Background: Pheochromocytomas are rare tumors, with prevalence less than 0.2% of hypertensive patients, in general population being unknown. With increasing access to imaging and hormonal workup, more pheochromocytomas are diagnosed. This may have changed the occurrence of the classic presentation with hypertension and the classic triad.Methods: We present 3 cases of pheochromocytoma diagnosed in our departments over the last 2 years, with 3 different ph...

Introduction: Epidemiological and clinical studies have proven direct correlations between chronic stress, inflammation and cancer progression. The inflammatory environment preexisting the malignant change and elevated IGF-1 levels are associated with higher cancer risk, especially through GH effects on cell proliferation and inhibition of apoptosis.Aim: To evaluate the relationship between biological and hormonal stress markers, growth factors and breas...

Introduction: Obesity and insulin resistance have been identified as risk factors for breast cancer and are associated with late-stage diagnosis and poor prognosis. Ghrelin is a unique gut-derived peptide that has major impact in energy homeostasis and weight regulation, with new emerging implications in tumorigenesis process, especially in hormone-dependent cancers.Aim: To evaluate the relationship between ghrelin, clinico-biological parameters of obesi...

Objectives: Radiation induces DNA double strand breaks (DSBs) that can be visualized and enumerated as microscopic γ-H2AX and 53BP1 foci. This study analysed the dose- and time-dependency of the DNA damage in blood lymphocytes in patients after a personalised high-activity 177Lu-DOTATATE treatment.Methods: We investigated multiple blood samples of three patients up to 96 h after personalised high-activity peptide receptor radionuclid...

Introduction: Adrenal glands are common sites for secondary lesions derived from malignant tumours (lymphoma, melanoma, renal, breast, colon, and bronchopulmonary cancer). Patients with adrenal secondary lesions are typically asymptomatic but 1% may present with adrenal insufficiency as a first manifestation. We report the cases of two males with lung adenocarcinoma, first presented with acute adrenal insufficiency.Cases presentation: Case 1: LC, 65 year...

Introduction: Breast neuroendocrine carcinoma is a rare aggressive neuroendocrine tumour (NET) and the research on this subject is poor. Only seven studies were cited in the literature. Incidence in the population has not been reported, but the prevalence is under 0.1% of all breast carcinomas.Case report: AV, 72, is hospitalised for bone pain and significant weight loss (15 kg in 2 months). Patient’s previous history are: diabetes, hypertension, no...

Pancreatic neuroendocrine tumors (pNET) represent 1.3% of pancreatic tumours, ~65% patients presenting with metastatic/unresectable disease. Clinically, pNET may be asymptomatic, accompanied by carcinoid syndrome or abdominal pain.Patient N.A. aged 73, with a history of hemorrhagic pancreatitis, was diagnosed in 2003 with a hyperechoic heterogeneous solid pancreatic tumour of 28/28 mm. No therapy/monitoring were proposed. After 7 years of asymptomatic ev...

Background: GEP-NETS and PPGLs in pediatric patients are rare; however, recognition of these diseases has increased recently. 10–20% of pediatric patients with GEP-NETs and up to 47% of pediatric patients with PPGLs present with metastatic disease at diagnosis. The disease is often unresectable with poor prognosis, and very few non-surgical therapies are approved for these patients. Due to paucity of data surrounding treatments for pediatric patients with advanced GEP-NET...

Context: Endogenous Cushing’s syndrome (CS) may have different effects in children than what has been described in adults. Prior studies of children and adolescents with CS have identified cognitive decline despite reversal of brain atrophy after remission of CS, as well as residual impairment in quality of life measures. Although the observations of parents of children and adolescents with CS support personality changes, significant psychopathology has not been described...

Background: The rapid advancements in the field of allogenic hematopoietic stem cell transplantation (allo-HSCT) and better management of acute postprocedural complications have led to increased life expectancy, but at the same time to higher incidences of long-term complications. Conditioning regimens (chemotherapy, total body irradiation), immunosuppresive treatments and immune dysregulation threaten endocrine and metabolic functions, leading to late effects, including hypog...
