ARECEA manages the French National Registry of Childhood Solid Tumors (RNTSE). RNTSE and RNHE (French National registry of Childhood Haematopoietic malignancies) jointly ensure the surveillance of cancer in children aged less than 18 years (up to 15 years until 2010) in France. These two registries receive national public funding. The RNHE specifically records haematological malignancies while the RNTSE records malignant solid tumours, including benign tumours of the central nervous system.
The two registries generate the statistics for all of France on incidence and survival for all childhood cancer types and develop descriptive studies on the spatiotemporal variations in incidence. They also serve as a support for etiologic research on risk factors for childhood cancers.
Dr Brigitte Lacour, Principal Investigator, is a hospital practitioner, doctor of medicine, and specialist in public health. She has directed the National Registry for Childhood Solid Tumours in Nancy since 2000, after having headed the Lorraine Registry of Childhood Cancer. She is a member of the Scientific Board of ACCIS, a European database on childhood and adolescent cancers coordinated by the International Center for Research on Cancer, and is a member of the Bureau of the French Network of Cancer Registries (FRANCIM).
Dr Martine Hours is PhD in epidemiology, specializing in occupational and environmental exposures. She assured in the past the coordination of the French part of the INTERPHONE study and she takes part to the scientific coordination of the Mobi-kids study in connection with Dr Brigitte Lacour.
Thomas Rémen, Fieldwork coordinator, is PhD in epidemiology and public health. His main research focus is environmental health. He coordinates the Mobi-kids study in the 7 areas in France.

Brief background of study:
Recruitment took place in all regions in March 2011 except in Strasbourg and Bordeaux where it began in September 2012. Cases inclusion ended December 31th, 2014 excepted in Gironde (June 30th, 2014) and in Hérault (September 30th, 2014). Cases and controls interviews go on until March 31th, 2015 (September 30th and December 31th 2014 for the two others areas). To date we recruited 103 cases and 169 controls.
This project received funds from the European Community (FP7/2007-2013) and in France from the French National Agency for Sanitary Safety of Food (ANSES, contract FSRF 2008-3), French National Cancer Institute (INCa), Pfizer Fondation and League against cancer.
How did your centre become involved in MOBI-Kids?
Dr Martine Hours coordinated the Interphone study. As Mobi-kids study applied to children and adolescents, the National Registry of Childhood Solid Tumors (RNTSE) was more appropriate to coordinate the study.
Are you involved with more than fieldwork?
Our centre has participated to Mobi-Expo study (with 65 volunteers) whose objective is to characterize the use of mobile phones in young people and improve the assessment of radiofrequency exposure in the main Mobi-Kids study.
What are your research interests (beyond MOBI-Kids)?
Dr. Lacour focuses on childhood cancer registration and descriptive epidemiology specifically in children solid tumours. She is also interested in etiological studies, since she belongs to the INSERM team UMR-S 1113, EPICEA. In this context, she also contributes to set up the Cohort of the national pediatric registry which ensures the follow-up of all cases included in the national childhood cancer registries since 2000. The aim is to know the health status f childhood cancer survivors and to study the long term iatrogenic effects.
Why do you think MOBI-Kids is an important study?
MOBI-KIDS study is a unique study by its international scope and its optimum power conditions with around 1000 cases and 2000 controls going to be included.
What do you think is the most interesting part about MOBI-Kids?
The collaboration with worldwide research teams is very interesting and fruitful. Besides it was a challenge for each team to conduct this complex study including both children and young adults with a serious but rare disease requiring collaboration with many hospital services.
