Introduction: MSC is a simple and reliable mean to diagnose hypercortisolism, yet its value to asses the outcome of treatment has rarely been addressed.Objective: Compare MSC and other classical parameters, to assess the outcome of TSS in CD.Patients and methods: Sixty-eight patients from a single Center operated for CD between 1996 and 2006. Outcome was assessed between 6–12 months post TSS. Remission was defined as: morning ...

Background: Cushing syndrome due to PPNAD is the main endocrine disorder of CNC, an autosomal dominant multiple neoplasia caused by germline inactivating mutations of the subunit type 1A (PRKAR1A) of the protein kinase A (PKA). In addition, germline inactivating mutations in the gene encoding phosphodiesterase 11A (PDE11A) have been identified in patients with PPNAD.Aim of the study: To investigate the role of PDE11A genetic alterati...

Introduction: We have previously identified (using a whole-genome large scale SNP- screening approach) germline inactivating stop codon mutations of the PDE11A4 in patients with Cushing syndrome due to micronodular adrenal hyperplasia. PDE11A4 is a cAMP/cGMP phosphodiesterase.Aim of the study: To investigate the role of PDE11A genetic alterations in a large cohort of ACT.Materials and methods: Leukocyte DNA from 117 adrenocortical ...

Recent pan-genomic analyses of tumor DNA identified specific patterns of DNA methylation –e.g. CpG islands hypermethylation in the promoter regions of genes- as pejorative prognostic markers in adrenocortical cancer (ACC). Integrated genomics clearly shows that ACC with such an hypermethylation belongs to specific subgroups of ACC with increased driver genes alterations and a poor survival.Aim: To confirm the prognostic value of this methylation pat...

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 ...
