Urban green spaces and childhood leukemia incidence: A population-based case-control study in Madrid.
2021
Abstract Background Childhood leukemia is the most common childhood cancer. To date, few risk factors related to predisposition have been identified; therefore, new hypotheses should be considered. Objective To explore the possible relationship of residential proximity to urban green spaces on childhood leukemia. Methods We conducted a population-based case control study in the metropolitan area of Madrid from 2000 to 2015. It included 383 incident cases and 1935 controls, individually matched by birth year, sex and area of residence. Using the geographical coordinates of the participants’ home residences, we built a proxy for exposure with four distances (250 m, 500 m, 750 m and 1 km) to u…
Geographical variability in survival of European children with central nervous system tumours
2017
Survival for childhood central nervous system (CNS) tumours varies across Europe, partly because of the difficulty of distinguishing malignant from non-malignant disease. This study examines bias in CNS tumours survival analysis to obtain the reliable and comparable survival figures. We analysed survival data for about 15, 000 children (age <15) diagnosed with CNS between 2000 and 2007, from 71 population- based cancer registries in 27 countries. We selected high- quality data based on registry- specific data quality indicators and recorded observed 1-year and 5-year survival by countries and CNS entity. We provided age- adjusted survival and used a Cox model to calculate the hazard ratios …
