservation procedures in girls with cancer.Study Funding/competing Interest(s): This work was supported by the PanCareLIFE project that has received funding from the European Union's Seventh Framework Programme for research, technological development and demonstration under grant agreement no 602030. In addition, the DCOG-LATER VEVO study was funded by the Dutch Cancer Society (Grant no.

Background: Treatment characteristics such as cranial radiation therapy (CRT) do not fully explain adiposity risk in childhood acute lymphoblastic leukemia (ALL) survivors. This study was aimed at characterizing genetic variation related to adult body mass index (BMI) among survivors of childhood ALL. Methods: Genetic associations of BMI among 1458 adult survivors of childhood ALL (median time from diagnosis, 20 years) were analyzed by multiple approaches. A 2‐stage genome‐wide association study in the Childhood Cancer Survivor Study (CCSS) and the St. Jude Lifetime Cohort Study (SJLIFE) was performed. BMI was a highly polygenic trait in the general population. Within the known loci, the BMI percent variance explained was estimated, and additive interactions (chi‐square test) with CRT in the CCSS were evaluated. The role of DNA methylation in CRT interaction was further evaluated in a subsample of ALL survivors. Results: In a meta‐analysis of the CCSS and SJLIFE, 2 novel loci associated with adult BMI among survivors of childhood ALL (LINC00856 rs575792008 and EMR1 rs62123082; PMeta < 5E–8) were identified. It was estimated that the more than 700 known loci explained 6.2% of the variation in adult BMI in childhood ALL survivors. Within the known loci, significant main effects for 23 loci and statistical interactions with CRT at 9 loci (P < 7.0E–5) were further identified. At 2 CRT‐interacting loci, DNA methylation patterns may have differed by age. Conclusions: Adult survivors of childhood ALL have genetic heritability for BMI similar to that observed in the general population. This study provides evidence that treatment with CRT can modify the effect of genetic variants on adult BMI in childhood ALL survivors. Adult survivors of childhood acute lymphoblastic leukemia, particularly those treated with cranial radiation, are at increased risk for obesity. This study provides evidence that the body mass index in adult survivors of childhood acute lymphoblastic leukemia is a genetically heritable trait similar to that in the general population and that the effect of genetic loci from the general population may be modified by treatment with cranial radiation.

Background: Suicide is a serious public health concern. An increased risk of suicide ideation previously has been reported among survivors of childhood cancer. Methods: Suicide mortality was assessed for all potentially eligible survivors (those aged ≥18 years who were ≥5 years after their cancer diagnosis; 7312 survivors). Risk factors for acute suicidal ideation were assessed among clinically evaluated survivors (3096 survivors) and the prevalence of acute ideation was compared with that of community controls (429 individuals). The prevalence of 12‐month suicidality was assessed among survivors who could be compared with population data (1255 survivors). Standardized mortality ratios compared rates of suicide mortality among survivors with those of the general population. Risk ratios (RRs) and 95% confidence intervals (95% CIs) derived from generalized linear models identified risk factors associated with acute suicidal ideation. Standardized incidence ratios (SIRs) compared the prevalence of 12‐month suicidality among survivors with that of a matched sample from the general population. Results: Survivors reported a similar 12‐month prevalence of ideation compared with the general population (SIR, 0.68; 95% CI, 0.35‐1.01) and a lower prevalence of suicidal behaviors (planning: SIR, 0.17 [95% CI, 0.07‐0.27]; attempts: SIR, 0.07 [95% CI, 0.00‐0.15]) and mortality (standardized mortality ratio, 0.60; 95% CI, 0.34‐0.86). Among survivors, depression (RR, 12.30; 95% CI, 7.89‐19.11), anxiety (RR, 2.19; 95% CI, 1.40‐3.40), and financial stress (RR, 1.47; 95% CI, 1.00‐2.15) were found to be associated with a higher prevalence of acute suicidal ideation. Conclusions: Survivors of childhood cancer were found to be at a lower risk of suicidal behaviors and mortality, yet endorsed a prevalence of ideation similar to that of the general population. These results are in contrast to previous findings of suicidal ideation among survivors and support the need for further research to inform screening strategies and interventions. Lay Summary: The purpose of the current study was to compare the risk of suicidal ideation, behaviors, and mortality in adult survivors of childhood cancer with those of the general population. Risk factors associated with suicidal ideation among survivors of childhood cancer also were examined.Survivors of childhood cancer reported a similar risk of ideation compared with the general population, but a lower risk of suicidal behaviors and mortality. Psychological health and financial stressors were found to be risk factors associated with suicidal ideation.Although adult survivors of childhood cancer did not report a greater risk of suicidality compared with the general population, psychosocial care in survivorship remains essential. Long‐term survivors of childhood cancer do not appear to be at an increased risk of suicidality. However, despite its low prevalence, death by suicide can be prevented and the development of interventions to address suicidality remains important for survivors. [ABSTRACT FROM AUTHOR]

