Pancreatic neuroendocrine neoplasms (pNENs) are a group of clinically rare and heterogeneous diseases of the pancreas. However, the prognostic factors for this disease in patients still remain controversial. The purpose of our study is to evaluate the predictive roles of those prognostic factors for pNENs. All related articles published until Sep 17, 2017 were identified via PubMed, EMBASE, Web of Science, Ovid and the Cochrane Library. Studies that examined the prognostic factors of pNENs were enrolled. 17 articles (2822 patients) were finally included in this study...

Pancreatic neuroendocrine neoplasms (PNENs) are extremely rare neoplasms of the pancreas. They originate from pancreatic islet cells, and from the very beginning, cancer cells may or may not show hormone hypersecretion. Currently, surgical treatment is the only therapeutic method that significantly prolongs life expectancy, and in such cases it is a method of choice. In the paper, a review of literature based on the Medline database and including mainly the period of 2013 to 2017 was performed. In each case an operating surgeon is responsible for selection of a method used for surgical treatment...

Roxanne Y A Teo, Brian K P Goh
Over the past decade, there has been increasing adoption of minimally invasive pancreatic surgery world-wide and this has naturally expanded to the management of pancreatic neuroendocrine neoplasms (PNENs). More recently, robotic pancreatic surgery (RPS) was introduced to overcome the limitations during laparoscopic pancreatic surgery (LPS). Due to the relative rarity of PNEN and the novelty of minimally invasive pancreatic surgery in particular RPS today, the evidence for robotic surgery in PNENs remains extremely limited...

PURPOSE: Emerging evidence suggests G3 pancreatic neuroendocrine neoplasms (pNENs) present heterogeneous morphology and biology. The 2017 WHO classification has introduced a new category of well-differentiated pancreatic neuroendocrine tumors (WD-pNETs) G3, compared with poorly differentiated pancreatic neuroendocrine carcinomas (PD-pNECs) G3. We aim to analysis the demographics and outcomes of patients with resectable 2017 WHO G3 pNENs to facilitate the distinction between two entities...

BACKGROUND: Pancreatic neuroendocrine tumor(P-NET)is relatively rare and often has less aggressive biological behavior. P-NET was re-designated by the WHO in 2010 and 2017. Laparoscopic surgery is minimally invasive but has technical difficulties such as limitation of movement and laparoscopic view. The purpose of this study is to evaluate the efficacy of laparoscopic pancreatectomy(LPT)for P-NET. METHODS: Between January 2012 and June 2017, 6 patients underwent LPT for P-NET at Kansai Rosai Hospital...

BACKGROUND: The role of N classification is controversial in several prognostication systems proposed for pancreatic neuroendocrine neoplasms (pNENs). The widely accepted modified European Neuroendocrine Tumor Society (mENETS) system suggests this contradiction may be related to T classification. METHODS: Data were collected retrospectively from 981 patients in the Surveillance, Epidemiology, and End Results (SEER) database (1973-2012; cohort 1) and 140 patients from the Pancreatic Cancer Institute of Fudan University (2006-2016; cohort 2)...

PURPOSE: Chromogranin A (CgA) and neuron-specific enolase (NSE) are important markers for neuroendocrine tumors; however, the clinical value of combining these markers has not been well studied. In this study, we investigated the utility of each marker individually and in combination for patients with nonfunctional pancreatic neuroendocrine tumors (NF-pNETs). PATIENTS AND METHODS: In this study, NF-pNET patients and controls were recruited from December 2011 to March 2016; 784 serum samples from peripheral vein were collected...

Background: Pancreatic neuroendocrine neoplasias (pNENs) are uncommon but fascinating tumors with an annual incidence of 1 per 100,000 people. pNENs present either as functional tumors, causing specific hormonal syndromes like Zollinger-Ellison syndrome (ZES) or organic hyperinsulinism, or as non-functional pancreatic tumors (NF-pNENs). The natural history of pNENs is highly variable. 90% of all insulinomas or small NF- pNENs are readily curable by surgical resection. Most other functional and late detected NF-pNENs have a less favorable chance for cure...

