Filter by:The purpose of this study is to assess the safety and tolerability of 68Ga-OPS202 used for the diagnosis of gastroenteropancreatic neuroendocrine tumors (GEP NETs).
This phase I trial studies the side effects and best dose of sapanisertib and ziv-aflibercept in treating patients with solid tumors that have come back (recurrent) and have spread to another place in the body (metastatic) or cannot be removed by surgery (unresectable). Sapanisertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Ziv-aflibercept may stop the growth of solid tumors by blocking the growth of new blood vessels necessary for tumor growth. Giving sapanisertib with ziv-aflibercept may kill more tumor cells.
Gastro-Entero-Pancreatic tumors (GEPs) are a subset of Neuroendocrine tumors (NETs) derived from the primitive gut and include digestive and bronchial NETs. Historically, the gold standard in their functional exploration is the "conventional" somatostatin receptors scintigraphy (SRS) labeled with Indium-111 (Octreoscan®). This reference imaging is complementary to Tomography (CT) and liver MRI. However SRS sensitivity is moderate (60 %), because of its intrinsic detection limits, which could delay the diagnosis or lead to inappropriate therapy. The use of somatostatin agonists (DOTATOC, DOTATATE, DOTANOC), radiolabeled with gallium-68 (68Ga) enables targeting of Somatostatin receptors (SSTRs) with a PET resolution. This has improved diagnosis of TNE with a gain in sensitivity of over 20% compared to SRS. Furthermore, patient irradiation and imaging protocol are significantly reduced.
Rationale: Patients with neuroendocrine tumors (NET) have a rare disease. Due to treating patients with a neuroendocrine tumor in 'NET knowledge centers' patients often have to travel long distances for follow-up visits at the outpatient clinic. Patients whose medical condition allows videoconsultation could save time by replacing outpatient clinic visits through videoconsultation for receiving follow-up care. Therefore, in this study we aim to introduce videoconsultation as a alternative for follow-up outpatient clinic visits in NET patients. Objective: The primary objective is to assess if use of videoconsultation in follow-up care for NET patients is feasible. We hypothesize that videoconsultation is a suitable medium for providing follow-up care in NET patients. Secondary objectives are to explore the amount of time videoconsultation takes in comparison with outpatient clinic visits and the acceptability and satisfaction of physicians and patients with using videoconsultation in follow-up care. Study design: The present study is a single-centre prospective feasibility study. Study population: Adult NET patients under surveillance or treatment of the department Medical Oncology at the University Medical Centre Groningen (UMCG) whose medical condition allows videoconsultation will be invited to participate. Intervention: Patient who give informed consent will participate in the study. Participants will receive follow-up care through videoconsultation instead of conventional visits at the outpatient clinic. Main study parameters/endpoints: The main endpoint is the feasibility of videoconsultation for follow-up care in NET patients. We hypothesize that videoconsultation is a suitable medium for providing follow-up care.
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.
Through the investigators involvement in an international consortium, the investigators had the opportunity to acquire a new type of synthetizer for the radiolabelling of such tracers. The investigators propose in this project to develop on their site, the radiosynthesis of 68Ga-DOTATOC and to evaluate prospectively the diagnosis of neuroendocrine tumors, compared with the current imaging OctreoScan®. The objectives of this project are: - to validate the radiosynthesis of 68Ga-DOTATOC on their site with a new synthetizer - and clinically evaluate, through a prospective preliminary study, the diagnostic accuracy of PET-CT with 68Ga-DOTATOC in comparison with other standard imaging examinations.
This study will investigate the safety, symptoms and biomarker response of subjects with biopsy-proven well-differentiated, low-to-intermediate-grade, unresectable, or metastatic pancreatic neuroendocrine tumors (PNETs) or or Gastrointestinal Neuroendocrine tumors (GI-NETs) with elevated biochemical markers who have relapsed during or after receiving prior standard of care therapies, including octreotide, chemotherapy or targeted therapy.
To determine the efficacy and safety of robotic, laparoscopic and open surgery for enucleation of benign pancreatic neuroendocrine tumors
Well-differentiated neuroendocrine tumors (WDNETs) are uncommon neoplasms with an increasing number of new cases reported in the annual statistics of the Instituto Nacional de Cancerología (INC). The majority are advanced-stage presentations with limited chances of a complete surgical resection of the primary tumor, a clinical scenario where medical treatment options are also limited. In view of the characteristically defined expression of peptide receptors in WDNETs, radioactive molecular probes to target specific cellular receptors have been designed using radioisotopes with short range of penetration in tissues. We have designed a one-arm phase II prospective sequential clinical trial to assess the therapeutic efficacy of 177-Lu-[DOTA 0, Tyr 3] octreotate (177-Lu- DOTATATE) applied intravenously in three separate doses to patients with inoperable progressive WDNET. Selected patients matching inclusion criteria will be enrolled at the INC's Section of Endocrinology. Tumor response, treatment safety (side effects) and survival will be appraised. Data from clinical, biochemical and imaging follow-up will be periodically registered during treatment and until two years after the last infusion of 177Lu- DOTATATE. This phase II trial is justified because despite the fact that many preclinical and clinical studies have showed the potential usefulness of this novel palliative approach to treat patients with advanced-stage WDNETs there is a paucity of vigorous results to establish its efficacy as first-line treatment.
The study is designed as an open-label, prospective, single arm, multicenter study of everolimus in histologically confirmed, neuroendocrine carcinoma G3 /neuroendocrine tumor G3 after failure of first-line platin-based chemotherapy (open-label pilot study). The aim of this study is to provide a second line therapy to patients with any type of platinum based first line chemotherapy, to gather data on disease control rate and progression free survival.
