Neuroendocrine tumours (NETs) are slow growing cancers, which commonly present as metastatic incurable disease. Some neuroendocrine tumours, termed functional NETs, overproduce hormones which result in a variety of symptoms. However, approximately 75% of NETs are considered non-functional meaning that they do not result in hormone overproduction. The main treatment for both functional and non-functional NETs is somatostatin analogues (SSA, a type of inhibitory hormone). These drugs slow tumour growth and reduce hormone production. Over time, the majority of patients will experience tumour growth despite treatment with SSA therapy. When this occurs, the addition of Peptide Receptor Radionuclide Therapy (PRRT, a type of targeted radiotherapy) in combination with ongoing SSA therapy is given. However, it is not known if continuing SSA therapy after commencement of PRRT is beneficial or not. The aim of this study is to estimate the outcomes of patients with grade 1 and 2 well differentiated mid and hind-gut neuroendocrine tumours who have progressed on SSA therapy and receive subsequent PRRT with or without concurrent SSA.
The research aims to prospectively include patients with GEP-NENs, undergo preoperative imaging assessment (including PET/CT and contrast-enhanced CT), and accurately delineate lymph node regions. Through postoperative pathological reports, the diagnostic performance of lymph node metastasis (LNM) in GEP-NENs is evaluated. Factors influencing the diagnostic accuracy of SSTR-PET/CT and contrast-enhanced CT are also investigated.
The aim of this multicenter, open-label, observational study is to evaluate the safety and efficacy of octreotide microspheres in the treatment of advanced neuroendocrine tumors in real clinical practice, especially to evaluate the treatment of octreotide microspheres in various subgroups of neuroendocrine tumor patients.
Recent studies show an increase in neuroendocrine neoplasms, especially for the digestive tract. Previous studies suggest various risk factors that were observed for various tumor sites, e.g. a family history of cancer, tobacco and alcohol consumption as well as metabolic disorders including diabetes and obesity. A risk factor that has been little studied to date is depressive disorders, which could increase the risk of neuroendocrine neoplasms either independently or through associated risk behaviors and/or antidepressant medication. The aim of this study is to identify risk factors for neuroendocrine neoplasms based on a case-control study in order to better understand the increase of neuroendocrine neoplasms in recent decades. The study is based on a record linkage of data from the Bavarian Cancer Registry and data from the Bavarian Association of Statutory Health Insurance Accredited Physicians. While the data from the Bavarian Cancer Registry enables the identification of neuroendocrine neoplasms on the basis of histopathological findings and thus is the basis for selecting cases, the claims data from the Bavarian Association of Statutory Health Insurance Accredited Physicians provides the source population as well data on diagnoses and thus enables the investigation of risk factors.
This research study is being conducted to improve the quality of care of participants who have a diagnosis of gastrointestinal cancer (anal, colon, rectal, esophageal, stomach, small bowel, appendix, pancreas, gall bladder, liver, neuroendocrine tumor of gastrointestinal origin). This study has 3 components as follows- 1. Ensuring appropriate biomarker testing and evidence-based care: Biomarkers are molecules in the tumor or blood that indicate normal or abnormal processes in participant's body and may indicate an underlying condition or disease. Various molecules, such as DNA (genes), proteins, or hormones, can serve as biomarkers since they all indicate something about participant's health. Biomarker testing can also help choose participant's treatment. Additionally, a tumor board will be conducted periodically to provide treatment recommendations to participant's treating physician. Participants will receive standard-of-care treatment if participant enroll in this study. Participant will not receive any experimental treatment. 2. Assistance with clinical trial enrollment. The study team will help participants enroll in a clinical trial appropriate for participant's condition. However, enrolling in a clinical trial is totally up to the participant. 3. Health literacy: The study team will provide information relevant to participant's diagnosis to enrich participant's understanding of participant's condition and treatment. Investigator will provide questionnaires to assess participant's understanding before and after participant's have been provided with educational/informational material appropriate for participant's diagnosis.
Participants of this study are adults with GEP-NETs and/or acromegaly who were using the Ipsen lanreotide syringe and have transitioned in the last 6 months to the Pharmathen lanreotide syringe, having received at least two injections using the Pharmathen syringe. GEP-NETs are abnormal growths that develop in the digestive system, including the stomach, intestines, and pancreas. These tumors arise from special cells called neuroendocrine cells, which are found in these organs and release hormones to regulate various bodily functions. GEP-NETs can be slow-growing, and symptoms may vary depending on their location and size. Acromegaly is a condition where a person's body produces too much growth hormone. This excess hormone can cause certain body parts, like the hands, feet, and face, to enlarge over time. It typically occurs because of a tumor on the pituitary gland in the brain, which is responsible for regulating hormones. Acromegaly can lead to various health issues if not treated, but medications or surgery can often help manage the condition. Long-acting somatostatin analogs (LA-SSAs) are indicated for patients with Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) and acromegaly who are not eligible for surgery or when surgery fails to achieve remission. Data for this study will be collected after the treatment switch from the Ipsen lanreotide syringe to the Pharmathen lanreotide syringe has occurred, using one round of one-to-one qualitative telephone and/or videoconference interviews with patients. Interviews will last 45 minutes and be carried out in the local language of the participant's country. The main aim of this study is to capture the patient experience of the Ipsen lanreotide syringe and their experience with the Pharmathen lanreotide syringe.
The purpose of this study is to explore whether chemotherapy and targeted-therapy regimens guided by organoid drug sensitivity test can improve the outcomes of non-resectable locally advanced and metastatic Pancreatic neuroendocrine tumors. At the same time, this study will evaluate the successful stablishment rate of organoid from biopsy tissue , and explore the concordance between drug sensitivity test results and patients' treatment response
This is an open label, single arm, phase II multicentre study designed to evaluate the efficacy and safety of pembrolizumab in combination with carboplatin and etoposide chemotherapy followed by pembrolizumab and lenvatinib maintenance therapy in patients with HG-NETs who are chemotherapy-naïve for their metastatic disease. The study will be conducted in up to 10 sites and will recruit up to a maximum of 20 evaluable participants.
This phase II trial compares the safety and effect of temozolomide combined with survivin long peptide vaccine (SurVaxM) to temozolomide alone in patients with neuroendocrine tumors (NET) that has spread from where it first started (primary site) to other places in the body (metastatic) and is growing, spreading or getting worse (progressing). Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid and may kill tumor cells and slow down or stop tumor growth. Survivin, a protein, is expressed in 50% of patients that have neuroendocrine tumors and, is associated with poor outcomes. SVN53-67/M57-KLH peptide vaccine (SurVaxM) is a vaccine that has been shown to produce an immune system response against cancer cells that express a survivin and may block the growth of new tumor cells. Giving temozolomide with SurVaxM may kill more tumor cells in patients with progressing metastatic neuroendocrine tumors.