Background: To the authors' knowledge, few studies to date have examined long-term neurocognitive outcomes in survivors of childhood soft-tissue sarcoma.Methods: A total of 150 survivors (41% of whom were female with a mean current age of 33 years [SD, 8.9 years] and a time since diagnosis of 24 years [SD, 8.7 years]) and 349 community controls (56% of whom were female with a mean current age of 35 years [SD, 10.2 years]) completed comprehensive neuropsychological testing, echocardiography, electrocardiography, pulmonary function tests, endocrine evaluation, and physical examination. Patient-reported outcomes of health-related quality of life (HRQOL) and social attainment were collected. Survivors were compared with norms and controls on neurocognitive outcomes using general linear models, and on HRQOL and social attainment using modified Poisson models. The impacts of treatment and chronic health conditions on outcomes were examined using multivariable general linear models (effect size was expressed as unstandardized β estimates that reflected the unit of change from a mean of 0 and an SD of 1) and modified Poisson models (effect size expressed as relative risks).Results: Compared with controls and population norms, survivors demonstrated lower performance on measures of verbal reasoning (mean z score, -0.45 [SD, 1.15]; P < .001) mathematics (mean z score, -0.63 [SD, 1.07]; P < .001), and long-term memory (mean z score, -0.37 [SD, 1.14]; P < .001). Cumulative anthracycline exposure (per 100 mg/m2 ) was found to be associated with poorer verbal reasoning (β = -0.14 z scores; P = .04), reading (β = -0.09 z score; P = .04), and patient-reported vitality (relative risk, 1.32; 95% CI, 1.09-1.59). Neurologic and neurosensory chronic conditions were associated with poorer mathematics (neurologic conditions: β = -0.63 z score [P = 0.02]; and hearing impairment: β = -0.75 z scores [P < 0.01]). Better cognitive performance was associated with higher social attainment.Conclusions: Long-term survivors of soft-tissue sarcoma are at risk of neurocognitive problems and poor HRQOL associated with anthracycline treatment and chronic health conditions.

Background: To the authors' knowledge, social network status in adolescent and young adult (AYA) cancer survivors has not been adequately studied to date. The authors developed and validated a functional social network index (FSNI) for AYA survivors, and compared its performance with that of 2 traditional indices (density and betweenness centrality).Methods: A total of 102 AYA survivors and 102 noncancer controls who were matched for age, sex, and race were recruited from an Internet panel. Each participant reported relationships with up to 25 close friends and/or relatives. The authors developed a FSNI with reported marital status, contact frequency with friends/relatives, available resources for emotional and tangible support, and available resources for physical activity and weight management advice. Linear regression was used to analyze associations between the FSNI and cancer diagnoses, treatments, and coping skills.Results: Based on the FSNI, survivors were found to have more available resources for emotional support (beta [b] = 3.02; P = .003), tangible support (b = 4.17; P<.001), physical activity advice (b = 3.94; P<.001), and weight management advice (b = 4.10; P<.001) compared with noncancer controls. Survivors of lymphoma had the largest FSNI, whereas survivors of central nervous system malignancies had the smallest (b = 2.77; P = .02). A higher FSNI was associated with better coping skills: less denial (b = 0.10; P = .01), using emotional support (b = 0.08; P = .04), using instrumental support (b = 0.12; P<.001), less behavioral disengagement (b = 0.08; P = .04), venting of emotions (b = 0.10; P = .004), positive reframing (b = 0.12; P = .003), planning for the future (b = 0.08; P = .03), and religious engagement (b = 0.16; P<.001). Density and betweenness centrality indices demonstrated neither significant differences in social networks between cancer survivors and controls (all P values >.05) nor significant associations with coping skills (all P values >.05).Conclusions: The FSNI appears to provide a better social network assessment for AYA cancer survivors than traditional indices.

