#4218 Primary hepatic neuroendocrine tumor in a series of 8 cases

Introduction: Primary neuroendocrine (NET) tumors of the liver are extremely rare, accounting for 0.3% of all NETs; unlike metastatic neuroendocrine tumors, rarely cause carcinoid syndrome. Edmonson reported the first case in 1958. Since then, fewer than 150 cases have been reported in the literature. Before making the diagnosis of primary hepatic neuroendocrine tumor it is imperative to explore the patients, several radiological investigations can help to pinpoint the primary which is most often digestive.

#3945 8-year follow-up reveals therapeutic approaches for patients with neuroendocrine neoplasms – Findings from the TNE West Network: 2016-2023

Introduction: Neuroendocrine tumors (NETs) are relatively rare and often diagnosed late, typically occurring between the ages of 40 and 60. They primarily manifest in the gastrointestinal system, pancreas, bronchi, lungs, thymus, and thyroid.

#3773 Pancreatic neuroendocrine tumors in Oran – Epidemiological, histological and therapeutic aspects

Introduction: Pancreatic neuroendocrine tumors (pNET) are rare, they represent third of digestive NETs. Their incidence is increasing with a rate that has been multiplied by 5 over the past 20 years to reach 0.6 cases/100,000. This increase is probably related to better detection of this type of tumor. The discovery is often fortuitous or following a non-specific symptomatology which depends on the seat of the tumor. They are often the cause of mainly hepatic metastases. Only surgery at an early stage allows a good evolution. Few data are available on pNETs in our country.

#3771 Epidemiological profile and survival of neuroendocrine tumors of the ampulla of Vater

Introduction: Duodenal neuroendocrine tumors are rare, they represent nearly 2% of digestive NETs. Their incidence is increasing due to better detection. The diagnosis is often late because of the non-specific symptomatology of the tumor. The 5-year survival of duodenal NETs is 68% when the tumor is diagnosed at an early stage.

#3769 Adrenal neuroendocrine tumors in Oran – Epidemiology and survival

Introduction: Pheochromocytomas (PCC) are rare neuroendocrine tumors with a prevalence of 1/10000 in the general population. They are sporadic in 80% of cases, family forms are found in 10 to 20% of cases. PCCs represent 60% of multiple endocrine neoplasia type 2. They occur at any age with a peak between 30 and 50 years old. The clinical symptomatology dominated by arterial hypertension is linked to the hypersecretion of catecholamines. Metastases are common in the liver, bone or lung. The 5-year survival of malignant pheochromocytomas is less than 50%.
