Introduction: The steroidogenesis inhibitors ketoconazole and metyrapone are frequently used for treatment of Cushing’s syndrome, but can cause side effects. LCI699 is a known 11β-hydroxylase inhibitor, but effects on other steroidogenic enzymes are unknown. We aimed to compare effects of LCI699, ketoconazole, and metyrapone in vitro.Methods: HAC-15 cells, with or without 10 nM ACTH, and three primary human adrenocortical adenoma cultu...

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...

Background: Adrenocortical carcinoma (ACC) is a rare but devastating malignancy (5-year survival 18–57%), with limited treatment options. Currently, mitotane is the first-line medical treatment for metastatic ACC and is used in the adjuvant setting after surgery to prevent recurrence. Mitotane is an adrenolytic drug that is thought to act by disruption of mitochondria with subsequent activation of apoptosis. However, mitotane treatment comes with many drawbacks, such as s...

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 &...
