The Methodological Platform for studying social inequalities

This Platform is an example of the work done by CNO to develop innovative tools in France. Research unit UMR 1086 on "Cancer and Prevention", led by Prof. Guy Launoy in Caen, developed tools for the purposes of its own research (definition of geographical entities, geocoding of patients, testing an aggregated national social deprivation index) which are highly suited to promoting research into social and geographical inequalities in oncology. With the help of its strong links with the FRANCIM network, it was able to conduct the first study in France to assess the impact of social deprivation (attributable risk) on cancer incidence. CNO was quick to realise the benefits of making these skills available to a national audience, knowing that there would be many potential users: cancer registries, certified research teams, clinical research centres, regional health observatories, regional health authorities, the Institute for Public Health Surveillance (INVS) and the National Cancer Institute (INCa). In 2012, CNO presented its plans to INCa and then to the Confe-rence of Cancéropôles. The objective was to set up a national tool that could be used for measuring social inequalities in health. It came out in the discussions that both Cancéropôle Grand Sud-Ouest (GSO) and Cancéropôle Ile-de-France (IDF) possessed methodological analysis expertise that could enhance the tool. This innovative tool became a nationwide platform with funding from The national anti-cancer league at the end of 2012 and now brings together the methodological and interventional skills acquired by research teams from the three cancer hubs: CNO (U 1086 research unit "Cancer and Prevention", Caen), GSO (IFERISS [FR4142], Toulouse) and IDF (U 1018 INSERM research unit "Cancer Epidemiology", Villejuif). A four-year European project conducted under the “COST” program by Guy Launoy is now develop-ping a social deprivation index in 13 European countries (France, UK, Portugal, Spain, Italy, Germany, Belgium, Denmark, Finland, Luxembourg, Slovenia, Czech Republic, Switzerland), using a single source of data (EU-SILC) and a single development me-thodology. This will make it possible to carry out European level comparative studies.
