Active clinical trials for "Neuroendocrine Tumors"

The iCaRe2 is a multi-institutional resource created and maintained by the Fred & Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies.

This study aims to investigate the treatment preferences of patients with Neuroendocrine Tumors (NETS) and nurses who are involved in the care of individuals with NETs. NETs are a type of abnormal growth that can develop in various parts of the body, such as the lungs, pancreas, gastrointestinal tract, or other organs. NETs originate from specialized cells called neuroendocrine cells, which are responsible for producing hormones in our bodies. The study focuses on hypothetical preferences regarding the use of two different type of devices for administering Somatostatin analogues (SSAs), which could be used in the treatment of NETs. SSAs work by imitating the actions of a hormone called somatostatin that naturally exists in our bodies. These treatment help to control the symptoms of NETs by blocking the release of hormones from the tumor cells. The devices under consideration are a motorized injector versus a manual injector. Participants in the study will be asked to take part in: An interview based on a draft survey: 60-minute interview over videocall, to examine participants understanding of the online survey; or Final online survey: 30-minute online survey. This involves presenting patients and nurses with different treatment options and asking them to choose their preferred option. By analysing the choices made by participants, researchers can understand which attributes of the injector devices are most important to patients and nurses. Individual participation is limited to the interview based on a draft survey (60 minutes) or the final online survey (30 minutes). No further participation is required beyond this.

Background: Neuroendocrine neoplasm (NENs)are rare cancers arising from the neuroendocrine cells and can affect almost any part of the body. They vary from low grade neuroendocrine tumors (NETs) to high grade neuroendocrine carcinomas (NECs). These tumors often occur in the gastrointestinal tract, pancreas, lungs, adrenal medulla (pheochromocytomas) or adrenal cortex (adrenocortical cancer) and other areas of the body mentioned below: Gastroenteropancreatic neuroendocrine tumors (GEP-NET): stomach, duodenum, pancreas, colon, appendix, etc. Liver and gallbladder Adrenal tumors Pituitary gland Thyroid gland: medullary thyroid carcinoma Parathyroid tumors Pulmonary neuroendocrine tumors: typical and atypical carcinoid, small cell lung cancer (SCLC), large cell neuroendocrine carcinoma (LCNEC) Extrapulmonary small cell cancer Peripheral nervous system tumors: paraganglioma, neuroblastoma) Breast and genitourinary tract Their rates are rising in the United States and worldwide. Researchers want to learn more about NENs through this natural history study. Objective: To study the natural history of people with NENs and obtain samples from them to learn more about the disease. The clinical management of all NETs is not standardized, with only a few FDA-approved therapies and we would like to learn which combination therapeutic approach should be used, how long treatment should be continued, and in what subgroup of NENs a particular treatment option should be used. Eligibility: People aged 18 and older who have or are suspected to have NENs or ACC. Design: Participants will be screened with a medical history. Participants will have a physical exam. Their symptoms and their ability to perform their normal activities will be reviewed. They will have blood and urine tests. Participants will receive recommendations for managing their disease and potential treatment options. They will be able to ask as many questions as they would like. Participants may provide saliva, blood, and stool samples for research. They will give tumor samples from a previous surgery or biopsy. Participants may have optional biopsies. During biopsies, cancer tissue will be obtained using a needle and syringe. Tissue will be taken from the liver, lung, or a lymph node. Participants may have an imaging scan or ultrasound to help locate the tumor or area to be biopsied. They will receive local anesthesia and may be sedated. Participants will complete a questionnaire about their family medical history. Participants will have follow-up visits every 6 months. They will have physical exams and give samples. If their health changes, they may have extra visits. If they cannot visit NIH, they (or their doctor) will be contacted by phone or email. Participants will take part in the study for all their life.

This is a prospective cohort study. The investigators enroll subjects with pancreatic ductal adenocarcinoma (PDAC), individuals at high risk for PDAC, patients with other pancreatic diseases, patients with CA19-9 elevation and controls without pancreatic disease. This study aims to establish a diagnostic prediction model by using elastase 1, common clinical serological examinations, and imaging examinations including endoscopic ultrasonography (EUS), and to explore the diagnostic ability of the model in the high-risk population of PDAC. Besides, the investigators search for new biomarkers by multi-omics studies of serum and pancreatic tissues to further improve the diagnostic performance of this model. In conclusion, this study seeks a robust diagnostic prediction model to diagnose PDAC, especially early resectable PDAC.

