Adrenal neuroendocrine tumors in Oran – Epidemiology and survival

#3769

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%.

Aim(s): Describe the epidemiological profile and estimate the 1-year survival of patients with adrenal neuroendocrine tumor.

Materials and methods: Data were obtained from two years of recording as part of monitoring by the hospital cancer registry of the Hospital and University Establishment of the wilaya of Oran (Algeria). The central coding is carried out using the CIMO2 and CIM10 supports.
