Introduction: Osilodrostat decreases cortisol production by inhibiting 11β-hydroxylase, increasing adrenal hormones above the blockade. Here, we describe these effects of osilodrostat and associated adverse events (AEs). The efficacy and safety of osilodrostat in patients with Cushing’s disease (CD) were confirmed in the published Phase III, prospective LINC 3 study (NCT02180217).Methods: 137 patients with CD (mUFC >1.5x upper limit of norm...

Controlateral recurrence of pheochromocytoma is frequent in MEN2 patients. Cortical sparing adrenalectomy is currently recommended in this situation, but conveys a risk of adrenal insufficiency in up to 45 % of patients. The natural history of recurrent pheochromocytome is poorly known. Thus, appropriate timing of surgery and the possibility to postpone safely surgery remain debatable. We report our experience of long-term follow up of non-operated 16 pheochromocytomas in 13 M...

The characteristics of adrenal involvement in Multiple Endocrine Neoplasia type 1 (MEN1) have been defined from studies involving a limited number of patients. We have assessed retrospectively the prevalence, characteristics and evolution of adrenal involvement from the French group for the study of endocrine tumours (GTE) registry, involving 688 patients with MEN1. In our series, adrenal tumours identified at abdominal imaging occurred in 130 patients (18.9%). The mean age of...

Context: Mosaicism is a feature of several inherited tumor syndromes but is rarely systematically looked for in routine. MEN1 is an autosomal dominant hereditary syndrome characterized by several endocrine tumors affecting parathyroids, pancreas, and anterior pituitary most of the time, due to inactivating mutations in the MEN1 gene. Few cases of mosaicism in Multiple Endocrine Neoplasia type 1 (MEN1) have been described. MEN1 mosaicism is probably under-diag...

Background: Medical treatment with cortisol-lowering drugs is commonly used following pituitary surgical failure or recurrence of hypercortisolism in patients with Cushing’s disease (CD). Studies using late-night salivary cortisol (LNSF) measurement have shown persistent disruption of the circadian secretion of cortisol despite normalization of UFC in a subset of medically treated CD patients. Study aim Our objective was to assess the long-term cortisol exposure in CD pat...

Introduction: The French National Institute of Cancer (INCa) launched supported by the Ministry of Health in 2008 a program for the recognition of national networks for the management of rare cancers. Among the 23 selected networks COMETE-Cancer was recognized by INCa in 2009 for Adrenocortical carcinoma (ACC) and malignant pheochromocytoma/paraganglioma (MPP). At that time 60–120 new ACC/year and 30 new MPP/year were expected at the national level....

Introduction: Acromegaly is characterized by excessive secretion of GH and increased IGF-1 levels caused by benign pituitary adenoma. The ACRO-POLIS study describes symptoms and comorbidities of acromegaly at diagnosis in a large cohort of patients diagnosed between 2009 and 2014 in France.Methodology: Observational, cross-sectional, multicentre study included adult patients with acromegaly diagnosed for less than 5 years. Data were collected retrospecti...

Introduction: Acromegaly is characterised by chronic, excessive secretion of GH and increased IGF1 levels caused by benign pituitary adenoma. This study aimed at describing the symptoms and comorbidities of acromegaly at diagnosis, in a large cohort of patients diagnosed between 2009 and 2014.Methods: Observational, cross-sectional, multicentre study conducted in France between September 2013 and June 2014. Adult patients with acromegaly diagnosed for &#...

The loss of nychthemeral rhythm is a feature of endogenous hypercorticism that may be investigated by the assay of midnight salivary cortisol (serC0h) although often replaced by serum cortisol assay. However, manufacturers of cortisol immunoassays kits seldom provide reference values for this horary. We present here tentative reference values of serC0h with an automated imunoanalyzer (DXi800, Beckman Coulter).The population retrospe...

Introduction: CD is a rare disease. Our aim was to describe demographic and clinical characteristics together with initial management of patients with CD.Patients and methods: A retrospective analysis of 437 CD patients diagnosed between 1996 and 2009, followed in 5 tertiary centers (Bordeaux, Grenoble, Lyon, Marseille, Paris) was performed in the frame of the national program for rare diseases.Results: 347 (80%) were women. Mean a...
