Objective: Cushing disease (CD) is a rare entity caused by ACTH-secreting pituitary tumors, leading to prolonged hypercortisolism. Most cases are sporadic but can rarely occur in the context of familial predisposition, due to germline mutations in genes such as MEN1, leading to multiple endocrine neoplasia type 1, MEN1. We have reported previously that CD can be the first and only presenting manifestation of MEN1. Read More

This review focuses on discussing the main modifications of the recently published 2017 WHO Classification of Neoplasms of the Neuroendocrine Pancreas (panNEN). Recent updates separate pancreatic neuroendocrine tumors into 2 broad categories: well-differentiated pancreatic neuroendocrine tumors (panNET) and poorly differentiated pancreatic neuroendocrine carcinoma (panNEC), and incorporates a new subcategory of "well-differentiated high-grade NET (G3)" to the well-differentiated NET category. This new classification algorithm aims to improve the prediction of clinical outcomes and survival and help clinicians select better therapeutic strategies for patient care and management. Read More

Multiple endocrine neoplasia type 1 is a rare genetic syndrome, characterized by the co-occurrence, in the same individual or in related individuals of the same family, of hyperparathyroidism, duodenopancraetic neuroendocrine tumors, pituitary adenomas, adrenocortical tumors, and neuroendocrine tumors (carcinoids) in the thymus, the bronchi, or the stomach. Multiple endocrine neoplastic type 2 is a rare genetic syndrome, characterized by the familial occurrence of medullary thyroid carcinoma either isolated or associated with pheochromocytoma, primary hyperparathyroidism, or typical features (Marfanoid habitus, mucosal neuromas). Subjects with clinical MEN1 and those who carry a mutation in the MEN1 gene should be offered biochemical and imaging screening in order to detect tumors and evaluate their progression over time.

Multiple endocrine neoplasia type 1 (MEN1) is associated with a heterozygous inherited mutation of the menin 1 () gene; however, the molecular pathogenesis remains to be fully elucidated. In the present study, whole exome sequencing was performed on two pancreatic neuroendocrine tumors (PNETs), termed T1 and T2, peri-tumoral tissue (PT) and a blood sample obtained from a patient with MEN1. The cells in T1 and T2, but not PT, showed loss of chromosome 11 where was located, confirming that the loss of heterozygosity (LOH) of was a crucial event in tumorigenesis. Read More

Epigenetic regulation is emerging as a key feature in the molecular characteristics of various human diseases. Epigenetic aberrations can occur from mutations in genes associated with epigenetic regulation, improper deposition, removal or reading of histone modifications, DNA methylation/demethylation and impaired non-coding RNA interactions in chromatin. Menin, the protein product of the gene causative for the multiple endocrine neoplasia type 1 (MEN1) syndrome, interacts with chromatin-associated protein complexes and also regulates some non-coding RNAs, thus participating in epigenetic control mechanisms.

Despite prognostic grading and staging systems, it is a challenge to predict outcomes for patients with pancreatic neuroendocrine tumors (PanNETs). Sequencing studies of PanNETs have identified alterations in death domain-associated protein (DAXX) and alpha-thalassemia/mental retardation X-linked chromatin remodeler (ATRX). In tumors, mutations in DAXX or ATRX and corresponding loss of protein expression correlate with shorter times of disease-free survival and disease-specific survival of patients. Read More

Generally, pancreatic polypeptide-secreting tumor of the distal pancreas (PPoma) is classified as a rare tumor, and may occur sporadically or be associated in families or with multiple endocrine neoplasia type 1 (NEM 1). It grows slowly, reaching large dimensions at the time of diagnosis and the symptomatology is fundamentally due to the mass effect, causing either non-specific abdominal pain or symptoms suggestive of obstruction of the pancreatic or biliary duct. Therefore, when detected, they are usually malignant, with metastases mainly in the liver. Read More

Multiple endocrine neoplasia type 1 (MEN1) is a rare hereditary tumoral syndrome, featured by a combination of neoplasms of various endocrine and nonendocrine tissues. Approximately 33% of MEN1-related deaths are due to the malignant behaviour of well-differentiated neuroendocrine tumors (NETs), for which a preventive surgical treatment is not feasible. Somatostatin analogues (SSA) have been employed in the treatment of NETs in the stage of advanced or metastatic disease, in order to control the growth and secretion of tumor lesions. Read More

Neuroendocrine tumours of the lung comprise low [typical carcinoid (TC)], intermediate [atypical carcinoid (AC)] and high-grade [small-cell lung cancer (SCLC) and large-cell neuroendocrine carcinoma (LCNEC)] malignancies, while a pre-invasive lesion [diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH)] may generate a subset of peripheral carcinoid tumours. These neoplasms are differentiated conventionally based on mitotic rate, presence of necrosis and cytological details, according to the 2015 World Health Organisation (WHO) classification. Clinical data and molecular alterations distinguish carcinoids and high-grade carcinomas into two separate categories. Read More