BACKGROUND: The recently released AJCC TNM staging system of pancreatic adenocarcinoma has endorsed the number of positive lymph node(NPLN) as the criterion of N staging. However, the prognostic role of NPLN is still unclear for pancreatic neuroendocrine neoplasms (pNENs). METHODS: Patients underwent resection and at least one lymph node examined were identified from the Surveillance, Epidemiology, and End Results database. The overall survival (OS) and disease specific survival (DSS) were estimated using Kaplan-Meier analysis and compared by log-rank test...

Pancreatic endocrine neoplasias (pNENs) are uncommon but fascinating tumors with a rising incidence. In accordance to its location, size and grading, the decision to operate the patient should always be made in an interdisciplinary approach. This article provides a comprehensive review of the current literature addressing the current challenges in pNEN surgery and shows that patients with completely resected small pNENs generally have an excellent prognosis, but also that surveillance may be a powerful tool...

BACKGROUND: Radiological tumor size of non-functioning pancreatic neuroendocrine neoplasms (Nf-pNENs) associated with multiple endocrine neoplasia type 1 (MEN1) is a crucial parameter to indicate surgery. The aim of this study was to compare radiological size (RS) and pathologic size (PS) of MEN1 associated with pNENs. METHODS: Prospectively collected data of MEN1 patients who underwent pancreatic resections for pNENs were retrospectively analyzed. RS was defined as the largest tumor diameter measured on endoscopic ultrasound (EUS), magnetic resonance imaging (MRI) or computed tomography (CT)...

Liver metastasis is the one of the main prognostic factors of pancreatic neuroendocrine neoplasm (PNEN). With the development of multidisciplinary collaboration among surgical oncology, medical oncology, and intervention treatment, the treatment of PNEN with liver metastasis gradually tends to become diversification. Surgery is still the only way for curing the patients with pancreatic neuroendocrine tumor with liver metastasis when the histological types are G1 and G2. Medical oncology and intervention treatment could be selected for those having PNEN with diffuse liver metastasis or those cannot tolerate surgery...

BACKGROUND: The management of small (≤20 mm), nonfunctioning pancreatic neuroendocrine neoplasms (pNENs) remains under debate. The European Neuroendocrine Tumor Society guidelines advocate the possibility of a conservative approach. METHODS: A systematic literature search was conducted to identify all studies comparing the risk of malignancy in small pNENs with respect to large ones (>20 mm). Malignancy was defined based on the presence of nodal metastases...

Pancreatic neuroendocrine neoplasms (PNENs) represent 10% of all pancreatic tumors by prevalence. Their incidence has reportedly increased over recent decades in parallel with that of pancreatic adenocarcinoma. PNENs are relatively rare, and of the few institutions that have published potential risk factors, findings have been heterogeneous. Our objective was to investigate the association between potential risk and protective factors for the occurrence of sporadic PNENs across a European population from several institutions...

This article presents updated diagnostic and therapeutic guidelines for the management of pancreatic neuroendocrine tumours (PNEN), proposed by the Polish Network of Neuroendocrine Tumours. The guidelines contain new data received in the years 2013-2016, which confirm previous recommendations, and have led to modification of previous guidelines or have resulted in the formulation of new guidelines. Biochemical and imaging (anatomical and functional) tests are of great importance in diagnostics, as well as histopathological diagnosis to determine the management of PNEN patients, but they must be confirmed by an immunohistochemical examination...

INTRODUCTION: Pancreatic neuroendocrine neoplasms (pNENs) are relatively rare tumors representing 1% to 2% of all pancreatic neoplasms. These tumors can secrete a variety of biologically active substances giving rise to distinct clinical symptoms or can be clinically nonfunctioning. Apart from insulinomas and gastrinomas, which constitute the majority of functioning pNENs, some tumors may secrete serotonin presenting with the features of the carcinoid syndrome. These so-called pancreatic carcinoids are considered relatively rare tumors and are associated with increased urinary levels of 5-hydroxyindoleacetic acid (5-HIAA)...
