Resumen:
Thanks to the initiative of the 28 molecular genetics centres, France has developed a specific structure for performing molecular analyses of tumours for all patients in France in need of it. However, the increasing number of molecular abnormalities to be screened or of tumors to be analyzed in order to guide treatments requires major technical and organisational developments. To this end, the Cancer Plan 2014-2019 advocates as a first step to implement nationwide next-generation sequencing techniques (NGS) for a limited number of genes, and then, as a second step, the conditions for comprehensive analysis of tumor genomes.
