Objective: To analyze long-term treatment outcomes and to determine prognostic factors affecting the survival of patients with ECS. Matherials and methods: Retrospective, observational study on 147 patients (88 women, 59 men) with ECS diagnosed between 1990 and 2021. Various imaging studies were performed on all patients to find the source of ACTH producing neuroendocrine tumor (NET). Multivariable analysis was performed using a Cox proportional hazards ...

Introduction: Regardless of improvements in MRI, up to 20% of ACTH-secreting pituitary tumors are only identified at surgical exploration. The objective was to estimate whether there is any difference in blood vessels and the subsequent ability to uptake contrast agent in visualized micro-adenomas as compared to non-visualized on MRI ACTH-secreting pituitary tumors.Materials and methods: Retrospective evaluation of ACTH-positive pituitary tumors from pat...

BackgroundEctopic ACTH syndrome (EAS) is a rare cause of endogenous hypercortisolism.ObjectiveTo analyze clinical, biochemical features and treatment outcomes of patients with EAS.Materials and methodsRetrospective, observational study on 129 patients (79 women, 50 men) with EAS diagnosed between 1990 and 2020. Plasma levels of ACTH (reference range: morning 7.2&#...

Introduction: Corticotropinomas constitute up to 45% of aggressive pituitary tumors, which characterized by rapid and invasive growth, a high Ki-67 index, resistance to conventional treatments and recurrence in 15-20% of the cases. Progression of corticotroph tumor after bilateral adrenalectomy or Nelson’s syndrome is a frequent severe complication and may present with aggressive tumor behavior.Clinical case: A Cushing disease was diagnosed in a wom...

Objective: To estimate the outcome of neurosurgery in patients with Cushing’s disease (CD) with and without pituitary adenoma visualisation on MRI.Material and methods: Patients with confirmed CD (11.2008–11.2014) by both inferior petrosal sinus sampling (IPSS) and histological evaluation after neurosurgery were enrolled into the study. Subjects were referred for IPSS because of non-visualised pituitary adenoma or contradictory results of non-i...

According to previous research microRNA (miR) are expressed differently in corticotropinoma and ACTH-secreting neuroendocrine tumors. MiR are released into circulation by several mechanisms and considered to be promising biomarkers.Objective: To evaluate whether preselected miR are differently expressed in plasma samples of patients with ACTH-dependent Cushing’s syndrome (CS).Materials and methods: The blood samples were colle...

Introduction: Recent studies have shown that microRNA could serve as biomarkers in various types of cancer and other diseases. Aim: To reveal microRNA that differ in patients with Cushing’s diseases (CD) and Ectopic ACTH-syndrome (EAS) to form a specific panel for differential diagnosis of ACTH-dependent Cushing’s syndrome (CS).Materials and Methods: Plasma samples from both sinuses and cubital vein were drained during in...
