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)...

Pulmonary carcinoid tumors occur in both central and peripheral locations, and some differences in clinico-pathological features have long been observed. We investigated a large number of resected carcinoid tumors with the aim to further define the characteristics of tumors from both locations. One hundred sixty-six resected carcinoid tumors of the lung were analyzed for a variety of clinical and pathologic features, including histology subtype, mitotic rate, Ki67 index, necrosis, invasive pattern, architectural pattern, cell morphology, sustentacular cells, neuroendocrine hyperplasia, and orthopedia homeobox protein (OTP) and TTF-1 immunohistochemical expressions...

BACKGROUND: Two types of ectopic Cushing syndrome (ECS) are described: ECS associated with aggressive neoplasms, and ECS with indolent and occult tumors, however, there is a lack of studies that thoroughly review their characteristics. METHODS: A systematic review was carried out on PUBMED of all the papers about the ECS, in order to better define the types of this subcategory of Cushing's syndrome, highlighting the differential aspects between these subgroups. RESULTS: It was found that in 50% of cases the prototypic "aggressive" ECS is caused by small cell lung carcinomas (SCLC)...

Primary malignancies of the appendix are rare. Of these, less than 5% are goblet cell carcinoid (GCC) tumours. The majority of GCC present with findings of acute appendicitis or advanced peritoneal spread. We describe a rare presentation of GCC as subtle mucosal abnormality of the appendiceal orifice seen on colonoscopy performed for iron-deficiency anaemia. Biopsies were interpreted as adenocarcinoma; however, final surgical pathology confirmed GCC of the appendix with caecal involvement. The patient recovered well from surgery, anaemia resolved and follow-up did not show metastatic disease...

Ribonuclease T2 (RNASET2) is a pleiotropic and polyfunctional protein, which exerts several different activities in neoplastic cells since the early steps of tumor development. Besides having an antitumorigenic activity, RNASET2 inhibits both bFGF-induced and VEGF-induced angiogenesis and has a role as a stress-response, alarmin-like, protein. In this study, we investigated RNASET2 expression in well-differentiated and poorly differentiated neuroendocrine neoplasms of the lung (Lu-NENs), which are known to show clear-cut differences in morphology, biology and clinical behavior...

Neuroendocrine tumors (NETs) are rare, representing 0.5% of all newly diagnosed malignancies. Rectal and anal canal (AC) NETs account for less than 1% of all rectal and AC cancers. Review our institutional experience on NET of the rectum and AC, with emphasis on demographic, histological and treatment features and oncologic outcomes. The study group was identified from the Portuguese Regional South Oncological Registry. From 2000 to 2014, 22 patients with rectal or AC NETs were treated at our institution. Medical records were retrospectively reviewed...

We report a case of an atypical pulmonary carcinoid with high serum ProGRP. A 78-year-old man was found to have an abnormal shadow by a chest X-ray. Chest computed tomography (CT) revealed a solitary pulmonary nodule in the right middle lobe, which was homogeneous, well demarcated, and round. The level of serum ProGRP was elevated to 104.6 pg/ml (normal<81 pg/ml). The nodule was suspected to be a pulmonary carcinoid tumor, and a right middle lobectomy with mediastinal lymph node dissection was performed...

REVIEW
Aimee R Hayes, Ashley B Grossman
Despite modern imaging techniques, differentiating ectopic adrenocorticotropic hormone (ACTH) syndrome from pituitary-dependent Cushing's syndrome, Cushing's disease, is especially difficult when well-differentiated carcinoids are the source of ACTH secretion, particularly pulmonary carcinoid tumors. ACTH-secreting pulmonary carcinoids, like the corticotroph adenomas causing Cushing's disease, are often small and difficult to detect, and patients present with a gradual onset of the classical signs and symptoms of Cushing's syndrome, indistinguishable from the presentation of Cushing's disease...

