Under 2% of all cancers in industrialized countries occur in childhood and adolescence, but they account for a much larger proportion of total population life years potentially lost to cancer. Total incidence is about 160 per million in children and 200 per million in adolescents. In children, leukaemias account for one third of all malignancies and CNS tumours for one quarter. In adolescents, lymphomas account for one quarter of cases and leukaemias, CNS tumours, and carcinomas each for about 15%. Five-year survival exceeds 80% for many childhood and some adolescent cancers. Although survival of adolescents is high overall, survival for several types of cancer is markedly lower than in children. Infants under a year of age also tend to have lower survival. Excess mortality continues beyond 25 years from diagnosis of childhood cancer. The risk of developing a second primary cancer is about six times that in the general population. The causes of most childhood cancers remain unknown. The principal established exogenous causes are ionizing radiation, ultraviolet radiation from sunlight, and certain viruses. Up to 10% of children and adolescents with cancer may have germline mutations in cancer predisposition genes. If one child in a family has cancer, then that child’s siblings have approximately double the risk of the general population for developing childhood cancer, but this could well be entirely accounted for by familial syndromes. Significantly raised or reduced risks of childhood cancers have been linked to polymorphic variants of certain genes, though many of these associations remain to be replicated.

Childhood Cancer Survivor Study

Overall survival for all childhood cancers has substantially increased with nearly 80 % of children surviving to five years following diagnosis, compared with 30 % 50 years ago. Unfortunately this comes at a cost; the overall Standardised Mortality Ratio (SMR) was 8.4 for childhood cancer survivors compared with the general population and increases in cause-specific mortality were seen for deaths due to second malignancy and cardiotoxicity. The incidence of chronic morbidities in the US Childhood Cancer Survivor Study (CCSS) cohort was 62.3 % after follow-up for 26.6 years. While many children will escape these organ toxicities, a significant proportion will require surveillance and management of treatment morbidities. It is the responsibility of those who treat childhood cancer to understand the effects of treatment and provide effective services to maximise the potential of these young people.

Abstract Background The aetiology of most childhood cancers is largely unknown. Spatially varying environmental factors such as traffic-related air pollution, background radiation and agricultural pesticides might contribute to the development of childhood cancer. We investigated the spatial variation of childhood cancers in Switzerland using exact geocodes of place of residence. Methods We included 5,947 children diagnosed with cancer during 1985-2015 at age 0-15 from the Swiss Childhood Cancer Registry. We modelled cancer risk using log-Gaussian Cox processes and indirect standardization to adjust for age and year of diagnosis. We examined whether the modelled spatial variation of risk can be explained by ambient air concentration of NO 2 , natural background radiation, area-based socio-economic position (SEP), linguistic region, years of existing general cancer registration in the canton or degree of urbanization. Results For all childhood cancers combined, the posterior median relative risk (RR), compared to the national level, varied by location from 0.83 to 1.13 (min to max). Corresponding ranges were 0.96 to 1.09 for leukaemia, 0.90 to 1.13 for lymphoma, and 0.82 to 1.23 for CNS tumours. The covariates considered explained 72% of the observed spatial variation for all cancers, 81% for leukaemia, 82% for lymphoma and 64% for CNS tumours. There was evidence of an association of background radiation and SEP with incidence of CNS tumours, (1.19;0.98-1.40) and (1.6;1-1.13) respectively. Conclusion Of the investigated diagnostic groups, childhood CNS tumours show the largest spatial variation in Switzerland. The selected covariates only partially explained the observed variation of CNS tumours suggesting that other environmental factors also play a role.

Cvd Mortality

Abstract Aims  Our aim was to assess the risk of cardiovascular disease (CVD) mortality in US 5-year survivors of adolescent and young adult (AYA) cancer compared with those of the general population and contemporaneous 5-year survivors of childhood cancer. Methods and results  A total of 160 834 5-year AYA cancer survivors (aged 15–39 years at diagnosis) were included, representing 2 239 390 person-years of follow-up. Overall, 2910 CVD deaths occurred, which was 1.4-fold [95% confidence interval (CI) 1.3–1.4] that expected in the general population, corresponding to 3.6 (95% CI 3.2–3.9) excess CVD deaths per 10 000 person-years. The highest risk of cardiac mortality was experienced after Hodgkin’s lymphoma (HL), and the highest risk of cerebrovascular mortality was observed with central nervous system (CNS) tumours. Even survivors in their 6th and 7th decades of life, the risk of CVD mortality remained markedly higher than that of the matched general population. Competing risk analysis showed that the cumulative mortality of CVD was elevated among AYA cancer survivors compared with childhood cancer survivors during the whole study period. Conclusion  Long-term AYA cancer survivors have a greater risk of CVD mortality than the US general population and childhood cancer survivors. Vulnerable subgroups, especially survivors of HL and CNS tumours, require continued close follow-up care for cardiovascular conditions throughout survivorship.

Survivors Of Childhood Cancer

Childhood cancers are uncommon, accounting for only 0.5% of all cancers in the UK. Approximately, 1500 children are diagnosed with cancer in the UK every year. Despite it being a rare occurrence, cancer still remains the largest cause of death in the 1–14 year age group, amongst whom it counts for 20% of all deaths. Although most adult cancers affect the lung, breast, bowel and prostate, the majority of childhood cancers are haematological and central nervous system (CNS) tumours. The primary care physician's role is vital across the disease trajectory, requiring them to recognize the signs and symptoms of childhood cancer, understand treatment, provide support to children and families, and finally consider the issues affecting survivors of childhood cancer.