Background: Children with non-Hodgkin lymphoma (NHL) undergo treatment with central nervous system-directed therapy, the potentially neurotoxic effects of which have not been reported in NHL survivors.Methods: NHL survivors (n = 187) participating in the St. Jude Lifetime Cohort who were 10 or more years from their diagnosis and were 18 years old or older underwent neurocognitive, emotional distress (Brief Symptom Inventory 18), and health-related quality of life (HRQOL) assessments (36-Item Short Form Health Survey). Age-adjusted z scores were compared with community controls (n = 181) and normative data. Treatment exposures were abstracted from medical records. Models adjusted for the age, sex, and time from diagnosis were used to calculate the risk of impairment.Results: The mean ages at evaluation were similar for the survivors and the controls (35.7 ± 8.9 vs 35.5 ± 11.0 years; P = .86). Survivors were 25.2 ± 8.8 years from their diagnosis: 43 (23%) received cranial radiation, 70 (37%) received high-dose methotrexate, 40 (21%) received high-dose cytarabine, and 151 (81%) received intrathecal chemotherapy. Survivors' intelligence and attention were within normal limits; however, their memory, executive function, processing speed, and academics were impaired in comparison with both population norms and community controls (P values < .05). Treatment-related exposures were not associated with neurocognitive function; however, neurocognitive impairment was associated with lower educational attainment, unemployment, and occupational status (P values < .03). Slower processing speed and worse self-reported executive function were associated with symptoms of depression (P values ≤ .003) and poorer HRQOL (P values < .05).Conclusions: Adult survivors of childhood NHL experience impaired neurocognitive function, which is associated with lower social attainment and poor HRQOL. Early-detection and intervention strategies are recommended. Cancer 2017. © 2017 American Cancer Society. [ABSTRACT FROM AUTHOR]

Background: Long-term survivors of childhood acute lymphoblastic leukemia (ALL) are at risk for neurocognitive impairment, which may be associated with fatigue, sleep problems, systemic inflammation, and oxidative stress. We examined these associations among survivors of childhood ALL treated with chemotherapy only.Methods: Survivors of childhood ALL (male, n = 35 and female, n = 35; mean age, 14.3 years [standard deviation, 4.7 years] and mean years from diagnosis, 7.4 years [standard deviation, 1.9 years]) completed neurocognitive testing, behavioral ratings, and reported sleep quality and fatigue symptoms 5 years after diagnosis. Serum was collected concurrently and assayed for interleukin (IL)-1β and IL-6, tumor necrosis factor α (TNF-α), high-sensitivity C-reactive protein (hsCRP), malondialdehyde, myeloperoxidase, and oxidized low-density lipoprotein. General linear modeling was used to assess associations among biomarkers and functional outcomes, adjusting for age and stratified by sex.Results: Survivors performed worse than population norms on executive function and processing speed and reported more behavioral problems (P < .05 adjusted for multiple comparison). In female survivors, fatigue was associated with poor executive function (r = 0.41; P = .02), processing speed (r = 0.56; P < .001), and attention (r = 0.36-0.55; P < .05). Female survivors with frequent nighttime awakening displayed more inattention (P = .01), hyperactivity (P = .03), and aggression (P = .01). Worse executive function, processing speed, and behavioral symptoms were observed in female survivors with higher levels of IL-6, IL-1β, and hsCRP (P < .05). Male survivors with high levels of TNF-α demonstrated worse organization (P = .03), but no significant associations between neurocognitive outcomes and sleep/fatigue measures were observed.Conclusion: Neurocognitive function in female survivors of childhood ALL appears more susceptible to the effects of sleep disturbance and fatigue. Systemic inflammation may play a role in neurocognitive impairment and behavioral symptoms. Cancer 2017;123:3410-9. © 2017 American Cancer Society. [ABSTRACT FROM AUTHOR]

