Background: The prognosis of adrenocortical carcinomas (ACCs) is heterogeneous. Genome-wide methylation analysis of tumor DNA identified a sub-group of ACCs from the French COMETE network with CpG island hypermethylation evoking a CpG island methylator phenotype (CIMP). These ACCs are associated with a poorer prognosis (Barreau, JCEM 2013).The aim was to validate the prognostic value of CIMP in a large multicentric independent cohort from ENSAT (European...

Background: Adrenocortical cancer (ACC) is an aggressive tumour with heterogeneous prognosis. Pan-genomic studies identified molecular subgroups of ACC, remarkably associated with outcome. For routine prospective use, targeted molecular measures are needed, combined into reasonably easy and cheap techniques. The aim was to develop and validate different combinations of targeted molecular markers reflecting the molecular subgroup, and compare their prognostic value to standard ...