Abstract. Evidence-based assessment is necessary as a first step for developing psychopathological studies and assessing the effectiveness of empirically validated treatments. There are several measures of obsessive-compulsive disorder (OCD) and/or symptomatology in children and adolescents, but all of them present some limitations. The Obsessive-Compulsive Inventory-Revised (OCI-R) by Foa and her colleagues has showed to be a good self-report measure to capture the dimensionality of OCD in adults and adolescents. The child version of the OCI (OCI-CV) was validated for clinical children and adolescents in 2010, showing excellent psychometric properties. The objective of this study was to examine the factor structure and invariance of the OCI-CV in the general population. Results showed a six-factor structure with one second-order factor, good consistency values, and invariance across region, age, and sex. The OCI-CV is an excellent inventory for assessing the dimensions of OCD symptomatology in general populations of children and adolescents. The invariance across sex and age warrants its utilization for research purposes.

Leucocyte telomere length (LTL) is a robust marker of biological aging and is associated with obesity and cardiometabolic risk factors in childhood and adolescence. We investigated the effect of a structured, comprehensive, multidisciplinary, personalized, lifestyle intervention program of healthy diet and physical exercise on LTL in 508 children and adolescents (239 males, 269 females; 282 prepubertal, 226 pubertal), aged 10.14 ± 0.13 years. Participants were classified as obese (n = 267, 52.6%), overweight (n = 174, 34.2%), or of normal BMI (n = 67, 13.2%) according to the International Obesity Task Force (IOTF) cutoff points and were studied prospectively for one year. We demonstrated that LTL increased significantly after 1 year of the lifestyle interventions, irrespective of gender, pubertal status, or body mass index (BMI). Waist circumference was the best negative predictor of LTL at initial assessment. The implementation of the lifestyle interventions also resulted in a significant improvement in clinical (BMI, BMI z-score and waist to height ratio) and body composition indices of obesity, inflammatory markers, hepatic enzymes, glycated hemoglobin (HbA1C), quantitative insulin sensitivity check index (QUICKI), and lipid profile in all participants. These findings indicate that the increased LTL may be associated with a more favorable metabolic profile and decreased morbidity later in life.

Obesity In Children

Background:In patients with JIA, growth impairment and variance in body composition are well-known long-term complications that may be associated with prolonged drug therapy (e.g. glucocorticoids) as well as impaired physical and psychosocial well-being. An increased accumulation of body fat represents a significant risk factor for metabolic abnormalities and a modifiable variable for a number of comorbidities. Recently, evidence has emerged in favour of the potential negative influence of overweight on the course of the disease and treatment response [1].Objectives:The study aimed a) to estimate the prevalence of underweight, overweight and obesity in children and adolescents with JIA compared to the general population, and b) to investigate correlates of patients’ weight status.Methods:A cross-sectional analysis of physicians’ recorded body weights and heights of patients with JIA enrolled in the NPRD in the year 2019 was performed. Underweight (BMI <10th), overweight (BMI >90th) and obesity (BMI >97th) were defined according to age- and sex-specific percentiles used in the German reference system. For comparison with data from the general population [2], sex- and age-matched pairs of 3-17-year-old patients and controls were generated. A multinomial logistic regression analysis was performed to examine the association between weight status and patients’ clinical and self-reported outcomes.Results:In total, data from 6.515 children and adolescents with JIA (age 11.2 ± 4.1 years, disease duration 4.9 ± 3.8 years, 67% girls, 40% persistent oligoarthritis) were included. Of these, 3.334 (age 5.9 ± 2.1 years, 52.5% girls) could be considered for matched-pair analysis. Compared with the general population, patients underweight, overweight and obesity rates were 10.6% (vs. 8.1%), 8.8% (vs. 8.5%) and 6.1% (vs. 5.7%), respectively. No significant sex differences were found in either group. Largest difference in prevalence was registered for underweight, specifically in the age group 3-6 years (12.9% patients vs. 5.9% controls). Similar to the general population, higher rates of overweight were observed in adolescent patients than in affected children (19.1% age group 11-13 vs. 8.4% age group 3-6). While the highest underweight prevalence was registered in patients with RF+ polyarthritis (16%), patients with Enthesitis-related arthritis (22%), psoriatic arthritis (21%) and systemic JIA (20%) showed the highest overweight rates (including obesity). Younger age (OR = 0.51, 95% CI = 0.31-0.83), more frequent physical activity (OR = 0.92, 95% CI = 0.85-0.99) and high parental vocational education (OR = 0.39, 95% CI = 0.18-0.80) were independently associated with a lower likelihood of being overweight/obese.Conclusion:The overall prevalence of underweight, overweight and obesity in children and adolescents with JIA is comparable to that found in the general population. Behavioural health promotion, including regular physical activity, as part of the treatment strategy in JIA should preventively already begin at preschool age and necessarily be made accessible to patients of all educational levels.References:[1]Giani T et al.

This scoping review systematically mapped evidence of the mediating and moderating effects of family characteristics on health inequalities in school-aged children and adolescents (6–18 years) in countries with developed economies in Europe and North America. We conducted a systematic scoping review following the PRISMA extension for Scoping Reviews recommendations. We searched the PubMed, PsycINFO and Scopus databases. Two reviewers independently screened titles, abstracts and full texts. Evidence was synthesized narratively. Of the 12,403 records initially identified, 50 articles were included in the synthesis. The included studies were conducted in the United States (n = 27), Europe (n = 18), Canada (n = 3), or in multiple countries combined (n = 2). We found that mental health was the most frequently assessed health outcome. The included studies reported that different family characteristics mediated or moderated health inequalities. Parental mental health, parenting practices, and parent-child-relationships were most frequently examined, and were found to be important mediating or moderating factors. In addition, family conflict and distress were relevant family characteristics. Future research should integrate additional health outcomes besides mental health, and attempt to integrate the complexity of families. The family characteristics identified in this review represent potential starting points for reducing health inequalities in childhood and adolescence.
