Background: Primary hyperaldosteronism (PHA) is the most frequent type of endocrine hypertension with a prevalence that is continuously rising. Following the introduction of diagnostic tests that consider both the adrenocorticotropic hormone effect andrenin–angiotensin–aldosterone system (RAAS), the post-dexamethasone saline infusion test (D-SIT) and the overnight dexamethasone, captopril, valsartan test (DCVT) using pharmaceutical RAAS blockade, a higher prevalenc...

Expression of estrogen-related receptors and epidermal growth factor receptor in normal adrenal cortex and adrenocortical tumors: A possible role of GPR30 and EGFR in adrenocortical malignancy

Introduction: The majority of adrenal neoplasms are benign while adrenocortical carcinomas (ACC) are rare with poor prognosis. Previous studies indicated that estrogens play important role in the etiology and progression of adrenocortical tumors. Estrogens exert genomic activities trough the estrogen-receptor (ER) subtypes α and β, while the non-genomic effects are mediated by membrane-bound-G-protein-coupled-ER-30 (GPR30). Although estrogens induce cancer cell ...

The role of Chchd2 protein in adrenal tumorigenesis

BackgroundRecent data have shown the anti-apoptotic effect of Chchd2 mitochondrial protein through the Bcl-2/Bax pathway in various cancers. Bax is regulated primarily by proteins-members of Bcl-2 family and mainly the Bcl-2 protein, which has been found to prevent Bax from accumulating in mitochondria. In response to apoptotic stimuli, Chchd2 decreases and loses its mitochondria localization accompanying by decreased Bcl-2/Bax interaction and increased ...

Prognostic factors in Adrenocortical Carcinoma: A single institution case-series

Parianos Christos , Kyriakopoulos Georgios , Kostakis Ioannis D. , Nasiri-Ansari Narjes , Aggeli Chrysanthi , Angelousi Anna , Choreftaki Theodosia , Papavassiliou Athanasios G. , Kaltsas Gregory , Zografos Giorgos , Kassi Evanthia

BackgroundAdrenocortical carcinoma (ACC) is a rare but very aggressive endocrine malignancy with poor survival. Histopathology is important for diagnosis, while in some cases immunohistochemical markers and gene profiling of the resected tumor may be superior to current staging systems to determine prognosis.AimHerein, we aimed to present the 20year experience at a tertiary Hospital in patients with ACCs and ...

Pre-, peri- and post-operative characteristics of biochemically silent pheochromocytomas: a case series

Introduction: Pheochromocytomas (PCs) and paragangliomas are rare tumours occurring in about 0.6 cases per 100,000 person-years. Biochemically silent PCs with normal catecholamine levels due to lack of catecholamine secretion or subtle secretion within the established normal levels are even rarer. Up to date, biochemically silent PCs are poorly investigated.Aim: To assess the pre-, peri- and post-operative characteristics of patients with biochemically s...
