Filter by:A prospective clinical trial to study the safety and effectiveness of Transcatheter Artery Chemotherapy and Embolization (TACE) using CalliSpheres Drug-Eluting Beads with oxaliplatin (DEBOXA) in treating patients who have inoperable neuroendocrine neoplasm (NEN) liver metastases.
This phase I trial studies the side effects of survivin long peptide vaccine and how it works with the immune system in treating patients with neuroendocrine tumors that have spread to other parts of the body (metastatic). Tumor cells make proteins that are not usually produced by normal cells. The body sees these proteins as not belonging and sends white blood cells called T cells to attack the tumor cells that contain these proteins. By vaccinating with small pieces of these proteins called peptides, the immune system can be made to kill tumor cells. Giving survivin long peptide vaccine to patients who have survivin expression in their tumors may create an immune response in the blood that is directed against neuroendocrine tumors.
Neuroendocrine tumours (NETs) are rare and include a heterogeneous group of neoplasms derived from the endocrine system found in the gastrointestinal tract, pancreas and lung. Gastroenteropancreatic (GEP) NETs represent the majority of neuroendocrine neoplasms (NEN) and the annual incidence of all GEP-NETs has been estimated to 6.98 per 100,000 person-years in 2012 and is steadily rising. While data on the incidence of metastatic GEP-NET is limited, more than 50% of patients with GEP-NET have metastatic disease at the time of diagnosis. Incorrect and delayed diagnoses are still common. Treatment options include surgery, locoregional interventions, and systemic treatment. The Lyon Real world Evidence in Metastatic NeuroEndocrine Tumours study (LyREMeNET) is a descriptive observational cohort study. The main objective is to assess the healthcare resources use and the corresponding costs for management of patients with metastatic GEP and lung NETs. The secondary objective is to describe the clinical characteristics, prognostic factors, treatment patterns, and the overall survival among patients with metastatic GEP and lung NETs.
There are several types of early pre-cancerous lesions found in the pancreas which have the potential to develop into pancreatic cancer. Although different patients' pancreatic cancers or pre-cancerous pancreatic lesions have many similarities we believe that subtle differences can affect how they behave and therefore influence individual patient outcomes. Many factors may account for the differences seen in pancreatic lesion behaviour, for example molecular and genetic differences (the DNA and RNA present which control how a cell grows and divides), differences in how the immune system responds to the lesion, differences in the environment immediately around the lesion in the pancreas, known as the tumour microenvironment and differences in the micro-organisms which colonize a particular patient, known as their microbiota . This project studies the molecular makeup of pancreatic lesions and their microenvironment at various stages (from pre-cancerous lesions all the way through to more advanced disease) to see if we can use this information to divide patients into different groups whose lesions may behave in similar ways. We will be trying to find out if there are molecular reasons why some patients respond to particular treatments when others do not, why some patients experience more toxicity with particular treatments and why some patients' disease behaves particularly aggressively when other patients' disease does not. We will also be investigating the particular micro-organisms colonizing individual patients to see if these impact a patient's outcome. Understanding what makes one person's pancreatic lesion behave differently to another's could lead to better treatment, where a personalized therapeutic strategy could be applied for every single patient.
This study evaluates the efficacy of Long-acting Somastostatin analogs as treatment for type I gastric neuroendocrine tumors.
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.
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics, and determine the maximum tolerated dose of ZSP1602 in participants with basal cell carcinoma, adenocarcinoma of esophagogastric junction, small cell lung cancer, neuroendocrine neoplasm and other advanced solid tumors.
NET originate in neuroendocrine cells throughout the body. The goal of this study is to assess the safety and efficacy of the combination of everolimus and the intravenous radiolabeled Lu-177 DOTATATE Therapy as a 1st line therapy in unresectable well to moderately differentiated metastatic neuroendocrine tumors of all GI, lung and pancreatic origins. This is a phase 1 - 2 study. The phase 1 part involves finding the maximum tolerating dose (MTD) of Everolimus.
Neuroendocrine tumours (NETs) are generally slow growing, but some can be aggressive and resistant to treatment. Compared to healthy cells, the surface of these tumor cells has a greater number of special molecules called somatostatin receptors (SSTR). Somatostatin receptor scintigraphy and conventional imaging are used to detect NETs. This study proposes 68Gallium(68Ga)-DOTATOC positron emission tomography/computed tomography (PET/CT) is superior to current imaging techniques. The goal is to evaluate the safety and sensitivity of 68Ga-DOTATOC PET/CT at detecting NETs and other tumors with over-expression of somatostatin receptors.
Neuroendocrine tumors (NET) are a network of rare tumors with common embryological origin. Functional imaging plays a major role in the extension assessment and tumor characterization of NETs. SPECT/CT with 111In-pentetreotide is the recommended test when tumors are well differentiated (grade G1 or G2). It has a real interest in diagnosis, in therapeutic decision-making (in particular by cold somatostatin analogues or in PRRT) and in the systematic follow-up of patients. Nevertheless, SPECT/CT procedure makes for a relatively long review. In addition, scintigraphy has a lower spatial resolution than PET technology and remains of limited interest for signal quantification. However, the ability to locate and quantitatively measure the absorption of radiopharmaceuticals in the target tissues is a major challenge in oncology for the characterization of the disease. Recent developments in radiopharmacy have made it possible to target NETs in PET imaging through the use of somatostatin analogues coupled with positron emitters, called 68Ga-DOTA peptides. The diagnostic performance of 68Ga-DOTApeptide PET/CT appears to be superior to SPECT/CT with 111In-pentetreotide. A marketing authorization has thus recently been issued in France for the use of 68Ga-DOTATOC. Historically, the recommended quantification method in PET was based on the instantaneous measurement in static acquisition (3D) of the maximum of the standardized uptake value (SUVmax). This approach has the disadvantage to measure the signal at a time "t" for a single voxel of the image. Dynamic acquisition methods (4D) have been proposed to extract a radiotracer absorption coefficient (Ki) for a lesion. Several studies have demonstrated the superiority of Ki versus SUVmax in 18FDG PET/CT for the diagnostic management, therapeutic evaluation and prognosis of various solid cancers. However, no work has validated this approach in PET / CT at 68Ga-DOTATOC as part of the prognostic evaluation of NETs. The objective of the study is to evaluate the prognostic value of the tumor absorption coefficient Ki resulting from a 4D whole-body dynamic acquisition in PET / CT at 68Ga-DOTATOC in patients with well-differentiated NETs grade I or II according to the WHO classification