Research has shown that self-esteem and hopefulness are positively related among female childhood cancer survivors (CCS) and contribute to their health-related quality of life (HRQOL). HRQOL remains a significant outcome of treatment for CCS. This study examined the relationships among self-esteem, hopefulness, and HRQOL in young adult female CCS to inform the development of evidence-based practice guidelines for pediatric oncology nursing practice. An online survey was conducted with a sample of young adult female CCS from 58 treatment centers across the United States at 4 time points: at baseline and at 6 weeks, 3 months, and 6 months after initial measurement time. The relationships between self-esteem, hopefulness, and HRQOL were statistically significant (Time 1, P = .05; Times 2, 3, and 4, P = .01) across all measurement times. These findings identify hopefulness and self-esteem as determinants of HRQOL and suggest that caring practices among pediatric oncology nurses that support psychosocial adjustment through promoting self-esteem and hopefulness have the potential to support HRQOL among young adult female CCS. These outcomes support the development of evidence-based practice guidelines to influence HRQOL outcomes among these survivors. [ABSTRACT FROM AUTHOR]

Objective The current study investigated the occurrence of emotional distress in parents of long-term survivors of childhood acute lymphoblastic leukemia (ALL) and identified factors associated with parent emotional distress symptoms. Methods Parents of 127 long-term survivors of childhood ALL treated on a chemotherapy-only protocol at St. Jude Children's Research Hospital participated in the study. Parents completed standard ratings of emotional distress, caregiver strain, and child physical, emotional, and psychosocial functioning. Multivariable hierarchical linear regression analyses were used to examine associations between symptoms of caregiver strain, survivor functioning, and parent emotional distress. Covariates included parent education, survivor age, survivor sex, and time since childhood cancer diagnosis. Results On average, few parents reported significant symptoms of emotional distress. Clinically significant levels of anxiety and depression were reported by 7.1% and 3.1% of parents, respectively. Only 3.9% of parents endorsed significant symptoms of posttraumatic stress. Perceived caregiver strain was significantly associated with symptoms of parent anxiety, depression, and posttraumatic stress. Parent-report of child emotional functioning was significantly associated with symptoms of parent anxiety. Conclusions Most parents of long-term survivors of ALL exhibit low levels of emotional distress in the context of rates observed in the general population. Perceived caregiver strain was significantly associated with parent emotional distress. Further research is required to examine specific sources of caregiver strain, as well as other risk and protective factors associated with parent emotional distress symptoms.

Objectives Characterize longitudinal changes in the use of medical care in adult survivors of childhood cancer. Data Sources The Childhood Cancer Survivor Study, a retrospective cohort study of 5+ year survivors of childhood cancer. Study Design Medical care was assessed at entry into the cohort (baseline) and at most recent questionnaire completion. Care at each time point was classified as no care, general care, or survivor-focused care. Data Collection There were 6,176 eligible survivors. Multivariable models evaluated risk factors for reporting survivor-focused care or general medical care at baseline and no care at follow-up; and survivor-focused care at baseline and general care at follow-up. Principal Findings Males ( RR, 2.3; 95 percent CI 1.8-2.9), earning <$20,000/year ( RR, 1.6; 95 percent CI 1.2-2.3) or ≤high school education ( RR, 2.5; 95 percent CI 1.6-3.8 and RR 2.0; 95 percent CI 1.5-2.7 for

