Filter by:The purpose of this study is to evaluate the diagnostic performance of [68Ga]Ga-DOTA-TATE Positron Emission Tomography (PET)/Computerized Tomography (CT) imaging compared with conventional imaging (CIM) as standard of truth in patients with neuroendocrine neoplasms (NENs) and healthy volunteers (HVs). The data from this study will provide the evidence for diagnosis of [68Ga]Ga-DOTA-TATE PET/CT imaging in patient with NENs in Japan.
Background: Small cell carcinoma of the bladder (SCCB) and other high-grade neuroendocrine tumors (HGNET) of the urinary tract are rare but aggressive cancers. Average survival for people diagnosed with SCCB or HGNET is about 1 year. Lurbinectedin and avelumab are drugs that are approved to treat other cancers. Researchers want to see if these drugs can help people with SCCB or HGNET. Objective: To test lurbinectedin with or without avelumab in people with SCCB or HGNET. Eligibility: Adults aged 18 years and older with SCBB or HGNET that returned and spread after treatment. Design: Participants will be screened. They will have a physical exam. They will have blood tests and imaging scans. They may need to have a new biopsy: A small needle will be used to collect a tissue sample from the tumor. Both study drugs are given through a tube attached to a needle inserted into a vein. If participants have already received a drug like avelumab they will receive only lurbinectedin. If patients have not been previously treated with a drug like avelumab they will receive both lurbinectedin and avelumab. All participants will receive their treatment once every 3 weeks for up to 10 years. They will also receive other drugs to relieve adverse effects. Biopsies, blood tests, and imaging scans will be repeated during some study visits. Participants may also have urine tests and tests of their heart function. Participants may remain in the study as long as the treatment is helping them. If they stop treatment, they will have safety visits 14, 30, and 90 days after their last dose. Additional follow-up visits will continue 5 to 10 years.
The goal of this clinical trial is to compare CT scan of the coverage of tumors treated with TACE using End Hole catheters to those treated with the TriNav catheter that alters tissue pressure. Both catheters are FDA approved for delivery of TACE. • Is there a difference in CT appearance with delivery in the type of catheter used during the TACE procedure? Participants will be asked to undergo a TACE procedure, a CT scan and review of their medical record to compare End Hole and TriNav catheters during TACE procedures.
Neuroendocrine tumors (NETs) constitute approximately 0.5% of malignancies. To date, diagnosis at an increasingly early stage of the disease is possible thanks to recent technological advances in biomedical imaging. In particular, the traditional work-up for these pathologies includes endoscopy, magnetic resonance imaging (MRI) and computed tomography (CT). Furthermore, the integrated positron emission tomography methods (PET/CT and PET/MRI) are innovative molecular imaging techniques and represent a continually expanding field of research in the oncology setting. In particular, PET is taking on an increasingly relevant role for the study of neuroendocrine tumors, also thanks to the introduction of increasingly accurate radiopharmaceuticals (targeted towards somatostatin receptors), thus opening the way to new possibilities for the diagnosis andcharacterization of these tumors, is in the staging and restaging phase .
Gastroenteropancreatic neuroendocrine tumours (GEP-NETs) are a heterogeneous group of neoplasms that arise from the endocrine cells of the gastroenteropancreatic tract. The diagnostic work-up of these tumours include Computed Tomography (CT), Endoscopic Ultrasound (EUS), Magnetic Resonance Imaging (MRI). The majority of these tumours express somatostatin receptors on their surface. For this reason, in addition to traditional imaging exams, diagnostic work-up of GEP-NETs should include a Positron Emission Tomography/CT with 68Ga labeled somatostatin analogues targeting somatostatin receptors with high sensitivity and specificity. 68Ga-DOTATOC PET/CT scan is a corner stone to assess GEP- NET patients at different stage of disease and it is the standard functional imaging modality to study well-differentiated Pan-NETs, as reported in the being also included in the guidelines of the European Association of Nuclear Medicine (EANM). Moreover, quantitative parameters extracted from 68Ga- DOTA-peptides PET imaging have demonstrated their prognostic utility as markers for progression-free survival and disease specific mortality in patients affected by NET. Additionally, 18F-FDG PET can be used for evaluating the possible presence ofa high-grade component within the tumour itself. The accurate morphofunctional characterization is of utmost importance in the field of GEP-NET. the advent of new hybrid scanners, namely PET/MRI, opens the way to an innovative diagnostic work- up that can be applied to GEP-NETs. In fact, MRI plays a role as morphological imaging modalities for a better characterization of soft-tissue and liver parenchyma compared to CT; moreover, the low radiation exposure related to MRI, makes this imaging modality more suitable for patients requiring several imaging during follow-up. Patients requiring 68Ga-DOTA peptides (68Ga-DOTATOC) PET scan and eventually MRI scan, can be studied in a single session examination, by using 68Ga-DOTATOC PET/MRI. Considering the rarity of GEP_NETs, it is quite difficult to collect a sufficient number of patients in order to investigate the accuracy, predictive and prognostic value of the currently available imaging technique in this scenario. Based on these considerations, the possibility to analyze PET images deriving from both PET/CT and PET/MRI scans of patients affected by GEP-NET is of fundamental relevance in order to provide answers to the currently unmet clinical needs.
