Background: A recent study of a small series of patients with appendiceal neuroendocrine tumors (ANETs) fulfilling various criteria for right hemicolectomy (RHC) revealed that ≈ 25% may harbor identifiable extra-appendiceal disease. The residual disease might not have been detected using the latest European Neuroendocrine Tumors Society (ENETs) revised pathological criteria.Aims: To evaluate the latest pathological criteria for completion right hem...

Purpose: The efficacy and safety of RAD, an mTOR inhibitor, in patients with well differentiated metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NET).Material and methods: We studied seven male patients (mean age 55 years, range 36–75) with well differentiated non functioning stage IV GEP-NETs (five pancreatic, one hindgut carcinoid, and one NET of unknown primary). All received RAD 10 mg/day in combination with long acting octerotide 3...

Background: The exact indications and/or the type of operation requiring for the treatment of gastric carcinoids (GC) type 1, are not clearly stated. The present study was designed to evaluate the value of the oncological gastrectomy in the treatment of GC type 1.Materials and method: Between January 2004 and December 2010, we advocated gastric resection in cases of GC type 1 when at least one of the following criteria was present: i) multiple recurrent ...

Background: Incidentally discovered adrenal adenomas (AA) are associated with increased prevalence of hypertension, obesity, and impaired glucose tolerance, all established risk factors for cardiovascular (CV) morbidity. However, most studies were performed in patients with AA and autonomous cortsisol and/or aldosterone secretion, whereas the presence of cardiovascular risk in patients with non-secreting AA has not been looked into detail.Methods: Cardio...

Objectives: To characterize the possible role of the osteoprotegerin (OPG) and receptor activator of NF-κB ligand (RANKL) system in thalassemia-related bone loss.Background: Osteoporosis represents an important cause of morbidity in patients with β-thalassemia major and its aetiology is multifactorial.Methods: Serum concentrations of OPG, RANKL, markers of bone turnover and lumbar spine bone mineral density (BMD) were mea...

PurposeThere is a continuity of changes ranging from enterochromaffin‐like (ECL) cell hyperplasia to type 1 gastric neuroendocrine neoplasms (GNEN1) with important clinical implications. Although the effect of the circadian clock system on tumorigenesis has been addressed, the role of the peripheral clock system in the transition from ECL-cell hyperplasia to GNEN1 remains to be explored.MethodsSix patie...

Introduction: Gastric neuroendocrine tumors (GNET) are rare gastric neoplasms which are developed due to hypergastrinemia and enterochromaffin-like (ECL) cell hyperplasia. Although the effect of the circadian clock system disruption on tumorigenesis has been already studied in various malignancies and autoimmune diseases, the role of the peripheral clock system in the transition from ECL-cell hyperplasia to GNEN1 (Type 1 Gastric Neuroendocrine Neoplasms) remains unexplored.</p...

Introduction: The biological rhythm pattern is synchronized through circadian oscillation of cortisol and melatonin release. Increased cortisol levels and circadian rhythm disruption act as an oncogenic factor in endometrial cancer through among others- dysregulation of cell proliferation/apoptosis and invasion.Aim: To investigate, whether there is an oscillatory expression of the clock genes, MT1 and GR expression in human endometrial carcinoma cells. T...

Introduction: Adrenal incidentalomas (AI) with or without concomitant autonomous cortisol secretion can be associated with several metabolic alterations that may lead to increased cardiovascular risk. However, data regarding insulin resistance (IR) during long term follow-up of AI are scarce. The aim was to prospectively investigate the presence and evolution of IR in patients with AI between 2003 and 2014.Methods: Seventy three patients with AI for at l...

Introduction: Insulin-like growth factor-I (IGF-I) has a role in cell proliferation, differentiation, migration, and survival. By alternative splicing different IGF-I mRNA transcripts as IGF-IEc (mechano growth factor, MGF) or IGF-IEa variants are produced. MGF induces muscle hypertrophy and implicated in the pathophysiology of various types of cancer. Aim of the study was to investigate the role of MGF in the pathophysiology of neuroendocrine neoplasms (NENs).<p class="ab...