BACKGROUND Retinoblastoma has a 5-year survival rate exceeding 95%, yet little is known about long-term functional outcomes for these patients. METHODS Sixty-nine adult survivors of retinoblastoma (mean age, 33 years; mean years post-diagnosis, 31) who had enrolled in the St. Jude Lifetime Cohort Study completed clinical cognitive evaluations and questionnaires assessing adult social attainment. Scores on all cognitive measures were converted to z-scores (M = 0, SD = 1) using age-adjusted normative data. Multivariable linear regression analyses, adjusted for age at diagnosis and disease laterality, were used to examine associations between disease and treatment exposures and cognitive outcomes. RESULTS Retinoblastoma survivors performed within normative expectations across most cognitive domains. In multivariable models, adjusted for disease laterality, survivors diagnosed at ≤1 year of age performed significantly better on measures of short-term verbal memory (β = 0.87, P<.01), long-term verbal memory (β = 0.66, P = .02), verbal learning (β = 0.67, P = .02), and verbal reasoning abilities (β = 0.79, P<.01) compared with survivors diagnosed at >1 year of age. In multivariable models, restricted to bilateral survivors and adjusted for age at diagnosis, whole brain radiation exposure was significantly associated with poorer performance on tasks of short-term verbal memory (β = −0.003, P = .03) and long-term verbal memory (β = −0.003, P = .01). Reported social attainment was consistent with adult developmental expectations. CONCLUSIONS Adult survivors of retinoblastoma demonstrate few cognitive or social attainment deficits decades following diagnosis and treatment. Findings suggest the potential for neural reorganization following early insult to the visual system as well as vulnerability of the developing brain to low dose radiation exposure. Early intervention and rehabilitation will be important for these patients. Cancer 2015;121:123-131. © 2014 American Cancer Society. [ABSTRACT FROM AUTHOR]

Objectives: To determine whether unique groups of adult childhood cancer survivors could be defined on the basis of modifiable cognitive, affective, and motivation indicators. Secondary objectives were to examine to what extent group membership co-varied with more static variables (e.g. demographics, disease, and treatment) and predicted intent for subsequent medical follow-up. Methods: Using latent class analysis of data from 978 participants (ages, 18-52 years; mean, 31; and SD, 8) in the Childhood Cancer Survivor Study, we classified survivors according to their worries about health, perceived need for follow-up care, health motivation, and background variables. Intent to participate in medical follow-up, as a function of class membership, was tested using equality of proportions. Results: The best-fitting model (BIC = 18 540.67, BLMRT = <0.001) was characterized by three distinctive survivor classes (worried, 19%; self-controlling, 26%; and collaborative, 55%) and three significant class covariates (gender, perceptions of health, and severity of late effects). A smaller proportion of survivors in the self-controlling group (81%) than in the worried (90%) ( P = 0.015) and collaborative (88%) ( P = 0.015) groups intended to obtain a routine medical checkup. A smaller proportion of survivors in the self-controlling group (32%) than in the collaborative (65%) ( P = <0.001) and worried (86%) ( P = <0.001) groups planned a cancer-related check-up. A smaller proportion of survivors in the collaborative group (65%) than in the worried group (86%) ( P = <0.001) were likely to obtain a cancer-related check-up. Conclusions: Childhood cancer survivors can be classified according to the modifiable indicators. The classification is distinctive, predicts intent for future medical follow-up, and can inform tailored interventions. Copyright © 2011 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

The majority of children, adolescents, and young adults diagnosed with cancer will become long-term survivors with many potential years of life ahead of them. Their journey from health through diagnosis and treatment to survivorship involves multiple transitions. Transitional services that should be available throughout this journey include health-related education, health surveillance and screening, management of cancer-related complications, and psychosocial support relevant to their developmental needs. Survivors require lifelong care that focuses not only on the medical risks arising from their cancer therapy, but also the psychosocial, educational, and vocational implications of surviving cancer. Because many community health care providers lack familiarity with the health risks associated with childhood or adolescent/young adult cancer, survivors must have sufficient health knowledge to advocate for risk-based cancer-related follow-up; the provision of a treatment summary and care plan at the conclusion of their cancer therapy is an important tool for facilitating this process. The availability of resources for survivors varies by geography, health care system, and survivor characteristics. Adolescents and young adults who receive their care outside of a pediatric cancer center have particularly limited access. The limitations in cancer center resources (along with survivor preference) strongly suggest that the long-term care of survivors will need to be shared between the cancer centers and primary care providers in survivors' communities. Cancer 2011;117(10 suppl):2335-41. © 2011 American Cancer Society. Survivors of cancer in childhood, adolescence, or young adult life require lifelong care that focuses not only on the medical risks that arise from their cancer therapy but also on the psychosocial, educational, and vocational implications of surviving cancer. Limitations in cancer center resources (along with survivor preference) strongly suggest that this care will need to be shared between cancer centers and primary care providers in survivors' communities.

