[Environment and pediatric cancer].
BACKGROUND
Cancer is the final result of the variable combination of two determinants: endogenous or constitutional factors and exogenous or environmental factors. Between 85 % and 96 % of pediatric cancers (PC) are probably associated with environmental risk factors (RF), most of which have not been identified. The spectacular progress made in survival in PC contrasts with the lack of knowledge of the RF implicated in its etiopathogenesis.


OBJECTIVE
1) To analyze up-to-date knowledge of the interaction among environmental RF in the etiopathogenesis of PC, and 2) to inform pediatricians of the "Environment and Pediatric Cancer" research project directed by the Pediatric Environmental Health Specialty Unit of the Hospital Infantil Universitari La Fe in Valencia (Spain).


METHODS
Current medical records focus almost exclusively on the diagnosis and treatment of cancer. The Pediatric Environmental Medical Record will contain the validated items required to document and presence or absence of endogenous and exogenous RF associated with PC described in the literature, as well as the main human cancerogenic agents identified by the International Agency for Research on Cancer and the US National Toxicology Program.


RESULTS
The project aims to determine the frequency of endogenous and exogenous RF associated with PC in Spain. This project will enable hypotheses to be formulated for future epidemiologic case-control and cohort studies in Spain and other European countries, thus stimulating the introduction of educational and preventive policies in the Spanish population.


CONCLUSIONS
The project requires the aid of all hospital and non-hospital pediatricians involved in pediatric cancer in informing parents and offering them the possibility of voluntarily collaborating in the "Environment and Pediatric Cancer" project by contacting the Pediatric Health Specialty Unit (Unidad de Salud Medioambiental del Hospital Infantil La Fe de Valencia [www.pehsu.org]). The collaboration of our colleagues will be essential in gaining greater insight into the RF associated with PC and in achieving prevention in the medium and long term.
