Neuroendocrine tumors (NETs) are a group of malignancies that originated from neuroendocrine cells, with the most common sites being lungs and the gastrointestinal tract. Lung NETs comprise 25% of all lung malignancies. Small cell lung cancer is the most common form of lung NETs, and other rare forms include well-differentiated typical carcinoids (TCs) and poorly differentiated atypical carcinoids (ACs). Read More

Neuroendocrine carcinoma of esophagus represents less than 2% of cases of cancer of the esophagus. This presentation is extremely unusual, as this type of carcinoma typically presents with greater frequency in bronchopulmonary regions. The symptoms are usually associated with esophageal obstruction and include odynophagia, dysphagia and weight loss and are not usually associated with Carcinoid syndrome. Read More

Purpose: Octreotide SC depot is a novel, ready-to-use formulation administered via a thin needle. In a phase 1 study in healthy volunteers, this formulation provided higher bioavailability of octreotide with faster onset and stronger suppression of IGF-1 in healthy volunteers versus long-acting intramuscular (IM) octreotide. This phase 2 study evaluated the pharmacokinetics, efficacy, and safety of octreotide SC depot in patients with acromegaly and functioning NETs, previously treated with octreotide IM. Read More

It is uncertain whether thymic neuroendocrine tumors (NET) associated with Cushing's syndrome (CS) produce corticotropin-releasing hormone (CRH) and adrenocorticotropin hormone (ACTH) and whether the thymus contains ACTH and/or CRH cells that could originate NET. The clinicopathologic features of 5 typical (TC) and 6 atypical carcinoids (ATC), 10 additional non-neoplastic thymi, 6 adrenal glands with bilateral nodular hyperplasia and 8 adrenal cortical adenomas were reviewed. Representative slides were immunostained for ACTH and CRH. Read More

The clinicopathological features of lung neuroendocrine neoplasms (NEN) with a high proliferative index at the border area between atypical carcinoid and neuroendocrine carcinoma, have not been investigated so far. The aim of this study was, therefore, to search for lung NENs, which are well-differentiated but show Ki67 values that overlap with those of poorly differentiated NENs (PD-NENs). Resected lung NENs from 244 Japanese patients were reviewed and Ki67 index was assessed in all tumors. Read More
