Educational and vocational achievement among long-term survivors of adolescent cancer in Germany

2010

Background Adolescence involves graduating from school and preparing one's professional career. The accomplishment of these tasks may be hampered by the experience of cancer. This study investigates the educational and professional achievements of German long-term survivors of adolescent cancer. Procedure Adult survivors of cancer during adolescence (n = 820, age at onset between 15 and 18 years; M = 15.8, SD = 0.9 years; age at follow-up: M = 30.4, SD = 6.0 years) were recruited through the German Childhood Cancer Registry. They completed self-reports with standard items on their educational and vocational level and their current occupational situation. Outcomes were compared to an age-mat…

Childhood Leukemia in the Vicinity of Nuclear Power Plants in Germany

2008

SUMMARY The causes of leukemia are largely unclear. The question whether leukemia rates are increased near nuclear power plants is controversial. The German Childhood Cancer Registry has published an epidemiological case-control study on childhood cancer and nuclear power plants. Method: The study was based on the distance of children's residences from nuclear power plants and addressed the question whether children under age 5 with cancer live closer, on average, to nuclear power plants than randomly selected controls. Odds Ratios (OR) for distance categories and standardized incidence ratios (SIR) were calculated. Results: An association was found between the nearness of residence to nucl…

The impact of cigarette smoking on the health of descendants

2012

This paper presents a review of the literature on the effects of cigarette smoking on the health of descendants and the possible mechanisms that lead to them. The evidence of the effects of prenatal cigarette smoke exposure on neonatal morbidity is clear. A number of birth defects have their incidence raised by maternal cigarette smoking during pregnancy. Prenatal smoke exposure also increases the risk of infant irritability, inattention, decreased response to inanimate auditory stimuli and hypertonia. In addition, the prevalence of obesity in preschool children is higher if the mother smoked during pregnancy, as well as the presence of male or female subfertility/infertility in adult life.…

Pediatric bone tumors in Germany from 1987 to 2011: incidence rates, time trends and survival

2016

AbstractBackground: Malignant bone tumors are a rare group of childhood cancer.Materials and methods: This study describes incidence rates, survival probabilities, and time trends for 1831 children below 15 years of age with a bone tumor registered at the population-based German Childhood Cancer Registry between 1987 and 2011.Results: Overall age-standardized annual incidence rate (ASR) was 5.5 per million. Osteosarcomas (ASR 2.8) and Ewing tumors (ASR 2.6) were the most frequent diagnostic groups. The incidence of bone tumors overall tended to increase slightly over time by 0.7% each year on average. Thirty-nine of the bone tumor cases reported were subsequent primaries and not included in…

Residential proximity to environmental pollution sources and risk of rare tumors in children.

2016

Background: Few epidemiologic studies have explored risk factors for rare tumors in children, and the role of environmental factors needs to be assessed. Objectives: To ascertain the effect of residential proximity to both industrial and urban areas on childhood cancer risk, taking industrial groups into account. Methods: We conducted a population-based case-control study of five childhood cancers in Spain (retinoblastoma, hepatic tumors, soft tissue sarcomas, germ cell tumors, and other epithelial neoplasms/melanomas), including 557 incident cases from the Spanish Registry of Childhood Tumors (period 1996-2011), and 3342 controls individually matched by year of birth, sex, and region of re…

Childhood leukaemia risk and residential proximity to busy roads

2018

BACKGROUND: Current evidence suggests that childhood leukaemia can be associated with residential traffic exposure; nevertheless, more results are needed to support this conclusion. OBJECTIVES: To ascertain the possible effects of residential proximity to road traffic on childhood leukaemia, taking into account traffic density, road proximity and the type of leukaemia (acute lymphoid leukaemia or acute myeloid leukaemia). METHODS: We conducted a population-based case-control study of childhood leukaemia in Spain, covering the period 1990-2011. It included 1061 incidence cases gathered from the Spanish National Childhood Cancer Registry and those Autonomous Regions with 100% coverage, and 64…

28-year incidence and time trends of childhood leukaemia in former East Germany compared to West Germany after German reunification: A study from the…

2021

Abstract Background The aetiology of childhood leukaemia is largely unknown. Analyses of geographical differences may enhance aetiologic insights. The reunification of Germany in 1990 provides a unique opportunity to evaluate incidence patterns and time trends in two merging countries with substantial lifestyle, social and socioeconomic differences. With this study we provide an extensive assessment of 28-year incidence patterns and temporal trends after the German reunification. Methods We identified all children diagnosed with a lymphoid leukaemia (LL) or acute myeloid leukaemia (AML) before the age of 15 years between 1991 and 2018 using the German Childhood Cancer Registry (N = 14,922),…

Risk factors for pediatric tumors of the central nervous system: Results from a German population-based case-control study

2001

From 1993 to 1997 we conducted two population-based case-control studies on childhood cancer and a variety of potential risk factors in Germany. One case group involved children under the age of 15 years having a tumor of the central nervous system (CNS).For both studies, one conducted in the northwestern area of Germany, the other covering the whole of West Germany, incident cases were identified from the nationwide German Childhood Cancer Registry, and controls were randomly selected from complete population registration files.In total 466 pediatric CNS tumor cases and 2,458 controls were available for analyses. We observed only few positive associations, namely, between CNS tumors and lo…

Early deaths from childhood cancer in Germany 1980-2016

2020

Abstract Background Even though the survival of childhood cancer has improved over the last decades, there are still children dying shortly after diagnosis. The aim of the study is to add to understanding of the reasons for deaths shortly after date of diagnosis. Methods Using data of the population-based German Childhood Cancer Registry (cancer below 15 years of age diagnosed between 1980 and 2016), we compared characteristics of 671 children with cancer who died within 30 days of diagnosis to 53,649 patients with childhood cancer who survived longer. In addition to a descriptive analysis, we used logistic regression with multivariable fractional polynomials to describe the relationship be…
