Un programme de travail partenarial pour l’épidémiologie des cancers : bilan 2014-2019

Abstract

In France, the epidemiological surveillance of cancers is based on a multi-source surveillance system and a joint working program in partnership defined and performed by the French network of cancer registries (Francim), the Biostatistics-Bioinformatics Unit of Hospices Civils de Lyon, the French national public health agency and the French National Cancer Institute. This article presents the results of the 2014-2019 Cancer program. A questionnaire was completed for each of the 56 PTP projects, covering the implementation and financial resources committed. Among the 49 achieved projects were new estimates of incidence and survival produced at the national level for 70 types of cancer, with age-specific trends. Estimates of incidence were made at the district level for all French departments, even in districts not covered by a registry. The distribution of stage at diagnosis and social disparities in cancer incidence and survival were studied. The analysis of conditional net survival led to a better assessment of the risk of dying from cancer, which allowed improving access to insurance coverage and introducing a 'right to be forgotten' to people having a prior history of cancer. Contributing to the national and regional public policies with this innovative data, the outputs of the 2014-2019 Cancer program are successful. This makes a major contribution for the future of cancer surveillance, building on the ten-year French cancer control Strategy 2021-2030. The sustainability of registries, data protection, the crossing of databases and the implementation of a surveillance system at a geographical level lower than the district, remain challenging.
