Active clinical trials for "Neuroendocrine Tumors"

The objective is to clarify Roux-en-Y anastomosis of the pancreatic stump decreases pancreatic fistula following distal pancreatectomy, compared with stapling closure of the pancreatic stump.

This study is a multi-center, prospective, non-interventional (NI) study evaluating the safety and efficacy of sunitinib in Chinese patients with progressive, unresectable, advanced or metastatic well-differentiated, pancreatic neuroendocrine tumors(pNET). 100 adults with progressive advanced or metastatic well-differentiated unresectable pNET will be recruited in China hospitals. Each subject will be followed up overall survival (OS) time or the date of withdrawal and subjects who remain alive after study completion will have their OS time censored on the last date known to be alive. Eligible subjects will be enrolled to receive at least one dose of sunitinib orally at 37.5 mg once a day on a continuous daily dosing regimen (CDD) or dosage modification is based on daily clinic practice. Subjects will be treated until disease progress, unacceptable toxicity, withdrawal from the study at their own request, or until the final analysis for the study is performed. The NI study will capture observations that will be used for evaluating the safety profile of sunitinib, including: subject demographics, medical history and medications. Safety assessments, treatment data and any other laboratory examination results, which were done according to routine clinical practice, will be collected at all visits.

A descriptive, prospective (partly retrospective), multisite, observational study conducted in France in adult patients treated for a well differentiated, unresectable or metastatic, pancreatic neuroendocrine tumor with disease progression.

Nutritional status in patients with neuroendocrine tumours (NETs), especially of gastroenteropancreatic origin, can be deeply affected by excessive production of gastrointestinal hormones, peptides, and amines, which can lead to malabsorption, diarrhoea, steatorrhea, and altered gastrointestinal motility. Besides, the surgical and/or medical management of NETs can lead to alteration of gastrointestinal secretory, motor, and absorptive functions, with both dietary and nutritional consequences. Indeed, disease-related malnutrition is a frequently encountered yet both underrecognized and understudied clinical phenomenon in patients with NETs, with substantial prognostic and socioeconomic consequences. Most of these conditions can be alleviated by a tailored nutritional approach, also with the aim of improving the efficacy of cancer treatments. In this setting, skilled nutritionists can play a fundamental role in the multidisciplinary health care team in NETs management and their presence should be recommended.

Phase-II, prospective, open label, no control group to assess the safety of 68Ga-DOTA-TATE injection in patients with suspected or diagnosed with tumors expressing somatostatin receptors. Each included patient will receive an administered dose of 50 mcg or less of the peptide (DOTA-TATE) and a range of activity between 100 - 200 MBq of 68Ga-DOTA-TATE. The efficacy of 68Ga-DOTA-TATE in assessing this kind of tumors has been proved by numerous studies.

Neuroendocrine tumors (NETs) are neoplasms originating from neuroendocrine cells located throughout the body. They secret various peptides and cause various symptoms (carcinoid syndrome) or not. The incidence of NETs was not well-known till recently when Yao et al. and Hausa et al. published their surveys of NETs using data from the US Surveillance, Epidemiology, and End Results (SEER) program and from the Norwegian Registry of Cancer (NRC). The incidence of NETs in Taiwan by using the Taiwan Cancer Registry (TCR) data was increased from 0.3 to 1.51 per 100,000 from 1996 to 2008. The increased incidence for NET worldwide probably was partially due to the awareness and improvement of diagnostic technology. Compared with the incidence in western countries, the incidence of NET is much lower in Taiwan. And the incidence of NETs in Asian Pacific Islanders was also lower than the whites and blacks in US. Gastroenteral-pancreatic NETs (GEP-NETs), accounting for half to two thirds of all NETs, is the most common site of NETs. As the progress in the understanding of pathophysiology for GEP-NET, there are two novel targeted agents shown to be effective for the treatment of GEP-NET. Meanwhile, response to mTOR inhibitor was better for Asian than Caucasian in the phase III study using everolimus for advanced pancreatic NETs. These information suggests that there is racial difference for either genetic or environmental risk factors and these factors result in different incidence and/or clinical outcome. Currently, there is limited data for thorough epidemiologic study in Taiwan. The aim of this study is to collect clinical information for GEP-NET, and survey the prognostic factors for GEP-NET in Taiwan. the investigators suppose that this epidemiologic study would provide a database potentially to improve the diagnosis, and treatment of GEP-NET. This study plans to include 600 GEP-NET patients. NET patients diagnosed after 2011.1.1 is included in this study. Furthermore, the investigators will provide the check of immunohistochemical staining for the tumor tissue of GEP-NET patients, including the functioning status (insulinoma, glucagonoma, gastrinoma, VIPoma) and the degree of differentiation, the expression of SSTR2 or SSTR5 and the check of possible primary site for unknown primary NET patients. This examination will provide more accurate diagnosis for the patients and further treatment suggestion for the patients.

The objective of this observational laboratory study is to measure the correlation between 5-hydroxyindolacetic acid (5-HIAA) in platelet rich plasma and 5-HIAA in 24-hours urine collection in adult patients with a serotonin-producing neuro-endocrine tumor. Plasma and urine of included patients are collected and 5-HIAA values are measured with LCMS-MS and analysed.

Neuroendocrine cancer is an unusual disease and often goes undetected by routine imaging. The 68Ga-DOTATATE PET Scan is a novel scanning method that may have improved sensitivity and resolution specifically for neuroendocrine tumors. Patients with neuroendocrine tumors will be imaged with this agent and it will be compared to conventional imaging methods to determine the safety and efficacy of this radiopharmaceutical.

Aim: The aim of this study was to investigate the clinicopathological factors and to evaluate the prognostic accuracy of the new World Health Organization (WHO) 2017 grading system in pancreatic neuroendocrine tumor (PanNET) patients. Methods: Data collected between 1997 and December 2017 were analyzed. Histological grading and staging was based on the WHO 2017 grading system. Outcome after surgery and predictors of overall survival (OS) and disease free survival (DFS) were evaluated.