Peptide Receptor Radionuclide Therapy (PRRT) is a form of molecular targeted therapy which is performed by using a small peptide (somatostatin analogue - SSA) that is coupled with a radionuclide beta emitting radiation. PRRT is a nuclear medicine for the systemic treatment of non-resectable, metastasized well/moderately differentiated, neuroendocrine tumours (NET) with overexpression of somatostatin receptor. These types of tumours include gastroenteropancreatic neoplasm (GEP-NENs), e.g. arising from the small bowel (often called carcinoid tumours), the pancreas, duodenum or stomach, but also from the large bowel or the lung and many other tissues (so called diffuse neuroendocrine system)...

Previous studies have identified potential risk factors for pulmonary carcinoid tumors and evaluated the effect of various treatments; however, the results were not entirely consistent. We conducted a population-based study to further explore relevant prognostic issues. We extracted cases with pulmonary carcinoid tumors from the Surveillance Epidemiology and End Results database. Cox proportional hazard regression was utilized to identify potential significant risk factors, which helped establish a nomogram for predicting long-term survival...

Primary carcinoid tumors of the middle ear are uncommon. Cytodiagnosis of the middle ear is not usually performed as a preoperative examination because of the anatomical structure of the middle ear. To the best of our knowledge, the present study reports for the first time a case of a carcinoid tumor of the middle ear, which was preoperatively diagnosed using cytodiagnosis, and also review current literature. A 22-year-old woman complained of left-sided otalgia. A subcutaneous tumor in the left middle ear was observed...

Rosai-Dorfman disease (RDD), or sinus histiocytosis with massive lymphadenopathy, has been described involving both lymph nodes and extranodal sites, but extranodal RDD rarely involves the gastrointestinal tract. Although the etiology is unclear, several risk factors have been shown to be highly associated with this disease process, including viral infection and immune alterations. In this article, we present a case of a 79-year-old male with a history of autoimmune atrophic gastritis and multiple carcinoid tumors of the stomach presenting with a new stomach mass...

Duodenal carcinoid tumors, a type of neuroendocrine tumors, are relatively rare and are usually found incidentally during endoscopy. Small duodenal carcinoid tumors (≤10-20 mm), embedded in the submucosa, can be resected endoscopically because of the low risk of metastasis. The aim of this study was to assess the safety and efficacy of ligation-assisted endoscopic mucosal resection (EMR) for the treatment of small duodenal carcinoid tumors. The clinical outcomes of the endoscopic procedures were also evaluated...

OBJECTIVES: Minimally invasive surgery is accepted for early-stage lung cancer, but its role in locally advanced disease is controversial, especially using a robotic platform. The aim of this retrospective study was to assess the safety and effectiveness of robot-assisted resection in patients with Stage IIIA non-small-cell lung cancer (NSCLC) or carcinoid tumours in the series as a whole and in different subgroups according to adjuvant treatment. METHODS: This was a retrospective multicentre study of consecutive patients with clinically evident or occult N2 disease (210 NSCLC and 13 carcinoid) who, in 2007-2016, underwent robot-assisted resection at 7 high-volume centres...

BACKGROUND: Urinary vanillylmandelic acid (VMA) and homovanillic acid (HVA) are biomarkers for the diagnosis and follow-up of neuroblastoma, whereas urinary 5-hydroxyindoleacetic acid (5-HIAA) is used to assess a carcinoid tumor. These analytes are conventionally analyzed in a single run by chromatography (LC) coupled with electrochemical detection (LC-ECD) using commercial kits. A rapid dilute-and-shoot LC tandem mass spectrometry (LC-MS/MS) assay was validated in order to replace the LC-ECD method and therefore improve analytical specificity and throughput...

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a new laparoscopic administration of chemotherapy for peritoneal metastasis (PM). PIPAC is repeated every 5th week, and seems to stabilize or improve quality of life, and might improve survival. So far, PIPAC has been well tolerated. With this paper, we aim to highlight a potential severe adverse reaction, as we describe the first cases of severe peritoneal sclerosis (SPS) caused by PIPAC. Patients with isolated PM were included in a prospective PIPAC protocol...
