STUDY OBJECTIVES To identify specific toxic atmospheric emissions and their industrial sources in Great Britain. To link them with each other and with the birth addresses of children dying from cancer. To identify specific causal agents and sources. DESIGN Birth and death addresses of children dying from cancer were linked to emissions hotspots for specific chemicals: and to related source in...
OBJECTIVE The aetiology of childhood cancer remains largely unknown but recent research indicates that uterine environment plays an important role. We aimed to examine the association between the Apgar score at 5 min after birth and the risk of childhood cancer. DESIGN Nationwide population-based cohort study. SETTING Nationwide register data in Denmark and Sweden. STUDY POPULATION All li...
background: geographic differences in the incidence of cancers may suggest unique genetic or environmental exposures that impact the risk of acquiring cancer. this research aims to determine the incidence rate and geographical distribution of common cancers among iranian children. methods: in this ecological study, we extracted data that pertained to the incidence rate of common cancers among c...
Overcoming childhood cancers is critically dependent on the state of research. Understanding how, with whom and what the research community is doing with childhood cancers is essential for ensuring the evidence-based policies at national and European level to support children, their families and researchers. As part of the European Union funded EUROCANCERCOMS project to study and integrate canc...
OBJECTIVE The aim of this study was to characterise rates of late mortality and second cancers in an Australian cohort of childhood cancer survivors and compare these to rates observed in the New South Wales population. DESIGN, SETTING AND PARTICIPANTS Records for 896 childhood cancer survivors treated at the Sydney Children's Hospital between 1972 and 1999 were linked to the National Death I...
Little is known about environmental causes of childhood cancer. This is probably due to the relative rarity of cancer in children. In the United States, cancer incidence in adults is over 20 times greater than cancer incidence in children. The situation is compounded by the fact that two groups of cancers, leukemias and brain and spinal tumors, account for half of all childhood cancers. The rar...
(Abstracted from BMJ 2020;371:m4060) Birth defects are strong risk factors for childhood cancers. While past studies have identified associations between birth and cancer in children, few looked at these into adulthood.
Measurement of incidence rates of childhood cancer in Africa is difficult. The study 'Cancer of Childhood in sub Saharan Africa' [Stefan C, Bray F, Ferlay J, Parkin DM and Liu B (2017) Cancer of Childhood in sub-Saharan Africaecancer11(755)] brings together results from 16 population-based registries which, as members of the African Cancer Registry Network (AFCRN), have been evaluated as achiev...
Background: Public concern about possible increases in childhood cancer incidence in the United States led us to examine recent incidence and mortality patterns. Methods: Cancers diagnosed in 14 540 children under age 15 years from 1975 through 1995 and reported to nine population-based registries in the National Cancer Institute’s Surveillance, Epidemiology, and End Results Program were invest...
BACKGROUND In utero exposure to radiation is known to increase risks of childhood cancers, and childhood exposure is associated with increased risks of adult-onset cancers. However, little is known about whether in utero exposure to radiation increases risks of adult-onset cancers. METHODS Solid cancer incidence rates were examined among survivors of the atomic bombings of Hiroshima and Nagas...
