Filter by:Somatostatin receptor antagonists are emerging agents in molecular imaging of neuroendocrine tumors. There're two main antagonist peptides, namely JR11 and LM3, which can be coupled with different chelators, DOTA and NODAGA. Previous studies by our and other groups have revealed the different diagnostic performances of these tracers. However, head-to-head comparison data is still missing. In this study, we aim to evaluate the diagnostic performance of four different antagonists, that is, NODAGA-LM3, DOTA-LM3, and NODAGA-JR11, all labeled with gallium-68.
Background: Neuroendocrine neoplasms (NENs) are rare tumors that originate in neuroendocrine cells. NENs can affect almost any part of the body. People with low-grade tumors can live many years. But high-grade tumors can be very aggressive. Researchers want to learn more about this type of cancer. This may help them design better treatments and supportive care studies. Objective: To gain a better understanding of neuroendocrine neoplasms. Eligibility: People starting at age 3 and older who have or are suspected of having NENs and are enrolled in protocol 19C0016, Natural History and Biospecimen Acquisition Study for Children and Adults with Rare Solid Tumors Design: Participants will be screened with questions about their medical history. This may be done over the telephone or in person. Participants medical records, test results, and imaging results will be reviewed. They may have scans and blood tests. They may sign a separate consent form for some of the tests. Participants will complete paper or electronic surveys. The surveys will ask about the effects of cancer on their wellbeing. Participants may give samples of their tumors from previous surgeries or biopsies. These samples will be used to study their tumor genes. Participants will get advice on how to manage their NENs. They will also get recommendations about potential treatment options. Participants home doctors will be contacted every 6 to 12 months. They will give medical data such as imaging and test results. Participants may have follow-up visits at NIH every 6 to 12 months. Participants will contact researchers if there are any changes in their tumor. Participants will be followed on this study for life.
Malnutrition and loss of muscle mass frequently occur in patients undergoing chemotherapy and can negatively effect therapy outcome. Especially patients with cancer of the gastrointestinal tract are often affected by malnutrition. Therefore, this study aims to examine changes in nutritional status of patients with cancer of the gastrointestinal tract during chemotherapy. Findings of this study will help to improve nutritional treatment of patients undergoing chemotherapy.
This is a multicentre, controlled, observational prospective study on new biomarkers, as immune profiling, angiogenetic markers and circRNA from TEPs in the diagnosis and in the evaluation of treatment response in pulmonary and gastro-entero-pancreatic NENs.
This exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers.

A huge number of initiatives about COVID-19 are ongoing and a growing number of publications regard the correlation between cancer patients in general and SARS-CoV-2 infection. Although it has been reported that cancer patients are at a higher risk of SARS-CoV-2 infection and COVID-19 complications, data collection about cases of NEN patients SARS-CoV-2 positive are scattered and related to single countries or institutions. Because of that and due to the rarity and heterogeneity of NEN it will be hard to have homogeneous, reliable, representative and reproducible data for drawing adequate clinical recommendations about NEN patients and COVID-19. Therefore we propose a global collection of data through an international database to describe and monitor NEN patients with SARS-CoV-2 infection. This retrospective/prospective collection of data can create a solid basis to check frequence of events, clinical management, clinical outcome, demographic, geographical, clinical and biological correlations. This will be helpful for the clinical and scientific community to get reliable information for a homogeneous clinical management of NEN patients during COVID-19 pandemic. The main goal is to get the as wide as possible representativity of the world situation.
The primary purpose of this study is to examine the safety and potential effectiveness of a drug molecule called 64Cu-SARTATE as a potential new way to detect neuroendocrine cancers.
The purpose of this study is to assess the performance of imaging agent 64Cu-SARTATE in participants with known or suspected Gastroenteropancreatic (GEP) Neuroendocrine Tumors (NETs) as a potential new way to help diagnose NETs.
This is a prospective study of rare neuroendocrine and adrenal tumors. Subjects will be enrolled via informed consent, and blood and/or saliva and tissue will be collected. This is designed to work in conjunction with IRB#831990 which is a retrospective protocol. The University of Pennsylvania will be a contributing site with the University of Michigan as the coordinating site for the A5 alliance, a multi-institutional collaborative designed to study neuroendocrine and adrenal tumors.
