Primary liver neuroendocrine tumors (PLNETs) are rare tumors of the liver. They share some common characteristics with neuroendocrine tumors (NETs) of the extrahepatic bile ducts, such as slow rise, hormonal, and histological features. Nevertheless, they possess some peculiarities and the major feature is the difference in the metastatic potential between PLNETs and NETs. PLNETs have less metastatic potential compared with NETs, which is the main factor based on which differential diagnosis between the two groups is achieved...

PURPOSE: The molecular underpinnings that may prognosticate survival and increase our understanding of tumor development and progression are still poorly understood. This study aimed to define the molecular signatures for malignancy in small cell lung carcinoma (SCLC), which is known for its highly aggressive clinical features and poor prognosis. EXPERIMENTAL DESIGN: Using clinical specimens, we performed a comparative proteomic analysis of high-grade SCLCs and low-grade pulmonary carcinoid tumors (PCTs), both of which are types of neuroendocrine tumors...

Neuroendocrine tumors (NETs) are rare neoplasms, which represent complex challenges in diagnosis and treatment. Even in the metastatic stage there are important differences in the type of tumor in comparison to gastrointestinal and pancreatic adenocarcinomas. Therefore, the disease courses are substantially different depending on the grade of differentiation. Even in the metastatic stage the 5‑year survival rates of G1 tumors is up to 83%. Approximately 20% of small intestine NETs additionally show hormone activity, which can compromise survival and the quality of life...

Context Air space invasion or aerogenous spread of lung adenocarcinoma is a relatively new concept and has been implicated as a potential prognostic factor as well as has been added as an exclusion point in the diagnosis of minimally invasive adenocarcinoma. Potential role for Ki-67 immunostaining as diagnostic and prognostic marker in pulmonary carcinoid tumors has been suggested in the literature, given the significant interobserver variability and the difficulty in predicting their clinical behavior. Objective To review the concept of air space invasion in lung adenocarcinoma and the current controversies regarding the role of Ki-67 immunostaining on pulmonary carcinoid tumors Data Sources PubMed search of English literature...

Lung well-to-moderately differentiated neuroendocrine tumors (also known as carcinoids) and large cell neuroendocrine lung carcinoma (poorly differentiated neuroendocrine tumor) are rare neuroendocrine neoplasms, which account for less than 4% of all lung neoplasms. Due to their low incidence, their systemic treatment is greatly influenced by therapeutic evidence derived from the more frequent gastroenteropancreatic neuroendocrine neoplasms and/or small cell lung carcinoma leading to significant bias. Currently, employed systemic therapies for lung carcinoids, aiming at controlling tumor growth include long acting somatostatin analogues (SSAs), peptide receptor radionuclide therapy, chemotherapy and molecular-targeted therapy...

A 56-year-old man who was recently diagnosed with a carcinoid tumor of the os petrosum was referred for a Ga-DOTA-TOC PET/CT scan. Besides the moderately increased Ga-DOTA-TOC accumulation in the carcinoid tumor, the scan showed strongly increased and focal Ga-DOTA-TOC uptake in an additional lesion in the right parotid gland. The markedly different Ga-DOTA-TOC avidity suggested a different etiology, and histological examination demonstrated a pleomorphic adenoma.

BACKGROUND AND OBJECTIVE: BLyS (B-Lymphocyte stimulator) is over-expressed in several tumoral settings, with direct or indirect effects on neoplastic proliferation and possibly representing a therapeutic target. In this study we explored the role of BLyS in a large population of patients with neuroendocrine tumors (NETs). METHODS: The study analyzed the stored sera of 124 consecutive unselected patients with NETs: 36 lung carcinoids (24 typical, 12 atypical), 47 gastroenteric tract and 41 pancreatic (30 non-functioning and 11 functioning: 9 insulinomas, 2 glucagonomas)...

Although Ki-67 labeling index (Ki-67%) is not a diagnostic or grading criterion in the World Health Organization classification of pulmonary carcinoid tumor, oncologists often request this test. A survey was administered at a North American Society for Neuroendocrine Tumors meeting to understand how Ki-67% is used in oncologic practices. A systematic literature review was performed to gather best evidence regarding the use of Ki-67%. Consecutive pulmonary carcinoids were stratified into pulmonary typical carcinoids with Ki-67% <5% (group A, n = 187), typical carcinoids with Ki-67% ≥5% (group B, n = 38) and atypical carcinoids irrespective of Ki-67% (group C, n = 31)...

CONTEXT: The 68 Ga-labelled somatostatin analogues (68 Ga-DOTA-SSAs) is becoming popular as an important diagnostic tool in neuroendocrine tumors as evidenced by a growing number of reports detailing institutional experience with various DOTA peptides. However, only few prospective studies have compared 68 Ga-DOTA-SSAs and somatostatin receptor scintigraphy (SRS) in gastroenteropancreatic neuroendocrine tumors (GEP-NETs) and pulmonary neuroendocrine tumors. OBJECTIVE: The aim of our prospective study was to perform head-to-head comparison between 68 Ga-DOTATATE PET/CT and standard imaging work-up (SI) that included multiphasic CT, liver MRI, and SRS using single photon emission computed tomography...

We report a case in which a radial arterial line was placed prior to induction of general anaesthesia in a 76 year old male with prostate cancer and multiple co-morbidities who presented for thoracoscopic resection of a right lower lobe carcinoid lung tumor. The patient's intra-operative course was complicated by acute blood loss requiring conversion to an open procedure. A subsequent injury to the superior vena cava resulted in the need for immediate re-exploration at the conclusion of surgery. While the arterial line was still indicated in this patient's postoperative course in the ICU, malfunction on post-operative day one resulted in removal of the catheter...

Bronchial carcinoids (BC) are indolent neuroendocrine tumors (NET) that are classified as malignant because they can locally infiltrate and metastasize. Resection is the primary treatment for most localized carcinoid tumors, with lung parenchymal-sparing surgery the favoured objective for patients with central airway tumors. Sleeve bronchoplasty techniques are complex surgical procedures defined as parenchyma-saving because they allow a radical resection with tumor-free margins while preserving the maximum amount of parenchyma...

OBJECTIVE: To investigate clinicopathological features and prognostic factors of appendiceal neuroendocrine neoplasms(a-NEN). METHODS: Clinical data of 20 patients diagnosed with a-NEN at Zhongshan Hospital of Fudan University between January 2000 and December 2016 were retrospectively analyzed. Pathological diagnosis was based on the WHO classification criteria of digestive system tumors (2010 edition). Based on the mitotic count and Ki-67 index, a-NENs were divided into grade 1 neuroendocrine tumor (NET G1), grade 2(G2) NET G2) and grade 3 (neuroendocrine carcinoma, NEC)...
