Background: Differentiated thyroid carcinoma (DTC) survivors have an increased risk of cardiovascular mortality but, the pathophysiological mechanism remains largely unknown. Early treatment for high-risk DTC entails thyroid surgery, radioiodine therapy with thyroid hormone (TH)-withdrawal, and thyroxine suppression therapy (THST). During treatment, patients cycle from severe hypothyroidism to exogenous subclinical hyperthyroidism. TH changes in early DTC treatment might affec...

Background: A metastatic mesenteric mass is a hallmark of small intestinal neuroendocrine tumours (SI-NETs). However, little is known about the evolution of a SI-NET-associated mesenteric mass over time.Methods: Retrospectively, 530 patients with proven SI-NET and ≥2 available CT-scans were assessed for clinical characteristics at diagnosis and the presence and growth of a mesenteric mass on every consecutive CT-scan until end of follow-up or resec...

Objective: A mesenteric mass with surrounding mesenteric fibrosis (MF) is a hallmark of small intestinal neuroendocrine tumours (SI-NETs) and known to induce abdominal complications. However, little is known on the evolution over time and the pathways involved in progression. Our aim was to assess the development of the metastatic mesenteric mass over time and find predictors for progression.Methods: Retrospectively, 530 patients with proven SI-NET and &...

Background: Pancreatic Neuroendocrine Tumors (PanNETs) are highly prevalent in Multiple Endocrine Neoplasia type 1 (MEN1) and one of the main causes of mortality. Conventional imaging is the mainstay of PanNET screening/surveillance in MEN1. This study aims to assess the diagnostic accuracy of conventional pancreatic imaging studies and to determine the added value of pancreatic fine needle aspirations (FNA) for the diagnosis of MEN1-related PanNETs.Meth...
