#2819 Occurrence of Pancreatic Exocrine Insufficiency in Patients with Advanced Neuroendocrine Tumours Treated with Somatostatin Analogue

Introduction: Neuroendocrine neoplasia (NENs) are heterogeneous tumours caracterized by a relatively indolent rate of growth. Usually, in G1 and G2 GEP-NENs, first-line therapy is SSAs, considering their efficacy, good safety profile, and antiproliferative effects. SSA treatment inhibits the production and excretion of pancreatic enzymes and PEI is known to be an adverse effect of SSA treatment.

#2212 A Rare Case of Paraneoplastic Hypercalcemia Secondary to a Neuroendocrine Pancreatic Tumour (pNET).

Introduction: Paraneoplastic hypercalcemia (HC) is a well-described affection in literature. It can relay on several mechanisms among with bone osteolysis, Parathormone (PTH) related peptide (rp) production, primary hyperparathyroidism, and Calcitriol (CT) secretion. CT secretion-mediated HC is more frequently observed among lymphomas and has only been once reported in pNET.

#2176 New MENIN Mutation Associated with Familial Isolated Hyperparathyroidism. Clinical Case of Three Young Sisters.

Introduction: The primary hyperparathyroidism (PHPT) is a sporadic disorder in the majority of cases, and only 5-10% of cases are associated with familial syndromes. The following familial syndromes associated with PHPT are known to date: multiple endocrine neoplasia type 1 (MEN1), type 2A (MEN2A), type 4 (MEN4), hyperparathyroidism-jaw tumor syndrome (HPT-JT), familial hypocalciuric hypercalcemia (FHH), neonatal severe hyperparathyroidism (NSHPT) and familial isolated hyperparathyroidism (FIHP). FIHP is defined as hereditary PHPT without the association with other diseases or tumors and may be caused by mutations in MEN1, HRPT2, or CASR genes.