BACKGROUND: Lack of health insurance is a key barrier to accessing care for chronic conditions and cancer screening. The influence of insurance type (private, public, none) on survivor-focused and general preventive health care in adult survivors of childhood cancer was examined. METHODS: The Childhood Cancer Survivor Study is a retrospective cohort study of childhood cancer survivors diagnosed between 1970 and 1986. Among 8425 adult survivors, the relative risk (RR) and 95% confidence interval (CI) of receiving survivor-focused and general preventive health care were estimated for uninsured (n = 1390) and publicly insured (n = 640), compared with for the privately insured (n 1/4 6395) RESULTS: Uninsured survivors were less likely than those privately insured to report a cancer-related visit (adjusted RR, 0.83; 95% CI, 0.75-0.91) or a cancer center visit (adjusted RR, 0.83; 95% CI, 0.71-0.98). Uninsured survivors had lower levels of utilization in all measures of care in comparison with privately insured. In contrast, publicly insured survivors were more likely to report a cancer-related visit (adjusted RR, 1.22; 95% CI, 1.11-1.35) or a cancer center visit (adjusted RR, 1.41; 95% CI, 1.18-1.70) than were privately insured survivors. Although publicly insured survivors had similar utilization of general health examinations, they were less likely to report a Papanicolaou test or a dental examinations CONCLUSIONS: Among this large, socioeconomically diverse cohort, publicly insured survivors utilize survivor-focused health care at rates at least as high as survivors with private insurance. Uninsured survivors have lower utilization of both survivor-focused and general preventive health care. [ABSTRACT FROM AUTHOR]

The article presents a study which evaluates the knowledge of long-term pediatric cancer survivors on blood transfusion history and hepatitis C virus (HCV) screening. The study use questionnaires to evaluate the knowledge of cancer survivor on HCV screening history. The result of the study shows that the pediatric cancer survivors are uninformed of their blood transfusion history wherein 31% are uncertain, 70% reported no history, and only 29% has HCV testing.

The article focuses on the usefulness of human papillovirus (HPV) vaccines to childhood cancer survivors. It notes that HPV is the most common sexually transmitted infection and the cause of cervical cancer among women. It stresses that HPV vaccine uptake is important among cancer survivors at risk for HPV-related complications. These high-risk groups include women who had undergone liver, renal, and lung transplantation and youth undergoing hematopoietic stem cell transplantation (HSCT).

The article discusses the significance of physical activity participation to childhood cancer survivors. The authors claim that physical activity is important to survivors because inactivity may compound cancer/treatment-related late effects. They add that for those survivors who have difficulty in participating physical activity are need to be identified so that risk-based guidelines for physical activity can be developed and implemented.

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.

Background Pediatric and young adult (PAYA) cancer survivors may have an earlier onset of chronic diseases compared with the general population. We compared the age at cervical cancer diagnosis between PAYA cancer survivors and females in the general US population. Methods We used longitudinal data from 9 population-based registries of the Surveillance, Epidemiology, and End Results program collected between 1973 and 2010. PAYA cancer survivors were females diagnosed with any cancer before age 30 years, survived at least 5 years post-diagnosis, and were subsequently diagnosed with invasive cervical cancer (n = 46). The general US population comprised females who were diagnosed with invasive cervical cancer as the primary malignancy (n = 26,956). We estimated the difference in median age at diagnosis (β50) and bootstrap 95% confidence limits (CL) of invasive cervical cancer after adjustment for year of diagnosis and race. Results The median age at diagnosis of invasive cervical cancer was 33 years for female PAYA cancer survivors and 40 years for females in the general US population (β50 = - 7.0, 95% CL: - 11, - 3.2). Similar differences were observed across subgroups of stage and histologic subtype of invasive cervical cancer. Conclusion Our results suggest that PAYA cancer survivors are diagnosed with invasive cervical cancer at a substantially younger age compared with females without a prior cancer diagnosis in the general US population. This issue warrants further study, and could have implications for determining age at initiation or frequency of cervical cancer screening if younger age at diagnosis is attributable to an underlying biological phenomenon.