Treatment of advanced endocrine tumors, including adrenal corticocarcnioma (ACC), medullary thyroid carcinoma (MTC), thymic neuroendocrine tumor and pancreatic neuroendocrine tumor is challenging. Previous genomic profiling studies showed they presented a number of somatic mutations. The tumors Individualized mRNA neoantigen vaccine provide a promising solution since a significant portion of these tumors showed high quality of tumor specific neoantigen. The primary objective is to observe and evaluate the safety and tolerability of individualized mRNA neoantigen vaccine (mRNA-0523-L001) for the treatment of advanced endocrine tumors, failure of standard treatment or no standard treatment currently available. The secondary objective is to observe the preliminary efficacy of mRNA-0523-L001 for the treatment of advanced endocrine tumors, failure of standard treatment or no standard treatment currently available, including: 1. Neoantigen-specific CD4+ and CD8+ T lymphocyte responses induced by mRNA-0523-L001; 2. Objective response rate (ORR) and disease control rate (DCR) of tumors; 3. Progression-free survival (PFS).
This study is open to adults aged 18 and older or above legal age who have a specific type of advanced neuroendocrine cancer (NEC). Their tumours must be positive for a marker called DLL3. The purpose of this study is to test a medicine called BI 764532 in addition to chemotherapy. The study has 2 parts. Part A of this study aims to find out the highest dose of BI 764532 that people can tolerate in addition to chemotherapy. The purpose of Part B is to find out how well people can tolerate BI 764532 in combination with different chemotherapies. Researchers also want to find out whether BI 764532 in combination with chemotherapy helps people with NEC. Participants get different doses of BI 764532 as an infusion into a vein. In addition, they get platinum-based chemotherapy as infusions into a vein. Participants can continue treatment up to 3 years if they benefit from treatment and can tolerate it. Participants visit their doctors regularly. During these visits, the doctors collect information about participants' health and take note of any unwanted effects. Doctors also regularly check the size of the tumour.
Introduction : The incidence of duodenal neuroendocrine tumors (DNETs) is increasing. Endoscopic resection is recommended for the management of small DNETs measuring ≤10 mm. Various endoscopic techniques have been utilized for the resection of DNETs including endoscopic mucosal resection (EMR), band ligation assisted EMR, endoscopic submucosal dissection (ESD). However, the published studies report a high rate of histologically incomplete resection even with ESD. More recently, device assisted endoscopic full thickness resection (EFTR) has emerged as a safe and effective resection modality in cases with upper and lower gastrointestinal (GI) mucosal as well as submucosal lesions. There is limited data on the outcomes of EFTR in cases with DNETs. In this study, we aim to compare the rate of histologically complete resection (R0) with ESD and EFTR in cases with DNETs.
The goal of this prospective observational study is to generate new personalised 3D preclinical models of pancreatic neuroendocrine tumors. The models will be exploited for studying the mechanisms underlying disease development and progression, as well as for performing drug testing. For the development of the newly proposed models, patients' surgical specimens will be evaluated by the Pathological Unit. If the presence of pathological material in excess, not required for the routine diagnostic procedure, is confirmed, such material will be employed for the generation of the proposed personalised models.
This prospective, single-center, double-blinded study investigates the biodistribution, dosimetry, safety, and diagnostic ability of Al18F-NOTA-LM3 in patients with well-differentiated neuroendocrine tumors. And compares the diagnostic ability of Al18F-NOTA-LM3 with 68Ga-DOTATATE PET/CT and 68Ga-NODAGA-LM3 PET/CT. Clinical management will also be compared using different imaging modalities.
