Filter by:The aim of the present project is to evaluate the frequency of distant metastases and clinically relevant relapse and mortality, respectively, of aNEN (Neuroendocrine Neoplasms of the Appendix) measuring 1 - 2 cm. The investigators hypothesize that the mortality rate of aNET (Neuroendocrine Tumors of the Appendix) measuring 1 - 2cm is less than 1%. Furthermore, the investigators hypothesize that regional lymph node metastases of aNET measuring 1 - 2 cm are clinically not relevant and are not associated with reduced survival. The investigators therefore hypothesize that oncological right-sided hemicolectomy has no impact on long-term survival after complete resection of aNET measuring 1 - 2 cm and that the malignant potential quo ad vitam of these tumors is lower than the risk of oncological hemicolectomy.
"The patient's journey" is an interview based study assessing the patients' experience from the first symptoms to a final diagnosis focusing on patients with small intestinal neuroendocrine tumors.
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 possibility and the safety of performing local therapy for Pancreatic neuroendocrine neoplasms (PanNENs) using radiofrequency ablation of the tumor under ultrasonography (EUS) guidance.
This study evaluates the efficacy of Long-acting Somastostatin analogs as treatment for type I gastric neuroendocrine tumors.
Aim: The aim of this study was to investigate the clinicopathological factors and to evaluate the prognostic accuracy of the new World Health Organization (WHO) 2017 grading system in pancreatic neuroendocrine tumor (PanNET) patients. Methods: Data collected between 1997 and December 2017 were analyzed. Histological grading and staging was based on the WHO 2017 grading system. Outcome after surgery and predictors of overall survival (OS) and disease free survival (DFS) were evaluated.
Neuroendocrine cancer remains a poorly known entity. Comprehensive treatment is multidisciplinary involving surgery, radiological and nuclear medicine, and medical. A national network for the management of sporadic and hereditary malignant neuro-ENdocrine Tumor (RENATEN) is in charged of coordinating this specific care. This is part of the French National Cancer INstitute (INCa) Rare Cancer Plan. The project is in the form of an analysis of elderly population (75 years or over) with a diagnosis of neuroendocrine cancer in the western part of the France (Brittany, Pays de Loire, Normandy, Center and a part of New Aquitaine areas) representing a population of more than 12 millions of inhabitants. Oncogeriatric evaluations, specialized meetings, ...would be analysed in order to improve the care of rare cancer patients.
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.
This phase II trial studies how well nivolumab and temozolomide work in treating patients with small-cell lung cancer that has come back or does not respond to treatment, or neuroendocrine cancer that has spread to other places in the body. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab and temozolomide may work better in treating patients with small-cell lung cancer and neuroendocrine cancer.