Background: - Lung cancer is the leading cause of cancer-related death worldwide. It causes more than one million deaths every year. Researchers want to gather tissue samples from people with lung and thymic cancers to understand the disease better. This may lead to new ways to diagnose and treat it. Objective: - To collect tissue samples for use in the study of lung cancers. Eligibility: - Adults over age 18 with non-small cell lung cancer, small cell lung cancer, extra pulmonary small cell cancer, pulmonary neuroendocrine tumors, and thymic epithelial tumors. Design: Participants will be screened with a medical history, physical exam, and blood tests. They will be asked about how they perform their daily tasks. Participants may be asked to give urine and blood samples. They may give a saliva sample if they cannot give blood. They will also give a sample of their tumor from a biopsy they had. They may also be given the option to undergo a biopsy. Participants may have MRI, CT, and/or PET scans of the body. They will lie in a machine that takes pictures of the body. After visits to the Clinical Center end, researchers will contact participants by phone every year to check on their health.

Small Intestinal neuroendocrine Tumors (SiNETs) incidence is rising. Most of siNETs primaries are localized in jejunum/ileum. At the diagnosis, 50-70% of them present either lymph node (LN) and/or liver metastases (LM). It is admitted that almost 30% of the patients present or will present primary complications. Primary complications include endoluminal obstruction and/or LN-fibrotic mesenteritis with occlusive symptoms, and less frequently haemorrhage and/or intestinal ischemia.However, it is not clear weather this affects patient with or without multiple liver metastases (LM). In this regard, many centres propose to perform primary resection even in patients presenting unresectable LM. Thus, systemic reviews suggest a possible benefit of the primary midgut siNETs resection even in patients with unresectable LM, there is no prospective randomized trial showing the benefit of primary resection in such patients especially those who are totally asymptomatic. Indeed, all retrospective published series have several limitations and the results should be therefore considered with caution. Theoretical impact of "preventive" resection of midgut primaries in patients with unresectable LM and totally free of occlusive symptoms is controversial. Firstly, it is to avoid primary mechanical complications, and secondly to allow targeting therapeutics to the liver compartment. In this regard, in patients with synchronous unresectable LM from siNENs, ENETS, UKINETS, NANETS guidelines propose, in "a case-by-case" selective approach, the resection of the primary, while NCCN guidelines advocate to do not propose primary resection in such patient if they are free of symptoms with low tumor burden.

The biology of pancreatic neuroendocrine tumors can change during the disease course. This evolution of disease can manifest through increases in tumor proliferation rate, resistance to medical therapy and/or a change in tumor hormone secretion. This study aims to characterize how the biology of pancreatic neuroendocrine tumors change over time, measured by; patient symptoms, biochemistry, contrast enhanced computed tomography, DOTATOC-PET, FDG-PET and core needle biopsy with histopathological analysis (Ki67 index and tumor cell differentiation). Uptake on 68Ga-DOTATOC and 18F-FDG-PET will be correlated directly to tumor cell proliferation rate. Fraction of patients with spatial heterogeneity in DOTATOC as well as FDG uptake as well as metachronous changes in all collected data will be documented. Biomaterial from whole blood and core needle biopsies will be characterized on the molecular level, and those findings will be integrated to the above specified clinical parameters.

This is a prospective observational study with the aim to create an Italian database for the collection of data on diagnostic approach, therapy and follow up of patients affected by GEP-NET (gastro-enteric-pancreatic neuroendocrine tumours). Data for approximately 200 italian patients were already previously collected in the ENETS database (international database). ENETS decided to interrupt the collection of the data for an indefinite period. For this reason, through an amendment (number 1) to the protocol, ITANET (Italian Association Neuro-endocrine Tumors) decided to transfer the italian data into a national database and to go on with the collection/update of the data, in order not to lose important clinical information.

The variable clinical outcome of patients with G2 & G3 well diff GEP-NETs makes the selection of an optimal treatment strategy challenging. Initial data suggests that high DOTATATE uptake and low FDG uptake are suggestive of low grade disease, with an indolent course. Conversely, low DT uptake and high FDG uptake are suggestive of high-grade/ aggressive disease. G2/3 GEP NETs may be biologically diverse; clinically relevant cohort for dual-tracer PET imaging. Our secondary objectives are To determine the distribution of PETNET scores derived from 18F-FDG & 68Ga-DT PET in patients with G2 & G3 well diff GEP-NETs. To determine the proportion of patients in whom the addition of 18F-FDG PET data results in a change in planned clinical management. To assess intra-individual variability in SSTR expression & glucose metabolism (as seen on DT and FDG PET) across different tumor sites within the same patient. 2) To determine whether a correlation exists between tumor texture features on 68Ga-DT & FDG PET to tumor grade and Ki 67 index. 3) To assess for an association between tumor texture features on 68Ga-DT PET and glucose metabolism; and/or an association between tumor texture features on FDG PET and SSTR expression.

This is a prospective observational multi-center pilot study of germline testing for participants receiving care at University of California participating locations with a new or existing diagnosis of Pancreatic Neuroendocrine Neoplasms (PanNEN). This protocol is an extension of existing Genetic Testing Station efforts at University of California, San Francisco (UCSF)
